Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Organization. General Dynamics is organized into four business groups: Aerospace, which produces Gulfstream aircraft, provides aircraft services and performs aircraft completions for other original equipment manufacturers (OEMs); Combat Systems, which designs and manufactures combat vehicles, weapons systems and munitions; Information Systems and Technology, which provides communications and information technology systems and solutions; and Marine Systems, which designs, constructs and repairs surface ships and submarines. Our primary customer is the U.S. government. We also do significant business with non-U.S. governments and a diverse base of corporate and individual buyers of business aircraft.
	Basis of Consolidation and Classification. The 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 Consolidated Financial Statements.
	Consistent with defense industry practice, we classify assets and liabilities related to long-term 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.
	Use of Estimates. The nature of our business requires that we make a number of estimates and assumptions in accordance with U.S. generally accepted accounting principles (GAAP). These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. We base our estimates on historical experience, currently available information and various other assumptions that we believe are reasonable under the circumstances. Actual results could differ from these estimates.
	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 generally measure progress toward completion on contracts in our defense business based on the proportion of costs incurred to date relative to total estimated costs at completion. For our contracts for the manufacture of business-jet aircraft, we record revenue at two contractual milestones: when green aircraft are delivered to and accepted by the customer and when the customer accepts final delivery of the fully outfitted aircraft.
	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 $184 ($0.35) in 2014, $351 ($0.65) in 2013 and $180 ($0.33) in 2012. The 2013 impact of changes in estimate was higher as a result of numerous programs that neared completion in the Combat Systems group. No revisions on any one contract were material to our Consolidated Financial Statements in 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. ASU 2014-09 is effective in the first quarter of 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We have not yet selected a transition method nor have we determined the effect of the standard on our Consolidated Financial Statements.
	The required adoption of the ASU in 2017 will preclude our use of the reallocation method of recognizing revisions in estimated profit on contracts discussed previously. 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. In 2014, we entered into an agreement to sell our axle business in the Combat Systems group and recognized a $146 loss, net of tax (the sale was completed in January 2015). The financial statements have been restated to reflect the results of operations of this business in discontinued operations with the revenues of the business eliminated, and the net loss reported separately below earnings from continuing operations.
	In 2013, we recognized a $129 loss, net of tax, from the settlement of our litigation with the U.S. Navy related to the terminated A-12 contract in the company’s discontinued tactical military aircraft business. Under the terms of the settlement agreement, the Navy received a $198 credit that will be utilized over several years as we render design and construction services on the DDG-1000 program. Net cash from discontinued operations on the Consolidated Statements of Cash Flows primarily represents activity associated with the A-12 settlement and related work on the DDG-1000 program.
	Research and Development Expenses. Company-sponsored research and development (R&D) expenses, including product development costs, were $358 in 2014, $310 in 2013 and $374 in 2012. R&D expenses are included in operating costs and expenses in the Consolidated Statements of Earnings (Loss) in the period in which they are incurred. Customer-sponsored R&D expenses are charged directly to the related contracts.
	The Aerospace group has cost-sharing arrangements with some of its suppliers that enhance the group’s internal development capabilities and offset a portion of the financial cost associated with the group’s product development efforts. These arrangements explicitly state that supplier contributions are for reimbursements of costs we incur in the development of new aircraft models and technologies, and we retain substantial rights in the products developed under these arrangements. We record amounts received from these cost-sharing arrangements as a reduction of R&D expenses. We have no obligation to refund any amounts received under the agreements regardless of the outcome of the development efforts. Under the typical terms of an agreement, payments received from suppliers for their share of the costs are based on milestones and are recognized as received.
	Interest, Net. Net interest expense consisted of the following:
	Year Ended December 31	2014			2013			2012
	Interest expense	$	103		$	103		$	168
	Interest income	(17		)	(17		)	(12		)
	Interest expense, net	$	86		$	86		$	156
	Interest payments	$	94		$	94		$	186
	Cash and Equivalents and Investments in Debt and Equity Securities. We consider securities with a maturity of three months or less to be cash equivalents. Our investments in other securities (see Note D) are included in other current and noncurrent assets on the Consolidated Balance Sheets. We report our held-to-maturity securities at amortized cost. We report our available-for-sale securities at fair value. Changes in the fair value of available-for-sale securities are recognized as a component of other comprehensive income (loss) in the Consolidated Statements of Comprehensive Income (Loss). We had no trading securities on December 31, 2014 or 2013.
	Net (purchases) proceeds of other securities were ($497) in 2014, including the purchase of $500 of held-to-maturity securities, ($22) in 2013 and $219 in 2012. Net proceeds in 2012 include $224 and $211 of maturities and sales of held-to-maturity securities, respectively, included in other investing activities on the Consolidated Statements of Cash Flows.
	Long-lived Assets and Goodwill. We review long-lived assets, including intangible assets subject to amortization, for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. We assess the recoverability of the carrying value of assets held for use based on a review of undiscounted projected cash flows. Impairment losses, where identified, are measured as the excess of the carrying value of the long-lived asset over its fair value as determined by discounted projected cash flows.
	We review goodwill for impairment annually or when circumstances indicate that an impairment is more likely than not. Goodwill represents the purchase price paid in excess of the fair value of net tangible and intangible assets acquired. The test for goodwill impairment is a two-step process to first identify potential goodwill impairment for each reporting unit and then, if necessary, measure the amount of the impairment loss. Our reporting units are consistent with our business groups in Note Q. For a summary of our goodwill by reporting unit, see Note B.
	Subsequent Events. In January 2015, we repaid $500 of fixed-rate notes on their scheduled maturity date with the proceeds from maturing marketable securities.
	We have evaluated other material events and transactions that have occurred after December 31, 2014, and concluded that none have occurred that require an adjustment to or disclosure in the Consolidated Financial Statements.

Goodwill and Intangible Assets Disclosure [Abstract]
Acquisitions, Divestitures, Goodwill and Intangible Assets	ACQUISITIONS, GOODWILL AND INTANGIBLE ASSETS
	Acquisitions
	In 2014, we acquired a provider of mission-critical IT and networking support in our Information Systems and Technology group. We did not acquire any businesses in 2013. In 2012, we acquired seven businesses across our business groups for a total of $444. These amounts are included in other investing activities on the Consolidated Statements of Cash Flows.
	The operating results of these acquisitions have been included with our reported results since their respective closing dates. The purchase prices of these acquisitions have been allocated to the estimated fair value of net tangible and intangible assets acquired, with any excess purchase price recorded as goodwill.
	Goodwill
	The changes in the carrying amount of goodwill by reporting unit were as follows:
		Aerospace				Combat Systems				Information Systems and Technology				Marine Systems				Total Goodwill
	December 31, 2012 (a)	$	2,697			$	2,916			$	6,100			$	290			$	12,003
	Acquisitions (b)	—				2				1				(1		)		2
	Other (c)	44				(69		)		(48		)		—				(73		)
	December 31, 2013	$	2,741			$	2,849			$	6,053			$	289			$	11,932
	Acquisitions (b)	—				—				127				—				127
	Other (c)	(186		)		(99		)		(43		)		—				(328		)
	December 31, 2014	$	2,555			$	2,750			$	6,137			$	289			$	11,731
	(a)Goodwill on December 31, 2012, in the Information Systems and Technology reporting unit is net of $1,994 of accumulated impairment losses.
	(b)Includes adjustments during the purchase price allocation period.
	(c)Consists primarily of adjustments for foreign currency translation.
	We completed the required annual goodwill impairment test as of December 31, 2014. The first step of the goodwill impairment test compares the fair values of our reporting units to their carrying values. We estimate the fair values of our reporting units primarily based on the discounted projected cash flows of the underlying operations. The estimated fair values for each of our reporting units were well in excess of their respective carrying values as of December 31, 2014. In our Information Systems and Technology reporting unit (for which we recorded a $2 billion goodwill impairment in 2012 discussed in the paragraph below), this excess increased from 2013 as there was an improvement in the fair value and a decrease in the carrying value of the reporting unit.
	In 2012, we recorded a $2 billion goodwill impairment in the Information Systems and Technology reporting unit. Revenue pressure from slowed defense spending and the threat of sequestration and margin compression due to mix shift impacted operating results and tempered the projected cash flows of the reporting unit, which negatively impacted our estimate of its fair value. Prior to December 31, 2012, we had no accumulated impairment losses.
	Intangible Assets
	Intangible assets consisted of the following:
		Gross Carrying Amount			Accumulated Amortization			Net Carrying Amount				Gross Carrying Amount			Accumulated Amortization			Net Carrying Amount
		December 31, 2014										December 31, 2013
	Contract and program intangible assets*	$	1,652		$	(1,123	)	$	529			$	1,790		$	(1,189	)	$	601
	Trade names and trademarks	462			(113		)	349				507			(103		)	404
	Technology and software	130			(97		)	33				130			(92		)	38
	Other intangible assets	154			(153		)	1				155			(154		)	1
	Total intangible assets	$	2,398		$	(1,486	)	$	912			$	2,582		$	(1,538	)	$	1,044
	* Consists of acquired backlog and probable follow-on work and associated customer relationships.
	The decrease in the gross carrying amount and accumulated amortization of contract and program intangible assets from December 31, 2013, to December 31, 2014, is primarily due to the write-off of fully amortized assets in the Information Systems and Technology group.
	We did not recognize any impairments of our intangible assets in 2014 or 2013. In 2012, we recognized impairments in our Aerospace and Information Systems and Technology groups of $191 and $110, respectively, on contract and program, and related technology intangible assets for substantially all of their remaining values. These losses were reported in operating costs and expenses in the respective segments.
	The amortization lives (in years) of our intangible assets on December 31, 2014, were as follows:
			Range of
			Amortization Life
	Contract and program intangible assets		30-Jul
	Trade names and trademarks		30
	Technology and software		15-Jul
	Other intangible assets		5
	Amortization expense was $121 in 2014, $143 in 2013 and $214 in 2012. We expect to record annual amortization expense over the next five years as follows:
	2015	$	121
	2016	95
	2017	81
	2018	70
	2019	57

Earnings Per Share [Abstract]
Earnings 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 2014 and 2013 due to share repurchases. See Note L 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):
	Year Ended December 31	2014	2013	2012
	Basic weighted average shares outstanding	335,192	350,714	353,346
	Dilutive effect of stock options and restricted stock/RSUs*	6,139	2,785	—
	Diluted weighted average shares outstanding	341,331	353,499	353,346
	* 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 year and therefore the effect of including these options would be antidilutive: 2014 - 3,683; 2013 - 8,246 and 2012 - 23,672. Additionally, because of the net loss in 2012, 2,353 otherwise dilutive stock options and restricted stock/RSUs were not included in the calculation of diluted EPS. The inclusion of these dilutive stock options and restricted stock/RSUs would have improved the diluted loss per share. For this reason, diluted EPS in 2012 was calculated using the same number of weighted average shares as basic EPS.

Fair Value Disclosures [Abstract]
Fair Value	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 December 31, 2014 or 2013, except for the assets of our axle business that are classified as held for sale on December 31, 2014 and were measured at fair value using Level 3 inputs. See Note A for further discussion.
	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 table presents the fair values of our other financial assets and liabilities on December 31, 2014 and 2013, 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)

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES
	Income Tax Provision. We calculate our provision for federal, state and international income taxes based on current tax law. The reported tax provision differs from the amounts currently receivable or payable because some income and expense items are recognized in different time periods for financial reporting than for income tax purposes. The following is a summary of our net provision for income taxes for continuing operations:
	Year Ended December 31	2014				2013				2012
	Current:
	U.S. federal	$	856			$	850			$	876
	State	31				28				(9		)
	International	106				132				131
	Total current	993				1,010				998
	Deferred:
	U.S. federal	110				119				(168		)
	State	(3		)		1				(5		)
	International	29				(5		)		29
	Total deferred	136				115				(144		)
	Provision for income taxes, net	$	1,129			$	1,125			$	854
	Net income tax payments	$	1,019			$	888			$	1,155
	State and local income taxes allocable to U.S. government contracts are included in operating costs and expenses in the Consolidated Statements of Earnings (Loss) and, therefore, not included in the provision above.
	The reconciliation from the statutory federal income tax rate to our effective income tax rate follows:
	Year Ended December 31	2014			2013			2012
	Statutory federal income tax rate	35	%		35	%		35	%
	State tax on commercial operations, net of federal benefits	0.5			0.7			(1.8	)
	Impact of international operations	(2.6	)		—			61.9
	Domestic production deduction	(1.9	)		(2.2	)		(12.9	)
	Domestic tax credits	(0.7	)		(0.8	)		(1.6	)
	Goodwill impairment	—			—			105.9
	Other, net	(0.6	)		(1.5	)		(6.0	)
	Effective income tax rate	29.7	%		31.2	%		180.5	%
	The decrease in the effective tax rate in 2014 was primarily due to increased income from non-U.S. operations that is taxed at lower rates and utilization of foreign tax credits. Our 2012 effective tax rate was unfavorably impacted by the non-deductible nature of a substantial portion of our goodwill, for which there was a limited tax benefit recognized on the impairment. In addition, due to the unfavorable market conditions impacting certain of our international subsidiaries, a valuation allowance was established for their net deferred tax assets, including the operating losses resulting from the charges at our European Land Systems business in 2012.
	Net Deferred Tax Assets. The tax effects of temporary differences between reported earnings and taxable income consisted of the following:
	31-Dec	2014				2013
	Retirement benefits	$	1,403			$	783
	Tax loss and credit carryforwards	701				581
	Salaries and wages	301				249
	Workers’ compensation	257				272
	A-12 contract termination	—				163
	Other	363				306
	Deferred assets	3,025				2,354
	Valuation allowances	(494		)		(383		)
	Net deferred assets	$	2,531			$	1,971
	Intangible assets	$	(973	)		$	(937	)
	Contract accounting methods	(227		)		(322		)
	Property, plant and equipment	(280		)		(269		)
	Capital Construction Fund/Qualified Ships	(240		)		(240		)
	Other	(167		)		(141		)
	Deferred liabilities	$	(1,887	)		$	(1,909	)
	Net deferred tax asset	$	644			$	62
	Our net deferred tax asset was included on the Consolidated Balance Sheets in other assets and liabilities as follows:
	31-Dec	2014				2013
	Current deferred tax asset	$	16			$	35
	Current deferred tax liability	(729		)		(300		)
	Noncurrent deferred tax asset	1,439				462
	Noncurrent deferred tax liability	(82		)		(135		)
	Net deferred tax asset	$	644			$	62
	We believe it is more likely than not that we will generate sufficient taxable income in future periods to realize our deferred tax assets, subject to the valuation allowances recognized.
	Our retirement benefits deferred tax amount includes a deferred tax asset of $1.8 billion on December 31, 2014, and $1.2 billion on December 31, 2013, related to the amounts recorded in accumulated other comprehensive loss to recognize the funded status of our retirement plans. See Notes L and P for further discussion.
	One of our deferred tax liabilities results from our participation in the Capital Construction Fund (CCF), a program established by the U.S. government and administered by the Maritime Administration that supports the acquisition, construction, reconstruction or operation of U.S. flag merchant marine vessels. The program allows us to defer federal and state income taxes on earnings derived from eligible programs as long as the proceeds are deposited in the fund and withdrawals are used for qualified activities. We had U.S. government accounts receivable pledged (and thereby deposited) to the CCF of $100 on December 31, 2014, and $459 on December 31, 2013. The decrease in the fund in 2014 was due to qualified withdrawals to build ships, the proceeds from the sale of which we expect to re-deposit into the fund.
	On December 31, 2014, we had net operating loss carryforwards of $1.2 billion that begin to expire in 2017 and tax credit carryforwards of $215 that begin to expire in 2015.
	Earnings from continuing operations before income taxes included non-U.S. income (loss) of $507 in 2014, $361 in 2013 and ($215) in 2012. We intend to reinvest indefinitely the undistributed earnings of some of our non-U.S. subsidiaries. On December 31, 2014, we had approximately $1.9 billion of undistributed earnings from these non-U.S. subsidiaries. In general, should these earnings be distributed, a portion would be treated as dividends under U.S. tax law and thus subject to U.S. federal corporate income tax at the statutory rate of 35 percent, but would generate offsetting foreign tax credits.
	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 believe we are entitled to interest under the Internal Revenue Code resulting from the completion of the A-12 contract triggered by the settlement of the associated litigation. The interest would be recognized when the amount is determined to be realizable, likely upon finalization of our 2014 consolidated federal corporate income tax return. See Note A to the Consolidated Financial Statements for further discussion of the A-12 settlement.
	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 December 31, 2014, 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.

Accounts Receivable, Net [Abstract]
Accounts Receivable	ACCOUNTS RECEIVABLE
	Accounts receivable represent amounts billed and currently due from customers and consisted of the following:
	31-Dec	2014		2013
	Non-U.S. government	$	2,529	$	2,767
	U.S. government	822		951

	Total accounts receivable	$	4,050	$	4,370
	Receivables from non-U.S. government customers include amounts related to long-term production programs for the Spanish Ministry of Defence of $2.3 billion on December 31, 2014. A different ministry, the Spanish Ministry of Industry, has funded work on these programs in advance of costs incurred by the company. The cash advances are reported on the Consolidated Balance Sheets in current customer advances and deposits and will be repaid to the Ministry of Industry as we collect on the outstanding receivables from the Ministry of Defence. The net amount for these programs on December 31, 2014, is an advance payment of $21. With respect to our other receivables, we expect to collect substantially all of the December 31, 2014, balance during 2015.

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:
	31-Dec	2014			2013
	Contract costs and estimated profits	$	7,494		$	7,961
	Other contract costs	1,064			1,178

	Advances and progress payments	(3,967		)	(4,359		)
	Total contracts in process	$	4,591		$	4,780
	Contract costs consist primarily of labor, material, overhead and G&A expenses. Contract costs also may include estimated contract recoveries for matters such as contract changes and claims for unanticipated contract costs. We record revenue associated with these matters only when the amount of recovery can be estimated reliably and realization is probable. Assumed recoveries for claims included in contracts in process were not material on December 31, 2014 or 2013.
	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.
	Excluding our other contract costs, we expect to bill all but approximately 15 percent of our year-end 2014 contracts-in-process balance during 2015. Of the amount not expected to be billed in 2015, approximately $220 relates to a single contract, the Canadian Maritime Helicopter Project (MHP). In 2014, the contract was renegotiated, extending the period of performance. The MHP-related balance declined by $80 during 2014.

Shareholders' Equity	SHAREHOLDERS’ EQUITY
	Authorized Stock. Our authorized capital stock consists of 500 million shares of $1 per share par value common stock and 50 million shares of $1 per share par value preferred stock. The preferred stock is issuable in series, with the rights, preferences and limitations of each series to be determined by our board of directors.
	Shares Issued and Outstanding. On December 31, 2014, we had 481,880,634 shares of common stock issued and 332,164,097 shares of common stock outstanding, including unvested restricted stock of 1,721,938 shares. On December 31, 2013, we had 481,880,634 shares of common stock issued and 353,402,794 shares of common stock outstanding. No shares of our preferred stock were outstanding on either date. The only changes in our shares outstanding during 2014 resulted from shares repurchased in the open market and share activity under our equity compensation plans (see Note O for further discussion).
	Share Repurchases. In 2014, we repurchased 29 million of our outstanding shares. Of this amount, 11.4 million shares were repurchased on January 24, 2014, for $1.4 billion under an accelerated share repurchase (ASR) program facilitated through a financial institution. On February 5, 2014, with shares from the prior authorization largely exhausted by the ASR program, the board of directors authorized management to repurchase 20 million additional shares of common stock on the open market. Subsequently, we repurchased an additional 17.6 million shares for approximately $2 billion. On December 31, 2014, 2.4 million shares remained authorized by our board of directors for repurchase, less than 1 percent of our total shares outstanding.
	Dividends per Share. Dividends declared per share were $2.48 in 2014, $2.24 in 2013 and $2.04 in 2012. Cash dividends paid were $822 in 2014, $591 in 2013 and $893 in 2012. In advance of possible tax increases in 2013, we accelerated our first-quarter 2013 dividend payment to December 2012.

	Amounts reclassified out of AOCL related primarily to changes in retirement plans' funded status and included pretax recognized net actuarial losses of $329 and $435 for the years ended December 31, 2014 and 2013, respectively. This was partially offset by pretax amortization of prior service credit of $69 and $60 for the years ended December 31, 2014 and 2013, respectively. These AOCL components are included in our net periodic pension and other post-retirement benefit cost. See Note P for additional details.

Derivative_Instruments_And_Hed

Derivative Instruments And Hedging Activities	12 Months Ended
	Dec. 31, 2014
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 $9.1 billion in notional forward exchange contracts outstanding on December 31, 2014, and $1.7 billion on December 31, 2013. The increase in 2014 is due to significant international contract awards. 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 (Loss) or in other comprehensive loss (OCL) within the Consolidated Statements of Comprehensive Income (Loss) 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 (Loss). 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 (Loss) 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 in any of the past three years. Net gains and losses reclassified to earnings from OCL were not material to our results of operations in any of the past three years, and we do not expect the amount of these gains and losses that will be reclassified to earnings in 2015 to be material.
	We had no material derivative financial instruments designated as fair value or net investment hedges on December 31, 2014 or 2013.
	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 December 31, 2014, we held $4.4 billion in cash and equivalents and $500 of marketable securities reported in other current assets. Our marketable securities had an average duration of less than one month and an average credit rating of AA-. Historically, we have not experienced material gains or losses on these instruments due to changes in interest rates or market values.
	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 international operations’ revenues and earnings into U.S. dollars was not material to our results of operations in any of the past three years. In addition, the effect of changes in foreign exchange rates on non-U.S. cash balances was not material in each of the past three years.

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.
	Minimum Lease Payments
	Total expense under operating leases was $297 in 2014, $309 in 2013 and $298 in 2012. Operating leases are primarily for facilities and equipment. Future minimum lease payments are as follows:
	Year Ended December 31
	2015	$	210
	2016	181
	2017	132
	2018	100
	2019	72
	Thereafter	383
	Total minimum lease payments	$	1,078
	Other
	Portugal Program. In 2014, we reached a settlement with the Portuguese Ministry of National Defense and Ministry of Economy relating to a dispute arising from a contract in our Combat Systems group’s European Land Systems business to provide armored vehicles for which we had accrued $258 in 2012. The settlement provides for the delivery of vehicles and a significant reduction in our offset obligations and related bank guarantees. The settlement did not have a material impact on our 2014 results of operations, financial condition or cash flows as our liability was generally consistent with the amount previously recorded.
	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 $1 billion on December 31, 2014. 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.
	Labor Agreements. Approximately one-fifth of the employees of our subsidiaries work under collectively-bargained terms and conditions, including 55 collective agreements that we have negotiated directly with unions and works councils. A number of these agreements expire within any given year. Historically, we have been successful at negotiating successor agreements without any material disruption of operating activities. In 2015, we expect to negotiate the terms of 15 agreements covering approximately 2,400 employees. We do not expect the renegotiations will, either individually or in the aggregate, have a material impact on our results of operations, financial condition or cash flows.
	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 the 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 each of the past three years were as follows:
	Year Ended December 31	2014			2013			2012
	Beginning balance	$	354		$	316		$	291
	Warranty expense	146			125			91
	Payments	(78		)	(82		)	(58		)

Equity_Compensation_Plans

Equity Compensation Plans	12 Months Ended
	Dec. 31, 2014
Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity Compensation Plans	EQUITY COMPENSATION PLANS
	Equity Compensation Overview. We have various equity compensation plans for employees, as well as for non-employee members of our board of directors. The equity compensation plans seek to provide an effective means of attracting, retaining and motivating directors, officers and key employees, and to provide them with incentives to enhance our growth and profitability. Under the equity compensation plans, awards may be granted to officers, employees or non-employee directors in common stock, options to purchase common stock, restricted shares of common stock, participation units or any combination of these.
	Stock options granted under the equity compensation plans are issued with an exercise price at the fair market value of the common stock on the date of grant. Outstanding awards of stock options vest over two years, with 50 percent of the options vesting in one year and the remaining 50 percent vesting the following year. Stock options that have been awarded under the equity compensation plans expire five or seven years after the grant date. We grant annual stock option awards to participants in the equity compensation plans on the first Wednesday of March based on the average of the high and low stock prices on that day as listed on the New York Stock Exchange. We may make limited ad hoc grants at other times during the year for new hires or promotions.
	Grants of restricted stock are awards of shares of common stock that vest approximately four years after the grant date. During the restriction period, recipients may not sell, transfer, pledge, assign or otherwise convey their restricted shares to another party. However, during this period, the recipient is entitled to vote the restricted shares and receive cash dividends on those shares.
	Participation units represent obligations that have a value derived from or related to the value of our common stock. These include stock appreciation rights, phantom stock units and restricted stock units (RSUs) and are payable in cash or common stock. Like restricted stock, participation units vest approximately four years after the grant date with recipients prohibited from certain activities during the restriction period. However, during this period, the recipient receives dividend-equivalent units rather than cash dividends, and is not entitled to vote the participation units or the dividend-equivalent units.
	Beginning in 2012, we granted RSUs with a performance measure based on a non-GAAP management metric, return on invested capital (ROIC). Depending on the company’s performance with respect to this metric, the number of RSUs earned may be less than, equal to or greater than the original number of RSUs awarded. For a definition of ROIC, see Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in Item 7.
	We issue common stock under our equity compensation plans from treasury stock. On December 31, 2014, in addition to the shares reserved for issuance upon the exercise of outstanding stock options, approximately 13 million shares have been authorized for stock options and restricted stock that may be granted in the future.
	Stock-based Compensation Expense. Stock-based compensation expense is included in G&A expenses. The following table details the components of stock-based compensation expense recognized in net earnings (loss) in each of the past three years:
	Year Ended December 31	2014				2013				2012
	Stock options	$	38			$	48			$	57
	Restricted stock	45				30				17
	Total stock-based compensation expense, net of tax	$	83			$	78			$	74
	Stock Options. We recognize compensation expense related to stock options on a straight-line basis over the vesting period of the awards, which is generally two years. We estimate the fair value of stock options on the date of grant using the Black-Scholes option pricing model with the following assumptions for each of the past three years:
	Year Ended December 31	2014			2013			2012
	Expected volatility	19.4-20.8%			21.6-27.3%			27.9-31.3%
	Weighted average expected volatility	20.2	%		23.5	%		30.7	%
	Expected term (in months)	43/53			43/53			43/53
	Risk-free interest rate	1.1-1.4%			0.5-1.0%			0.6-0.8%
	Expected dividend yield	2.5	%		3	%		2.7	%
	We determine the above assumptions based on the following:
	•	Expected volatility is based on the historical volatility of our common stock over a period equal to the expected term of the option.
	•	Expected term is based on historical option exercise data. Based on this data, we have estimated different expected terms and determined a separate fair value for options granted for two employee populations.
	•	Risk-free interest rate is the yield on a U.S. Treasury zero-coupon issue with a remaining term equal to the expected term of the option at the grant date.
	•	Expected dividend yield is based on our historical dividend yield.
	The resulting weighted average fair value per stock option granted was $13.99 in 2014, $8.90 in 2013 and $13.23 in 2012. Stock option expense reduced pretax operating earnings (and on a per-share basis) by $59 ($0.11) in 2014, $74 ($0.14) in 2013 and $88 ($0.16) in 2012. Compensation expense for stock options is reported as a Corporate expense for segment reporting purposes (see Note Q). On December 31, 2014, we had $42 of unrecognized compensation cost related to stock options, which is expected to be recognized over a weighted average period of one year.
	A summary of stock option activity during 2014 follows:
		Shares Under Option			Weighted Average
					Exercise Price Per Share
	Outstanding on December 31, 2013	17,638,111			$	69.99
	Granted	4,552,200			112.43
	Exercised	(7,698,035	)		70.36
	Forfeited/canceled	(465,750	)		74.93
	Outstanding on December 31, 2014	14,026,526			$	83.4
	Vested and expected to vest on December 31, 2014	13,909,869			$	83.22
	Exercisable on December 31, 2014	6,182,739			$	71.06
	Summary information with respect to our stock options’ intrinsic value and remaining contractual term on December 31, 2014, follows:
		Weighted Average Remaining		Aggregate Intrinsic
		Contractual Term (in years)		Value
	Outstanding	4.8		$	761
	Vested and expected to vest	4.8		757
	Exercisable	3.8		412
	In the table above, intrinsic value is calculated as the excess, if any, between the market price of our stock on the last trading day of the year and the exercise price of the options. For stock options exercised, intrinsic value is calculated as the difference between the market price on the date of exercise and the exercise price. The total intrinsic value of stock options exercised was $340 in 2014, $154 in 2013 and $112 in 2012. We received cash from the exercise of stock options of $547 in 2014, $583 in 2013 and $146 in 2012.
	Restricted Stock/Restricted Stock Units. We determine the fair value of restricted stock and RSUs as the average of the high and low market prices of our stock on the date of grant. We generally recognize compensation expense related to restricted stock and RSUs on a straight-line basis over the period during which the restriction lapses, which is generally four years.
	Compensation expense related to restricted stock and RSUs reduced pretax operating earnings (and on a per-share basis) by $69 ($0.13) in 2014, $46 ($0.09) in 2013 and $26 ($0.05) in 2012. On December 31, 2014, we had $32 of unrecognized compensation cost related to restricted stock and RSUs, which is expected to be recognized over a weighted average period of 2.2 years.
	A summary of restricted stock and RSU activity during 2014 follows:
		Shares/			Weighted Average
		Share-Equivalent Units			Grant-Date Fair Value Per Share
	Nonvested at December 31, 2013	2,507,397			$	71.11
	Granted	753,250			112.42
	Vested	(492,714	)		73.48
	Forfeited	(27,756	)		86.23
	Nonvested at December 31, 2014	2,740,177			$	78.83
	The total fair value of vesting shares was $47 in 2014, $63 in 2013 and $28 in 2012.

Compensation and Retirement Disclosure [Abstract]
Retirement Plans	RETIREMENT PLANS
	We provide defined-contribution benefits to eligible employees, as well as some remaining defined-benefit pension and other post-retirement benefits.
	Retirement Plan Summary Information
	Defined-contribution Benefits. We provide eligible employees the opportunity to participate in defined-contribution savings plans (commonly known as 401(k) plans), which permit contributions on a before-tax and after-tax basis. Generally, salaried employees and certain hourly employees are eligible to participate in the plans. Under most plans, the employee may contribute to various investment alternatives, including investment in our common stock. In some of these plans, we match a portion of the employees’ contributions. Our contributions to these plans totaled $238 in 2014, $204 in 2013 and $201 in 2012. The defined-contribution plans held approximately 25 million and 27 million shares of our common stock, representing approximately 7 percent and 8 percent of our outstanding shares on December 31, 2014 and 2013, respectively.
	Pension Benefits. We have six noncontributory and six contributory trusteed, qualified defined-benefit pension plans covering eligible government business employees, and two noncontributory and four contributory plans covering eligible commercial business employees, including some employees of our international operations. The primary factors affecting the benefits earned by participants in our pension plans are employees’ years of service and compensation levels. Our primary government pension plan, which comprises the majority of our unfunded obligation, was closed to new salaried participants on January 1, 2007. Additionally, we made changes to this plan for certain participants effective in 2014 that limit or cease the benefits that accrue for future service.
	We also sponsor one funded and several unfunded non-qualified supplemental executive plans, which provide participants with additional benefits, including excess benefits over limits imposed on qualified plans by federal tax law.
	Other Post-retirement Benefits. We maintain plans that provide post-retirement healthcare and life insurance coverage for certain employees and retirees. These benefits vary by employment status, age, service and salary level at retirement. The coverage provided and the extent to which the retirees share in the cost of the program vary throughout the company. The plans provide health and life insurance benefits only to those employees who retire directly from our service and not to those who terminate service prior to eligibility for retirement.
	Contributions and Benefit Payments
	It is our policy to fund our defined-benefit retirement plans in a manner that optimizes the tax deductibility and contract recovery of contributions, considered within our capital deployment framework. Therefore, we may make discretionary contributions in addition to the required contributions determined in accordance with IRS regulations. We contributed $513 to our pension plans in 2014 and expect to contribute approximately $185 to our pension plans in 2015.
	We maintain several tax-advantaged accounts, primarily Voluntary Employees’ Beneficiary Association (VEBA) trusts, to fund the obligations for some of our post-retirement benefit plans. For non-funded plans, claims are paid as received.
	We expect the following benefits to be paid from our retirement plans over the next 10 years:
		Pension				Other Post-retirement
		Benefits				Benefits
	2015	$	538			$	70
	2016	563				69
	2017	589				69
	2018	616				68
	2019	644				68
	2020-2024	3,680				337
	Government Contract Considerations
	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 G 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.
	Defined-benefit Retirement Plan Summary Financial Information
	Estimating retirement plan assets, liabilities and costs requires the extensive use of actuarial assumptions. These include the long-term rate of return on plan assets, the interest rate used to discount projected benefit payments, healthcare cost trend rates and future salary increases. Given the long-term nature of the assumptions being made, actual outcomes can and often do differ from these estimates.
	Our annual benefit cost consists of three primary elements: the cost of benefits earned by employees for services rendered during the year, an interest charge on our plan liabilities and an assumed return on our plan assets for the year. The annual cost also includes gains and losses resulting from changes in actuarial assumptions, differences between the actual and assumed long-term rate of return on assets and gains and losses resulting from changes we make to plan benefit terms.
	We recognize an asset or liability on the Consolidated Balance Sheets equal to the funded status of each of our defined-benefit retirement plans. The funded status is the difference between the fair value of the plan’s assets and its benefit obligation. Changes in plan assets and liabilities due to differences between actuarial assumptions and the actual results of the plan are deferred in OCL rather than charged to earnings. These differences are then amortized over future years as a component of our annual benefit cost. We amortize actuarial differences under qualified plans on a straight-line basis over the average remaining service period of eligible employees. We recognize the difference between the actual and expected return on plan assets for qualified plans over five years. The deferral of these differences reduces the volatility of our annual benefit cost that can result either from year-to-year changes in the assumptions or from actual results that are not necessarily representative of the long-term financial position of these plans. We recognize differences under nonqualified plans immediately.
	Our annual pension and other post-retirement benefit costs consisted of the following:
		Pension Benefits
	Year Ended December 31	2014				2013				2012
	Service cost	$	186			$	298			$	266

A pension plan’s funded status is the difference between the plan’s assets and its projected benefit obligation (PBO). The PBO is the present value of future benefits attributed to employee services rendered to date, including assumptions about future compensation levels. A pension plan’s accumulated benefit obligation (ABO) is the present value of future benefits attributed to employee services rendered to date, excluding assumptions about future compensation levels. The ABO for all defined-benefit pension plans was $12.8 billion and $10.6 billion on December 31, 2014 and 2013, respectively. On December 31, 2014 and 2013, some of our pension plans had an ABO that exceeded the plans’ assets. Summary information for those plans follows:
31-Dec	2014				2013
PBO	$	(12,797	)		$	(10,627	)
ABO	(12,363		)		(10,275		)
Fair value of plan assets	8,578				7,988
Retirement Plan Assumptions
We calculate the plan assets and liabilities for a given year and the net periodic benefit cost for the subsequent year using assumptions determined as of December 31 of the year in question.
The following table summarizes the weighted average assumptions used to determine our benefit obligations:
Assumptions on December 31	2014			2013
Pension Benefits
Discount rate	4.1	%		4.95	%
Rate of increase in compensation levels	3.43	%		3.7	%
Other Post-retirement Benefits
Discount rate	4.03	%		4.74	%
Healthcare cost trend rate:
Trend rate for next year	7	%		8	%
Ultimate trend rate	5	%		5	%
Year rate reaches ultimate trend rate	2024			2019
The following table summarizes the weighted average assumptions used to determine our net periodic benefit costs:
Assumptions for Year Ended December 31	2014			2013			2012
Pension Benefits
Discount rate	4.95	%		4.22	%		5.22	%
Expected long-term rate of return on assets	8.16	%		8.14	%		8.24	%
Rate of increase in compensation levels	3.78	%		3.79	%		3.77	%
Other Post-retirement Benefits
Discount rate	4.74	%		3.97	%		5.13	%
Expected long-term rate of return on assets	8.03	%		8.03	%		8.03	%
We base the discount rate on a current yield curve developed from a portfolio of high-quality fixed-income investments with maturities consistent with the projected benefit payout period. We determine the long-term rate of return on assets based on consideration of historical and forward-looking returns and the current and expected asset allocation strategy.
In 2014, we adopted updated mortality tables published by the Society of Actuaries that predict increasing life expectancies in the United States. Additionally, we updated several other assumptions to align them with historical experience, including rates of retirement and cost of living increases. The impact of these changes was a net increase of $566 and $28 in the benefit obligations of our pension and other post-retirement benefit plans, respectively, on December 31, 2014.
Retirement plan assumptions are based on our best judgment, including consideration of current and future market conditions. Changes in these estimates impact future pension and post-retirement benefit costs. As discussed above, we defer recognition of the cumulative benefit cost for our government plans in excess of costs allocable to contracts to provide a better matching of revenues and expenses. Therefore, the impact of annual changes in financial reporting assumptions on the cost for these plans does not affect our operating results either positively or negatively. For our domestic pension plans that represent the majority of our total obligation, the following hypothetical changes in the discount rate and expected long-term rate of return on plan assets would have had the following impact in 2014:
	Increase				Decrease
	25 basis points				25 basis points
Increase (decrease) to net pension cost from:
Change in discount rate	$	(29	)		$	30
Change in long-term rate of return on plan assets	(18		)		18
A 25-basis-point change in these assumed rates would not have had a measurable impact on the benefit cost for our other post-retirement plans in 2014. For our healthcare plans, the effect of a 1 percentage point increase or decrease in the assumed healthcare cost trend rate on the net periodic benefit cost is $6 and ($5), respectively, and the effect on the accumulated post-retirement benefit obligation is $94 and ($75), respectively.
Plan Assets
A committee of our board of directors is responsible for the strategic oversight of our defined-benefit retirement plan assets held in trust. Management reports to the committee on a regular basis and is responsible for overseeing all investment decisions related to defined-benefit retirement plan assets made by a third-party investment manager in compliance with the company’s policies.
Our investment policy endeavors to strike the appropriate balance among capital preservation, asset growth and current income. The objective of our investment policy is to generate future returns consistent with our assumed long-term rate of return used to determine our benefit obligations and net periodic benefit costs. Target allocation percentages vary over time depending on the perceived risk and return potential of various asset classes and market conditions. At the end of 2014, our asset allocation policy ranges were:
Equities	48 - 68%
Fixed income	20 - 48%
Cash	0 - 5%
Other asset classes	0 - 16%
More than 90 percent of our pension plan assets are held in a single trust for our primary U.S. government and commercial pension plans. On December 31, 2014, the trust was invested largely in publicly traded equities and fixed-income securities, but may invest in other asset classes in the future consistent with our investment policy. Our investments in equity assets include U.S. and international securities and equity funds as well as futures contracts on U.S. equity indices. Our investments in fixed-income assets include U.S. Treasury and U.S. agency securities, corporate bonds, mortgage-backed securities, futures contracts and international securities. Our investment policy allows the use of derivative instruments when appropriate to reduce anticipated asset volatility, to gain exposure to an asset class or to adjust the duration of fixed-income assets.
Assets for our non-U.S. pension plans are held in trusts in the countries in which the related operations reside. Our non-U.S. operations maintain investment policies for their individual plans based on country-specific regulations. The non-U.S. plan assets are primarily invested in commingled funds comprised of non-U.S. and U.S. equities and fixed-income securities.
We hold assets in VEBA trusts for some of our other post-retirement plans. These assets are generally invested in equities, corporate bonds and equity-based mutual funds. Our asset allocation strategy for the VEBA trusts considers potential fluctuations in our post-retirement liability, the taxable nature of certain VEBA trusts, tax deduction limits on contributions and the regulatory environment.
Our retirement plan assets are reported at fair value. See Note D for a discussion of the hierarchy for determining fair value. Our Level 1 assets include investments in publicly traded equity securities and commingled funds. These securities (and the underlying investments of the funds) are actively traded and valued using quoted prices for identical securities from the market exchanges. Our Level 2 assets consist of fixed-income securities and commingled funds that are not actively traded or whose underlying investments are valued using observable marketplace inputs. The fair value of plan assets invested in fixed-income securities is generally determined using valuation models that use observable inputs such as interest rates, bond yields, low-volume market quotes and quoted prices for similar assets. Our plan assets that are invested in commingled funds are valued using a unit price or net asset value (NAV) that is based on the underlying investments of the fund. We had minimal Level 3 plan assets on December 31, 2014. These investments include real estate and hedge funds, insurance deposit contracts and direct private equity investments.
The fair value of our pension plan assets by investment category and the corresponding level within the fair value hierarchy were as follows:

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; communications 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)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Basis of Consolidation and Classification	Basis of Consolidation and Classification. The 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 Consolidated Financial Statements.
	Consistent with defense industry practice, we classify assets and liabilities related to long-term 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.
Use of Estimates	Use of Estimates. The nature of our business requires that we make a number of estimates and assumptions in accordance with U.S. generally accepted accounting principles (GAAP). These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. We base our estimates on historical experience, currently available information and various other assumptions that we believe are reasonable under the circumstances. Actual results could differ from these estimates.
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 generally measure progress toward completion on contracts in our defense business based on the proportion of costs incurred to date relative to total estimated costs at completion. For our contracts for the manufacture of business-jet aircraft, we record revenue at two contractual milestones: when green aircraft are delivered to and accepted by the customer and when the customer accepts final delivery of the fully outfitted aircraft.
	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 $184 ($0.35) in 2014, $351 ($0.65) in 2013 and $180 ($0.33) in 2012. The 2013 impact of changes in estimate was higher as a result of numerous programs that neared completion in the Combat Systems group. No revisions on any one contract were material to our Consolidated Financial Statements in 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. ASU 2014-09 is effective in the first quarter of 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We have not yet selected a transition method nor have we determined the effect of the standard on our Consolidated Financial Statements.
	The required adoption of the ASU in 2017 will preclude our use of the reallocation method of recognizing revisions in estimated profit on contracts discussed previously. 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. In 2014, we entered into an agreement to sell our axle business in the Combat Systems group and recognized a $146 loss, net of tax (the sale was completed in January 2015). The financial statements have been restated to reflect the results of operations of this business in discontinued operations with the revenues of the business eliminated, and the net loss reported separately below earnings from continuing operations.
	In 2013, we recognized a $129 loss, net of tax, from the settlement of our litigation with the U.S. Navy related to the terminated A-12 contract in the company’s discontinued tactical military aircraft business. Under the terms of the settlement agreement, the Navy received a $198 credit that will be utilized over several years as we render design and construction services on the DDG-1000 program. Net cash from discontinued operations on the Consolidated Statements of Cash Flows primarily represents activity associated with the A-12 settlement and related work on the DDG-1000 program.
Research and Development Expenses	Research and Development Expenses. Company-sponsored research and development (R&D) expenses, including product development costs, were $358 in 2014, $310 in 2013 and $374 in 2012. R&D expenses are included in operating costs and expenses in the Consolidated Statements of Earnings (Loss) in the period in which they are incurred. Customer-sponsored R&D expenses are charged directly to the related contracts.
	The Aerospace group has cost-sharing arrangements with some of its suppliers that enhance the group’s internal development capabilities and offset a portion of the financial cost associated with the group’s product development efforts. These arrangements explicitly state that supplier contributions are for reimbursements of costs we incur in the development of new aircraft models and technologies, and we retain substantial rights in the products developed under these arrangements. We record amounts received from these cost-sharing arrangements as a reduction of R&D expenses. We have no obligation to refund any amounts received under the agreements regardless of the outcome of the development efforts. Under the typical terms of an agreement, payments received from suppliers for their share of the costs are based on milestones and are recognized as received.
Interest, Net	Interest, Net. Net interest expense consisted of the following:
	Year Ended December 31	2014			2013			2012
	Interest expense	$	103		$	103		$	168
	Interest income	(17		)	(17		)	(12		)
	Interest expense, net	$	86		$	86		$	156
	Interest payments	$	94		$	94		$	186
Cash And Equivalents And Investments In Debt And Equity Securities	Cash and Equivalents and Investments in Debt and Equity Securities. We consider securities with a maturity of three months or less to be cash equivalents. Our investments in other securities (see Note D) are included in other current and noncurrent assets on the Consolidated Balance Sheets. We report our held-to-maturity securities at amortized cost. We report our available-for-sale securities at fair value. Changes in the fair value of available-for-sale securities are recognized as a component of other comprehensive income (loss) in the Consolidated Statements of Comprehensive Income (Loss). We had no trading securities on December 31, 2014 or 2013.
	Net (purchases) proceeds of other securities were ($497) in 2014, including the purchase of $500 of held-to-maturity securities, ($22) in 2013 and $219 in 2012. Net proceeds in 2012 include $224 and $211 of maturities and sales of held-to-maturity securities, respectively, included in other investing activities on the Consolidated Statements of Cash Flows.
Long-lived Assets and Goodwill	Long-lived Assets and Goodwill. We review long-lived assets, including intangible assets subject to amortization, for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. We assess the recoverability of the carrying value of assets held for use based on a review of undiscounted projected cash flows. Impairment losses, where identified, are measured as the excess of the carrying value of the long-lived asset over its fair value as determined by discounted projected cash flows.
	We review goodwill for impairment annually or when circumstances indicate that an impairment is more likely than not. Goodwill represents the purchase price paid in excess of the fair value of net tangible and intangible assets acquired. The test for goodwill impairment is a two-step process to first identify potential goodwill impairment for each reporting unit and then, if necessary, measure the amount of the impairment loss. Our reporting units are consistent with our business groups in Note Q. For a summary of our goodwill by reporting unit, see Note B.
Subsequent Events	Subsequent Events. In January 2015, we repaid $500 of fixed-rate notes on their scheduled maturity date with the proceeds from maturing marketable securities.
	We have evaluated other material events and transactions that have occurred after December 31, 2014, and concluded that none have occurred that require an adjustment to or disclosure in the Consolidated Financial Statements.
Tax Uncertainties	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 believe we are entitled to interest under the Internal Revenue Code resulting from the completion of the A-12 contract triggered by the settlement of the associated litigation. The interest would be recognized when the amount is determined to be realizable, likely upon finalization of our 2014 consolidated federal corporate income tax return. See Note A to the Consolidated Financial Statements for further discussion of the A-12 settlement.
	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 December 31, 2014, 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.

Basic and diluted weighted average shares outstanding	Basic and diluted weighted average shares outstanding were as follows (in thousands):
	Year Ended December 31	2014	2013	2012
	Basic weighted average shares outstanding	335,192	350,714	353,346
	Dilutive effect of stock options and restricted stock/RSUs*	6,139	2,785	—
	Diluted weighted average shares outstanding	341,331	353,499	353,346
	* 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 year and therefore the effect of including these options would be antidilutive: 2014 - 3,683; 2013 - 8,246 and 2012 - 23,672. Additionally, because of the net loss in 2012, 2,353 otherwise dilutive stock options and restricted stock/RSUs were not included in the calculation of diluted EPS. The inclusion of these dilutive stock options and restricted stock/RSUs would have improved the diluted loss per share. For this reason, diluted EPS in 2012 was calculated using the same number of weighted average shares as basic EPS.

Antidilutive Securities Excluded from Computation of Earnings Per Share [Line Items]
Antidilutive outstanding options excluded from computation of earnings per share	3,683		8,246		23,672
[1]	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 year and therefore the effect of including these options would be antidilutive: 2014 - 3,683; 2013 - 8,246 and 2012 - 23,672. Additionally, because of the net loss in 2012, 2,353 otherwise dilutive stock options and restricted stock/RSUs were not included in the calculation of diluted EPS. The inclusion of these dilutive stock options and restricted stock/RSUs would have improved the diluted loss per share. For this reason, diluted EPS in 2012 was calculated using the same number of weighted average shares as basic EPS.
