Summary_Of_Significant_Account

Summary Of Significant Accounting Policies	3 Months Ended

Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Consolidation and Classification. The unaudited Consolidated Financial Statements include the accounts of General Dynamics Corporation and our wholly owned and majority-owned subsidiaries. We eliminate all inter-company balances and transactions in the unaudited Consolidated Financial Statements.
	Consistent with defense industry practice, we classify assets and liabilities related to long-term production contracts as current, even though some of these amounts may not be realized within one year. In addition, some prior-year amounts have been reclassified among financial statement accounts to conform to the current-year presentation.
	Interim Financial Statements. The unaudited Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. These rules and regulations permit some of the information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) to be condensed or omitted.
	Our fiscal quarters are 13 weeks in length. Because our fiscal year ends on December 31, the number of days in our first and fourth quarters varies slightly from year to year. Operating results for the three-month period ended April 5, 2015, are not necessarily indicative of the results that may be expected for the year ending December 31, 2015.
	The unaudited Consolidated Financial Statements contain all adjustments that are of a normal recurring nature necessary for a fair presentation of our results of operations and financial condition for the three-month periods ended April 5, 2015, and March 30, 2014.
	These unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2014.
	Revenue Recognition. We account for revenues and earnings using the percentage-of-completion method. Under this method, contract costs and revenues are recognized as the work progresses, either as the products are produced or as services are rendered. We estimate the profit on a contract as the difference between the total estimated revenue and costs to complete a contract and recognize that profit over the life of the contract. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we recognize the loss in the quarter it is identified.
	We review and update our contract-related estimates regularly. We recognize changes in estimated profit on contracts under the reallocation method. Under the reallocation method, the impact of a revision in estimate is recognized prospectively over the remaining contract term. The net increase in our operating earnings (and on a per-share basis) from the impact of revisions in contract estimates totaled favorable changes of $63 ($0.12) and $38 ($0.07) for the three-month periods ended April 5, 2015, and March 30, 2014, respectively. No revisions on any one contract were material to our unaudited Consolidated Financial Statements in the first quarter of 2015 or 2014.
	In the second quarter of 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers. ASU 2014-09 prescribes a single, common revenue standard that replaces most existing revenue recognition guidance in GAAP. The standard outlines a five-step model, whereby revenue is recognized as performance obligations within a contract are satisfied. The standard also requires new, expanded disclosures regarding revenue recognition.
	For public companies, ASU 2014-09 is effective in the first quarter of 2017. On April 1, 2015, the FASB proposed a one-year deferral of the standard's effective date, while permitting entities to still adopt one year earlier on the original effective date. A final determination will be made after a public comment period. The standard permits the use of either the retrospective or cumulative effect transition method. We have not yet selected a transition date or method nor have we determined the effect of the standard on our consolidated financial statements as the standard continues to undergo changes.
	The required adoption of the ASU will preclude our use of the reallocation method of recognizing revisions in estimated profit on contracts discussed above. As changes in estimated profit will be recognized in the period they are identified (cumulative catch-up method), rather than prospectively over the remaining contract term, we expect that the impact of revisions of contract estimates may be larger and potentially more variable from period to period. Anticipated losses on contracts will continue to be recognized in the quarter they are identified.
	Discontinued Operations. We completed the sale of our axle business in the Combat Systems group in January 2015. The financial statements have been restated to reflect the results of operations of this business in discontinued operations.
	Subsequent Events. We have evaluated material events and transactions that have occurred after April 5, 2015, and concluded that none have occurred that require adjustment to or disclosure in the unaudited Consolidated Financial Statements.

Goodwill and Intangible Assets Disclosure [Abstract]
Acquisitions, Intangible Assets And Goodwill	ACQUISITIONS, INTANGIBLE ASSETS AND GOODWILL
	We did not acquire any businesses in the first quarter of 2015. In 2014, our Information Systems and Technology group acquired a provider of IT support to U.S. special operations forces.
	The operating results of this acquisition have been included with our reported results since the closing date. The purchase price of this acquisition has been allocated to the estimated fair value of net tangible and intangible assets acquired, with any excess purchase price recorded as goodwill.
	The changes in the carrying amount of goodwill by reporting unit for the three months ended
	April 5, 2015, were as follows:
		Aerospace			Combat Systems				Information Systems and Technology				Marine Systems				Total Goodwill
	December 31, 2014 (a)	$	2,555		$	2,750			$	6,137			$	289			$	11,731

	(a)Goodwill on December 31, 2014, in the Information Systems and Technology reporting unit is net of $1,994 of accumulated impairment losses.
	(b)Consists primarily of adjustments for foreign currency translation.
	Intangible assets consisted of the following:
		Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount				Gross Carrying Amount			Accumulated Amortization			Net Carrying Amount
		April 5, 2015									December 31, 2014
	Contract and program intangible assets*	$	1,654	$	(1,148	)	$	506			$	1,652		$	(1,123	)	$	529

	* Consists of acquired backlog and probable follow-on work and related customer relationships.
	Amortization expense was $30 for the three-month periods ended April 5, 2015, and March 30, 2014. We expect to record amortization expense of $120 in 2015.

Earnings Per Share [Abstract]
Earnings And Dividends Per Share	EARNINGS PER SHARE
	We compute basic earnings per share (EPS) using net earnings for the period and the weighted average number of common shares outstanding during the period. Basic weighted average shares outstanding have decreased throughout 2015 and 2014 due to share repurchases. See Note J for additional details of our share repurchases. Diluted EPS incorporates the additional shares issuable upon the assumed exercise of stock options and the release of restricted shares and restricted stock units (RSUs).
	Basic and diluted weighted average shares outstanding were as follows (in thousands):
	Three Months Ended	April 5, 2015	March 30, 2014
	Basic weighted average shares outstanding	329,154	342,232
	Dilutive effect of stock options and restricted stock/RSUs*	5,528	5,016
	Diluted weighted average shares outstanding	334,682	347,248
	* Excludes the following outstanding options to purchase shares of common stock because these options had exercise prices in excess of the average market price of our common stock during the period and therefore the effect of including these options would be antidilutive: 2015 - 722 and 2014 - 4,790.

Fair_Value_Of_Financial_Instru

Fair Value Disclosures [Abstract]
Fair Value Of Financial Instruments	FAIR VALUE
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between marketplace participants. Various valuation approaches can be used to determine fair value, each requiring different valuation inputs. The following hierarchy classifies the inputs used to determine fair value into three levels:
	•	Level 1 – quoted prices in active markets for identical assets or liabilities;
	•	Level 2 – inputs, other than quoted prices, observable by a marketplace participant either directly or indirectly; and
	•	Level 3 – unobservable inputs significant to the fair value measurement.
	We did not have any significant non-financial assets or liabilities measured at fair value on April 5, 2015, or December 31, 2014, except for the assets of our axle business that were classified as held for sale on December 31, 2014, and were measured at fair value using Level 3 inputs.
	Our financial instruments include cash and equivalents, marketable securities and other investments; accounts receivable and accounts payable; short- and long-term debt; and derivative financial instruments. The carrying values of cash and equivalents, accounts receivable and payable and short-term debt on the Consolidated Balance Sheets approximate their fair value. The following tables present the fair values of our other financial assets and liabilities on April 5, 2015, and December 31, 2014, and the basis for determining their fair values:
		Carrying			Fair			Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs
		Value			Value			(Level 1)		(Level 2) (a)

	(a)Determined under a market approach using valuation models that incorporate observable inputs such as interest rates, bond yields and quoted prices for similar assets and liabilities.
	(b)We had no Level 3 financial instruments on April 5, 2015, or December 31, 2014.

Income Taxes	INCOME TAXES
	Net Deferred Tax Assets. Our net deferred tax asset was included on the Consolidated Balance Sheets in other assets and liabilities as follows:
		April 5, 2015			December 31, 2014
	Current deferred tax asset	$	15		$	16
	Current deferred tax liability	(739		)	(729		)
	Noncurrent deferred tax asset	1,559			1,439
	Noncurrent deferred tax liability	(85		)	(82		)
	Net deferred tax asset	$	750		$	644
	Tax Uncertainties. For all periods open to examination by tax authorities, we periodically assess our liabilities and contingencies based on the latest available information. Where we believe there is more than a 50 percent chance that our tax position will not be sustained, we record our best estimate of the resulting tax liability, including interest, in the Consolidated Financial Statements. We include any interest or penalties incurred in connection with income taxes as part of income tax expense.
	We participate in the Internal Revenue Service (IRS) Compliance Assurance Process, a real-time audit of our consolidated federal corporate income tax return. The IRS has examined our consolidated federal income tax returns through 2013. We do not expect the resolution of tax matters for open years to have a material impact on our results of operations, financial condition, cash flows or effective tax rate.
	Based on all known facts and circumstances and current tax law, we believe the total amount of any unrecognized tax benefits on April 5, 2015, is not material to our results of operations, financial condition or cash flows, and if recognized, would not have a material impact on our effective tax rate. In addition, there are no tax positions for which it is reasonably possible that the unrecognized tax benefits will significantly vary over the next 12 months, producing, individually or in the aggregate, a material effect on our results of operations, financial condition or cash flows.

Contractors [Abstract]
Contracts In Process	CONTRACTS IN PROCESS
	Contracts in process represent recoverable costs and, where applicable, accrued profit related to long-term contracts that have been inventoried until the customer is billed, and consisted of the following:
		April 5, 2015			December 31, 2014
	Contract costs and estimated profits	$	7,390		$	7,494
	Other contract costs	1,061			1,064

	Advances and progress payments	(4,007		)	(3,967		)
	Total contracts in process	$	4,444		$	4,591
	Contract costs consist primarily of labor, material, overhead and G&A expenses. Other contract costs represent amounts that are not currently allocable to government contracts, such as a portion of our estimated workers’ compensation obligations, other insurance-related assessments, pension and other post-retirement benefits and environmental expenses. These costs will become allocable to contracts generally after they are paid. We expect to recover these costs through ongoing business, including existing backlog and probable follow-on contracts. If the backlog in the future does not support the continued deferral of these costs, the profitability of our remaining contracts could be adversely affected.

	Our inventories represent primarily business-jet components and are stated at the lower of cost or net realizable value. Work-in-process represents largely labor, material and overhead costs associated with aircraft in the manufacturing process and is based primarily on the estimated average unit cost of the units in a production lot. Raw materials are valued primarily on the first-in, first-out method. We record pre-owned aircraft acquired in connection with the sale of new aircraft at the lower of the trade-in value or the estimated net realizable value.
	Inventories consisted of the following:
		April 5, 2015		December 31, 2014

	Our fixed-rate notes are fully and unconditionally guaranteed by several of our 100-percent-owned subsidiaries (see Note O for condensed consolidating financial statements). We have the option to redeem the notes prior to their maturity in whole or part for the principal plus any accrued but unpaid interest and applicable make-whole amounts. In January 2015, we repaid $500 of fixed-rate notes on their scheduled maturity date.
	On April 5, 2015, we had no commercial paper outstanding, but we maintain the ability to access the commercial paper market in the future. We have $2 billion in committed bank credit facilities that provide backup liquidity to our commercial paper program. These credit facilities include a $1 billion multi-year facility expiring in July 2016 and a $1 billion multi-year facility expiring in July 2018. These facilities are required by rating agencies to support our commercial paper issuances. We may renew or replace, in whole or part, these credit facilities at or prior to their expiration dates. Our bank credit facilities are guaranteed by several of our 100-percent-owned subsidiaries. In addition, we have approximately $115 in committed bank credit facilities to provide backup liquidity to our European businesses.
	Our financing arrangements contain a number of customary covenants and restrictions. We were in compliance with all covenants on April 5, 2015.

	Total other liabilities	$	6,343	$	6,365
	(a)Consists primarily of dividends payable, taxes payable, environmental remediation reserves, warranty reserves, liabilities of discontinued operations and insurance-related costs.
	(b)Consists primarily of liabilities for warranty reserves and workers' compensation and liabilities of discontinued operations.
	The increase in the fair value of our cash flow hedge liabilities from December 31, 2014, to April 5, 2015, largely corresponds to the unrecognized losses on cash flow hedges deferred in accumulated other comprehensive loss (AOCL). These losses will be deferred in AOCL until the underlying transaction is reflected in earnings, at which time we believe the losses will be offset by corresponding gains in the remeasurement of the underlying transactions being hedged.

On February 9, 2015, with shares from the prior authorization largely exhausted, the board of directors authorized management to repurchase 10 million additional shares of common stock on the open market. On April 5, 2015, 7.7 million shares remained authorized by our board of directors for repurchase, approximately 2 percent of our total shares outstanding. We repurchased 29 million shares for a total of approximately $3.4 billion in 2014, including 14 million shares in the first three months of 2014.
	Dividends per Share. Dividends declared per share were $0.69 and $0.62 and for the three-month periods ended April 5, 2015, and March 30, 2014, respectively. Cash dividends paid were $206 and $198 for the three-month periods ended April 5, 2015 and March 30, 2014, respectively.
	Accumulated Other Comprehensive Loss. The changes, pretax and net of tax, in each component of AOCL consisted of the following:

	Amounts reclassified out of AOCL related primarily to changes in retirement plans' funded status and consisted of pretax recognized net actuarial losses of $112 and $76 for the three-month periods ended April 5, 2015, and March 30, 2014, respectively. This was partially offset by pretax amortization of prior service credit of $18 and $17 for the three-month periods ended April 5, 2015, and March 30, 2014, respectively. These AOCL components are included in our net periodic pension and other post-retirement benefit cost. See Note M for additional details.

Derivative_Instruments_And_Hed

Derivative Instruments And Hedging Activities	3 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments And Hedging Activities	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
	We are exposed to market risk, primarily from foreign currency exchange rates, interest rates, commodity prices and investments. We may use derivative financial instruments to hedge some of these risks as described below. We do not use derivatives for trading or speculative purposes.
	Foreign Currency Risk and Hedging Activities. Our foreign currency exchange rate risk relates to receipts from customers, payments to suppliers and inter-company transactions denominated in foreign currencies. To the extent possible, we include terms in our contracts that are designed to protect us from this risk. Otherwise, we enter into derivative financial instruments, principally foreign currency forward purchase and sale contracts, designed to offset and minimize our risk. The two-year average maturity of these instruments matches the duration of the activities that are at risk.
	We had $9 billion in notional forward exchange contracts outstanding on April 5, 2015, and $9.1 billion on December 31, 2014. We recognize derivative financial instruments on the Consolidated Balance Sheets at fair value (see Note D).
	We record changes in the fair value of derivative financial instruments in operating costs and expenses in the Consolidated Statements of Earnings or in other comprehensive loss (OCL) within the Consolidated Statements of Comprehensive Income depending on whether the derivative is designated and qualifies for hedge accounting. Gains and losses related to derivatives that qualify as cash flow hedges are deferred in OCL until the underlying transaction is reflected in earnings. We adjust derivative financial instruments not designated as cash flow hedges to market value each period and record the gain or loss in the Consolidated Statements of Earnings. The gains and losses on these instruments generally offset losses and gains on the assets, liabilities and other transactions being hedged. Gains and losses resulting from hedge ineffectiveness are recognized in the Consolidated Statements of Earnings for all derivative financial instruments, regardless of designation.
	Net gains and losses recognized in earnings, including gains and losses related to hedge ineffectiveness, were not material to our results of operations for the three-month periods ended April 5, 2015, and March 30, 2014. Net gains and losses reclassified to earnings from OCL were not material to our results of operations for the three-month periods ended April 5, 2015, and March 30, 2014, and we do not expect the amount of these gains and losses that will be reclassified to earnings during the next 12 months to be material.
	We had no material derivative financial instruments designated as fair value or net investment hedges on April 5, 2015, or December 31, 2014.
	Interest Rate Risk. Our financial instruments subject to interest rate risk include fixed-rate long-term debt obligations and variable-rate commercial paper. However, the risk associated with these instruments is not material.
	Commodity Price Risk. We are subject to risk of rising labor and commodity prices, primarily on long-term fixed-price contracts. To the extent possible, we include terms in our contracts that are designed to protect us from this risk. Some of the protective terms included in our contracts are considered derivatives but are not accounted for separately because they are clearly and closely related to the host contract. We have not entered into any material commodity hedging contracts but may do so as circumstances warrant. We do not believe that changes in labor or commodity prices will have a material impact on our results of operations or cash flows.
	Investment Risk. Our investment policy allows for purchases of fixed-income securities with an investment-grade rating and a maximum maturity of up to five years. On April 5, 2015, we held $4.4 billion in cash and equivalents, but held no marketable securities.
	Foreign Currency Financial Statement Translation. We translate foreign currency balance sheets from our international businesses' functional currency (generally the respective local currency) to U.S. dollars at the end-of-period exchange rates, and statements of earnings at the average exchange rates for each period. The resulting foreign currency translation adjustments are a component of OCL.
	We do not hedge the fluctuation in reported revenues and earnings resulting from the translation of these international operations' results into U.S. dollars. The impact of translating our non-U.S. operations’ revenues and earnings into U.S. dollars was not material to our results of operations for the three-month periods ended April 5, 2015, or March 30, 2014. In addition, the effect of changes in foreign exchange rates on non-U.S. cash balances was not material in the first three months of either 2015 or 2014.

Commitments_And_Contingencies

Commitments And Contingencies	3 Months Ended
	Apr. 05, 2015
Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES
	Litigation
	Various claims and other legal proceedings incidental to the normal course of business are pending or threatened against us. These matters relate to such issues as government investigations and claims, the protection of the environment, asbestos-related claims and employee-related matters. The nature of litigation is such that we cannot predict the outcome of these matters. However, based on information currently available, we believe any potential liabilities in these proceedings, individually or in the aggregate, will not have a material impact on our results of operations, financial condition or cash flows.
	Environmental
	We are subject to and affected by a variety of federal, state, local and foreign environmental laws and regulations. We are directly or indirectly involved in environmental investigations or remediation at some of our current and former facilities and third-party sites that we do not own but where we have been designated a Potentially Responsible Party (PRP) by the U.S. Environmental Protection Agency or a state environmental agency. Based on historical experience, we expect that a significant percentage of the total remediation and compliance costs associated with these facilities will continue to be allowable contract costs and, therefore, recoverable under U.S. government contracts.
	As required, we provide financial assurance for certain sites undergoing or subject to investigation or remediation. We accrue environmental costs when it is probable that a liability has been incurred and the amount can be reasonably estimated. Where applicable, we seek insurance recovery for costs related to environmental liabilities. We do not record insurance recoveries before collection is considered probable. Based on all known facts and analyses, we do not believe that our liability at any individual site, or in the aggregate, arising from such environmental conditions, will be material to our results of operations, financial condition or cash flows. We also do not believe that the range of reasonably possible additional loss beyond what has been recorded would be material to our results of operations, financial condition or cash flows.
	Other
	Government Contracts. As a government contractor, we are subject to U.S. government audits and investigations relating to our operations, including claims for fines, penalties, and compensatory and treble damages. We believe the outcome of such ongoing government audits and investigations will not have a material impact on our results of operations, financial condition or cash flows.
	In the performance of our contracts, we routinely request contract modifications that require additional funding from the customer. Most often, these requests are due to customer-directed changes in the scope of work. While we are entitled to recovery of these costs under our contracts, the administrative process with our customer may be protracted. Based upon the circumstances, we periodically file requests for equitable adjustment (REAs) that are sometimes converted into claims. In some cases, these requests are disputed by our customer. We believe our outstanding modifications and other claims will be resolved without material impact to our results of operations, financial condition or cash flows.
	Letters of Credit and Guarantees. In the ordinary course of business, we have entered into letters of credit, bank guarantees, surety bonds and other similar arrangements with financial institutions and insurance carriers totaling approximately $972 on April 5, 2015. In addition, from time to time and in the ordinary course of business, we contractually guarantee the payment or performance obligations of our subsidiaries arising under certain contracts.
	Aircraft Trade-ins. In connection with orders for new aircraft in funded contract backlog, our Aerospace group has outstanding options with some customers to trade in aircraft as partial consideration in their new-aircraft transaction. These trade-in commitments are structured to establish the fair market value of the trade-in aircraft at a date generally 120 or fewer days preceding delivery of the new aircraft to the customer. At that time, the customer is required to either exercise the option or allow its expiration. Any excess of the pre-established trade-in price above the fair market value at the time the new outfitted aircraft is delivered is treated as a reduction of revenue in the new-aircraft sales transaction.
	Product Warranties. We provide warranties to our customers associated with certain product sales. We record estimated warranty costs in the period in which the related products are delivered. The warranty liability recorded at each balance sheet date is generally based on the number of months of warranty coverage remaining for products delivered and the average historical monthly warranty payments. Warranty obligations incurred in connection with long-term production contracts are accounted for within the contract estimates at completion. Our other warranty obligations, primarily for business-jet aircraft, are included in other current and noncurrent liabilities on the Consolidated Balance Sheets.
	The changes in the carrying amount of warranty liabilities for the three-month periods ended April 5, 2015, and March 30, 2014, were as follows:
	Three Months Ended	April 5, 2015			March 30, 2014
	Beginning balance	$	428		$	354

	We provide defined-contribution benefits, as well as some remaining defined-benefit pension and other post-retirement benefits.
	Net periodic cost associated with our defined-benefit pension and other post-retirement benefit plans for the three-month periods ended April 5, 2015, and March 30, 2014, consisted of the following:
		Pension Benefits						Other Post-retirement Benefits

	Amortization of prior service credit	(17		)	(17		)	(1		)	—
	Net periodic cost	$	109		$	74		$	7		$	10
	Our contractual arrangements with the U.S. government provide for the recovery of contributions to our pension and other post-retirement benefit plans covering employees working in our defense business groups. For non-funded plans, our government contracts allow us to recover claims paid. Following payment, these recoverable amounts are allocated to contracts and billed to the customer in accordance with the Cost Accounting Standards (CAS) and specific contractual terms. For some of these plans, the cumulative pension and post-retirement benefit cost exceeds the amount currently allocable to contracts. To the extent recovery of the cost is considered probable based on our backlog and probable follow-on contracts, we defer the excess in contracts in process on the Consolidated Balance Sheets until the cost is allocable to contracts. See Note F for discussion of our deferred contract costs. For other plans, the amount allocated to contracts and included in revenues has exceeded the plans’ cumulative benefit cost. We have deferred recognition of these excess earnings to provide a better matching of revenues and expenses. These deferrals have been classified against the plan assets on the Consolidated Balance Sheets.

Business Group Information	BUSINESS GROUP INFORMATION
	We operate in four business groups: Aerospace, Combat Systems, Information Systems and Technology and Marine Systems. We organize our business groups in accordance with the nature of products and services offered. These business groups derive their revenues from business aviation; combat vehicles, weapons systems and munitions; communication and information technology systems and solutions; and military and commercial shipbuilding and services, respectively. We measure each group’s profit based on operating earnings. As a result, we do not allocate net interest, other income and expense items, and income taxes to our business groups.
	Summary financial information for each of our business groups follows:

Summary_Of_Significant_Account1

Summary Of Significant Accounting Policies (Policies)	3 Months Ended
	Apr. 05, 2015
Accounting Policies [Abstract]
Basis of Consolidation and Classification	Basis of Consolidation and Classification. The unaudited Consolidated Financial Statements include the accounts of General Dynamics Corporation and our wholly owned and majority-owned subsidiaries. We eliminate all inter-company balances and transactions in the unaudited Consolidated Financial Statements.
	Consistent with defense industry practice, we classify assets and liabilities related to long-term production contracts as current, even though some of these amounts may not be realized within one year. In addition, some prior-year amounts have been reclassified among financial statement accounts to conform to the current-year presentation.
Interim Financial Statements	Interim Financial Statements. The unaudited Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. These rules and regulations permit some of the information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) to be condensed or omitted.
	Our fiscal quarters are 13 weeks in length. Because our fiscal year ends on December 31, the number of days in our first and fourth quarters varies slightly from year to year. Operating results for the three-month period ended April 5, 2015, are not necessarily indicative of the results that may be expected for the year ending December 31, 2015.
	The unaudited Consolidated Financial Statements contain all adjustments that are of a normal recurring nature necessary for a fair presentation of our results of operations and financial condition for the three-month periods ended April 5, 2015, and March 30, 2014.
	These unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2014.
Revenue Recognition	Revenue Recognition. We account for revenues and earnings using the percentage-of-completion method. Under this method, contract costs and revenues are recognized as the work progresses, either as the products are produced or as services are rendered. We estimate the profit on a contract as the difference between the total estimated revenue and costs to complete a contract and recognize that profit over the life of the contract. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we recognize the loss in the quarter it is identified.
	We review and update our contract-related estimates regularly. We recognize changes in estimated profit on contracts under the reallocation method. Under the reallocation method, the impact of a revision in estimate is recognized prospectively over the remaining contract term. The net increase in our operating earnings (and on a per-share basis) from the impact of revisions in contract estimates totaled favorable changes of $63 ($0.12) and $38 ($0.07) for the three-month periods ended April 5, 2015, and March 30, 2014, respectively. No revisions on any one contract were material to our unaudited Consolidated Financial Statements in the first quarter of 2015 or 2014.
	In the second quarter of 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers. ASU 2014-09 prescribes a single, common revenue standard that replaces most existing revenue recognition guidance in GAAP. The standard outlines a five-step model, whereby revenue is recognized as performance obligations within a contract are satisfied. The standard also requires new, expanded disclosures regarding revenue recognition.
	For public companies, ASU 2014-09 is effective in the first quarter of 2017. On April 1, 2015, the FASB proposed a one-year deferral of the standard's effective date, while permitting entities to still adopt one year earlier on the original effective date. A final determination will be made after a public comment period. The standard permits the use of either the retrospective or cumulative effect transition method. We have not yet selected a transition date or method nor have we determined the effect of the standard on our consolidated financial statements as the standard continues to undergo changes.
	The required adoption of the ASU will preclude our use of the reallocation method of recognizing revisions in estimated profit on contracts discussed above. As changes in estimated profit will be recognized in the period they are identified (cumulative catch-up method), rather than prospectively over the remaining contract term, we expect that the impact of revisions of contract estimates may be larger and potentially more variable from period to period. Anticipated losses on contracts will continue to be recognized in the quarter they are identified.
Discontinued Operations	Discontinued Operations. We completed the sale of our axle business in the Combat Systems group in January 2015. The financial statements have been restated to reflect the results of operations of this business in discontinued operations.
Subsequent Events	Subsequent Events. We have evaluated material events and transactions that have occurred after April 5, 2015, and concluded that none have occurred that require adjustment to or disclosure in the unaudited Consolidated Financial Statements.
