Summary of Significant Accounting Policies [Abstract]

ConsolidationPolicyTextBlock

A. Principles of Consolidation

The consolidated financial statements include the accounts of the Corporation and its majority-owned subsidiaries. All intercompany transactions and accounts have been eliminated.

UseOfEstimates

B. Use of Estimates

The financial statements of the Corporation have been prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP), which requires management to make estimates and judgments that affect the reported amount of assets, liabilities, revenue, and expenses and disclosure of contingent assets and liabilities in the accompanying financial statements. The most significant of these estimates includes the estimate of costs to complete long-term contracts under the percentage-of-completion accounting methods, the estimate of useful lives for property, plant, and equipment, cash flow estimates used for testing the recoverability of assets, pension plan and postretirement obligation assumptions, estimates for inventory obsolescence, estimates for the valuation and useful lives of intangible assets, warranty reserves, legal reserves, and the estimate of future environmental costs. Actual results may differ from these estimates.

RevenueRecognitionPolicyTextBlock

C. Revenue Recognition

The realization of revenue refers to the timing of its recognition in the accounts of the Corporation and is generally considered realized or realizable and earned when the earnings process is substantially complete and all of the following criteria are met: 1) persuasive evidence of an arrangement exists; 2) delivery has occurred or services have been rendered; 3) the Corporation's price to its customer is fixed or determinable; and 4) collectability is reasonably assured.

TheCorporation records sales and related profits on production and service type contracts as units are shipped and title and risk of loss have transferred or as services are rendered, net of estimated returns and allowances. Sales and estimated profits under certain long-term contracts are recognized primarily under the units-of-delivery or cost-to-costpercentage-of-completion methods of accounting. Under the cost-to-cost percentage-of-completion method of accounting, profits are recorded pro rata, based upon current estimates of direct and indirect costs to complete such contracts. Under the units-of-delivery method of accounting, revenue is recognized as units are delivered to the customer. In addition, the Corporation also records sales under certain long-term government fixed price contracts upon achievement of performance milestones as specified in the related contracts.Changes in estimates of contract sales, costs, and profits are recognized 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. The effect of the changes on future periods of contract performance is recognized as if the revised estimate had been the original estimate. A significant change in an estimate on one or more contracts could have a material effect on the Corporation's consolidated financial position, results of operations, or cash flows.In 2012, the Corporation incurredunanticipated additional costs of $23.7 million on its long-term contract with Westinghouse for disassembly, inspection, and preparation for shipment costs related to the reactor coolant pumps (RCPs) that the Corporation is supplying for the AP1000 nuclear power plants in China. In addition, the Corporation recorded a cumulative catch up benefit of $14.2 million related to a change in estimate on its technology transfer contract on the AP1000 nuclear program. In 2011, the Corporation incurred unanticipated additional costs to address a localized heating issue in the RCPs. The additional costs increased the estimated costs at completion which decreased consolidated operating income by$9.7 million. In 2010, the Corporation incurred various changes in its cost estimates for the AP1000 nuclear power plants which decreased operating income by $11.4 million. There were no other individual significant changes in estimated contract costs at completion.

Losses on contracts are provided for in the period in which the losses become determinable and the excess of billings over cost and estimated earnings on long-term contracts is included in deferred revenue.

CashAndCashEquivalentsPolicyTextBlock

D. Cash and Cash Equivalents

Cash equivalents consist of money market funds and commercial paper that are readily convertible into cash, all with original maturity dates of three months or less.

InventoryPolicyTextBlock

E. Inventory

Inventories are stated at lower of production cost (principally average cost) or market. Production costs are comprised of direct material and labor and applicable manufacturing overhead.

GovernmentContractorsContractsInProgressPolicyPolicyTextBlock

F. Progress Payments

Certain long-term contracts provide for interim billings as costs are incurred on the respective contracts. Pursuant to contract provisions, agencies of the U.S. Government and other customers are granted title or a secured interest for materials and work-in-process included in inventory to the extent progress payments are received. Accordingly, these receipts have been reported as a reduction of unbilled receivables and inventories, as presented in Notes 5 and 6 to the Consolidated Financial Statements.

PropertyPlantAndEquipmentPolicyTextBlock

G. Property, Plant, and Equipment

Property, plant, and equipment are carried at cost less accumulated depreciation. Major renewals and betterments are capitalized, while maintenance and repairs that do not improve or extend the life of the asset are expensed in the period they are incurred. Depreciation is computed using the straight-line method based upon the estimated useful lives of the respective assets.

Average useful lives for property, plant, and equipment are as follows:

Buildings and improvements	5	to	40	years
Machinery, equipment, and other	3	to	15	years

GoodwillAndIntangibleAssetsIntangibleAssetsPolicy

H. IntangibleAssets

Intangible assets are generally the result of acquisitions and consist primarily of purchased technology, customer related intangibles, trademarks and service marks, and technology licenses. Definite lived intangible assets are amortized on a straight-line basis over their estimated useful lives, which range from 1 to 20 years, while indefinite lived intangible assets are not amortized. Indefinite lived intangible assets are reviewed for impairment annually based on the discounted future cash flows. See Note 9 to the Consolidated Financial Statements for further information on other intangible assets.

ImpairmentOrDisposalOfLongLivedAssetsPolicyTextBlock

I. Impairment of Long-LivedAssets

The Corporation reviews the recoverability of all long-lived assets, including the related useful lives, whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset might not be recoverable. If required, the Corporation compares the estimated fair value determined by either the undiscounted future net cash flows or appraised value to the related asset's carrying value to determine whether there has been an impairment. If an asset is considered impaired, the asset is written down to fair value, which is based either on discounted cash flows or appraised values in the period the impairment becomes known. In 2012, the Corporation recognized an impairment of $5.0 million in connection with its 2012 restructuring plan, a component of which was exiting a facility. In 2011, the Corporation recognized a $0.2 million impairment related to one facility where it was determined that the carrying value exceeded the estimated fair value.In 2010, the Corporation recognized a $1.5 million impairment related to two facilities where it was determined that their carrying value exceeded their estimated fair value.

Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]

J. Goodwill

Goodwill results from business acquisitions. The Corporation accounts for business acquisitions by allocating the purchase price to the tangible and intangible assets acquired and liabilities assumed. Assets acquired and liabilities assumed are recorded at their fair values, and the excess of the purchase price over the amounts allocated is recorded as goodwill. The recoverability of goodwill is subject to an annual impairment test or whenever an event occurs or circumstances change that would more likely than not result in an impairment. The impairment test is based on the estimated fair value of the underlying businesses. The Corporation's goodwill impairment test is performed as of October 31 of each year. See Note 8 to the Consolidated Financial Statements for further information on goodwill.

PrecontractCostsPolicyTextBlock

K. Pre-Contract Costs

The Corporation, from time to time, incurs costs to begin fulfilling the statement of work under a specific anticipated contract that has yet to be obtained from a customer. If it is determined that the recoveries of these costs are probable, the costs will be capitalized, excluding any start-up costs which are expensed as incurred. When circumstances change and the contract is no longer deemed probable, the capitalized costs will be recognized in earnings. There were no costs written off in 2012, 2011, and 2010. Capitalized pre-contract costs were $3.0 million and $0.3 million at December 31, 2012 and 2011, respectively.

FairValueOfFinancialInstrumentsPolicy

L. Fair Value of Financial Instruments

Accounting guidance requires certain disclosures regarding the fair value of financial instruments. Due to the short maturities of cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses, the net book value of these financial instruments is deemed to approximate fair value. See Notes 10 and 14to the Consolidated Financial Statements for further information.

ResearchAndDevelopmentExpensePolicy

M. Research and Development

The Corporation funds research and development programs for commercial products and independent research and development and bid and proposal work related to government contracts. Development costs include engineering and field support for new customer requirements. Corporation-sponsored research and development costs are expensed as incurred.

Research and development costs associated with customer-sponsored programs are capitalized to inventory and are recorded in cost of sales when products are delivered or services performed. Funds received under shared development contracts are a reduction of the total development expenditures under the shared contract and are shown net as research and development costs.

EnvironmentalCostsPolicy

N. Environmental Costs

The Corporation establishes a reserve for a potential environmental remediation liability on a site by site basis when it concludes that a determination of legal liability is probable and the amount of the liability can be reasonably estimated based on current law and existing technologies. Such amounts, if quantifiable, reflect the Corporation's estimate of the amount of that liability. If only a range of potential liability can be estimated and no amount within the range is more probable than another, a reserve will be established at the low end of that range. At sites involving multiple parties, the Corporation accrues environmental liabilities based upon its expected share of the liability, taking into account the financial viability of other jointly liable partners. Such reserves are adjusted as assessment and remediation efforts progress or as additional information becomes available. Approximately 26% of the Corporation's environmental reserves as of December 31, 2012, represent the current value of anticipated remediation costs and are not discounted primarily due to the uncertainty of timing of expenditures. The remaining environmental reserves are discounted to reflect the time value of money since the amount and timing of cash payments for the liability are reliably determinable. All environmental reserves exclude any potential recovery from insurance carriers or third-party legal actions. See Note 17to the Consolidated Financial Statements for additional information.

ShareBasedCompensationOptionAndIncentivePlansPolicy

O. Accounting for Share-Based Payments

The Corporation follows the fair value based method of accounting for share-based employee compensation, which requires the Corporation to expense all share-based employee compensation. Share-based employee compensation is primarily a non-cash expense since the Corporation settles these obligations by issuing the shares of Curtiss-Wright Corporation instead of settling such obligations with cash payments.

Compensation expense for all non-qualified share options, performance shares, performance-based restricted shares, time-based restricted stock, and performance-based restricted stock units is recognized on a graded schedule over the requisite service period for the entire award based on the grant date fair value.

EarningsPerSharePolicyTextBlock

P.Earnings Per Share

The Corporation is required to report both basic earnings per share (EPS), based on the weighted-average number of Common shares outstanding, and diluted earnings per share, based on the basic EPS adjusted for all potentially dilutive shares issuable. The calculation of EPS is disclosed in Note 15 to the Consolidated Financial Statements.

IncomeTaxPolicyTextBlock

Q. Income Taxes

The Corporation accounts for income taxes using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. The effect on deferred tax assets and liabilities of a change in tax laws is recognized in the results of operations in the period the new laws are enacted. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets unless it is more likely than not that such assets will be realized.

The Corporation records amounts related to uncertain income tax positions by 1) prescribing a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements and 2) the measurement of the income tax benefits recognized from such positions. The Corporation's accounting policy is to classify uncertain income tax positions that are not expected to be resolved in one year as a non-current income tax liability and to classify interest and penalties as a component of Interest expense and General and administrative expenses, respectively. See Note 13to the Consolidated Financial Statements for further information.

ForeignCurrencyTransactionsAndTranslationsPolicyTextBlock

R. Foreign Currency

For operations outside the United States of America that prepare financial statements in currencies other than the U.S. dollar, the Corporation translates assets and liabilities at period-end exchange rates and income statement amounts using weighted-average exchange rates for the period. The cumulative effect of translation adjustments is presented as a component of accumulated other comprehensive income within stockholders' equity. This balance is affected by foreign currency exchange rate fluctuations and by the acquisition of foreign entities. Gains and (losses) from foreign currency transactions are included in General and administrative expenseswithin the results of operations, which amounted to $(2.3) million, $(0.8)million, and $(4.2)million for the years ended December 31, 2012, 2011, and 2010, respectively.

DerivativesPolicyTextBlock

S. Derivatives

Forward Foreign Exchange and Currency Option Contracts

The Corporation uses financial instruments, such as forward exchange and currency option contracts, to hedge a portion of existing and anticipated foreign currency denominated transactions. The purpose of the Corporation's foreign currency risk management program is to reduce volatility in earnings caused by exchange rate fluctuations. All of the derivative financial instruments are recorded at fair value based upon quoted market prices for comparable instruments, with the gain or loss on these transactions recorded into earnings in the period in which they occur. These gains and (losses) are classified as General and administrative expenses in the Consolidated Statements of Earnings and amounted to$ 0.9 million,$ (0.7) million,and $ 3.1million for the years ended December 31, 2012, 2011 and 2010, respectively. The Corporation does not use derivative financial instruments for trading or speculative purposes.

Interest Rate Risks and Related Strategies

The Corporation's primary interest rate exposure results from changes in U.S. dollar interest rates. The Corporation's policy is to manage interest cost using a mix of fixed and variable rate debt. The Corporation periodically uses interest rate swaps to manage such exposures. Under these interest rate swaps, the Corporation exchanges, at specified intervals, the difference between fixed and floating interest amounts calculated by reference to an agreed-upon notional principal amount.

For interest rate swaps designated as fair value hedges (i.e., hedges against the exposure to changes in the fair value of an asset or a liability or an identified portion thereof that is attributable to a particular risk), changes in the fair value of the interest rate swaps offset changes in the fair value of the fixed rate debt due to changes in market interest rates.

Fair Value Of Financial Measurements [Policy Text Block]

Fair Value Measurement: Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in United States of America generally accepted accounting principles (U.S. GAAP) and International Financial Reporting Standards (IFRS)

In May 2011, new guidance was issued that amends the current fair value measurement and disclosure guidance to increase transparency around valuation inputs and investment categorization. The new guidance does not extend the use of fair value accounting, but provides guidance on how it should be applied where its use is already required or permitted by other standards within U.S. GAAP or IFRS. The new guidance is effective for annual and interim reporting periods beginning on or after December 15, 2011 and is to be adopted prospectively as early adoption is not permitted. The adoption of this guidance did not have an impact on the Corporation's results of operations or financial condition.

Other Comprehensive Income [Policy Text Block]

Other Comprehensive Income: Presentation of Comprehensive Income

In June 2011, new guidance was issued that amends the current comprehensive income guidance. The new guidance allows the option of presenting the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single or continuous statement of comprehensive income or in two separate but consecutive statements. The amendments in this update do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. The new guidance is to be applied retrospectively and is effective for fiscal years, and interim periods, beginning after December 15, 2011. In December 2011, the Financial Accounting Standards Board (FASB) issued authoritative guidance to defer the effective date for those aspects of the guidance relating to the presentation of reclassification adjustments out of accumulated other comprehensive income. The adoption of this new guidance did not have an impact on the Corporation's consolidated financial position, results of operations or cash flows as it only requires a change in the format of the current presentation of other comprehensive income.

Goodwill Testing For Impairment [Policy Text Block]

Intangibles—Goodwill and Other: Testing Goodwill for Impairment

In September 2011, new guidance was issued that amends the current testing requirements of goodwill for impairment purposes. The new guidance gives companies the option to perform a qualitative assessment to first assess whether the fair value of a reporting unit is less than its carrying amount. If an entity determines it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. The new guidance is to be applied prospectively effective for annual and interim goodwill impairment tests beginning after December 15, 2011, with early adoption permitted. The adoption of this standard did not have an impact on the Corporation's results of operations or financial condition.

New Accounting Pronouncement Or Change In Accounting Principle [Policy Text Block]

Standards Issued But Not Yet Effective

In February 2013, new guidance was issued that amends the current comprehensive income guidance. The new guidance requires entities to disclose the effect of each item that was reclassified in its entirety out of accumulated other comprehensive income and into net income on each affected net income line item. For reclassification items that are not reclassified in their entirety into net income a cross reference to other required disclosures is required. The adoption of this new guidance is to be applied prospectively, and for annual reporting periods beginning after December 15, 2012 and interim periods within those years. The adoption of this new guidance will not have an impact on the Corporation's consolidated financial position, results of operations or cash flows.
