Summary of Significant Accounting Policies (Policies)	Mar. 27, 2016
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The information as of March 27, 2016 and for the three months ended March 27, 2016 and March 29, 2015 is unaudited. The condensed consolidated balance sheet as of December 27, 2015 was derived from the Company’s audited consolidated financial statements at that date. In the opinion of management, these unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the interim periods presented. The results have been prepared in accordance with the instructions to Form 10-Q and do not necessarily include all information and footnotes necessary for presentation in accordance with accounting principles generally accepted in the U.S. (“GAAP”). These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes included in the Company’s audited annual consolidated financial statements for the fiscal year ended December 27, 2015, included in the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 11, 2016 (the “Form 10-K”). Interim operating results are not necessarily indicative of operating results expected in subsequent periods or for the year as a whole. As discussed in Note 2 - Discontinued Operations, the amounts related to the first quarter of fiscal 2015 in these condensed consolidated financial statements have been recast to reflect the August 21, 2015 disposition of the Company’s 100% owned subsidiary Herley Industries, Inc. (“Herley”) and certain of Herley’s subsidiaries, including Herley-CTI, Inc., EW Simulation Technology, Ltd. and Stapor Research, Inc. (collectively, the “Herley Entities”) as discontinued operations.
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its 100% owned subsidiaries for which all inter-company transactions have been eliminated in consolidation.
Fiscal Year	Fiscal Year The Company has a 52/53 week fiscal year ending on the last Sunday of the calendar year, with interim fiscal periods ending on the last Sunday of each calendar quarter. The three month periods ended March 27, 2016 and March 29, 2015 consisted of 13-week periods. There are 52 calendar weeks in the fiscal years ending on December 25, 2016 and December 27, 2015.
Accounting Estimates	Accounting Estimates There have been no significant changes in the Company’s accounting estimates for the three months ended March 27, 2016 as compared to the accounting estimates described in the Form 10-K.
Accounting Standards Updates	Accounting Standards Updates In April 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updated (“ASU”) 2016-10 (“ASU 2016-10”), Revenue from Contracts with Customers, Identifying Performance Obligations and Licensing. ASU 2016-10 provides additional guidance on identifying performance obligations and clarifies the implementation guidance on licensing. In March 2016, the FASB issued ASU 2016-08 (“ASU 2016-08”), Revenue from Contracts with Customers, Principal versus Agent Considerations. ASU 2016-08 clarifies the implementation guidance and illustrations in the new revenue standard. In August 2015, the FASB issued ASU 2015-14 (“ASU 2015-14”), Revenue from Contracts with Customers, Deferral of the Effective Date that deferred the effective date of ASU 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers. Pursuant to ASU 2015-14, public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The FASB issued ASU 2014-09 in May 2014. ASU 2014-09 affects any entity using GAAP that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (e.g., insurance contracts or lease contracts). ASU 2014-09 will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. ASU 2014-09 also supersedes some cost guidance included in FASB Accounting Standards Codification (“ASC”) Subtopic 605-35, Revenue Recognition—Construction-Type and Production-Type Contracts. The guidance permits companies to either apply the requirements retrospectively to all prior periods presented or apply the requirements in the year of adoption, through a cumulative adjustment. The Company has not yet selected a transition method nor has it determined the impact of adoption on its condensed consolidated financial statements. In March 2016, the FASB issued ASU 2016-09 (“ASU 2016-09”), Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies several aspects of the accounting for employee share-based payments, including accounting for income taxes, forfeitures, statutory tax withholding requirements, and classification on the statement of cash flows. The amendments in this ASU are effective for annual periods beginning after December 15, 2016. Early adoption is permitted. The Company has not determined the impact of adoption on its condensed consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 (“ASU 2016-02”), Leases. ASU 2016-02 requires that lessees recognize assets and liabilities for the rights and obligations for leases with a lease term of more than one year. The amendments in this ASU are effective for annual periods ending after December 15, 2018. Early adoption is permitted. The Company has not determined the impact of adoption on its condensed consolidated financial statements. In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. The ASU eliminates the current requirement for organizations to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, organizations will be required to classify all deferred tax assets and liabilities as noncurrent. The amendments apply to all organizations that present a classified balance sheet. For public companies, the amendments are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The FASB also decided to permit earlier application by all entities as of the beginning of any interim or annual reporting period. The amendment provides the reporting entity with an option to apply the amendment prospectively, or retrospectively to all prior periods presented in the financial statements. The Company adopted ASU 2015-17 prospectively for the fiscal year ended December 27, 2015. In August 2015, the FASB issued ASU 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting. ASU 2015-15 supplements the requirements of ASU 2015-03 by allowing an entity to defer and present debt issuance costs related to a line of credit arrangement as an asset and subsequently amortize the deferred costs ratably over the term of the line of credit arrangement. The Company adopted ASU 2015-15 for the fiscal year ended December 27, 2015. In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in ASU 2015-03. The amendments in this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2015 and interim periods within those fiscal years and early adoption of the amendments is permitted for financial statements that have not been previously issued and should be applied on a retrospective basis. The Company adopted ASU 2015-03 for the fiscal year ended December 27, 2015 In January 2015, the FASB issued ASU 2015-01 (“ASU 2015-01”), Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. ASU 2015-01 eliminates from GAAP the concept of extraordinary items. Subtopic 225-20, Income Statement - Extraordinary and Unusual Items, required that an entity separately classify, present, and disclose extraordinary events and transactions. Presently, an event or transaction is presumed to be an ordinary and usual activity of the reporting entity unless evidence clearly supports its classification as an extraordinary item. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The Company adopted this standard in the quarter ended March 27, 2016, which did not have a material impact on its condensed consolidated financial statements. In August 2014, the FASB issued ASU 2014-15 (“ASU 2014-15”), Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. Under GAAP, financial statements are prepared under the presumption that the reporting organization will continue to operate as a going concern, except in limited circumstances. Financial reporting under this presumption is commonly referred to as the going concern basis of accounting. The going concern basis of accounting is critical to financial reporting because it establishes the fundamental basis for measuring and classifying assets and liabilities. Currently, GAAP lacks guidance about management’s responsibility to evaluate whether there is substantial doubt about the organization’s ability to continue as a going concern or to provide related footnote disclosures. ASU 2014-15 provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations today in the financial statement footnotes. The amendments are effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter. Early application is permitted for annual or interim reporting periods for which the financial statements have not previously been issued. The Company does not believe that the adoption of this guidance will have a material impact on its condensed consolidated financial statements. There have been no changes in the Company’s significant accounting policies, other than the adoption of ASU 2015-01, for the three months ended March 27, 2016 as compared to the significant accounting policies described in the Form 10-K.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying amounts and the related estimated fair values of the Company’s long-term debt financial instruments not measured at fair value on a recurring basis at March 27, 2016 and December 27, 2015 are presented in Note 8. The carrying value of all other financial instruments, including cash equivalents, accounts receivable, accounts payable, accrued expenses, billings in excess of cost and earnings on uncompleted contracts, income taxes payable and short-term debt, approximated their estimated fair values at March 27, 2016 and December 27, 2015 due to the short-term nature of these instruments.
Net Income (Loss) Per Common Share	Net Loss Per Common Share The Company calculates net loss per share in accordance with FASB ASC Topic 260, Earnings per Share (Topic 260). Under Topic 260, basic net loss per common share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the reporting period. Diluted net loss per common share reflects the effects of potentially dilutive securities.
