NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. DESCRIPTION OF BUSINESS

For more than a century, Huntington Ingalls Industries, Inc. ("HII" or the "Company") has been designing, building, overhauling and repairing ships primarily for the U.S. Navy and the U.S. Coast Guard. The Company conducts business primarily with the U.S. Government, principally the Department of Defense ("DoD"). As prime contractor, principal subcontractor, team member or partner, HII participates in many high-priority U.S. defense technology programs. HII is organized into three reportable segments: Ingalls, Newport News, and Other. Through its Ingalls segment, HII is a builder of amphibious assault and expeditionary ships for the U.S. Navy, the sole builder of National Security Cutters for the U.S. Coast Guard, and one of only two companies that builds the Navy's current fleet of DDG-51 Arleigh Burke-class destroyers. Through its Newport News segment, HII is the nation's sole designer, builder and refueler of nuclear-powered aircraft carriers, and one of only two companies currently designing and building nuclear-powered submarines for the U.S. Navy. The Other segment was established in the second quarter of 2014 to account for certain of the Company's non-shipbuilding commercial activities.

2. BASIS OF PRESENTATION

Principles of Consolidation - The unaudited condensed consolidated financial statements of HII and its subsidiaries have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and the instructions to Form 10-Q promulgated by the Securities and Exchange Commission ("SEC"). All intercompany transactions and balances are eliminated in consolidation. For classification of current assets and liabilities related to its long-term production contracts, the Company uses the duration of these contracts as its operating cycle, which is generally longer than one year.

These unaudited condensed consolidated financial statements include all adjustments of a normal recurring nature considered necessary by management for a fair presentation of the unaudited condensed consolidated financial position, results of operations, and cash flows. These unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2014.

The quarterly information is labeled using a calendar convention; that is, first quarter is consistently labeled as ending on March 31, second quarter as ending on June 30, and third quarter as ending on September 30. It is management's long-standing practice to establish interim closing dates using a "fiscal" calendar, which requires the businesses to close their books on a Friday near these quarter-end dates in order to normalize the potentially disruptive effects of quarterly closings on business processes. The effects of this practice only exist for interim periods within a reporting year.

Accounting Estimates - The preparation of the Company's unaudited condensed consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Estimates have been prepared on the basis of the most current and best available information and actual results could differ materially from those estimates.

The Bipartisan Budget Act of 2013 established budget top lines and provided sequestration relief for 2014 and 2015. Sequestration remains in effect for 2016 through 2021 and could result in significant decreases in DoD spending that could negatively impact the Company's revenues and its estimated recovery of goodwill and other long-lived assets.

Revenue Recognition - The majority of the Company's business is derived from long-term contracts for the construction of naval vessels, production of goods, and provision of services to the federal government, principally the U.S. Navy. In accounting for these contracts, the Company extensively utilizes the cost-to-cost measure of the percentage-of-completion method of accounting, principally based upon total costs incurred. Under this method, sales, including estimated earned fees or profits, are recorded as costs are incurred, generally based on the percentage that total costs incurred bear to total estimated costs at completion. For certain contracts that provide for deliveries of a substantial number of similar units, sales are accounted for using units of delivery as the basis to measure progress toward completion. Certain contracts contain provisions for price redetermination or for cost and/or performance incentives. Such redetermined amounts or incentives are included in sales when the amounts can

5

reasonably be determined and estimated. Amounts representing contract change orders, claims, requests for equitable adjustment, or limitations in funding are included in sales only when they can be reliably estimated and realization is probable. The Company is accounting for one of its contracts under the percentage-of-completion method based on a zero profit margin and will continue such accounting until results can be estimated more precisely. Revenues related to this contract represent less than 1% of the Company's total revenues for the three months endedMarch 31, 2015. The Company estimates profit as the difference between total estimated revenues and total estimated cost of a contract and recognizes that profit over the life of the contract based on progress toward completion. If the Company estimates a contract will result in a loss, the full amount of the estimated loss is recognized against income in the period in which the loss is identified. The Company classifies contract revenues as product sales or service revenues depending upon the predominant attributes of the relevant underlying contracts.

The Company recognizes changes in estimates of contract sales, costs, and profits using the cumulative catch-up method of accounting. This method recognizes in the current period the cumulative effect of the changes on current and prior periods. Accordingly, the effect of the changes on future periods of contract performance is recognized as if the revised estimate had been the original estimate. For the three months endedMarch 31, 2015 and 2014, net cumulative catch-up adjustments increased operating income by $55 million and $44 million, respectively, and increased diluted earnings per share by $0.73 and $0.58, respectively. No individual adjustment was material to the Company's consolidated statements of operations and comprehensive income in any of these periods.

The Company also enters into other types of contracts such as certain services or commercial arrangements. For such contracts not associated with the design, development, manufacture, or modification of complex equipment, revenues are recognized upon delivery or as services are rendered once persuasive evidence of an arrangement exists, the price is fixed or determinable, and collectibility is reasonably assured. Costs related to these contracts are expensed as incurred.

Fair Value of Financial Instruments - Except for long-term debt and available-for-sale securities held in trust, the carrying amounts of the Company's financial instruments recorded at historical cost approximate fair value due to the short-term nature of the instruments and low credit risk associated with the respective counterparties.

The Company maintains multiple rabbi trusts established to fund certain non-qualified pension plans. These trusts consist of available-for-sale investments primarily in marketable securities. The assets are held at fair value, and a significant majority of investments held in the trusts are valued within Level 1 of the fair value hierarchy and no material amounts are valued within Level 3 of the fair value hierarchy. The rabbi trusts were valued at $46 million and $45 million as of March 31, 2015, and December 31, 2014, respectively, and are presented within miscellaneous other assets within the unaudited condensed consolidated statements of financial position.

3. ACCOUNTING STANDARDS UPDATES

On April 7, 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-03, "Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs." The update requires the presentation of capitalized debt issuance costs as a direct reduction of the related debt liability, consistent with the current required presentation of debt discounts. The standard is effective for public entities for annual reporting periods beginning after Dec. 15, 2015, and interim periods within those periods. The Company does not expect the adoption of ASU 2015-03 to have a material impact on the Company's consolidated financial position, results of operations, or cash flows.

On May 28, 2014, the FASB issued the final standard on revenue from contracts with customers. The standard, issued as ASU 2014-09, outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the standard is that "an entity shall recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services." The standard provides a five-step analysis of transactions to determine when and how revenue should be recognized. The five steps are: Identify the contract with the customer; Identify the performance obligations in the contract; Determine the transaction price; Allocate the transaction price to the performance obligations; and Recognize revenue when or as each performance obligation is satisfied. The standard also includes disclosure requirements to provide greater insight into both revenue that has been recognized and revenue that is expected to be recognized in the future from existing contracts, as well as quantitative and qualitative information about significant judgments and changes in the judgments that management

6

made to determine revenue that is recorded. The guidance permits the use of either a retrospective or cumulative effect transition method. As approved, ASU 2014-09 will be effective for public entities for annual reporting periods, including interim reporting periods within those periods, beginning after December 15, 2016 and does not permit early application. On April 1, 2015, the FASB voted to propose a deferral of the effective date of the new revenue recognition standard by one year. Based on the FASB's proposed decision, public entities would apply the new revenue standard to annual reporting periods beginning after December 15, 2017, but early adoption for annual reporting periods beginning after December 31, 2016, would be permitted. The Company is currently evaluating the impact that will result from the implementation of ASU 2014-09 on its financial statements and disclosures, contracting and accounting processes, internal controls, and information technology systems.

4. AVONDALE

In 2010, plans were announced to consolidate the Company's Ingalls shipbuilding operations by winding down shipbuilding at the Avondale, Louisiana facility in 2013 after completion of LPD-class ships that were under construction at this facility. In October 2014, the Company ceased shipbuilding construction operations at the Avondale facility. The consolidation is intended to reduce costs, increase efficiency, and address shipbuilding overcapacity.

In connection with and as a result of the decision to wind down shipbuilding at the Avondale facility, the Company began incurring and paying related costs, including, but not limited to, severance expense, relocation expense, and asset write-downs related to the Avondale facilities. Management's current estimate of these expenditures is $287 million. Such costs are expected to be recoverable under existing flexibly-priced contracts or future negotiated contracts in accordance with Federal Acquisition Regulation ("FAR") provisions for the treatment of restructuring and shutdown related costs. The Company is currently in discussions with the U.S. Navy regarding its cost submission to support the recoverability of these costs under the FAR and applicable contracts.

The Defense Contract Audit Agency ("DCAA"), a DoD agency, prepared an initial audit report on the Company's July 2010 cost proposal for restructuring and shutdown related costs of $310 million, which stated that the proposal was not adequately supported for the DCAA to reach a conclusion and questioned approximately $25 million, or 8%, of the costs submitted by the Company. In July 2014, the Company received a letter from the Supervisor of Shipbuilding requesting that the Company revise its restructuring proposal to address certain documentation issues identified by the DCAA in order for the Government to make an adequate evaluation of the restructuring proposal. In August 2014, the Company received a letter from the Supervisor of Shipbuilding proposing a joint meeting regarding the treatment of specific costs included in the restructuring proposal and acknowledging that the allowability and allocability of costs will be determined by the Government in an Advanced Agreement in accordance with FAR. The Company submitted a revised proposal in March 2015 to address the concerns of the DCAA and to reflect a revised estimated total cost of $287 million.

Ultimately, the Company anticipates agreement with the U.S. Navy that is substantially in accordance with management's cost recovery expectations. Accordingly, HII has treated these costs as allowable costs in determining the earnings performance on its contracts in process. The actual restructuring expenses related to the wind down may be greater than the Company's current estimate, and any inability to recover such costs could result in a material effect on the Company's consolidated financial position, results of operations or cash flows.

The Company also evaluated the effect that the wind down of the Avondale facilities might have on the benefit plans in which HII employees participate. HII determined that the impact of a curtailment and other resulting adjustments in these plans was not material to its consolidated financial position, results of operations or cash flows.

As of March 31, 2015, and December 31, 2014, $203 million and $212 million, respectively, of restructuring and shutdown related costs were capitalized in inventoried costs. As of March 31, 2015, and December 31, 2014, $52 million and $48 million, respectively, of accounts receivable was related to restructuring and shutdown related costs. For each of the three months endedMarch 31, 2015 and 2014, the Company expensed $14 million of these costs as part of general and administrative expenses. As of March 31, 2015 and December 31, 2014, there were no accrued liabilities for restructuring and shutdown related costs associated with winding down the Avondale facility and no payments or adjustments were made for the three months endedMarch 31, 2015.

The following table summarizes the changes in the Company's liability for restructuring and shutdown related costs associated with winding down the Avondale facility for the three months endedMarch 31, 2014. As of March 31,

7

2014, these costs were comprised primarily of employee severance and retention payments, as well as incentive bonuses.

5. GULFPORT

In September 2013, the Company announced the closure of its Gulfport Composite Center of Excellence in Gulfport, Mississippi, part of the Ingalls reportable segment, which it completed in August 2014. In connection with this closure, the Company incurred total costs of approximately $54 million, consisting of approximately $52 million in accelerated depreciation of fixed assets and $2 million in personnel, facility shutdown, and other related costs. In July 2014, the Company received a letter from the Supervisor of Shipbuilding taking exception to the Company's treatment of the Gulfport closure costs. The Company disagrees with the conclusion reached by the Supervisor of Shipbuilding and is currently evaluating its future course of action. The inability to recover Gulfport closure costs could result in a material effect on the Company's consolidated financial position, results of operations, or cash flows. As of March 31, 2015, and December 31, 2014, $35 million and $37 million, respectively, of accounts receivable was related to Gulfport closure costs. In March 2015, the Company sold the Gulfport Composite Center of Excellence to the Mississippi State Port Authority for a price of $32 million, resulting in a gain on disposition of $9 million, recorded as a reduction to contract costs in accordance with the terms of the Company’s contracts with the U.S. Government.

6. ACQUISITIONS

On January 30, 2015, the Company acquired, for approximately $6 million in cash, the assets of the Engineering Solutions Division ("ESD") of The Columbia Group. ESD, a leading designer and builder of unmanned underwater vehicles for domestic and international customers, will operate as the Undersea Solutions Group ("USG"). As the U.S. Navy increases employment of unmanned vehicles in both the surface and undersea domains, this acquisition will enhance the Company's ability to compete in these markets. In connection with this acquisition, the Company recorded $5 million of goodwill, all of which was allocated to its Newport News segment, primarily attributed to USG's specialized and skilled employees. See Note 11: Goodwill and Other Purchased Intangible Assets. The assets, liabilities, and results of operations of USG are not material to the Company’s consolidated financial position, results of operations, or cash flows. The Company has not completed the purchase price allocation due to the recent acquisition date and potential adjustments upon finalization of the fair value of the assets acquired and liabilities assumed.

On May 30, 2014, the Company acquired, for approximately $225 million in cash, net of $5 million of cash acquired, UniversalPegasus International Holdings, Inc. ("UPI"), a provider of project management, engineering and construction management services to the oil and gas industry. The acquisition was consistent with the Company's strategy to utilize its engineering and energy related expertise to expand its position in energy infrastructure markets. In connection with this acquisition, the Company recorded $150 million of goodwill, all of which was allocated to its Other segment, primarily related to the value of UPI’s workforce, and $41 million of intangible assets related to contractual relationships and trade names. See Note 11: Goodwill and Other Purchased Intangible Assets. Adjustments to the fair value of assets acquired and liabilities assumed since the acquisition date were not material and were primarily driven by the finalization of the net working capital adjustment and refinement of fair value calculations for certain assets and liabilities. The Company has not completed the purchase price allocation due to potential adjustments upon finalization of the fair value of certain tax assets and liabilities. The assets, liabilities, and results of operations of UPI are not material to the Company’s consolidated financial position, results of operations, or cash flows.

On January 2, 2014, the Company acquired, for approximately $47 million in cash, net of $6 million of cash acquired, The S.M. Stoller Corporation, renamed as Stoller Newport News Nuclear, Inc. ("SN3"), a provider of environmental, nuclear, and technical consulting and engineering services to the Department of Energy, Department of Defense, and private sector. The acquisition was consistent with the Company's strategy to utilize its nuclear and energy related expertise developed through its shipbuilding activities to expand its position in the

8

energy marketplace. In connection with this acquisition, the Company recorded $42 million of goodwill, all of which was allocated to its Newport News segment, primarily attributed to SN3's specialized and skilled employees, and $6 million of intangible assets, primarily related to existing contract backlog and trade names. See Note 11: Goodwill and Other Purchased Intangible Assets. The assets, liabilities, and results of operations of SN3 are not material to the Company’s consolidated financial position, results of operations, or cash flows.

The Company funded each of these acquisitions using cash on hand. The acquisition costs incurred in connection with these acquisitions were not material. The operating results of these businesses have been included in the Company’s consolidated results as of the respective closing dates of the acquisitions. In allocating the purchase price of these businesses, the Company considered the estimated fair value of net tangible and intangible assets acquired, with any excess purchase price recorded as goodwill. The total amount of goodwill resulting from these acquisitions expected to be deductible for tax purposes was $96 million. Pro forma revenues and results of operations have not been provided for these acquisitions as they are not material either individually or in the aggregate.

Treasury Stock - In 2014, the Company's board of directors authorized an increase in the Company's stock repurchase program from $300 million to $600 million and an extension of the term of the program to October 31, 2019. Repurchases are made from time to time at management's discretion in accordance with applicable federal securities laws. For the three months endedMarch 31, 2015, the Company repurchased 210,240 shares at a cost of $29 million. For the three months endedMarch 31, 2014, the Company repurchased 247,551 shares at a cost of $25 million, of which approximately $15 million was not yet settled for cash as of March 31, 2014.

Accumulated Other Comprehensive Income - Other comprehensive income (loss) refers to gains and losses recorded as an element of stockholders' equity but excluded from net earnings (loss). The accumulated other comprehensive loss as of March 31, 2015 and December 31, 2014, was comprised of unamortized benefit plan costs of $850 million and $864 million, respectively, and other comprehensive income items of $1 million and $2 million, respectively. The changes in accumulated other comprehensive income (loss) by component for the three months endedMarch 31, 2015 and 2014, were as follows:

¹ These accumulated comprehensive income (loss) components are included in the computation of net periodic benefit cost. See Note 17: Employee Pension and Other Postretirement Benefits. The tax benefit associated with amounts reclassified from accumulated other comprehensive income (loss) for the three months endedMarch 31, 2015 and 2014, was $8 million and $3 million, respectively.

8. EARNINGS PER SHARE

Basic and diluted earnings per common share were calculated as follows:

	Three Months Ended March 31
(in millions, except per share amounts)	2015		2014
Net earnings (loss)	$	87	$	90
Weighted-average common shares outstanding	48.4		49.1
Net dilutive effect of stock options and awards	0.3		0.6
Dilutive weighted-average common shares outstanding	48.7		49.7
Earnings (loss) per share - basic	$	1.80	$	1.83
Earnings (loss) per share - diluted	$	1.79	$	1.81

The Company's calculation of diluted earnings per common share includes the dilutive effects of the assumed exercise of stock options and vesting of restricted stock based on the treasury stock method. Under this method, the Company has excluded the effects of 0.3 million stock options and 0.8 millionRestricted Performance Stock Rights ("RPSRs") from the diluted share amounts presented above for the three months endedMarch 31, 2015. The amounts presented above for the three months endedMarch 31, 2014, exclude the impact of 0.5 million stock options, 0.3 million Restricted Stock Rights ("RSRs") and 1.2 million RPSRs under the treasury stock method.

11. GOODWILL AND OTHER PURCHASED INTANGIBLE ASSETS

Goodwill

HII performs impairment tests for goodwill as of November 30 of each year and between annual impairment tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the Company's reporting units below their carrying value.

Accumulated goodwill impairment losses as of both March 31, 2015, and December 31, 2014, were $2,802 million. The accumulated goodwill impairment losses for Ingalls as of each of March 31, 2015, and December 31, 2014, were $1,568 million. The accumulated goodwill impairment losses for Newport News as of each of March 31, 2015, and December 31, 2014, were $1,187 million. The accumulated goodwill impairment losses for the Other segment as of each of March 31, 2015, and December 31, 2014, were $47 million.

Adjustments	—		—		1		1
Balance as of March 31, 2015	$	175	$	753	$	104	$	1,032

Purchased Intangible Assets

In connection with the UPI purchase in 2014, the Company recorded $41 million of intangible assets pertaining to existing contracts, trademarks, and trade names to be amortized using the pattern of benefits method over a weighted-average life of 11 years. In connection with the SN3 purchase in 2014, the Company recorded $6 million of intangible assets pertaining to existing contract backlog, trademarks, and trade names to be amortized using the pattern of benefits method over a weighted-average life of five years.

The following table summarizes the Company's aggregate purchased intangible assets, which are primarily program related intangible assets.

($ in millions)	March 31 2015			December 31 2014
Gross carrying amount	$	986		$	986
Accumulated amortization	(446		)	(439		)
Net carrying amount	$	540		$	547

The Company's purchased intangible assets are being amortized on a straight-line basis or a method based on the pattern of benefits. Net intangible assets consist principally of amounts pertaining to nuclear-powered aircraft carrier and submarine program intangibles, with an aggregate weighted-average useful life of 40 years based on the long life cycle of the related programs. Aggregate amortization expense was $7 million and $6 million for the three months endedMarch 31, 2015 and 2014, respectively.

The Company expects amortization expense for purchased intangible assets of approximately $26 million in 2015, $25 million in each of the years 2016 and 2017, and $24 million in each of the years 2018 and 2019.

12. INCOME TAXES

The Company's earnings are principally domestic and its effective tax rates on earnings from operations for the three months endedMarch 31, 2015 and 2014, were 34.6% and 31.8%, respectively. The higher effective tax rate for the three months endedMarch 31, 2015, was primarily attributable to the non-recurring tax benefit resulting from the release of uncertain tax positions due to expiration of the statute of limitations during the three months endedMarch 31, 2014.

For the three months endedMarch 31, 2015, the Company's effective tax rate differed from the federal statutory rate primarily as a result of the domestic manufacturing deduction. For the three months endedMarch 31, 2014, the Company's effective tax rate differed from the federal statutory rate primarily as a result of the domestic manufacturing deduction and a non-recurring tax benefit resulting from the release of uncertain tax positions due to expiration of the statute of limitations.

Deferred state income taxes reflect the change in deferred state assets and liabilities in the relevant period. These amounts are recorded within operating income, while the current period state income tax expense is charged to contract costs and included in cost of sales and service revenues in segment operating income.

Net deferred tax assets (liabilities) as presented in the unaudited condensed consolidated statements of financial position were as follows:

($ in millions)	March 31 2015		December 31 2014
Net current deferred tax assets	$	132	$	129
Net non-current deferred tax assets	203		212
Total net deferred tax assets	$	335	$	341

13. DEBT

Long-term debt consisted of the following:

($ in millions)	March 31 2015		December 31 2014
Term loan due March 30, 2016	$	395	$	395
Senior notes due March 15, 2021, 7.125%	600		600

Total long-term debt	1,700		1,700
Less current portion	108		108
Long-term debt, net of current portion	$	1,592	$	1,592

Credit Facility - In March 2011, the Company entered into the Credit Facility with third-party lenders. The Credit Facility is comprised of a five-year term loan facility of $575 million, which was funded on March 30, 2011, and a revolving credit facility of $650 million, which may be drawn upon during a period of five years from the date of the funding. The revolving credit facility includes a letter of credit subfacility of $350 million and a swingline loan subfacility of $100 million. In November 2013, the Company amended and restated its existing Credit Facility to provide more favorable pricing terms and more flexibility under the Credit Facility’s restricted payment covenants. The term loan and revolving credit facility have a variable interest rate on outstanding borrowings based on the London Interbank Offered Rate ("LIBOR") plus a spread based upon the Company's leverage ratio. As of March 31, 2015, the spread was 1.5% and may vary between 1.5% and 2.5%. The revolving credit facility also has a commitment fee rate on the unutilized balance based on the Company's leverage ratio. As of March 31, 2015, this fee rate was 0.25% and may vary between 0.25% and 0.45%. As of March 31, 2015, approximately $30 million in letters of credit were issued but undrawn, and the remaining $620 million of the revolving credit facility was unutilized.

13

The term loan facility requires principal payments in three-month intervals from the funding date. Payments were made in aggregate amounts equal to 5% of the original principal balance during each of the first year and the second year, 10% during the third year, and are expected to be made in aggregate amounts equal to 15% during the fourth year, and 65% during the fifth year of which 5% is payable on each of the first three quarterly payment dates during such year, and the balance is payable on the term maturity date.

Senior Notes - In March 2011, the Company issued $600 million aggregate principal amount of 6.875% senior notes due March 15, 2018, and $600 million aggregate principal amount of 7.125% senior notes due March 15, 2021. In December 2014, the Company issued $600 million aggregate principal amount of 5.000% senior notes due December 15, 2021. The net proceeds from the issuance of these senior notes were used to repurchase the Company's 6.875% senior notes due March 15, 2018.

Mississippi Economic Development Revenue Bonds - As of March 31, 2015, the Company had $84 million outstanding under Industrial Revenue Bonds issued by the Mississippi Business Finance Corporation. These bonds accrue interest at a fixed rate of 7.81% and mature in 2024.

Gulf Opportunity Zone Industrial Development Revenue Bonds - As of March 31, 2015, the Company had $21 million outstanding under Gulf Opportunity Zone Industrial Development Revenue Bonds issued by the Mississippi Business Finance Corporation. These bonds accrue interest at a fixed rate of 4.55% and mature in 2028.

The Company's debt arrangements contain customary affirmative and negative covenants, including a maximum total leverage ratio and a minimum interest coverage ratio. The Company was in compliance with all debt covenants during the three months endedMarch 31, 2015.

The estimated fair value of the Company's total long-term debt, including current portions, as of March 31, 2015 and December 31, 2014, was $1,804 million and $1,779 million, respectively. The fair value of the Company's long-term debt was calculated based on either recent trades of the Company's debt instruments in inactive markets or yields available on debt with substantially similar risks, terms and maturities, which fall within Level 2 under the fair value hierarchy.

14. INVESTIGATIONS, CLAIMS, AND LITIGATION

The Company is involved in legal proceedings before various courts and administrative agencies, and is periodically subject to government examinations, inquiries and investigations. Pursuant to FASB Accounting Standards Codification 450 Contingencies, the Company has accrued for losses associated with investigations, claims and litigation when, and to the extent that, loss amounts related to the investigations, claims and litigation are probable and can be reasonably estimated. The actual losses that might be incurred to resolve such investigations, claims and litigation may be higher or lower than the amounts accrued. For matters where a material loss is probable or reasonably possible and the amount of loss cannot be reasonably estimated, but the Company is able to reasonably estimate a range of possible losses, the Company will disclose such estimated range in these notes. This estimated range is based on information currently available to the Company and involves elements of judgment and significant uncertainties. Any estimated range of possible loss does not represent the Company's maximum possible loss exposure. For matters as to which the Company is not able to reasonably estimate a possible loss or range of loss, the Company will indicate the reasons why it is unable to estimate the possible loss or range of loss. For matters not specifically described in these notes, the Company does not believe, based on information currently available to it, that it is reasonably possible that the liabilities, if any, arising from such investigations, claims and litigation will have a material effect on its consolidated financial position, results of operations or cash flows. The Company has, in certain cases, provided disclosure regarding certain matters for which the Company believes at this time that the likelihood of material loss is remote.

False Claims Act Complaint - In January 2011, the U.S. Department of Justice ("DoJ") first informed the Company through Northrop Grumman of a False Claims Act complaint (the "Complaint") that was filed under seal in the U.S. District Court for the District of Columbia. The redacted copy of the Complaint the Company received alleges that, through largely unspecified fraudulent means, the Company and Northrop Grumman obtained federal funds that were restricted by law for the consequences of Hurricane Katrina, and used those funds to cover costs under certain shipbuilding contracts that were unrelated to Katrina and for which Northrop Grumman and the Company were not entitled to recovery under the contracts. The Complaint seeks monetary damages of at least $835 million, plus penalties, attorneys' fees and other costs of suit. Damages under the False Claims Act may be trebled upon a finding of liability.

14

In July 2012, the District Court entered an order permitting the Company to disclose certain information not included in the redacted copy of the Complaint received by the Company, including the date the Complaint was filed, the decision of the DoJ to decline intervention in the case, and the principal parties involved in the case. The Complaint was filed on June 2, 2010, by relators Gerald M. Fisher and Donald C. Holmes. In December 2011, the DoJ filed a Notice of Election to Decline Intervention in the case. As of August 29, 2012, Gerald M. Fisher was no longer a relator in or party to this case. In February 2013, the U.S. District Court for the District of Columbia granted the defendants' motion to transfer venue, and the case was transferred to the U.S. District Court for the Southern District of Mississippi. The Company has filed a motion to dismiss the case and a motion to disqualify relator Holmes, and all other matters are stayed pending resolution of the motion to dismiss.

Based upon a review to date of the information available to the Company, the Company believes that it has substantive defenses to the allegations in the Complaint, that the claims as set forth in the Complaint evidence a fundamental lack of understanding of the terms and conditions in the Company's shipbuilding contracts, including the post-Katrina modifications to those contracts, and the manner in which the parties performed in connection with the contracts, and that the claims as set forth in the Complaint lack merit. The Company, therefore, believes that the claims as set forth in the Complaint will not result in a material effect on its consolidated financial position, results of operations or cash flows. The Company intends to defend the matter vigorously, but the Company cannot predict what new or revised claims might be asserted or what information might come to light and can, therefore, give no assurances regarding the ultimate outcome.

U.S. Government Investigations and Claims - Departments and agencies of the U.S. Government have the authority to investigate various transactions and operations of the Company, and the results of such investigations may lead to administrative, civil or criminal proceedings, the ultimate outcome of which could be fines, penalties, repayments or compensatory, treble, or other damages. U.S. Government regulations provide that certain findings against a contractor may also lead to suspension or debarment from future U.S. Government contracts or the loss of export privileges. Any suspension or debarment would have a material effect on the Company because of its reliance on government contracts.

In January 2013, the Company disclosed to the DoD, including the U.S. Navy, and the U.S. Department of Homeland Security, including the U.S. Coast Guard, pursuant to the FAR, that it had initiated an internal investigation regarding whether certain employees at Ingalls mischarged time or misstated progress on Navy and Coast Guard contracts. The Company conducted an internal investigation, led by external counsel, and has taken remedial actions, including the termination of employees in instances where the Company believed grounds for termination existed. The Company is providing information regarding its investigation to the relevant government agencies. The Company agreed with the U.S. Navy and U.S. Coast Guard that they would initially withhold $24 million in payments on existing contracts pending receipt of additional information from the Company's internal investigation. The U.S. Navy has reduced its portion of the withhold from $18.2 million to $4.7 million, while expressing its view that the gross amount of potential mischarging incurred by the Navy will likely not exceed $3.1 million. The U.S. Coast Guard informed the Company in June 2014 that it was provisionally reducing its withhold from $5.8 million to $3.6 million. Based on the results of its internal investigation, the Company estimates that the maximum amount of U.S. Navy and Coast Guard mischarging is approximately $4 million. 

The Company is continuing discussions with its U.S. Government customers regarding the potential release of an additional portion of the withheld funds, but the Company cannot predict whether or when these customers will agree to any additional release of the withhold amount. Depending upon the U.S. Government's assessment of the matters under investigation, the Company could be subject to significant civil penalties, criminal fines, and suspension or debarment from U.S. Government contracting. Although the Company does not currently believe that this matter will have a material effect on its financial condition, results of operations or cash flows, the Company cannot predict what new information might come to light in the future and can therefore give no assurances regarding the ultimate outcome of this matter.

Asbestos Related Claims - HII and its predecessors-in-interest are defendants in a longstanding series of cases that have been and continue to be filed in various jurisdictions around the country, wherein former and current employees and various third parties allege exposure to asbestos containing materials while on or associated with HII premises or while working on vessels constructed or repaired by HII. The cases allege various injuries, including those associated with pleural plaque disease, asbestosis, cancer, mesothelioma and other alleged asbestos related conditions. In some cases, several of HII's former executive officers are also named as defendants. In some instances, partial or full insurance coverage is available to the Company for its liability and that of its former

15

executive officers. Although the Company believes the ultimate resolution of these cases will not have a material effect on its consolidated financial position, results of operations or cash flows, it cannot predict what new or revised claims or litigation might be asserted or what information might come to light and can, therefore, give no assurances regarding the ultimate outcome of asbestos related litigation.

Other Litigation - The Company and its predecessor-in-interest have been in litigation with the Bolivarian Republic of Venezuela (the “Republic”) since 2002 over a contract for the repair, refurbishment and modernization at Ingalls of two foreign-built frigates. The case proceeded towards arbitration, then appeared to settle favorably, but the settlement was overturned in court and the matter returned to litigation. In March 2014, the Company filed an arbitral statement of claim asserting breaches of the contract and $173 million in damages plus substantial interest and litigation expenses. In July 2014, the Republic filed in the arbitration a statement of defense denying all the Company’s allegations and a counterclaim alleging late redelivery of the frigates, unfinished work and breach of warranty and asserting damages of $61 million plus interest. An arbitration hearing was held in January 2015. No assurances can be provided regarding the ultimate outcome of this matter.

The Company is party to various claims and legal proceedings that arise in the ordinary course of business. Although the Company believes that the resolution of any of these various claims and legal proceedings will not have a material effect on its consolidated financial position, results of operations or cash flows, it cannot predict what new or revised claims or litigation might be asserted or what information might come to light and can, therefore, give no assurances regarding the ultimate outcome of these matters.

15. COMMITMENTS AND CONTINGENCIES

Contract Performance Contingencies - Contract profit margins may include estimates of revenues not contractually agreed to between the customer and the Company for matters such as settlements in the process of negotiation, contract changes, claims and requests for equitable adjustment for previously unanticipated contract costs. These estimates are based upon management's best assessment of the underlying causal events and circumstances, and are included in determining contract profit margins to the extent of expected recovery based on contractual entitlements and the probability of successful negotiation with the customer. As of March 31, 2015, the recognized amounts related to claims and requests for equitable adjustment are not material individually or in aggregate.

Guarantees of Performance Obligations - From time to time in the ordinary course of business, HII may enter into joint ventures, teaming and other business arrangements to support the Company's products and services. The Company generally strives to limit its exposure under these arrangements to its investment in the arrangement, or to the extent of obligations under the applicable contract. In some cases, however, HII may be required to guarantee performance of the arrangement's obligations and, in such cases, generally obtains cross-indemnification from the other members of the arrangement. As of March 31, 2015, the Company was not aware of any existing event of default that would require HII to satisfy any of these guarantees.

Environmental Matters -The estimated cost to complete environmental remediation has been accrued where it is probable that the Company will incur such costs in the future to address environmental conditions at currently or formerly owned or leased operating facilities, or at sites where it has been named a Potentially Responsible Party ("PRP") by the Environmental Protection Agency or similarly designated by another environmental agency, and the related costs can be estimated by management. These accruals do not include any litigation costs related to environmental matters, nor do they include amounts recorded as asset retirement obligations. To assess the potential impact on the Company's consolidated financial statements, management estimates the range of reasonably possible remediation costs that could be incurred by the Company, taking into account currently available facts on each site, as well as the current state of technology and prior experience in remediating contaminated sites. These estimates are reviewed periodically and adjusted to reflect changes in facts and technical and legal circumstances. Management estimates that as of March 31, 2015, the probable future cost for environmental remediation is $2 million, which is accrued in other current liabilities. Factors that could result in changes to the Company's estimates include: modification of planned remedial actions, increases or decreases in the estimated time required to remediate, changes to the determination of legally responsible parties, discovery of more extensive contamination than anticipated, changes in laws and regulations affecting remediation requirements, and improvements in remediation technology. Should other PRPs not pay their allocable share of remediation costs, the Company may incur costs exceeding those already estimated and accrued. In addition, there are certain potential remediation sites where the costs of remediation cannot be reasonably estimated. Although management cannot predict whether new information gained as projects progress will materially affect the

16

estimated liability accrued, management does not believe that future remediation expenditures will have a material effect on the Company's consolidated financial position, results of operations or cash flows.

Financial Arrangements - In the ordinary course of business, HII uses standby letters of credit issued by commercial banks and surety bonds issued by insurance companies principally to support the Company's self-insured workers' compensation plans. As of March 31, 2015, the Company had $30 million in standby letters of credit issued but undrawn, as indicated in Note 13: Debt, and $358 million of surety bonds outstanding.

U.S. Government Claims - From time to time, the U.S. Government advises the Company of claims and penalties concerning certain potential disallowed costs. When such findings are presented, the Company and U.S. Government representatives engage in discussions to enable HII to evaluate the merits of these claims as well as to assess the amounts being claimed. The Company does not believe that the outcome of any such matters will have a material effect on its consolidated financial position, results of operations, or cash flows.

16. IMPACTS FROM HURRICANES

In August 2005, the Company's Ingalls operations were significantly impacted by Hurricane Katrina, and the Company's shipyards in Louisiana and Mississippi sustained significant windstorm damage from the hurricane. As a result of the storm, the Company incurred costs to replace or repair destroyed or damaged assets, suffered losses under its contracts, and incurred substantial costs to clean up and recover its operations. At the time of the storm, the Company had an insurance program that provided coverage for, among other things, property damage, business interruption impact on net profitability, and costs associated with clean-up and recovery. The Company recovered a portion of its Hurricane Katrina claim from certain of its participating program insurers in prior periods. In 2013, the Company resolved litigation against its remaining insurer, Factory Mutual Insurance Company ("FM Global"), arising out of a disagreement concerning the coverage of certain losses related to Hurricane Katrina. Under the settlement agreement with FM Global, in the third quarter of 2013 FM Global made a cash payment of $180 million to the Company and the Company agreed to release its claim against FM Global, resulting in a total recovery from the Company's insurers of $677.5 million for its Hurricane Katrina claim. The $180 million was recorded as an insurance recovery gain in operating income in the third quarter of 2013.

In February 2013, the Company submitted a certified claim requesting a final decision on the allowability and allocability of certain post-Katrina depreciation and other Katrina-related expenses and on the apportionment of insurance proceeds. In October 2013, the Company received a Contracting Officer's Final Decision ("COFD") disallowing certain post-Katrina depreciation costs and other Katrina-related expenses, as well as providing direction on the apportionment of Katrina-related insurance recoveries. Impacted by this decision, the Company’s accounting for hurricane insurance related matters resulted in a reduction in operating income of $116 million. The 2013 financial results reflect disallowances as indicated in the COFD.

For the year ended December 31, 2013, the Company’s accounting for hurricane related matters, including the insurance recovery gain of $180 million and the $116 million reduction in operating income related to its contracts with the U.S. Government, resulted in a net favorable impact to operating income of $64 million.

In October 2014, the Company executed a Memorandum of Understanding ("MOU") with the U.S. Navy and U.S. Coast Guard acknowledging the requirements set forth in the COFD. The MOU did not have a material impact on the Company's accounting for hurricane related matters.

In January 2011, the Company, through a predecessor-in-interest, filed suit in Superior Court in California against Aon Risk Insurance Services West, Inc. ("Aon"), which acted as broker to the predecessor-in-interest in connection with the policy with FM Global, seeking damages for breach of contract, professional negligence and negligent misrepresentation, as well as declaratory relief. Those damages include over $200 million in damages unrecovered from FM Global plus costs, legal fees and expenses incurred in the lawsuit against FM Global, as well as interest. In January 2014, the Company amended its complaint to allege fraud and seek punitive damages. No assurances can be provided as to the ultimate outcome of the matter. If, however, the claims are successful, the potential impact to the Company's consolidated financial position, results of operations and cash flows would be favorable.

18. STOCK COMPENSATION PLANS

During the three months endedMarch 31, 2015 and 2014, the Company issued new stock awards as follows:

Restricted Performance Stock Rights - For the three months endedMarch 31, 2015, the Company granted approximately 0.1 million RPSRs at a weighted average share price of $142.41. These rights are subject to cliff vesting on December 31, 2017. For the three months endedMarch 31, 2014, the Company granted approximately 0.2 million RPSRs at a weighted average share price of $98.09. These rights are subject to cliff vesting on December 31, 2016. The RPSRs are subject to the achievement of performance-based targets at the end of the respective vesting periods. Based upon the Company's results measured against such targets, between 0% and 200% of the original stated grants are expected to ultimately vest.

For the three months endedMarch 31, 2015 and 2014, 0.8 million and 0.9 million stock awards, respectively, vested, of which approximately 0.3 million were transferred to the Company from employees in satisfaction of minimum tax withholding obligations for each of the three months endedMarch 31, 2015 and 2014.

Outstanding and exercisable at March 31, 2015	537	$	33.85	1.4	$	56

Compensation Expense

The Company recorded stock-based compensation for the value of awards granted to Company employees and non-employee members of the board of directors for the three months endedMarch 31, 2015 and 2014, of $4 million and $5 million, respectively.

The Company recognized tax benefits for stock-based compensation in the unaudited condensed consolidated statements of operations for the three months endedMarch 31, 2015 and 2014, of $1 million and $2 million, respectively.

Unrecognized Compensation Expense

As of March 31, 2015, the Company had $1 million of unrecognized compensation expense associated with the RSRs granted in 2015 and 2014, which will be recognized over a period of 1.9 years, and $38 million of unrecognized expense associated with the RPSRs granted in 2015, 2014, and 2013, which will be recognized over a weighted average period of 1.4 years.

19. SUBSIDIARY GUARANTORS

Performance of the Company's obligations under the senior notes, including any repurchase obligations resulting from a change of control, is fully and unconditionally guaranteed, jointly and severally, on an unsecured basis, by each of HII's existing and future domestic subsidiaries that guarantees debt under the Credit Facility (the "Subsidiary Guarantors"). See Note 13: Debt. The guarantees rank equally with all other unsecured and unsubordinated indebtedness of the Subsidiary Guarantors. The Subsidiary Guarantors are each directly or indirectly 100% owned by HII.

Set forth below are the unaudited condensed consolidating statements of operations and comprehensive income for the three months endedMarch 31, 2015 and 2014, unaudited condensed consolidating statements of financial position as of March 31, 2015, and December 31, 2014, and the unaudited condensed consolidating statements of cash flows for the three months endedMarch 31, 2015 and 2014, for HII, its aggregated subsidiary guarantors and its aggregated non-guarantor subsidiaries.

Item 2.Management's Discussion and Analysis of Financial Condition and Results of Operations

Overview

Our Business

For more than a century, we have designed, built, overhauled and repaired ships primarily for the U.S. Navy and the U.S. Coast Guard. We conduct business primarily with the U.S. Government, principally the Department of Defense ("DoD"). As prime contractor, principal subcontractor, team member or partner, we participate in many high-priority U.S. defense technology programs. HII is organized into three reportable segments: Ingalls, Newport News, and Other. Through our Ingalls segment, we are the builder of amphibious assault and expeditionary warfare ships for the U.S. Navy, the sole builder of National Security Cutters ("NSC") for the U.S. Coast Guard, and one of only two companies that builds the Navy's current fleet of DDG-51 Arleigh Burke-class destroyers. Through our Newport News segment, we are the nation's sole designer, builder, and refueler of nuclear-powered aircraft carriers, and one of only two companies currently designing and building nuclear-powered submarines for the U.S. Navy. Our Other segment was established in the second quarter of 2014 to account for certain of our non-shipbuilding commercial activities.

The following discussion should be read along with the unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q, as well as our Annual Report on Form 10-K for the year ended December 31, 2014.

Business Environment

In August 2011, the Budget Control Act (the "BCA") reduced the DoD top line budget by $487 billion from fiscal year 2012 through 2021. Additionally, because Congress did not identify savings to reduce the U.S. deficit by up to $1.2 trillion prior to March 1, 2013, budgetary sequestration was implemented under the BCA. Sequestration requires an additional reduction from fiscal year 2012 through 2021 of $500 billion for defense spending and $500 billion for non-defense discretionary spending, including the U.S. Coast Guard. In December 2013, the President signed into law the Bipartisan Budget Act, which provided $63 billion in sequestration relief over two years, split evenly between defense and non-defense programs, and set overall discretionary spending at $1.012 trillion for fiscal year 2014 and $1.013 trillion for fiscal year 2015.

Enactment of the Bipartisan Budget Act enabled the House and Senate Appropriations Committees to agree upon appropriations levels across the 12 Appropriations bills for fiscal year 2015, including Defense Appropriations and Homeland Security, and to subsequently pass the Consolidated and Further Continuing Appropriations Act for Fiscal Year 2015 (the "FY 2015 Consolidated Appropriations Act") in December 2014 and the Homeland Security Appropriations Act for Fiscal Year 2015 in March 2015.

The FY 2015 Consolidated Appropriations Act specifically provided funding for procurement of CVN-79 John F. Kennedy, construction of two SSN-774 Virginia-class submarines, advance procurement for the CVN-73 USS George Washington RCOH, continuation of DDG-51 Arleigh Burke-class destroyer production, and advance procurement for LHA-7 Tripoli. The FY 2015 Consolidated Appropriations Act also provided $1 billion for the procurement of an additional LPD-17 San Antonio-class ship and RDT&E funding for the Ohio Replacement Program. Additionally, the Homeland Security Appropriations Act for Fiscal Year 2015 provided funding for procurement of NSC-8 Midgett. 

While the Fiscal Year 2016 President's Budget Request was delivered to Congress in February 2015, the budget request did not reflect funding reductions required by the Budget Control Act. We cannot predict the impact that the sequestration cuts or other DoD or Homeland Security spending cuts may have on funding for our individual programs.  

Long-term funding for certain programs in which we participate may be reduced, delayed, or cancelled. In addition, defense spending cuts and delays could adversely affect the viability of our suppliers and subcontractors. Our contracts or subcontracts under programs in which we participate may be terminated or adjusted by the U.S. Government or the prime contractor as a result of lack of government funding or reductions or delays in government funding, which would adversely affect our future sales under such programs and could have a material adverse effect on our financial position, results of operations, or cash flows.

24

We expect that the DoD execution of its strategy will require an affordable balance between investments in current missions and investments in new capabilities to meet future challenges. The DoD faces the additional challenge of recapitalizing equipment and rebuilding readiness at a time when the DoD is pursuing modernization of its capabilities, while facing additional major budget cuts that began in 2013. While the Bipartisan Budget Act established new budget caps and provided sequestration relief for fiscal years 2014 and 2015, it is unclear how sequestration could impact programs for 2016 and beyond. Budget Control Act spending caps could have a significant impact on future spending plans for defense and non-defense discretionary programs. Decreases in the proposed funding levels for our programs could negatively impact our financial position, results of operations, or cash flows, including revenues, goodwill, and long-lived assets.

Critical Accounting Policies, Estimates, and Judgments

As discussed in our Annual Report on Form 10-K for the year ended December 31, 2014, we consider the policies relating to the following matters to be critical accounting policies:

• Revenue recognition;

• Purchase accounting and goodwill;

• Litigation, commitments and contingencies;

• Retirement related plans; and

• Workers' compensation.

Most of our revenues are derived from long-term contracts for the production of goods and services provided to the federal government, which are accounted for in conformity with GAAP for construction-type and production-type contracts and federal government contractors. We also have other types of contracts, such as services or commercial arrangements for which revenues are recognized upon delivery or as services are rendered once persuasive evidence of an arrangement exists, the price is fixed or determinable, and collectibility is reasonably assured. Costs related to these contracts are expensed as incurred.

As of March 31, 2015, there had been no other material changes to the above critical accounting policies, estimates, and judgments since December 31, 2014.

Contracts

We generate most of our revenues from long-term U.S. Government contracts for design, production, and support activities. Government contracts typically include the following cost elements: direct material, labor and subcontracting costs, and certain indirect costs including allowable general and administrative expenses. Unless otherwise specified in a contract, costs billed to contracts with the U.S. Government are treated as allowable and allocable costs under the Federal Acquisition Regulations ("FAR") and the U.S. Cost Accounting Standards ("CAS") regulations. Examples of costs incurred by us that are not allowable under the FAR and CAS regulations include certain legal costs, lobbying costs, charitable donations, interest expense and advertising costs.

We monitor our policies and procedures with respect to our contracts on a regular basis to ensure consistent application under similar terms and conditions, as well as compliance with all applicable government regulations. In addition, the Defense Contract Audit Agency ("DCAA") routinely audits the costs we incur that are allocated to contracts with the U.S. Government.

Our long-term contracts typically fall into one of two broad categories:

• Flexibly-Priced Contracts - Includes both cost-type and fixed-price incentive contracts. Cost-type contracts provide for reimbursement of the contractor's allowable costs plus a fee that represents profit. Cost-type contracts generally require that the contractor use its reasonable efforts to accomplish the scope of the work within some specified time and some stated dollar limitation. Fixed-price incentive contracts also provide for reimbursement of the contractor's allowable costs, but are subject to a cost-share limit that affects profitability. Fixed-price incentive contracts effectively become firm fixed-price contracts once the cost-share limit is reached. Approximately 95% and 98% of our revenues for the three months ended

25

March 31, 2015 and 2014, respectively, were generated from flexibly-priced contracts, including certain fixed-price incentive contracts that have exceeded their cost-share limit.

• Firm Fixed-Price Contracts - A firm fixed-price contract is a contract in which the specified scope of work is agreed to for a price that is predetermined by bid or negotiation, and not generally subject to adjustment regardless of costs incurred by the contractor. Time and materials contracts, which specify a fixed hourly rate for each labor hour charged, are considered firm fixed-price contracts. Approximately 5% and 2% of our revenues for the three months endedMarch 31, 2015 and 2014, respectively, were generated from firm fixed-price arrangements.

Contract Fees - Negotiated contract fee structures for both flexibly-priced and firm fixed-price contracts include: fixed fee amounts, cost sharing arrangements to reward or penalize contractors for under or over cost target performance, respectively, positive award fees and negative penalty arrangements. Profit margins may vary materially depending on the negotiated contract fee arrangements, percentage-of-completion of the contract, the achievement of performance objectives, and the stage of performance at which the right to receive fees, particularly under incentive and award fee contracts, is finally determined.

Award Fees - Certain contracts contain award fees based on performance criteria such as cost, schedule, quality and technical performance. Award fees are determined and earned based on an evaluation by the customer of our performance against such negotiated criteria. Fees that we are reasonably assured of collecting and can be reasonably estimated are recorded over the performance period of the contract.

Program Descriptions

For convenience, a brief description of certain programs discussed in this Quarterly Report on Form 10-Q is included in the "Glossary of Programs" in this section.

Financial Accounting Standards ("FAS") and U.S. Cost Accounting Standards ("CAS") Considerations

We calculate our retirement related benefit plan costs under both FAS and CAS. Some of the methodologies and assumptions between FAS and CAS are different, resulting in the FAS/CAS Adjustment.

For example, the discount rate is a significant assumption in determining the value of benefits earned under FAS and CAS. Under FAS, the discount rate is based on yields of high quality bonds, while the CAS discount rate has been an expected rate of return on plan assets assumption. Under the harmonization rules, the CAS discount rate will be based on a methodology more similar to FAS. CAS harmonization is being phased in 25% per year from 2014 through 2017, and the CAS discount rate will move closer toward the FAS rate in the future.

Another difference between FAS expense and CAS cost is the pattern of earnings and expense recognition for gains and losses that arise when our asset and liability experiences differ from our assumptions under each set of requirements. Under FAS, our net gains and losses exceeding the 10% corridor are amortized over the employee's average future service life of approximately 10 years. Under CAS, net gains and losses were amortized over a 15-year period without regard to a corridor approach. Under the harmonization rules, the amortization period for

CAS changed to 10 years for gains and losses experienced beginning in 2013. Both FAS and CAS use a "market-related value" of plan assets approach to calculate the amount of deferred asset gains or losses to be amortized. Under CAS, actual asset gains and losses are systematically spread over five years, subject to certain limitations. We do not use this spreading method for FAS and instead use fair value in determining our FAS expense. Accordingly, FAS expense generally reflects recent gains and losses faster than CAS.

Additionally, CAS cost is only recognized for plans that are not fully funded as defined under CAS. If a plan becomes or ceases to be fully funded due to our asset or liability experience, our CAS cost will change accordingly. We update our estimates of future FAS expense and CAS cost at least annually based on factors such as actual calendar year plan asset returns, actual census data, and other actual and projected experience.

Operating Performance Assessment and Reporting

We manage and assess the performance of our business based on our performance on individual contracts and programs using the financial measures referred to below, with consideration given to the Critical Accounting Policies, Estimates, and Judgments referred to in this section. Our portfolio of long-term contracts is largely flexibly-priced. Therefore, sales tend to fluctuate in concert with costs across our large portfolio of active contracts, with operating income being a critical measure of operating performance. Under FAR rules that govern our business with the U.S. Government, most types of costs are allowable, and we do not focus on individual cost groupings, such as cost of sales or general and administrative expenses, as much as we do on total contract costs, which are a key factor in determining contract operating income. As a result, in evaluating our operating performance, we look primarily at changes in sales and service revenues, as well as operating income, including the effects of significant changes in operating income as a result of changes in contract estimates and the use of the cumulative catch-up method of accounting in accordance with accounting principles generally accepted in the United States of America ("GAAP"). This approach is consistent with the long-term life cycle of our contracts, as management assesses the bidding of each contract by focusing on net sales and operating profit and monitors performance in a similar manner through contract completion. Consequently, our discussion of business segment performance focuses on net sales and operating profit, consistent with our approach for managing our business.

Cost of sales for both product sales and service revenues consist of materials, labor, and subcontracting costs, as well as an allocation of indirect costs for overhead. We manage the type and amount of costs at the contract level, which is the basis for estimating our total costs at completion of our contracts. Unusual fluctuations in operating performance driven by changes in a specific cost element across multiple contracts are described in our analysis.

Sales and Service Revenues

Sales and service revenues consisted of the following:

	Three Months Ended
	March 31				2015 over 2014
($ in millions)	2015		2014		Dollars			Percent
Product sales	$	1,250	$	1,332	$	(82	)	(6	)%
Service revenues	320		262		58			22	%
Sales and service revenues	$	1,570	$	1,594	$	(24	)	(2	)%

Product sales for the three months endedMarch 31, 2015, decreased$82 million, or 6%, compared with the same period in2014. Product sales at our Ingalls segment decreased $76 million for the three months endedMarch 31, 2015, primarily as a result of lower volumes in Amphibious Assault Ships and the Legend-class NSC program, partially offset by higher volumes in Surface Combatants. Newport News product sales decreased $6 million for the

27

three months endedMarch 31, 2015, primarily as a result of lower volumes in Aircraft Carriers, partially offset by higher volumes in Submarines.

Service revenues for the three months endedMarch 31, 2015, increased$58 million, or 22%, compared with the same period in 2014. Service revenues at our Ingalls segment decreased $2 million for the three months endedMarch 31, 2015, as a result of lower volumes in Amphibious Assault Ships services. Service revenues at our Newport News segment increased $20 million for the three months endedMarch 31, 2015, primarily as a result of higher volumes in Fleet Support services. Service revenues at our Other segment for the three months endedMarch 31, 2015, were $40 million, primarily as a result of the acquisition of UPI.

Cost of Sales and Service Revenues

Cost of product sales, cost of service revenues, income from operating investments, net, and general and administrative expenses were as follows:

	Three Months Ended
	March 31						2015 over 2014
($ in millions)	2015			2014			Dollars			Percent
Cost of product sales	$	985		$	1,060		$	(75	)	(7	)%

Cost of sales and service revenues	$	1,414		$	1,435		$	(21	)	(1	)%

Cost of Product Sales

Cost of product sales for the three months endedMarch 31, 2015, decreased$75 million, or 7%, compared with the same period in 2014. Cost of product sales at our Ingalls segment decreased $70 million for the three months endedMarch 31, 2015, primarily due to the lower sales volumes described above. Cost of product sales at our Newport News segment decreased $5 million for the three months endedMarch 31, 2015, primarily as a result of the volume changes described above.

Cost of product sales as a percentage of product sales decreased from 79.6% for the three months endedMarch 31, 2014, to 78.8% for the three months endedMarch 31, 2015, primarily driven by risk retirement onAmphibious Assault Ships and year-to-year variances in contract mix.

Cost of Service Revenues

Cost of service revenues for the three months endedMarch 31, 2015, increased$53 million, or 23%, compared with the same period in 2014. Cost of service revenues at our Ingalls segment decreased $2 million for the three months endedMarch 31, 2015, consistent with the volume changes described above. Cost of service revenues at our Newport News segment increased $17 million for the three months endedMarch 31, 2015, primarily as a result of the higher volumes described above, partially offset by year-to-year variances in contract mix. Cost of service revenues at our Other segment was $38 million for the three months endedMarch 31, 2015, primarily as a result of the acquisition of UPI.

Cost of service revenues as a percentage of service revenues increased from 86.6% for the three months endedMarch 31, 2014, to 87.5% for the three months endedMarch 31, 2015, primarily driven by year-to-year variances in contract mix.

28

Income (Loss) from Operating Investments, Net

The activities of our operating investments are closely aligned with the operations of the segments holding the investments. We therefore record income related to earnings from equity method investments in our operating income.

Income from operating investments, net for the three months ended March 31, 2015, decreased $1 million compared with the same period in 2014, as a result of lower equity income from our Savannah River Nuclear Solutions, LLC investment.

General and Administrative Expenses

In accordance with industry practice and the regulations that govern the cost accounting requirements for government contracts, most general and administrative expenses are considered allowable and allocable costs on government contracts. These costs are allocated to contracts in progress on a systematic basis and contract performance factors include this cost component as an element of cost.

General and administrative expenses for the three months endedMarch 31, 2015, remained constant compared with the same period in 2014. General and administrative costs for 2015 were impacted primarily by the inclusion of UPI, offset by favorable changes in the FAS/CAS Adjustment and other costs.

Operating Income

We consider operating income to be an important measure for evaluating our operating performance and, as is typical in the industry, we define operating income as revenues less the related cost of producing the revenues and general and administrative expenses.

We internally manage our operations by reference to "segment operating income," which is defined as operating income before the FAS/CAS Adjustment and deferred state income taxes, neither of which affects segment performance. Segment operating income is not a recognized measure under GAAP.  When analyzing our operating performance, investors should use segment operating income in addition to, and not as an alternative for, total operating income or any other performance measure presented in accordance with GAAP. It is a metric we use to evaluate our core operating performance.  We believe segment operating income reflects an additional way of viewing aspects of our operations that, when viewed with our GAAP results, provides a more complete understanding of factors and trends affecting our business. We believe the measure is used by investors and is a useful indicator to measure our performance. Because not all companies use identical calculations, our presentation of segment operating income may not be comparable to similarly titled measures of other companies.

The following table reconciles segment operating income to total operating income: 

	Three Months Ended
	March 31				2015 over 2014
($ in millions)	2015		2014		Dollars			Percent
Segment operating income (loss)	$	128	$	137	$	(9	)	(7	)%
FAS/CAS Adjustment	27		22		5			23	%
Deferred state income taxes	1		—		1			—	%
Total operating income (loss)	$	156	$	159	$	(3	)	(2	)%

Segment Operating Income

Segment operating income for the three months endedMarch 31, 2015 was $128 million, a decrease of $9 million compared with the same period in 2014. The decrease was primarily due to UPI performance, as well as lower volumes in Amphibious Assault Ships and the Legend-class NSC program, partially offset by higher volumes in Submarines.

Activity within each segment is discussed in Segment Operating Results below.

29

FAS/CAS Adjustment

The FAS/CAS Adjustment represents the difference between our pension and postretirement plan expense under FAS and under CAS.

The components of the FAS/CAS Adjustment were as follows:

	Three Months Ended
	March 31						2015 over 2014
($ in millions)	2015			2014			Dollars			Percent
FAS expense	$	(42	)	$	(34	)	$	(8	)	(24	)%
CAS cost	69			56			13			23	%
FAS/CAS Adjustment	$	27		$	22		$	5		23	%

The FAS/CAS Adjustment was a net benefit of $27 million and $22 million for the three months endedMarch 31, 2015 and 2014, respectively. The favorable change in the FAS/CAS Adjustment of $5 million for the three months endedMarch 31, 2015, compared to the same period in 2014, was driven by the continued phase-in of Harmonization, favorable 2014 asset returns, and a partial offset due to lower FAS discount rates.

Deferred State Income Taxes

Deferred state income taxes reflect the change in deferred state tax assets and liabilities in the relevant period. These amounts are recorded within operating income, while the current period state income tax expense is charged to contract costs and included in cost of sales and service revenues in segment operating income.

Deferred state income tax benefit for the three months endedMarch 31, 2015, was $1 million, compared to a deferred state tax income benefit of less than $1 million for the same period in 2014. This increase in deferred tax benefit was primarily attributable to changes in pension related adjustments, partially offset by changes in the timing of contract taxable income.

Interest Expense

Interest expense for the three months endedMarch 31, 2015, decreased to $23 million from $27 million for the same period in 2014, primarily as a result of replacing 6.875% senior notes due March 15, 2018, with 5.000% senior notes due December 15, 2021.

Federal Income Taxes

Our effective tax rate on earnings from operations for the three months endedMarch 31, 2015, was 34.6%, compared with 31.8% for the same period in 2014. The higher effective tax rate for the three months endedMarch 31, 2015, was primarily attributable to the non-recurring tax benefit resulting from the release of uncertain tax positions due to expiration of the statute of limitations during the three months endedMarch 31, 2014. Our effective tax rate for the three months endedMarch 31, 2015, differed from the federal statutory rate primarily as a result of the domestic manufacturing deduction. For the three months ended March 31, 2014, our effective tax rate differed from the federal statutory rate primarily as a result of the domestic manufacturing deduction and a non-recurring tax benefit resulting from the release of uncertain tax positions due to expiration of the statute of limitations.

SEGMENT OPERATING RESULTS

Basis of Presentation

We are aligned into three reportable segments: Ingalls, Newport News, and Other. We established the Other segment in the second quarter of 2014 to account for certain of our non-shipbuilding commercial activities.

On January 30, 2015, we completed the acquisition of USG. USG's post-acquisition results of operations, financial position, and cash flows are reported within our Newport News segment. On May 30, 2014, we completed the acquisition of UPI. We report the post-acquisition results of operations, financial position, and cash flows of UPI as

30

part of our Other segment. On January 2, 2014, we completed the acquisition of SN3. SN3's post-acquisition results of operations, financial position, and cash flows are reported within our Newport News segment.

Segment operating results are presented in the following table:

KEY SEGMENT FINANCIAL MEASURES

Sales and Service Revenues

Period-to-period revenues reflect performance under new and ongoing contracts. Changes in sales and service revenues are typically expressed in terms of volume. Unless otherwise described, volume generally refers to increases (or decreases) in reported revenues due to varying production activity levels, delivery rates, or service levels on individual contracts. Volume changes will typically carry a corresponding income change based on the margin rate for a particular contract.

Segment Operating Income

Segment operating income reflects the aggregate performance results of contracts within a segment. Excluded from this measure are certain costs not directly associated with contract performance, including the FAS/CAS Adjustment and deferred state income taxes. Changes in segment operating income are typically expressed in terms of volume, as discussed above, or performance. Performance refers to changes in contract margin rates. These changes typically relate to profit recognition associated with revisions to total estimated costs at completion ("EAC") of the contract that reflect improved (or deteriorated) operating performance on a particular contract. Operating income changes are accounted for on a cumulative to date basis at the time an EAC change is recorded. Segment operating income may also be affected by, among other things, contract performance, the effects of workforce stoppages, the effects of natural disasters such as hurricanes, resolution of disputed items with the customer, recovery of insurance proceeds, and other discrete events. At the completion of a long-term contract, any originally estimated costs not incurred or reserves not fully utilized, such as warranty reserves, could also impact contract earnings. Where such items have occurred and the effects are material, a separate description is provided.

Cumulative Adjustments

For the three months endedMarch 31, 2015 and 2014, favorable and unfavorable cumulative catch-up adjustments were as follows:

	Three Months Ended
	March 31
($ in millions)	2015			2014
Gross favorable adjustments	$	59		$	52
Gross unfavorable adjustments	(4		)	(8		)
Net adjustments	$	55		$	44

For the three months endedMarch 31, 2015, favorable cumulative catch-up adjustments were primarily related to risk retirement on the SSN-774 Virginia-class submarine program, the Legend-class NSC program, and LHA-6USS America. During the same period, none of the unfavorable cumulative catch-up adjustments were individually significant.

For the three months endedMarch 31, 2014, favorable cumulative catch-up adjustments were primarily related to risk retirement on the SSN-774 Virginia-class submarine program, the LPD-17 San Antonio-class program, the Legend-class NSC program, and the construction contract for CVN-78 Gerald R. Ford. During the same period, none of the unfavorable cumulative catch-up adjustments were individually significant.

Sales and Service Revenues

Ingalls revenues for the three months endedMarch 31, 2015, decreased$78 million, or 14%, from the same period in 2014, driven by lower revenues in Amphibious Assault Ships and the Legend-class NSC program, partially offset by higher revenues in Surface Combatants. The decrease in Amphibious Assault Ships revenues was due to lower volumes on LHA-6 USS America, LPD-27 Portland, andLPD-26 John P. Murtha, partially offset by higher volumes on LHA-7 Tripoli. Revenues on the Legend-class NSC program decreased due to lower volume on NSC-4 USCGC Hamilton, partially offset by higher volume on NSC-7 Kimball. Surface Combatants revenues increased due to higher volumes on DDG-119 Delbert D. Black and DDG-113 John Finn, partially offset by lower volumes on the DDG-1000 Zumwalt-class destroyer program.

Segment Operating Income

Ingalls operating income for the three months endedMarch 31, 2015, was $45 million, compared with $43 million for the same period in 2014. The increase was primarily due to risk retirement on LHA-6 USS America, partially offset by the lower volumes described above.

Newport News

	Three Months Ended

Segment operating income (loss)	93			94			(1		)	(1	)%
As a percentage of segment sales	8.8		%	9.0		%

Sales and Service Revenues

Newport News revenues for the three months endedMarch 31, 2015, increased$14 million, or 1%, from the same period in 2014, primarily driven by higher revenues in Submarines and Fleet Support services, partially offset by lower revenues in Aircraft Carriers. Submarines revenues related to the SSN-774 Virginia-class submarine program were higher due to higher volumes on Block IV boats, partially offset by lower volumes on Block II and Block III boats. Higher revenues in Fleet Support services were primarily due to higher volumes associated with CVN-76 USS Ronald Reagan maintenance. Aircraft Carriers revenues decreased due to lower volumes on the execution contract for the CVN-72 USS Abraham Lincoln RCOH and the construction contract for CVN-78 Gerald R. Ford, partially offset by higher volumes on the construction preparation contract for CVN-79 John F. Kennedy.

Segment Operating Income

Newport News operating income for the three months endedMarch 31, 2015, was $93 million, compared with $94 million for the same period in 2014. The decrease was primarily due to lower risk retirement on CVN-78 Gerald R. Ford and lower volumes on Aircraft Carrier RCOH programs, partially offset by higher risk retirement on the SSN-774 Virginia-class submarine program.

Other

Revenues at our Other segment for the three months endedMarch 31, 2015, were $40 million, primarily due to the acquisition of UPI on May 30, 2014. Other operating loss for the three months endedMarch 31, 2015, was $10 million.

BACKLOG

Total backlog as of each of March 31, 2015, and December 31, 2014, was approximately $21 billion. Total backlog includes both funded backlog (firm orders for which funding is contractually obligated by the customer) and unfunded backlog (firm orders for which funding is not currently contractually obligated by the customer). Backlog excludes unexercised contract options and unfunded Indefinite Delivery/Indefinite Quantity orders. For contracts having no stated contract values, backlog includes only the amounts committed by the customer.

The following table presents funded and unfunded backlog by segment as of March 31, 2015, and December 31, 2014: 

	March 31, 2015						December 31, 2014
					Total						Total
($ in millions)	Funded		Unfunded		Backlog		Funded		Unfunded		Backlog
Ingalls	$	6,356	$	1,287	$	7,643	$	5,609	$	1,889	$	7,498

Total backlog	$	14,139	$	7,352	$	21,491	$	11,832	$	9,598	$	21,430

Approximately 28% of the $21 billion total backlog as of December 31, 2014, is expected to be converted into sales in 2015. U.S. Government orders comprised substantially all of the total backlog as of March 31, 2015, and December 31, 2014.

33

Awards

The value of new contract awards during the three months endedMarch 31, 2015, was approximately $1.6 billion. Significant new awards during this period included contracts for construction of NSC-8 Midgett, continued construction for CVN-78 Gerald R. Ford, and advance planning for the CVN-73 USS George Washington RCOH.

LIQUIDITY AND CAPITAL RESOURCES

We endeavor to ensure the most efficient conversion of operating results into cash for deployment in operating our businesses and maximizing stockholder value. We use various financial measures to assist in capital deployment decision making, including net cash provided by operating activities and free cash flow. We believe these measures are useful to investors in assessing our financial performance.

The following table summarizes key components of cash flow provided by (used in) operating activities: 

	Three Months Ended						2015 over
	March 31						2014
($ in millions)	2015			2014			Dollars
Net earnings (loss)	$	87		$	90		$	(3	)

Trade working capital decrease (increase)	(159		)	(365		)	206
Net cash provided by (used in) operating activities	$	(3	)	$	(214	)	$	211

Cash Flows

We discuss below our major operating, investing, and financing activities for the three months endedMarch 31, 2015 and 2014, as classified on our unaudited condensed consolidated statements of cash flows.

Operating Activities

Cash used in operating activities for the three months endedMarch 31, 2015, was $3 million, compared with $214 millionused in operating activities for the same period in 2014. The increase in operating cash flow was primarily due to changes in trade working capital and funding of retiree benefit plans. The change in trade working capital was primarily driven by accounts payable due to timing of payments.

For the three months endedMarch 31, 2015, we made discretionary contributions to our qualified defined benefit pension plans totaling $2 million, compared with $39 million of discretionary contributions for the same period in 2014. For the year ending December 31, 2015, we expect cash contributions to our qualified defined benefit pension plans to be $99 million, all of which will be discretionary.

We expect cash generated from operations in combination with our current cash and cash equivalents, as well as existing credit facilities, to be more than sufficient to service debt, meet contractual obligations, and finance capital expenditures for at least the next 12 months.

Investing Activities

Cash provided by investing activities for the three months endedMarch 31, 2015, was $6 million, compared with $70 millionused in the same period in 2014. The increase in investing cash flow was driven by the 2014 acquisition of SN3 and the sale of the Gulfport Composite Center of Excellence in March 2015. For 2015, we expect our capital expenditures for maintenance and sustainment, excluding discretionary projects, to be approximately 2% of annual revenues.

34

Financing Activities

Cash used in financing activities for the three months endedMarch 31, 2015, was $89 million, compared with $17 millionused in the same period in 2014. The increase was primarily due to an additional $54 million in employee taxes on certain share-based payment arrangements, an additional $19 million of common stock repurchases, and an additional $9 million of cash dividend payments, partially offset by an increase of $11 million in excess tax benefit related to stock compensation.

Free Cash Flow

Free cash flow represents cash provided by (used in) operating activities less capital expenditures. Free cash flow is not a measure recognized under GAAP. Free cash flow has limitations as an analytical tool and should not be considered in isolation from, or as a substitute for, analysis of our results as reported under GAAP. We believe free cash flow is an important measure for our investors because it provides them insight into our current and period-to-period performance and our ability to generate cash from continuing operations. We also use free cash flow as a key operating metric in assessing the performance of our business and as a key performance measure in evaluating management performance and determining incentive compensation. Free cash flow may not be comparable to similarly titled measures of other companies.

The following table reconciles net cash used in operating activities to free cash flow:

	Three Months Ended						2015 over
	March 31						2014
($ in millions)	2015			2014			Dollars
Net cash provided by (used in) operating activities	$	(3	)	$	(214	)	$	211
Less:
Capital expenditures	(20		)	(24		)	4
Free cash flow provided by (used in) operations	$	(23	)	$	(238	)	$	215

Free cash flow for the three months endedMarch 31, 2015, increased$215 million compared with the same period in 2014, primarily due to changes in trade working capital and funding of retiree benefit plans.

Governmental Regulation and Supervision

The U.S. Government has the ability, pursuant to recent regulations relating to contractor business systems, to decrease or withhold contract payments if it determines significant deficiencies exist in one or more such systems. As of March 31, 2015 and 2014, the cumulative amounts of payments withheld by the U.S. Government under our contracts subject to these new regulations were not material to our liquidity or cash flows.

Off-Balance Sheet Arrangements

In the ordinary course of business, we use standby letters of credit issued by commercial banks and surety bonds issued by insurance companies principally to support our self-insured workers' compensation plans. As of March 31, 2015, we had $30 million in standby letters of credit issued but undrawn and $358 million of surety bonds outstanding.

CVN-65 USS Enterprise	Defuel and inactivate the world's first nuclear-powered aircraft carrier, which began in 2013.
CVN-78 Gerald R. Ford-class aircraft carriers	Design and construction for the Ford-class program, which is the aircraft carrier replacement program for CVN-65 USS Enterprise and CVN-68 Nimitz-class aircraft carriers. CVN-78 Gerald R. Ford, the first ship of the Ford-class, is currently under construction. CVN-79 John F. Kennedy is under contract for engineering, advance construction, and purchase of long-lead-time components and material. This category also includes the class' non-recurring engineering. The class is expected to bring improved warfighting capability, quality of life improvements for sailors, and reduced life cycle costs.
DDG-51 Arleigh Burke-class destroyers	Build guided missile destroyers designed for conducting anti-air, anti-submarine, anti-surface and strike operations. The Aegis-equipped DDG-51 Arleigh Burke-class destroyers are the U.S. Navy's primary surface combatant, and have been constructed in variants, allowing technological advances during construction. DDG-113 John Finn and DDG-114 Ralph Johnson are currently under construction. In June 2013, we were awarded a multi-year contract for construction of five additional DDG-51 Arleigh Burke-class destroyers. The first ship of that award, DDG-117 Paul Ignatius, is currently under construction, and construction of DDG-119 Delbert D. Black is scheduled to begin in 2015. DDG-121 (unnamed) was funded in 2015 and is scheduled to begin construction in 2016.

DDG-1000 Zumwalt-class destroyers	Design and build multi-mission surface combatants in conjunction with Bath Iron Works and construct the ships' integrated composite deckhouses, as well as portions of the ships' aft peripheral vertical launch systems. In 2012, we delivered the composite superstructure of DDG-1000 Zumwalt. In 2014, we completed construction and delivered the composite deckhouse of DDG-1001 Michael Monsoor. The delivery of the deckhouse completed our participation in this program as the Navy has decided on a steel deckhouse for the third and final ship of the class.
Energy products and services	Leverage our core competencies in nuclear operations, program management and heavy manufacturing for U.S. Department of Energy ("DoE") and commercial nuclear programs. We also provide a range of services to the energy and oil and gas industries as well as government customers.
Fleet Support services	Fleet Support provides comprehensive life cycle services, including depot maintenance, modernization, repairs, logistics and technical support and planning yard services for naval and commercial vessels. We have ship repair facilities in Newport News, Virginia, and San Diego, California, which are near the U.S. Navy's largest homeports of Norfolk, Virginia and San Diego, respectively. We also perform emergent repair for the U.S. Navy on all classes of ships.
Legend-class National Security Cutter	Design and build the U.S. Coast Guard's National Security Cutters, the largest and most technically advanced class of cutter in the U.S. Coast Guard. The NSC is equipped to carry out maritime homeland security, maritime safety, protection of natural resources, maritime mobility and national defense missions. The plan is for a total of eight ships, of which the first four ships have been delivered. NSC-5 James and NSC-6 Munro are under construction, and, in 2014, we were awarded the construction contract for NSC-7 Kimball and an advance procurement contract for NSC-8 Midgett. We began construction on NSC-7 Kimball in 2015. In 2015, we were awarded the construction contract for the NSC-8 Midgett, which is scheduled to begin construction in 2016.
LHA-6 America-class amphibious assault ships	Design and build amphibious assault ships that provide forward presence and power projection as an integral part of joint, interagency and multinational maritime expeditionary forces. The LHA-6 America-class ships, together with the LHD-1 Wasp-class ships, are the successors to the aging LHA-1 Tarawa-class ships. Three of the original five Tarawa-class ships have been recently decommissioned, and the remainder of the class is scheduled to be decommissioned by 2015. The LHA-6 America-class ships optimize aviation operations and support capabilities. We delivered LHA-6 USS America in April 2014 and LHA-7 Tripoli is currently under construction.
LPD-17 San Antonio-class amphibious transport dock ships	Design and build amphibious transport dock ships, which are warships that embark, transport and land elements of a landing force for a variety of expeditionary warfare missions, and also serve as the secondary aviation platform for Amphibious Readiness Groups. The LPD-17 San Antonio-class is the newest addition to the U.S. Navy's 21st century amphibious assault force, and these ships are a key element of the U.S. Navy's seabase transformation. In October 2013, we delivered LPD-25 USS Somerset, and we are currently constructing LPD-26 John P. Murtha and LPD-27 Portland. The LPD-17 San Antonio-class currently includes a total of 11 ships.
Savannah River Nuclear Solutions, LLC	Participate, as a minority member in a joint venture, in the management and operation of DoE nuclear sites, currently at the Savannah River Site near Aiken, South Carolina, and potentially at other DoE sites. Our joint venture partners at the Savannah River Site include Fluor Federal Services, Inc. and Honeywell International Inc.

SSBN(X) Ohio-class Submarine Replacement Program

Perform, through an agreement with Electric Boat, as design subcontractor for the SSBN(X) Ohio-class replacement boats. The U.S. Navy has committed to designing a replacement class for the SSBN Ohio-class ballistic missile submarines, which were first introduced into service in 1981. We are currently participating in the design effort and our experience and well-qualified workforce position us for a potential role in the construction effort, although no decisions have been made regarding that aspect of the program. The SSBN Ohio-class includes 14 ballistic missile submarines ("SSBN"). The Ohio Replacement Program currently anticipates 12 new ballistic missile submarines over a 15-year period at a cost of approximately $4 billion to $7 billion each. The U.S. Navy has initiated the design process for the new class of submarine, and we have begun design work as a subcontractor to Electric Boat. Congress has delayed the start of the first Ohio replacement submarine by two years and construction is now expected to begin in 2021, with procurement of long-lead-time materials in 2017 and delivery in 2030. The first Ohio-class ballistic missile submarine is expected to be retired in 2027 with an additional submarine being retired each year thereafter. By 2030 the Ohio-class ballistic missile submarine fleet is expected to be ten. The current fiscal environment and uncertainty in defense budgets may cause additional delay to the start of construction or result in a reduction in the number of ships being procured, but we believe the Ohio Replacement Program may represent an opportunity for us in the future.

SSN-774 Virginia-class fast attack submarines

Construct the newest attack submarines as the principal subcontractor to Electric Boat. The SSN-774 Virginia-class is a post-Cold War design tailored to excel in a wide range of warfighting missions, including anti-submarine and surface ship warfare; special operation forces; strike; intelligence, surveillance, and reconnaissance; carrier and expeditionary strike group support; and mine warfare.

Item 3.Quantitative and Qualitative Disclosures about Market Risk

We are exposed to market risk, primarily related to interest rates and foreign currency exchange rates.

Interest Rates - Our financial instruments subject to interest rate risk include floating rate borrowings under our Credit Facility. As of March 31, 2015, we had $395 million in floating rate debt outstanding under our Credit Facility's term loan. Our$650 million revolver remained undrawn as of March 31, 2015. Based on the amounts outstanding under our Credit Facility as of March 31, 2015, an increase of 1% in interest rates would increase the interest expense on our debt by approximately $4 million on an annual basis.

Foreign Currency - We currently have, and in the future may enter into, foreign currency forward contracts to manage foreign currency exchange rate risk related to payments to suppliers denominated in foreign currencies. As of March 31, 2015, the fair values of our outstanding foreign currency forward contracts were not significant.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

The Company's management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of March 31, 2015. Based on that evaluation, the Company's Chief Executive Officer and Chief Financial Officer concluded that, as of March 31, 2015, the Company's disclosure controls and procedures were effective to ensure that information required to be disclosed in reports the Company files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii) accumulated and communicated to management to allow their timely decisions regarding required disclosure.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

BASIS OF PRESENTATION

Principles of Consolidation - The unaudited condensed consolidated financial statements of HII and its subsidiaries have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and the instructions to Form 10-Q promulgated by the Securities and Exchange Commission ("SEC"). All intercompany transactions and balances are eliminated in consolidation. For classification of current assets and liabilities related to its long-term production contracts, the Company uses the duration of these contracts as its operating cycle, which is generally longer than one year.

These unaudited condensed consolidated financial statements include all adjustments of a normal recurring nature considered necessary by management for a fair presentation of the unaudited condensed consolidated financial position, results of operations, and cash flows. These unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2014.

The quarterly information is labeled using a calendar convention; that is, first quarter is consistently labeled as ending on March 31, second quarter as ending on June 30, and third quarter as ending on September 30. It is management's long-standing practice to establish interim closing dates using a "fiscal" calendar, which requires the businesses to close their books on a Friday near these quarter-end dates in order to normalize the potentially disruptive effects of quarterly closings on business processes. The effects of this practice only exist for interim periods within a reporting year.

Accounting Estimates - The preparation of the Company's unaudited condensed consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Estimates have been prepared on the basis of the most current and best available information and actual results could differ materially from those estimates.

The Bipartisan Budget Act of 2013 established budget top lines and provided sequestration relief for 2014 and 2015. Sequestration remains in effect for 2016 through 2021 and could result in significant decreases in DoD spending that could negatively impact the Company's revenues and its estimated recovery of goodwill and other long-lived assets.

Revenue Recognition - The majority of the Company's business is derived from long-term contracts for the construction of naval vessels, production of goods, and provision of services to the federal government, principally the U.S. Navy. In accounting for these contracts, the Company extensively utilizes the cost-to-cost measure of the percentage-of-completion method of accounting, principally based upon total costs incurred. Under this method, sales, including estimated earned fees or profits, are recorded as costs are incurred, generally based on the percentage that total costs incurred bear to total estimated costs at completion. For certain contracts that provide for deliveries of a substantial number of similar units, sales are accounted for using units of delivery as the basis to measure progress toward completion. Certain contracts contain provisions for price redetermination or for cost and/or performance incentives. Such redetermined amounts or incentives are included in sales when the amounts can reasonably be determined and estimated. Amounts representing contract change orders, claims, requests for equitable adjustment, or limitations in funding are included in sales only when they can be reliably estimated and realization is probable. The Company is accounting for one of its contracts under the percentage-of-completion method based on a zero profit margin and will continue such accounting until results can be estimated more precisely. Revenues related to this contract represent less than 1% of the Company's total revenues for the three months endedMarch 31, 2015. The Company estimates profit as the difference between total estimated revenues and total estimated cost of a contract and recognizes that profit over the life of the contract based on progress toward completion. If the Company estimates a contract will result in a loss, the full amount of the estimated loss is recognized against income in the period in which the loss is identified. The Company classifies contract revenues as product sales or service revenues depending upon the predominant attributes of the relevant underlying contracts.

The Company recognizes changes in estimates of contract sales, costs, and profits using the cumulative catch-up method of accounting. This method recognizes in the current period the cumulative effect of the changes on current and prior periods. Accordingly, the effect of the changes on future periods of contract performance is recognized as if the revised estimate had been the original estimate. For the three months endedMarch 31, 2015 and 2014, net cumulative catch-up adjustments increased operating income by $55 million and $44 million, respectively, and increased diluted earnings per share by $0.73 and $0.58, respectively. No individual adjustment was material to the Company's consolidated statements of operations and comprehensive income in any of these periods.

The Company also enters into other types of contracts such as certain services or commercial arrangements. For such contracts not associated with the design, development, manufacture, or modification of complex equipment, revenues are recognized upon delivery or as services are rendered once persuasive evidence of an arrangement exists, the price is fixed or determinable, and collectibility is reasonably assured. Costs related to these contracts are expensed as incurred.

Fair Value of Financial Instruments - Except for long-term debt and available-for-sale securities held in trust, the carrying amounts of the Company's financial instruments recorded at historical cost approximate fair value due to the short-term nature of the instruments and low credit risk associated with the respective counterparties.

The Company maintains multiple rabbi trusts established to fund certain non-qualified pension plans. These trusts consist of available-for-sale investments primarily in marketable securities. The assets are held at fair value, and a significant majority of investments held in the trusts are valued within Level 1 of the fair value hierarchy and no material amounts are valued within Level 3 of the fair value hierarchy. The rabbi trusts were valued at $46 million and $45 million as of March 31, 2015, and December 31, 2014, respectively, and are presented within miscellaneous other assets within the unaudited condensed consolidated statements of financial position.

Description of Business

DESCRIPTION OF BUSINESS

For more than a century, Huntington Ingalls Industries, Inc. ("HII" or the "Company") has been designing, building, overhauling and repairing ships primarily for the U.S. Navy and the U.S. Coast Guard. The Company conducts business primarily with the U.S. Government, principally the Department of Defense ("DoD"). As prime contractor, principal subcontractor, team member or partner, HII participates in many high-priority U.S. defense technology programs. HII is organized into three reportable segments: Ingalls, Newport News, and Other. Through its Ingalls segment, HII is a builder of amphibious assault and expeditionary ships for the U.S. Navy, the sole builder of National Security Cutters for the U.S. Coast Guard, and one of only two companies that builds the Navy's current fleet of DDG-51 Arleigh Burke-class destroyers. Through its Newport News segment, HII is the nation's sole designer, builder and refueler of nuclear-powered aircraft carriers, and one of only two companies currently designing and building nuclear-powered submarines for the U.S. Navy. The Other segment was established in the second quarter of 2014 to account for certain of the Company's non-shipbuilding commercial activities.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

COMMITMENTS AND CONTINGENCIES

Contract Performance Contingencies - Contract profit margins may include estimates of revenues not contractually agreed to between the customer and the Company for matters such as settlements in the process of negotiation, contract changes, claims and requests for equitable adjustment for previously unanticipated contract costs. These estimates are based upon management's best assessment of the underlying causal events and circumstances, and are included in determining contract profit margins to the extent of expected recovery based on contractual entitlements and the probability of successful negotiation with the customer. As of March 31, 2015, the recognized amounts related to claims and requests for equitable adjustment are not material individually or in aggregate.

Guarantees of Performance Obligations - From time to time in the ordinary course of business, HII may enter into joint ventures, teaming and other business arrangements to support the Company's products and services. The Company generally strives to limit its exposure under these arrangements to its investment in the arrangement, or to the extent of obligations under the applicable contract. In some cases, however, HII may be required to guarantee performance of the arrangement's obligations and, in such cases, generally obtains cross-indemnification from the other members of the arrangement. As of March 31, 2015, the Company was not aware of any existing event of default that would require HII to satisfy any of these guarantees.

Environmental Matters -The estimated cost to complete environmental remediation has been accrued where it is probable that the Company will incur such costs in the future to address environmental conditions at currently or formerly owned or leased operating facilities, or at sites where it has been named a Potentially Responsible Party ("PRP") by the Environmental Protection Agency or similarly designated by another environmental agency, and the related costs can be estimated by management. These accruals do not include any litigation costs related to environmental matters, nor do they include amounts recorded as asset retirement obligations. To assess the potential impact on the Company's consolidated financial statements, management estimates the range of reasonably possible remediation costs that could be incurred by the Company, taking into account currently available facts on each site, as well as the current state of technology and prior experience in remediating contaminated sites. These estimates are reviewed periodically and adjusted to reflect changes in facts and technical and legal circumstances. Management estimates that as of March 31, 2015, the probable future cost for environmental remediation is $2 million, which is accrued in other current liabilities. Factors that could result in changes to the Company's estimates include: modification of planned remedial actions, increases or decreases in the estimated time required to remediate, changes to the determination of legally responsible parties, discovery of more extensive contamination than anticipated, changes in laws and regulations affecting remediation requirements, and improvements in remediation technology. Should other PRPs not pay their allocable share of remediation costs, the Company may incur costs exceeding those already estimated and accrued. In addition, there are certain potential remediation sites where the costs of remediation cannot be reasonably estimated. Although management cannot predict whether new information gained as projects progress will materially affect the estimated liability accrued, management does not believe that future remediation expenditures will have a material effect on the Company's consolidated financial position, results of operations or cash flows.

Financial Arrangements - In the ordinary course of business, HII uses standby letters of credit issued by commercial banks and surety bonds issued by insurance companies principally to support the Company's self-insured workers' compensation plans. As of March 31, 2015, the Company had $30 million in standby letters of credit issued but undrawn, as indicated in Note 13: Debt, and $358 million of surety bonds outstanding.

U.S. Government Claims - From time to time, the U.S. Government advises the Company of claims and penalties concerning certain potential disallowed costs. When such findings are presented, the Company and U.S. Government representatives engage in discussions to enable HII to evaluate the merits of these claims as well as to assess the amounts being claimed. The Company does not believe that the outcome of any such matters will have a material effect on its consolidated financial position, results of operations, or cash flows.

Goodwill and Other Purchased Intangible Assets

GOODWILL AND OTHER PURCHASED INTANGIBLE ASSETS

Goodwill

HII performs impairment tests for goodwill as of November 30 of each year and between annual impairment tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the Company's reporting units below their carrying value.

Accumulated goodwill impairment losses as of both March 31, 2015, and December 31, 2014, were $2,802 million. The accumulated goodwill impairment losses for Ingalls as of each of March 31, 2015, and December 31, 2014, were $1,568 million. The accumulated goodwill impairment losses for Newport News as of each of March 31, 2015, and December 31, 2014, were $1,187 million. The accumulated goodwill impairment losses for the Other segment as of each of March 31, 2015, and December 31, 2014, were $47 million.

For the three months ended March 31, 2015, the Company recorded $5 million of goodwill related to its acquisition of USG. For the three months ended March 31, 2014, the Company recorded $42 million of goodwill related to its acquisition of SN3.

For the three months endedMarch 31, 2015, the carrying amounts of goodwill changed as follows:

Purchased Intangible Assets

In connection with the UPI purchase in 2014, the Company recorded $41 million of intangible assets pertaining to existing contracts, trademarks, and trade names to be amortized using the pattern of benefits method over a weighted-average life of 11 years. In connection with the SN3 purchase in 2014, the Company recorded $6 million of intangible assets pertaining to existing contract backlog, trademarks, and trade names to be amortized using the pattern of benefits method over a weighted-average life of five years.

The following table summarizes the Company's aggregate purchased intangible assets, which are primarily program related intangible assets.

Gross carrying amount	$	986		$	986
Accumulated amortization	(446		)	(439		)
Net carrying amount	$	540		$	547

The Company's purchased intangible assets are being amortized on a straight-line basis or a method based on the pattern of benefits. Net intangible assets consist principally of amounts pertaining to nuclear-powered aircraft carrier and submarine program intangibles, with an aggregate weighted-average useful life of 40 years based on the long life cycle of the related programs. Aggregate amortization expense was $7 million and $6 million for the three months endedMarch 31, 2015 and 2014, respectively.

Gulfport

GULFPORT

In September 2013, the Company announced the closure of its Gulfport Composite Center of Excellence in Gulfport, Mississippi, part of the Ingalls reportable segment, which it completed in August 2014. In connection with this closure, the Company incurred total costs of approximately $54 million, consisting of approximately $52 million in accelerated depreciation of fixed assets and $2 million in personnel, facility shutdown, and other related costs. In July 2014, the Company received a letter from the Supervisor of Shipbuilding taking exception to the Company's treatment of the Gulfport closure costs. The Company disagrees with the conclusion reached by the Supervisor of Shipbuilding and is currently evaluating its future course of action. The inability to recover Gulfport closure costs could result in a material effect on the Company's consolidated financial position, results of operations, or cash flows. As of March 31, 2015, and December 31, 2014, $35 million and $37 million, respectively, of accounts receivable was related to Gulfport closure costs. In March 2015, the Company sold the Gulfport Composite Center of Excellence to the Mississippi State Port Authority for a price of $32 million, resulting in a gain on disposition of $9 million, recorded as a reduction to contract costs in accordance with the terms of the Company’s contracts with the U.S. Government.

Restructuring and Related Activities [Abstract]

Avondale

AVONDALE

In 2010, plans were announced to consolidate the Company's Ingalls shipbuilding operations by winding down shipbuilding at the Avondale, Louisiana facility in 2013 after completion of LPD-class ships that were under construction at this facility. In October 2014, the Company ceased shipbuilding construction operations at the Avondale facility. The consolidation is intended to reduce costs, increase efficiency, and address shipbuilding overcapacity.

In connection with and as a result of the decision to wind down shipbuilding at the Avondale facility, the Company began incurring and paying related costs, including, but not limited to, severance expense, relocation expense, and asset write-downs related to the Avondale facilities. Management's current estimate of these expenditures is $287 million. Such costs are expected to be recoverable under existing flexibly-priced contracts or future negotiated contracts in accordance with Federal Acquisition Regulation ("FAR") provisions for the treatment of restructuring and shutdown related costs. The Company is currently in discussions with the U.S. Navy regarding its cost submission to support the recoverability of these costs under the FAR and applicable contracts.

The Defense Contract Audit Agency ("DCAA"), a DoD agency, prepared an initial audit report on the Company's July 2010 cost proposal for restructuring and shutdown related costs of $310 million, which stated that the proposal was not adequately supported for the DCAA to reach a conclusion and questioned approximately $25 million, or 8%, of the costs submitted by the Company. In July 2014, the Company received a letter from the Supervisor of Shipbuilding requesting that the Company revise its restructuring proposal to address certain documentation issues identified by the DCAA in order for the Government to make an adequate evaluation of the restructuring proposal. In August 2014, the Company received a letter from the Supervisor of Shipbuilding proposing a joint meeting regarding the treatment of specific costs included in the restructuring proposal and acknowledging that the allowability and allocability of costs will be determined by the Government in an Advanced Agreement in accordance with FAR. The Company submitted a revised proposal in March 2015 to address the concerns of the DCAA and to reflect a revised estimated total cost of $287 million.

Ultimately, the Company anticipates agreement with the U.S. Navy that is substantially in accordance with management's cost recovery expectations. Accordingly, HII has treated these costs as allowable costs in determining the earnings performance on its contracts in process. The actual restructuring expenses related to the wind down may be greater than the Company's current estimate, and any inability to recover such costs could result in a material effect on the Company's consolidated financial position, results of operations or cash flows.

The Company also evaluated the effect that the wind down of the Avondale facilities might have on the benefit plans in which HII employees participate. HII determined that the impact of a curtailment and other resulting adjustments in these plans was not material to its consolidated financial position, results of operations or cash flows.

As of March 31, 2015, and December 31, 2014, $203 million and $212 million, respectively, of restructuring and shutdown related costs were capitalized in inventoried costs. As of March 31, 2015, and December 31, 2014, $52 million and $48 million, respectively, of accounts receivable was related to restructuring and shutdown related costs. For each of the three months endedMarch 31, 2015 and 2014, the Company expensed $14 million of these costs as part of general and administrative expenses. As of March 31, 2015 and December 31, 2014, there were no accrued liabilities for restructuring and shutdown related costs associated with winding down the Avondale facility and no payments or adjustments were made for the three months endedMarch 31, 2015.

The following table summarizes the changes in the Company's liability for restructuring and shutdown related costs associated with winding down the Avondale facility for the three months endedMarch 31, 2014. As of March 31, 2014, these costs were comprised primarily of employee severance and retention payments, as well as incentive bonuses.

Extraordinary and Unusual Items [Abstract]

Impacts From Hurricanes

IMPACTS FROM HURRICANES

In August 2005, the Company's Ingalls operations were significantly impacted by Hurricane Katrina, and the Company's shipyards in Louisiana and Mississippi sustained significant windstorm damage from the hurricane. As a result of the storm, the Company incurred costs to replace or repair destroyed or damaged assets, suffered losses under its contracts, and incurred substantial costs to clean up and recover its operations. At the time of the storm, the Company had an insurance program that provided coverage for, among other things, property damage, business interruption impact on net profitability, and costs associated with clean-up and recovery. The Company recovered a portion of its Hurricane Katrina claim from certain of its participating program insurers in prior periods. In 2013, the Company resolved litigation against its remaining insurer, Factory Mutual Insurance Company ("FM Global"), arising out of a disagreement concerning the coverage of certain losses related to Hurricane Katrina. Under the settlement agreement with FM Global, in the third quarter of 2013 FM Global made a cash payment of $180 million to the Company and the Company agreed to release its claim against FM Global, resulting in a total recovery from the Company's insurers of $677.5 million for its Hurricane Katrina claim. The $180 million was recorded as an insurance recovery gain in operating income in the third quarter of 2013.

In February 2013, the Company submitted a certified claim requesting a final decision on the allowability and allocability of certain post-Katrina depreciation and other Katrina-related expenses and on the apportionment of insurance proceeds. In October 2013, the Company received a Contracting Officer's Final Decision ("COFD") disallowing certain post-Katrina depreciation costs and other Katrina-related expenses, as well as providing direction on the apportionment of Katrina-related insurance recoveries. Impacted by this decision, the Company’s accounting for hurricane insurance related matters resulted in a reduction in operating income of $116 million. The 2013 financial results reflect disallowances as indicated in the COFD.

For the year ended December 31, 2013, the Company’s accounting for hurricane related matters, including the insurance recovery gain of $180 million and the $116 million reduction in operating income related to its contracts with the U.S. Government, resulted in a net favorable impact to operating income of $64 million.

In October 2014, the Company executed a Memorandum of Understanding ("MOU") with the U.S. Navy and U.S. Coast Guard acknowledging the requirements set forth in the COFD. The MOU did not have a material impact on the Company's accounting for hurricane related matters.

In January 2011, the Company, through a predecessor-in-interest, filed suit in Superior Court in California against Aon Risk Insurance Services West, Inc. ("Aon"), which acted as broker to the predecessor-in-interest in connection with the policy with FM Global, seeking damages for breach of contract, professional negligence and negligent misrepresentation, as well as declaratory relief. Those damages include over $200 million in damages unrecovered from FM Global plus costs, legal fees and expenses incurred in the lawsuit against FM Global, as well as interest. In January 2014, the Company amended its complaint to allege fraud and seek punitive damages. No assurances can be provided as to the ultimate outcome of the matter. If, however, the claims are successful, the potential impact to the Company's consolidated financial position, results of operations and cash flows would be favorable.

Income Taxes

INCOME TAXES

The Company's earnings are principally domestic and its effective tax rates on earnings from operations for the three months endedMarch 31, 2015 and 2014, were 34.6% and 31.8%, respectively. The higher effective tax rate for the three months endedMarch 31, 2015, was primarily attributable to the non-recurring tax benefit resulting from the release of uncertain tax positions due to expiration of the statute of limitations during the three months endedMarch 31, 2014.

For the three months endedMarch 31, 2015, the Company's effective tax rate differed from the federal statutory rate primarily as a result of the domestic manufacturing deduction. For the three months endedMarch 31, 2014, the Company's effective tax rate differed from the federal statutory rate primarily as a result of the domestic manufacturing deduction and a non-recurring tax benefit resulting from the release of uncertain tax positions due to expiration of the statute of limitations.

Deferred state income taxes reflect the change in deferred state assets and liabilities in the relevant period. These amounts are recorded within operating income, while the current period state income tax expense is charged to contract costs and included in cost of sales and service revenues in segment operating income.

Acquisitions [Abstract]

Acquisitions [Text Block]

ACQUISITIONS

On January 30, 2015, the Company acquired, for approximately $6 million in cash, the assets of the Engineering Solutions Division ("ESD") of The Columbia Group. ESD, a leading designer and builder of unmanned underwater vehicles for domestic and international customers, will operate as the Undersea Solutions Group ("USG"). As the U.S. Navy increases employment of unmanned vehicles in both the surface and undersea domains, this acquisition will enhance the Company's ability to compete in these markets. In connection with this acquisition, the Company recorded $5 million of goodwill, all of which was allocated to its Newport News segment, primarily attributed to USG's specialized and skilled employees. See Note 11: Goodwill and Other Purchased Intangible Assets. The assets, liabilities, and results of operations of USG are not material to the Company’s consolidated financial position, results of operations, or cash flows. The Company has not completed the purchase price allocation due to the recent acquisition date and potential adjustments upon finalization of the fair value of the assets acquired and liabilities assumed.

On May 30, 2014, the Company acquired, for approximately $225 million in cash, net of $5 million of cash acquired, UniversalPegasus International Holdings, Inc. ("UPI"), a provider of project management, engineering and construction management services to the oil and gas industry. The acquisition was consistent with the Company's strategy to utilize its engineering and energy related expertise to expand its position in energy infrastructure markets. In connection with this acquisition, the Company recorded $150 million of goodwill, all of which was allocated to its Other segment, primarily related to the value of UPI’s workforce, and $41 million of intangible assets related to contractual relationships and trade names. See Note 11: Goodwill and Other Purchased Intangible Assets. Adjustments to the fair value of assets acquired and liabilities assumed since the acquisition date were not material and were primarily driven by the finalization of the net working capital adjustment and refinement of fair value calculations for certain assets and liabilities. The Company has not completed the purchase price allocation due to potential adjustments upon finalization of the fair value of certain tax assets and liabilities. The assets, liabilities, and results of operations of UPI are not material to the Company’s consolidated financial position, results of operations, or cash flows.

On January 2, 2014, the Company acquired, for approximately $47 million in cash, net of $6 million of cash acquired, The S.M. Stoller Corporation, renamed as Stoller Newport News Nuclear, Inc. ("SN3"), a provider of environmental, nuclear, and technical consulting and engineering services to the Department of Energy, Department of Defense, and private sector. The acquisition was consistent with the Company's strategy to utilize its nuclear and energy related expertise developed through its shipbuilding activities to expand its position in the energy marketplace. In connection with this acquisition, the Company recorded $42 million of goodwill, all of which was allocated to its Newport News segment, primarily attributed to SN3's specialized and skilled employees, and $6 million of intangible assets, primarily related to existing contract backlog and trade names. See Note 11: Goodwill and Other Purchased Intangible Assets. The assets, liabilities, and results of operations of SN3 are not material to the Company’s consolidated financial position, results of operations, or cash flows.

The Company funded each of these acquisitions using cash on hand. The acquisition costs incurred in connection with these acquisitions were not material. The operating results of these businesses have been included in the Company’s consolidated results as of the respective closing dates of the acquisitions. In allocating the purchase price of these businesses, the Company considered the estimated fair value of net tangible and intangible assets acquired, with any excess purchase price recorded as goodwill. The total amount of goodwill resulting from these acquisitions expected to be deductible for tax purposes was $96 million. Pro forma revenues and results of operations have not been provided for these acquisitions as they are not material either individually or in the aggregate.

Investigations, Claims, And Litigation

INVESTIGATIONS, CLAIMS, AND LITIGATION

The Company is involved in legal proceedings before various courts and administrative agencies, and is periodically subject to government examinations, inquiries and investigations. Pursuant to FASB Accounting Standards Codification 450 Contingencies, the Company has accrued for losses associated with investigations, claims and litigation when, and to the extent that, loss amounts related to the investigations, claims and litigation are probable and can be reasonably estimated. The actual losses that might be incurred to resolve such investigations, claims and litigation may be higher or lower than the amounts accrued. For matters where a material loss is probable or reasonably possible and the amount of loss cannot be reasonably estimated, but the Company is able to reasonably estimate a range of possible losses, the Company will disclose such estimated range in these notes. This estimated range is based on information currently available to the Company and involves elements of judgment and significant uncertainties. Any estimated range of possible loss does not represent the Company's maximum possible loss exposure. For matters as to which the Company is not able to reasonably estimate a possible loss or range of loss, the Company will indicate the reasons why it is unable to estimate the possible loss or range of loss. For matters not specifically described in these notes, the Company does not believe, based on information currently available to it, that it is reasonably possible that the liabilities, if any, arising from such investigations, claims and litigation will have a material effect on its consolidated financial position, results of operations or cash flows. The Company has, in certain cases, provided disclosure regarding certain matters for which the Company believes at this time that the likelihood of material loss is remote.

False Claims Act Complaint - In January 2011, the U.S. Department of Justice ("DoJ") first informed the Company through Northrop Grumman of a False Claims Act complaint (the "Complaint") that was filed under seal in the U.S. District Court for the District of Columbia. The redacted copy of the Complaint the Company received alleges that, through largely unspecified fraudulent means, the Company and Northrop Grumman obtained federal funds that were restricted by law for the consequences of Hurricane Katrina, and used those funds to cover costs under certain shipbuilding contracts that were unrelated to Katrina and for which Northrop Grumman and the Company were not entitled to recovery under the contracts. The Complaint seeks monetary damages of at least $835 million, plus penalties, attorneys' fees and other costs of suit. Damages under the False Claims Act may be trebled upon a finding of liability.

In July 2012, the District Court entered an order permitting the Company to disclose certain information not included in the redacted copy of the Complaint received by the Company, including the date the Complaint was filed, the decision of the DoJ to decline intervention in the case, and the principal parties involved in the case. The Complaint was filed on June 2, 2010, by relators Gerald M. Fisher and Donald C. Holmes. In December 2011, the DoJ filed a Notice of Election to Decline Intervention in the case. As of August 29, 2012, Gerald M. Fisher was no longer a relator in or party to this case. In February 2013, the U.S. District Court for the District of Columbia granted the defendants' motion to transfer venue, and the case was transferred to the U.S. District Court for the Southern District of Mississippi. The Company has filed a motion to dismiss the case and a motion to disqualify relator Holmes, and all other matters are stayed pending resolution of the motion to dismiss.

Based upon a review to date of the information available to the Company, the Company believes that it has substantive defenses to the allegations in the Complaint, that the claims as set forth in the Complaint evidence a fundamental lack of understanding of the terms and conditions in the Company's shipbuilding contracts, including the post-Katrina modifications to those contracts, and the manner in which the parties performed in connection with the contracts, and that the claims as set forth in the Complaint lack merit. The Company, therefore, believes that the claims as set forth in the Complaint will not result in a material effect on its consolidated financial position, results of operations or cash flows. The Company intends to defend the matter vigorously, but the Company cannot predict what new or revised claims might be asserted or what information might come to light and can, therefore, give no assurances regarding the ultimate outcome.

U.S. Government Investigations and Claims - Departments and agencies of the U.S. Government have the authority to investigate various transactions and operations of the Company, and the results of such investigations may lead to administrative, civil or criminal proceedings, the ultimate outcome of which could be fines, penalties, repayments or compensatory, treble, or other damages. U.S. Government regulations provide that certain findings against a contractor may also lead to suspension or debarment from future U.S. Government contracts or the loss of export privileges. Any suspension or debarment would have a material effect on the Company because of its reliance on government contracts.

In January 2013, the Company disclosed to the DoD, including the U.S. Navy, and the U.S. Department of Homeland Security, including the U.S. Coast Guard, pursuant to the FAR, that it had initiated an internal investigation regarding whether certain employees at Ingalls mischarged time or misstated progress on Navy and Coast Guard contracts. The Company conducted an internal investigation, led by external counsel, and has taken remedial actions, including the termination of employees in instances where the Company believed grounds for termination existed. The Company is providing information regarding its investigation to the relevant government agencies. The Company agreed with the U.S. Navy and U.S. Coast Guard that they would initially withhold $24 million in payments on existing contracts pending receipt of additional information from the Company's internal investigation. The U.S. Navy has reduced its portion of the withhold from $18.2 million to $4.7 million, while expressing its view that the gross amount of potential mischarging incurred by the Navy will likely not exceed $3.1 million. The U.S. Coast Guard informed the Company in June 2014 that it was provisionally reducing its withhold from $5.8 million to $3.6 million. Based on the results of its internal investigation, the Company estimates that the maximum amount of U.S. Navy and Coast Guard mischarging is approximately $4 million. 

The Company is continuing discussions with its U.S. Government customers regarding the potential release of an additional portion of the withheld funds, but the Company cannot predict whether or when these customers will agree to any additional release of the withhold amount. Depending upon the U.S. Government's assessment of the matters under investigation, the Company could be subject to significant civil penalties, criminal fines, and suspension or debarment from U.S. Government contracting. Although the Company does not currently believe that this matter will have a material effect on its financial condition, results of operations or cash flows, the Company cannot predict what new information might come to light in the future and can therefore give no assurances regarding the ultimate outcome of this matter.

Asbestos Related Claims - HII and its predecessors-in-interest are defendants in a longstanding series of cases that have been and continue to be filed in various jurisdictions around the country, wherein former and current employees and various third parties allege exposure to asbestos containing materials while on or associated with HII premises or while working on vessels constructed or repaired by HII. The cases allege various injuries, including those associated with pleural plaque disease, asbestosis, cancer, mesothelioma and other alleged asbestos related conditions. In some cases, several of HII's former executive officers are also named as defendants. In some instances, partial or full insurance coverage is available to the Company for its liability and that of its former executive officers. Although the Company believes the ultimate resolution of these cases will not have a material effect on its consolidated financial position, results of operations or cash flows, it cannot predict what new or revised claims or litigation might be asserted or what information might come to light and can, therefore, give no assurances regarding the ultimate outcome of asbestos related litigation.

Other Litigation - The Company and its predecessor-in-interest have been in litigation with the Bolivarian Republic of Venezuela (the “Republic”) since 2002 over a contract for the repair, refurbishment and modernization at Ingalls of two foreign-built frigates. The case proceeded towards arbitration, then appeared to settle favorably, but the settlement was overturned in court and the matter returned to litigation. In March 2014, the Company filed an arbitral statement of claim asserting breaches of the contract and $173 million in damages plus substantial interest and litigation expenses. In July 2014, the Republic filed in the arbitration a statement of defense denying all the Company’s allegations and a counterclaim alleging late redelivery of the frigates, unfinished work and breach of warranty and asserting damages of $61 million plus interest. An arbitration hearing was held in January 2015. No assurances can be provided regarding the ultimate outcome of this matter.

The Company is party to various claims and legal proceedings that arise in the ordinary course of business. Although the Company believes that the resolution of any of these various claims and legal proceedings will not have a material effect on its consolidated financial position, results of operations or cash flows, it cannot predict what new or revised claims or litigation might be asserted or what information might come to light and can, therefore, give no assurances regarding the ultimate outcome of these matters.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Accounting Standards Updates

ACCOUNTING STANDARDS UPDATES

On April 7, 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-03, "Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs." The update requires the presentation of capitalized debt issuance costs as a direct reduction of the related debt liability, consistent with the current required presentation of debt discounts. The standard is effective for public entities for annual reporting periods beginning after Dec. 15, 2015, and interim periods within those periods. The Company does not expect the adoption of ASU 2015-03 to have a material impact on the Company's consolidated financial position, results of operations, or cash flows.

On May 28, 2014, the FASB issued the final standard on revenue from contracts with customers. The standard, issued as ASU 2014-09, outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the standard is that "an entity shall recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services." The standard provides a five-step analysis of transactions to determine when and how revenue should be recognized. The five steps are: Identify the contract with the customer; Identify the performance obligations in the contract; Determine the transaction price; Allocate the transaction price to the performance obligations; and Recognize revenue when or as each performance obligation is satisfied. The standard also includes disclosure requirements to provide greater insight into both revenue that has been recognized and revenue that is expected to be recognized in the future from existing contracts, as well as quantitative and qualitative information about significant judgments and changes in the judgments that management made to determine revenue that is recorded. The guidance permits the use of either a retrospective or cumulative effect transition method. As approved, ASU 2014-09 will be effective for public entities for annual reporting periods, including interim reporting periods within those periods, beginning after December 15, 2016 and does not permit early application. On April 1, 2015, the FASB voted to propose a deferral of the effective date of the new revenue recognition standard by one year. Based on the FASB's proposed decision, public entities would apply the new revenue standard to annual reporting periods beginning after December 15, 2017, but early adoption for annual reporting periods beginning after December 31, 2016, would be permitted. The Company is currently evaluating the impact that will result from the implementation of ASU 2014-09 on its financial statements and disclosures, contracting and accounting processes, internal controls, and information technology systems.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Principles of Consolidation

Principles of Consolidation - The unaudited condensed consolidated financial statements of HII and its subsidiaries have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and the instructions to Form 10-Q promulgated by the Securities and Exchange Commission ("SEC"). All intercompany transactions and balances are eliminated in consolidation. For classification of current assets and liabilities related to its long-term production contracts, the Company uses the duration of these contracts as its operating cycle, which is generally longer than one year.

These unaudited condensed consolidated financial statements include all adjustments of a normal recurring nature considered necessary by management for a fair presentation of the unaudited condensed consolidated financial position, results of operations, and cash flows. These unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2014.

Fiscal Period Policy

The quarterly information is labeled using a calendar convention; that is, first quarter is consistently labeled as ending on March 31, second quarter as ending on June 30, and third quarter as ending on September 30. It is management's long-standing practice to establish interim closing dates using a "fiscal" calendar, which requires the businesses to close their books on a Friday near these quarter-end dates in order to normalize the potentially disruptive effects of quarterly closings on business processes. The effects of this practice only exist for interim periods within a reporting year.

Accounting Estimates

Accounting Estimates - The preparation of the Company's unaudited condensed consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Estimates have been prepared on the basis of the most current and best available information and actual results could differ materially from those estimates.

The Bipartisan Budget Act of 2013 established budget top lines and provided sequestration relief for 2014 and 2015. Sequestration remains in effect for 2016 through 2021 and could result in significant decreases in DoD spending that could negatively impact the Company's revenues and its estimated recovery of goodwill and other long-lived assets.

Revenue Recognition Policy

Revenue Recognition - The majority of the Company's business is derived from long-term contracts for the construction of naval vessels, production of goods, and provision of services to the federal government, principally the U.S. Navy. In accounting for these contracts, the Company extensively utilizes the cost-to-cost measure of the percentage-of-completion method of accounting, principally based upon total costs incurred. Under this method, sales, including estimated earned fees or profits, are recorded as costs are incurred, generally based on the percentage that total costs incurred bear to total estimated costs at completion. For certain contracts that provide for deliveries of a substantial number of similar units, sales are accounted for using units of delivery as the basis to measure progress toward completion. Certain contracts contain provisions for price redetermination or for cost and/or performance incentives. Such redetermined amounts or incentives are included in sales when the amounts can reasonably be determined and estimated. Amounts representing contract change orders, claims, requests for equitable adjustment, or limitations in funding are included in sales only when they can be reliably estimated and realization is probable. The Company is accounting for one of its contracts under the percentage-of-completion method based on a zero profit margin and will continue such accounting until results can be estimated more precisely. Revenues related to this contract represent less than 1% of the Company's total revenues for the three months endedMarch 31, 2015. The Company estimates profit as the difference between total estimated revenues and total estimated cost of a contract and recognizes that profit over the life of the contract based on progress toward completion. If the Company estimates a contract will result in a loss, the full amount of the estimated loss is recognized against income in the period in which the loss is identified. The Company classifies contract revenues as product sales or service revenues depending upon the predominant attributes of the relevant underlying contracts.

The Company recognizes changes in estimates of contract sales, costs, and profits using the cumulative catch-up method of accounting. This method recognizes in the current period the cumulative effect of the changes on current and prior periods. Accordingly, the effect of the changes on future periods of contract performance is recognized as if the revised estimate had been the original estimate. For the three months endedMarch 31, 2015 and 2014, net cumulative catch-up adjustments increased operating income by $55 million and $44 million, respectively, and increased diluted earnings per share by $0.73 and $0.58, respectively. No individual adjustment was material to the Company's consolidated statements of operations and comprehensive income in any of these periods.

The Company also enters into other types of contracts such as certain services or commercial arrangements. For such contracts not associated with the design, development, manufacture, or modification of complex equipment, revenues are recognized upon delivery or as services are rendered once persuasive evidence of an arrangement exists, the price is fixed or determinable, and collectibility is reasonably assured. Costs related to these contracts are expensed as incurred.

Fair Value of Financial Instruments

Fair Value of Financial Instruments - Except for long-term debt and available-for-sale securities held in trust, the carrying amounts of the Company's financial instruments recorded at historical cost approximate fair value due to the short-term nature of the instruments and low credit risk associated with the respective counterparties.

The Company maintains multiple rabbi trusts established to fund certain non-qualified pension plans. These trusts consist of available-for-sale investments primarily in marketable securities. The assets are held at fair value, and a significant majority of investments held in the trusts are valued within Level 1 of the fair value hierarchy and no material amounts are valued within Level 3 of the fair value hierarchy. The rabbi trusts were valued at $46 million and $45 million as of March 31, 2015, and December 31, 2014, respectively, and are presented within miscellaneous other assets within the unaudited condensed consolidated statements of financial position.

Credit Facility - In March 2011, the Company entered into the Credit Facility with third-party lenders. The Credit Facility is comprised of a five-year term loan facility of $575 million, which was funded on March 30, 2011, and a revolving credit facility of $650 million, which may be drawn upon during a period of five years from the date of the funding. The revolving credit facility includes a letter of credit subfacility of $350 million and a swingline loan subfacility of $100 million. In November 2013, the Company amended and restated its existing Credit Facility to provide more favorable pricing terms and more flexibility under the Credit Facility’s restricted payment covenants. The term loan and revolving credit facility have a variable interest rate on outstanding borrowings based on the London Interbank Offered Rate ("LIBOR") plus a spread based upon the Company's leverage ratio. As of March 31, 2015, the spread was 1.5% and may vary between 1.5% and 2.5%. The revolving credit facility also has a commitment fee rate on the unutilized balance based on the Company's leverage ratio. As of March 31, 2015, this fee rate was 0.25% and may vary between 0.25% and 0.45%. As of March 31, 2015, approximately $30 million in letters of credit were issued but undrawn, and the remaining $620 million of the revolving credit facility was unutilized.

The term loan facility requires principal payments in three-month intervals from the funding date. Payments were made in aggregate amounts equal to 5% of the original principal balance during each of the first year and the second year, 10% during the third year, and are expected to be made in aggregate amounts equal to 15% during the fourth year, and 65% during the fifth year of which 5% is payable on each of the first three quarterly payment dates during such year, and the balance is payable on the term maturity date.

Senior Notes - In March 2011, the Company issued $600 million aggregate principal amount of 6.875% senior notes due March 15, 2018, and $600 million aggregate principal amount of 7.125% senior notes due March 15, 2021. In December 2014, the Company issued $600 million aggregate principal amount of 5.000% senior notes due December 15, 2021. The net proceeds from the issuance of these senior notes were used to repurchase the Company's 6.875% senior notes due March 15, 2018.

Mississippi Economic Development Revenue Bonds - As of March 31, 2015, the Company had $84 million outstanding under Industrial Revenue Bonds issued by the Mississippi Business Finance Corporation. These bonds accrue interest at a fixed rate of 7.81% and mature in 2024.

Gulf Opportunity Zone Industrial Development Revenue Bonds - As of March 31, 2015, the Company had $21 million outstanding under Gulf Opportunity Zone Industrial Development Revenue Bonds issued by the Mississippi Business Finance Corporation. These bonds accrue interest at a fixed rate of 4.55% and mature in 2028.

The Company's debt arrangements contain customary affirmative and negative covenants, including a maximum total leverage ratio and a minimum interest coverage ratio. The Company was in compliance with all debt covenants during the three months endedMarch 31, 2015.

The estimated fair value of the Company's total long-term debt, including current portions, as of March 31, 2015 and December 31, 2014, was $1,804 million and $1,779 million, respectively. The fair value of the Company's long-term debt was calculated based on either recent trades of the Company's debt instruments in inactive markets or yields available on debt with substantially similar risks, terms and maturities, which fall within Level 2 under the fair value hierarchy.
