Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	DESCRIPTION OF BUSINESS Huntington Ingalls Industries, Inc. ("HII" or the "Company") is an all-domain defense and technologies partner, recognized worldwide as America’s largest shipbuilder. HII is organized into three reportable segments: Ingalls Shipbuilding ("Ingalls"), Newport News Shipbuilding ("Newport News"), and Mission Technologies (formerly named Technical Solutions). For more than a century, the Company's Ingalls segment in Mississippi and Newport News segment in Virginia have built more ships in more ship classes than any other U.S. naval shipbuilder. The Mission Technologies segment delivers high-value engineering and technology solutions to enable multi-domain distributed operations in the government and commercial services markets. HII conducts most of its business with the U.S. Government, primarily the Department of Defense ("DoD"). As prime contractor, principal subcontractor, team member, or partner, the Company participates in many high-priority U.S. defense programs. Through its Ingalls segment, HII is a builder of amphibious assault and expeditionary warfare ships for the U.S. Navy, the sole builder of National Security Cutters for the U.S. Coast Guard, and one of only two companies that builds the Navy's current fleet of Arleigh Burke class (DDG 51) destroyers. Through its Newport News segment, HII is the nation's sole designer, builder, and refueler of nuclear-powered aircraft carriers, and one of only two companies currently designing and building nuclear-powered submarines for the U.S. Navy. The Mission Technologies segment provides a wide range of services and products, including C5ISR systems and operations; the application of Artificial Intelligence and machine learning to battlefield decisions; defensive and offensive cyberspace strategies and electronic warfare; unmanned autonomous systems; live, virtual, and constructive solutions; platform modernization; and critical nuclear operations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION Principles of Consolidation - The unaudited condensed consolidated financial statements of HII and its subsidiaries have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and the instructions to Form 10-Q promulgated by the Securities and Exchange Commission ("SEC"). All intercompany transactions and balances are eliminated in consolidation. For classification of current assets and liabilities related to its long-term production contracts, the Company uses the duration of these contracts as its operating cycle, which is generally longer than one year. These unaudited condensed consolidated financial statements include all adjustments of a normal recurring nature considered necessary by management for a fair presentation of the unaudited condensed consolidated financial position, results of operations, and cash flows and should be read in conjunction with the Company's audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2021. The quarterly information is labeled using a calendar convention; that is, first quarter is consistently labeled as ending on March 31, second quarter as ending on June 30, and third quarter as ending on September 30. It is management's long-standing practice to establish interim closing dates using a "fiscal" calendar, which requires the businesses to close their books on a Friday near these quarter-end dates in order to normalize the potentially disruptive effects of quarterly closings on business processes. The effects of this practice only exist for interim periods within a reporting year. Accounting Estimates - The preparation of the Company's unaudited condensed consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Estimates have been prepared on the basis of the most current and best available information, and actual results could differ materially from those estimates. Fair Value of Financial Instruments - Except for the Company's long-term debt, the carrying amounts of the Company's financial instruments are recorded at historical cost approximate fair value due to the short-term nature of the instruments and low credit risk associated with the respective counterparties. The Company maintains multiple grantor trusts to fund certain non-qualified pension plans. These trusts were valued at $201 million and $220 million as of June 30, 2022, and December 31, 2021, respectively, and are presented within miscellaneous other assets within the unaudited condensed consolidated statements of financial position. These trusts consist primarily of investments in marketable securities, which are held at fair value within Level 1 of the fair value hierarchy. The estimated fair values of the Company's total long-term debt as of June 30, 2022, and December 31, 2021, were $2,954 million and $3,449 million, respectively. The fair values of the Company's long-term debt were calculated based on recent trades of the Company's debt instruments in inactive markets, which fall within Level 2 under the fair value hierarchy. Debt Prepayment - As of June 30, 2022, $225 million of the Company's Term Loan due August 19, 2024 has been prepaid, with a remaining balance of $425 million.

Acquisitions and Divestitures [Abstract]
Acquisitions	ACQUISITIONS On August 19, 2021, the Company acquired all of the outstanding common stock of Alion Holding Corp., the parent company of Alion Science and Technology Corporation (“Alion”), a technology-driven solutions provider. The Company accounted for the transaction as a business combination using the acquisition method of accounting in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 805 Business Combinations . The preliminary purchase price was $1.79 billion, including $148 million of cash received in the acquisition. In connection with the acquisition, the Company originally recorded $1,024 million of goodwill, which included the value of Alion's workforce, and $720 million of intangible assets related to customer relationships and existing contract backlog. The goodwill is attributable to operational synergies and growth opportunities and was allocated to the Company's Mission Technologies segment. For the six months ended June 30, 2022, the Company recorded an increase to goodwill of $6 million, resulting from an adjustment to contingent liabilities for potential information reporting penalties. None of the goodwill resulting from this acquisition is expected to be amortizable for tax purposes. Alion provides advanced engineering and research and development services in the areas of intelligence, surveillance, and reconnaissance, military training and simulation, cyber, data analytics, and other next-generation technology based solutions to the DoD and intelligence community customers, with the U.S. Navy representing about one-third of current annual revenues. Pro Forma Financial Information The following unaudited consolidated pro forma summary has been prepared by adjusting the Company's historical data to give effect to the acquisition of Alion as if it had occurred on January 1, 2021. Three Months Ended Six Months Ended ($ in millions, except per share amounts) 2022 Pro Forma 2021 2022 Pro Forma 2021 Sales and service revenues $ 2,662 $ 2,562 $ 5,238 $ 5,155 Net earnings $ 178 $ 121 $ 318 $ 265 Basic earnings per share $ 4.44 $ 3.00 $ 7.93 $ 6.58 Diluted earnings per share $ 4.44 $ 3.00 $ 7.93 $ 6.58 These unaudited pro forma results include adjustments associated with the acquisition, such as the amortization of acquired intangible assets and interest expense on debt financing. The unaudited consolidated pro forma financial information was prepared in accordance with GAAP and is not necessarily indicative of the results of operations that would have occurred if the acquisition had been completed on the date indicated, nor is it indicative of the future operating results of the Company.

Disaggregation of Revenue [Abstract]
Revenue from Contract with Customer	REVENUE Disaggregation of Revenue The Company's contracts with customers typically fall into one of four categories: firm fixed-price, fixed-price incentive, cost-type, and time and materials. • Firm Fixed-Price Contracts - A firm fixed-price contract is a contract in which the specified scope of work is agreed to for a price that is predetermined by bid or negotiation and not generally subject to adjustment regardless of costs incurred by the contractor. • Fixed-Price Incentive Contracts - Fixed-price incentive contracts provide for reimbursement of the contractor's allowable costs, but are subject to a cost-share limit that affects profitability. Fixed-price incentive contracts effectively become firm fixed-price contracts once the cost-share limit is reached. • Cost-Type Contracts - Cost-type contracts provide for reimbursement of the contractor's allowable costs plus a fee that represents profit. Cost-type contracts generally require that the contractor use its reasonable efforts to accomplish the scope of the work within some specified time and some stated dollar limitation. • Time and Materials - Time and materials contracts specify a fixed hourly billing rate for each direct labor hour expended and reimbursement for allowable material costs and expenses.

Income Taxes

Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company's earnings are primarily domestic, and its effective income tax rates on earnings from operations for the three months ended June 30, 2022 and 2021, were 19.8% and 19.9%, respectively. For the six months ended June 30, 2022 and 2021, the Company's effective income tax rates on earnings from operations were 20.1% and 17.1%, respectively. The effective tax rate for the three months ended June 30, 2022, was generally flat compared to the prior year. The higher effective tax rate for the six months ended June 30, 2022, was primarily attributable to a tax loss associated with the sale of the Company’s oil and gas business recorded in 2021. For the three months ended June 30, 2022, the Company’s effective tax rate differed from the federal statutory corporate income tax rate primarily as a result of research and development tax credits. For the six months ended June 30, 2022, the Company’s effective tax rate did not differ materially from the federal statutory corporate income tax rate of 21%. For the three months ended June 30, 2021, the Company’s effective tax rate differed from the federal statutory tax rate primarily as a result of research and development tax credits. For the six months ended June 30, 2021, the Company’s effective tax rate differed from the federal statutory tax rate primarily as a result of a tax loss associated with the sale of its oil and gas business. The Company's unrecognized tax benefits increased by $3 million and $5 million during the three and six months ended June 30, 2022, respectively. As of June 30, 2022, the estimated amounts of the Company's unrecognized tax benefits, excluding interest and penalties, were liabilities of $86 million. Assuming a sustainment of these tax positions, a reversal of $65 million of the accrued amounts would favorably affect the Company's effective federal income tax rate in future periods. The Company recognizes interest and penalties related to unrecognized tax benefits as income tax expense. For the three and six months ended June 30, 2022, interest resulting from the unrecognized tax benefits noted above increased income tax expense by less than $1 million. Non-current state income taxes include deferred state income taxes, which reflect the change in deferred state tax assets and liabilities, and the tax expense or benefit associated with changes in unrecognized state tax benefits in the relevant period. These amounts are recorded within operating income. Current period state income tax expense is charged to contract costs and included in cost of sales and service revenues in segment operating income.

Investigations, Claims, and Lit

Investigations, Claims, and Litigation	6 Months Ended
	Jun. 30, 2022
Investigations, Claims, And Litigation [Abstract]
Investigations, Claims, And Litigation	INVESTIGATIONS, CLAIMS, AND LITIGATION The Company is involved in legal proceedings before various courts and administrative agencies, and is periodically subject to government examinations, inquiries and investigations. Pursuant to FASB ASC 450 Contingencies, the Company has accrued for losses associated with investigations, claims, and litigation when, and to the extent that, loss amounts related to the investigations, claims, and litigation are probable and can be reasonably estimated. The actual losses that might be incurred to resolve such investigations, claims, and litigation may be higher or lower than the amounts accrued. The Company has, in certain cases, provided disclosure regarding certain matters for which the Company believes at this time that the likelihood of material loss is remote. False Claims Act Complaint - In 2016, the Company was made aware that it is a defendant in a qui tam False Claims Act lawsuit pending in the U.S. District Court for the Middle District of Florida related to the Company’s purchases of allegedly non-conforming parts from a supplier for use in connection with U.S. Government contracts. In August 2019, the Department of Justice (“DoJ”) declined to intervene in the lawsuit, and the lawsuit was unsealed. The court dismissed the complaint in September 2021, and the plaintiff has appealed the dismissal to the United States Court of Appeals for the 11th Circuit. Insurance Claims - In September 2020, the Company filed a complaint against 32 reinsurers in the Superior Court, State of Vermont, Franklin Unit, seeking a judgment declaring that the Company's business interruption and other losses associated with COVID-19 are covered by the Company's property insurance program. The Company also initiated arbitration proceedings against six other reinsurers seeking similar relief. In July 2021, the Vermont court granted the reinsurers’ motion for judgment on the pleadings, and the Company has appealed the decision to the Vermont Supreme Court. Although the Company still believes its position is well-founded, no assurances can be provided regarding the ultimate resolution of this matter. In September 2021, the Company filed a complaint in the Superior Court of Delaware, seeking a judgment against certain insurers for breach of contract and breach of the implied covenant of good faith and fair dealing under three representations and warranties insurance policies purchased in connection with the Company’s acquisition of Hydroid. The policies insure the Company against losses relating to the seller’s breach of certain representations and warranties in the Hydroid acquisition agreement. The coverage limit under the insurance policies is $70 million, and the Company believes it has incurred losses equal to at least that amount as a result of breaches of the acquisition agreement. No assurances can be provided regarding the ultimate resolution of this matter. U.S. Government Investigations and Claims - Departments and agencies of the U.S. Government have the authority to investigate various transactions and operations of the Company, and the results of such investigations may lead to administrative, civil, or criminal proceedings, the ultimate outcome of which could be fines, penalties, repayments or compensatory, treble, or other damages. U.S. Government regulations provide that certain findings against a contractor may also lead to suspension or debarment from future U.S. Government contracts or the loss of export privileges. Any suspension or debarment would have a material effect on the Company because of its reliance on government contracts. Asbestos Related Claims - HII and its predecessors-in-interest are defendants in a longstanding series of cases that have been and continue to be filed in various jurisdictions around the country, wherein former and current employees and various third parties allege exposure to asbestos containing materials while on or associated with HII premises or while working on vessels constructed or repaired by HII. In some instances, partial or full insurance coverage is available for the Company's liabilities. The costs to resolve cases during the six months ended June 30, 2022 and 2021, were immaterial individually and in the aggregate. The Company’s estimate of asbestos-related liabilities is subject to uncertainty because liabilities are influenced by many variables that are inherently difficult to predict. Although the Company believes the ultimate resolution of current cases will not have a material effect on its consolidated financial position, results of operations, and cash flows, it cannot predict what new or revised claims or litigation might be asserted or what information might come to light and can, therefore, give no assurances regarding the ultimate outcome of asbestos related litigation. Other Litigation - The Company and its predecessor-in-interest have been in litigation with the Bolivarian Republic of Venezuela (the "Republic") since 2002 over a contract for the repair, refurbishment, and modernization at Ingalls of two foreign-built frigates. Following an arbitration proceeding between the parties, in February 2018, the arbitral tribunal awarded the Company approximately $151 million on its claims and awarded the Republic approximately $22 million on its counterclaims. The Company is seeking to enforce and execute upon the award in multiple jurisdictions. No assurances can be provided regarding the ultimate resolution of this matter. The Company is party to various other claims, legal proceedings, and investigations that arise in the ordinary course of business, including U.S. Government investigations that could result in administrative, civil, or criminal proceedings involving the Company. The Company is a contractor with the U.S. Government, and such proceedings can therefore include False Claims Act allegations against the Company. Although the Company believes that the resolution of these other claims, legal proceedings, and investigations will not have a material effect on its consolidated financial position, results of operations, and cash flows, the Company cannot predict what new or revised claims or litigation might be asserted or what information might come to light and can, therefore, give no assurances regarding the ultimate outcome of these matters.

Commitments and Contingencies

Commitments and Contingencies	6 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Contract Performance Contingencies - Contract profit margins may include estimates of revenues for matters on which the customer and the Company have not reached agreement, such as settlements in the process of negotiation, contract changes, claims, and requests for equitable adjustment for unanticipated contract costs. These estimates are based upon management's best assessment of the underlying causal events and circumstances and recognized to the extent of expected recovery based upon contractual entitlements and the probability of successful negotiation with the customer. As of June 30, 2022, amounts recognized in connection with claims and requests for equitable adjustment were not material individually or in the aggregate. Environmental Matters - The estimated cost to complete environmental remediation has been accrued when it is probable that the Company will incur such costs in the future to address environmental conditions at currently or formerly owned or leased operating facilities, or at sites where it has been named a Potentially Responsible Party by the Environmental Protection Agency or similarly designated by another environmental agency, and the related costs can be estimated by management. These accruals do not include any litigation costs related to environmental matters, nor do they include amounts recorded as asset retirement obligations. Management estimates that as of June 30, 2022, the probable estimable future cost for environmental remediation was immaterial. Although management cannot predict whether new information gained as remediation progresses or the Company incurs additional remediation obligations will materially affect the estimated liability accrued, management does not believe that future remediation expenditures will have a material effect on the Company's consolidated financial position, results of operations, and cash flows. Financial Arrangements - In the ordinary course of business, HII uses letters of credit issued by commercial banks to support certain leases, insurance policies, and contractual performance obligations, as well as surety bonds issued by insurance companies principally to support the Company's self-insured workers' compensation plans. As of June 30, 2022, the Company had $15 million in issued but undrawn letters of credit and $276 million of surety bonds outstanding. U.S. Government Claims - From time to time, the U.S. Government communicates to the Company potential claims, disallowed costs, and penalties concerning prior costs incurred by the Company with which the U.S. Government disagrees. When such preliminary findings are presented, the Company and U.S. Government representatives engage in discussions, from which the Company evaluates the merits of the claims and assesses the amounts being questioned. Although the Company believes that the resolution of any of these matters will not have a material effect on its consolidated financial position, results of operations, and cash flows, it cannot predict the ultimate outcome of these matters. Other Matters - In 1985, the Company and the U.S. Navy entered into a settlement agreement to resolve disputes associated with billing and allocating to contracts the cost of workers’ compensation self-insurance, among other matters. Consistent with the 1985 settlement agreement, the Company has not recovered cumulative billable costs resulting from the different treatment of workers' compensation costs between CAS and U.S. GAAP Financial Accounting Standards ("FAS"). Under the 1985 settlement agreement, these costs would be recovered in future periods. In December 2020, a U.S. Navy Contracting Officer issued a determination that the 1985 settlement agreement did not comply with CAS and directed the Company to develop and implement a different process to bill and allocate the cost of workers’ compensation self-insurance. In July 2022, the Contracting Officer reiterated its direction that the Company submit a cost accounting practice change from the 1985 settlement agreement for Government review and concurrence. Although the Company believes the 1985 settlement agreement is CAS-compliant and cannot be unilaterally terminated, the Company is seeking to negotiate a resolution of the matter with the Contracting Officer. In January 2022, a U.S. Navy Contracting Officer issued a written determination that the Ingalls Shipbuilding Material Management and Accounting System (“MMAS”) had three significant deficiencies (as defined in the Defense Federal Acquisition Regulation Supplement provision relating to MMASs), resulting in a 5% withhold of payments on certain invoices issued under one contract. Ingalls subsequently submitted a corrective action plan, which was approved in February 2022, and the withhold was reduced to 2%. On May 27, 2022, the Contracting Officer determined that Ingalls had corrected the significant deficiencies, and the Contracting Officer terminated the remaining 2% withhold and approved the MMAS system. Collective Bargaining Agreements - Of the Company's approximately 44,000 employees, approximately 45% are covered by a total of nine collective bargaining agreements and one site stabilization agreement. Newport News has three collective bargaining agreements covering represented employees, including one with United Steelworkers Local 8888 (Newport News) (the “USWs”), which covers approximately 50% of Newport News employees. The collective bargaining agreement with the USWs expired in November 2021, and the Company reached a tentative agreement with representatives of the USWs in February 2022. The members of the USWs bargaining unit ratified the contract in March 2022. The Company believes its relationship with its employees is satisfactory.

In March 2022, the Company concluded negotiations on one of its collective bargaining agreements, which required an amendment to one of the Company's pension plans. As a result of the amendment, the remeasurement of the plan increased the pension liability and pre-tax accumulated other comprehensive loss by approximately $97 million.

Basis of Presentation (Policies

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation	Principles of Consolidation - The unaudited condensed consolidated financial statements of HII and its subsidiaries have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and the instructions to Form 10-Q promulgated by the Securities and Exchange Commission ("SEC"). All intercompany transactions and balances are eliminated in consolidation. For classification of current assets and liabilities related to its long-term production contracts, the Company uses the duration of these contracts as its operating cycle, which is generally longer than one year. These unaudited condensed consolidated financial statements include all adjustments of a normal recurring nature considered necessary by management for a fair presentation of the unaudited condensed consolidated financial position, results of operations, and cash flows and should be read in conjunction with the Company's audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2021.
Fiscal Period Policy	The quarterly information is labeled using a calendar convention; that is, first quarter is consistently labeled as ending on March 31, second quarter as ending on June 30, and third quarter as ending on September 30. It is management's long-standing practice to establish interim closing dates using a "fiscal" calendar, which requires the businesses to close their books on a Friday near these quarter-end dates in order to normalize the potentially disruptive effects of quarterly closings on business processes. The effects of this practice only exist for interim periods within a reporting year.
Accounting Estimates	Accounting Estimates - The preparation of the Company's unaudited condensed consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Estimates have been prepared on the basis of the most current and best available information, and actual results could differ materially from those estimates.
