BASIS OF PRESENTATION	Mar. 31, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION We prepared these consolidated financial statements in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information, the instructions to Form 10-Q and Article 10 of U.S. Securities and Exchange Commission (SEC) Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, these consolidated financial statements reflect all adjustments that are of a normal recurring nature necessary for a fair presentation of our results of operations, financial condition, and cash flows for the interim periods presented. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base these estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Our actual results may differ materially from these estimates. Significant estimates inherent in the preparation of our consolidated financial statements include, but are not limited to, accounting for sales and cost recognition; postretirement benefit plans; environmental liabilities and assets for the portion of environmental costs that are probable of future recovery; evaluation of goodwill, intangible assets, investments and other assets for impairment; income taxes including deferred tax assets; fair value measurements; and contingencies. The consolidated financial statements include the accounts of subsidiaries we control and variable interest entities if we are the primary beneficiary. We eliminate intercompany balances and transactions in consolidation. We close our books and records on the last Sunday of the interim calendar quarter, which was on March 31 for the first quarter of 2024 and March 26 for the first quarter of 2023, to align our financial closing with our business processes. The consolidated financial statements and tables of financial information included herein are labeled based on that convention. This practice only affects interim periods as our fiscal year ends on December 31. The results of operations for the interim periods presented are not necessarily indicative of results to be expected for the full year or future periods. Unless otherwise noted, we present all per share amounts cited in these consolidated financial statements on a “per diluted share” basis. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2023 (2023 Form 10-K).

INFORMATION ON BUSINESS SEGMENTS	Mar. 31, 2024
Segment Reporting [Abstract]
INFORMATION ON BUSINESS SEGMENTS	INFORMATION ON BUSINESS SEGMENTS Overview We operate in four business segments: Aeronautics, Missiles and Fire Control (MFC), Rotary and Mission Systems (RMS) and Space. We organize our business segments based on the nature of products and services offered. Selected Financial Data by Business Segment Net sales and operating profit of our business segments exclude intersegment sales, cost of sales and profit as these activities are eliminated in consolidation and thus are not included in management’s evaluation of performance of each segment. Business segment operating profit includes our share of earnings or losses from equity method investees as the operating activities of the equity method investees are closely aligned with the operations of our business segments. Summary operating results for each of our business segments were as follows (in millions): Quarters Ended March 31, March 26, Net sales Aeronautics $ 6,845 $ 6,269 Missiles and Fire Control 2,993 2,388 Rotary and Mission Systems 4,088 3,510 Space 3,269 2,959 Total net sales $ 17,195 $ 15,126 Operating profit Aeronautics $ 679 $ 675 Missiles and Fire Control 311 377 Rotary and Mission Systems 430 350 Space 325 280 Total business segment operating profit 1,745 1,682 Unallocated items FAS/CAS pension operating adjustment 406 415 Intangible asset amortization expense (61) (62) Other, net (61) 2 Total unallocated items 284 355 Total consolidated operating profit $ 2,029 $ 2,037 Intersegment sales Aeronautics $ 70 $ 53 Missiles and Fire Control 202 146 Rotary and Mission Systems 586 489 Space 107 86 Total intersegment sales $ 965 $ 774 Unallocated Items Business segment operating profit excludes the FAS/CAS pension operating adjustment, a portion of corporate costs not considered allowable or allocable to contracts with the U.S. Government under the applicable U.S. Government cost accounting standards (CAS) or federal acquisition regulations (FAR), and other items not considered part of management’s evaluation of segment operating performance such as a portion of management and administration costs, legal fees and settlements, stock-based compensation expense, changes in the fair value of assets and liabilities for deferred compensation plans, retiree benefits, significant severance charges, significant asset impairments, gains or losses from divestitures, intangible asset amortization expense, and other miscellaneous corporate activities. Excluded items are included in the reconciling item “Unallocated items” between operating profit from our business segments and our consolidated operating profit. See “Note 10 - Other” for a discussion related to certain factors that may impact the comparability of net sales and operating profit of our business segments. FAS/CAS Pension Operating Adjustment Our business segments’ results of operations include pension expense only as calculated under U.S. Government Cost Accounting Standards (CAS), which we refer to as CAS pension cost. We recover CAS pension and other postretirement benefit plan cost through the pricing of our products and services on U.S. Government contracts and, therefore, recognize CAS pension cost in each of our business segment’s net sales and cost of sales. Our consolidated financial statements must present pension and other postretirement benefit plan income calculated in accordance with Financial Accounting Standards (FAS) requirements under U.S. GAAP. The operating portion of the total FAS/CAS pension adjustment represents the difference between the service cost component of FAS pension income (expense) and total CAS pension cost. The non-service FAS pension income (expense) components are included in non-service FAS pension income (expense) in our consolidated statements of earnings. As a result, to the extent that CAS pension cost exceeds the service cost component of FAS pension income (expense) we have a favorable FAS/CAS pension operating adjustment.

CONTRACT ASSETS AND LIABILITIES

CONTRACT ASSETS AND LIABILITIES	3 Months Ended
CONTRACT ASSETS AND LIABILITIES	Mar. 31, 2024
Revenue from Contract with Customer [Abstract]
CONTRACT ASSETS AND LIABILITIES	Contract assets include unbilled amounts typically resulting from sales under contracts when the percentage-of-completion cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer. Contract liabilities include advance payments and billings in excess of revenue recognized. Contract assets and contract liabilities were as follows (in millions): March 31, December 31, Contract assets $ 14,050 $ 13,183 Contract liabilities 8,745 9,190 Contract assets increased $867 million during the quarter ended March 31, 2024, due to the recognition of revenue related to the satisfaction or partial satisfaction of performance obligations during the quarter ended March 31, 2024 for which we have not yet billed our customers. There were no significant credit or impairment losses related to our contract assets during the quarters ended March 31, 2024 and March 26, 2023. Contract liabilities decreased $445 million during the quarter ended March 31, 2024, primarily due to revenue recognized in excess of payments received on these performance obligations. During the quarter ended March 31, 2024, we recognized $2.4 billion of our contract liabilities at December 31, 2023 as revenue. During the quarter ended March 26, 2023, we recognized $2.2 billion of our contract liabilities at December 31, 2022 as revenue.

INVENTORIES	Inventories consisted of the following (in millions): March 31, December 31, Materials, spares and supplies $ 640 $ 606 Work-in-process 2,443 2,338 Finished goods 195 188 Total inventories $ 3,278 $ 3,132 Costs incurred to fulfill a contract in advance of the contract being awarded are included in inventories as work-in-process if we determine that those costs relate directly to a contract or to an anticipated contract that we can specifically identify and determine that contract award is probable, the costs generate or enhance resources that will be used in satisfying performance obligations, and the costs are recoverable (referred to as pre-contract costs). These advanced procurement costs are generally incurred in order to enhance our ability to achieve schedule and certain customer milestones. Pre-contract costs that are initially capitalized in inventory are generally recognized as cost of sales consistent with the transfer of products and services to the customer upon the receipt of the anticipated contract. All other pre-contract costs, including start-up costs, are expensed as incurred. As of March 31, 2024 and December 31, 2023, $1.1 billion and $989 million of pre-contract costs (primarily the F-35 program and classified contracts at our Aeronautics business segment) were included in inventories.

The amortization of net actuarial losses or gains and prior service credits or costs in the table above, along with similar costs related to our other postretirement benefit plans ($4 million for the quarter ended March 31, 2024 and $3 million for the quarter ended March 26, 2023) were reclassified from accumulated other comprehensive loss (AOCL) and recorded as a component of FAS income for the periods presented. These costs totaled $24 million, ($19 million, net of tax) during the quarter ended March 31, 2024, and $(47) million ($(37) million, net of tax) during the quarter ended March 26, 2023. Funding Requirements The required funding of our qualified defined benefit pension plans is determined in accordance with the Employee Retirement Income Security Act of 1974 (ERISA), as amended, along with consideration of CAS and Internal Revenue Code rules. We made no contributions to our qualified defined benefit pension plans during the quarters ended March 31, 2024 and March 26, 2023.

LEGAL PROCEEDINGS AND CONTINGEN

LEGAL PROCEEDINGS AND CONTINGENCIES	Mar. 31, 2024
Commitments and Contingencies Disclosure [Abstract]
LEGAL PROCEEDINGS AND CONTINGENCIES	LEGAL PROCEEDINGS AND CONTINGENCIES Legal Proceedings We are a party to litigation and other proceedings that arise in the ordinary course of our business, including matters arising under provisions relating to the protection of the environment, and are subject to contingencies related to certain businesses we previously owned. These types of matters could result in fines, penalties, cost reimbursements or contributions, compensatory or treble damages or non-monetary sanctions or relief. We believe the probability is remote that the outcome of each of these matters, including the legal proceedings described below, will have a material adverse effect on the company as a whole, notwithstanding that the unfavorable resolution of any matter may have a material effect on our net earnings and cash flows in any particular interim reporting period. Among the factors that we consider in this assessment are the nature of existing legal proceedings and claims, the asserted or possible damages or loss contingency (if estimable), the progress of the case, existing law and precedent, the opinions or views of legal counsel and other advisers, our experience in similar cases and the experience of other companies, the facts available to us at the time of assessment and how we intend to respond to the proceeding or claim. Our assessment of these factors may change over time as individual proceedings or claims progress. Although we cannot predict the outcome of legal or other proceedings with certainty, where there is at least a reasonable possibility that a loss may have been incurred, GAAP requires us to disclose an estimate of the reasonably possible loss or range of loss or make a statement that such an estimate cannot be made. We follow a thorough process in which we seek to estimate the reasonably possible loss or range of loss, and only if we are unable to make such an estimate do we conclude and disclose that an estimate cannot be made. Accordingly, unless otherwise indicated below in our discussion of legal proceedings, a reasonably possible loss or range of loss associated with any individual legal proceeding cannot be estimated. United States of America, ex rel. Patzer; Cimma v. Sikorsky Aircraft Corp., et al. As a result of our acquisition of Sikorsky Aircraft Corporation (Sikorsky), we assumed the defense of and any potential liability for two civil False Claims Act lawsuits pending in the U.S. District Court for the Eastern District of Wisconsin. In October 2014, the U.S. Government filed a complaint in intervention in the first suit, which was brought by qui tam relator Mary Patzer, a former Derco Aerospace (Derco) employee. In May 2017, the U.S. Government filed a complaint in intervention in a second suit, which was brought by qui tam relator Peter Cimma, a former Sikorsky Support Services, Inc. (SSSI) employee. In November 2017, the Court consolidated the cases into a single action for discovery and trial. The U.S. Government alleges that Sikorsky and two of its wholly-owned subsidiaries, Derco and SSSI, violated the civil False Claims Act and the Truth in Negotiations Act in connection with a contract the U.S. Navy awarded to SSSI in June 2006 to support the Navy’s T-34 and T-44 fixed-wing turboprop training aircraft. SSSI subcontracted with Derco, primarily to procure and manage spare parts for the training aircraft. The U.S. Government contends that SSSI overbilled the Navy on the contract as the result of Derco’s use of prohibited cost-plus-percentage-of-cost (CPPC) pricing to add profit and overhead costs as a percentage of the price of the spare parts that Derco procured and then sold to SSSI. The U.S. Government also alleges that Derco’s claims to SSSI, SSSI’s claims to the Navy, and SSSI’s yearly Certificates of Final Indirect Costs from 2006 through 2012 were false and that SSSI submitted inaccurate cost or pricing data in violation of the Truth in Negotiations Act for a sole-sourced, follow-on “bridge” contract. The U.S. Government’s complaints assert common law claims for breach of contract and unjust enrichment. On November 29, 2021, the District Court granted the U.S. Government’s motion for partial summary judgment, finding that the Derco-SSSI agreement was a CPPC contract. On October 17, 2023, the District Court ruled on the parties’ cross motions for summary judgment, granting some motions and denying others. Trial on the U.S. Government’s remaining claims is scheduled for May 6, 2024. We believe that we have legal and factual defenses to the U.S. Government’s remaining claims. The U.S. Government seeks damages of approximately $52 million, subject to trebling, plus statutory penalties. Although we continue to evaluate our liability and exposure, we do not currently believe that it is probable that we will incur a material loss. If, contrary to our expectations, the U.S. Government prevails on the remaining issues in this matter and proves damages at or near $52 million and is successful in having such damages trebled, the outcome could have an adverse effect on our results of operations in the period in which a liability is recognized and on our cash flows for the period in which any damages are paid. Lockheed Martin v. Metropolitan Transportation Authority On April 24, 2009, we filed a declaratory judgment action against the New York Metropolitan Transportation Authority and its Capital Construction Company (collectively, the MTA) asking the U.S. District Court for the Southern District of New York to find that the MTA is in material breach of our agreement based on the MTA’s failure to provide access to sites where work must be performed and the customer-furnished equipment necessary to complete the contract. The MTA filed an answer and counterclaim alleging that we breached the contract and subsequently terminated the contract for alleged default. The primary damages sought by the MTA are the costs to complete the contract and potential re-procurement costs. While we are unable to estimate the cost of another contractor to complete the contract and the costs of re-procurement, we note that our contract with the MTA had a total value of $323 million, of which $241 million was paid to us, and that the MTA is seeking damages of approximately $190 million. We dispute the MTA’s allegations and are defending against them. Additionally, following an investigation, our sureties on a performance bond related to this matter, who were represented by independent counsel, concluded that the MTA’s termination of the contract was improper. Finally, our declaratory judgment action was later amended to include claims for monetary damages against the MTA of approximately $95 million. This matter was taken under submission by the District Court in December 2014, after a five-week bench trial and the filing of post-trial pleadings by the parties. We continue to await a decision from the District Court. Although this matter relates to our former Information Systems & Global Solutions (IS&GS) business, we retained responsibility for the litigation when we divested IS&GS in 2016. Environmental Matters We are involved in proceedings and potential proceedings relating to soil, sediment, surface water, and groundwater contamination, disposal of hazardous substances, and other environmental matters at several of our current or former facilities, facilities for which we may have contractual responsibility, and at third-party sites where we have been designated as a potentially responsible party (PRP). A substantial portion of environmental costs will be included in our net sales and cost of sales in future periods pursuant to U.S. Government regulations. At the time a liability is recorded for future environmental costs, we record assets for estimated future recovery considered probable through the pricing of products and services to agencies of the U.S. Government, regardless of the contract form (e.g., cost-reimbursable, fixed-price). We continually evaluate the recoverability of our assets for the portion of environmental costs that are probable of future recovery by assessing, among other factors, U.S. Government regulations, our U.S. Government business base and contract mix, and our history of receiving reimbursement of such costs. We include the portions of those environmental costs expected to be allocated to our non-U.S. government contracts, or determined not to be recoverable under U.S. Government contracts, in our cost of sales at the time the liability is established or adjusted. At March 31, 2024 and December 31, 2023, the aggregate amount of liabilities recorded relative to environmental matters was $677 million and $680 million, most of which are recorded in other noncurrent liabilities Environmental remediation activities usually span many years, which makes estimating liabilities a matter of judgment because of uncertainties with respect to assessing the extent of the contamination as well as such factors as changing remediation technologies and changing regulatory environmental standards. We are monitoring or investigating a number of former and present operating facilities for potential future remediation. We perform quarterly reviews of the status of our environmental remediation sites and the related liabilities and receivables. Additionally, in our quarterly reviews, we consider these and other factors in estimating the timing and amount of any future costs that may be required for remediation activities, and we record a liability when it is probable that a loss has occurred or will occur for a particular site and the loss can be reasonably estimated. The amount of liability recorded is based on our estimate of the costs to be incurred for remediation for that site. We do not discount the recorded liabilities, as the amount and timing of future cash payments are not fixed or cannot be reliably determined. We cannot reasonably determine the extent of our financial exposure in all cases as, although a loss may be probable or reasonably possible, in some cases it is not possible at this time to estimate the reasonably possible loss or range of loss. We project costs and recovery of costs over approximately 20 years. We also pursue claims for recovery of costs incurred or for contribution to site remediation costs against other PRPs, including the U.S. Government, and are conducting remediation activities under various consent decrees, orders, and agreements relating to soil, groundwater, sediment, or surface water contamination at certain sites of former or current operations. Under agreements related to certain sites in California, New York, United States Virgin Islands and Washington, the U.S. Government and/or a private party reimburses us an amount equal to a percentage, specific to each site, of expenditures for certain remediation activities in their capacity as PRPs under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). In addition to the proceedings and potential proceedings discussed above, potential new regulations concerning perchlorate and hexavalent chromium at the federal and state level could increase our cleanup costs. If substantially lower cleanup standards are adopted for perchlorate or for hexavalent chromium, we expect a material increase in both our estimates for environmental liabilities and the related assets for the portion of costs that are probable of future recovery. The amount that would be allocable to our non-U.S. government contracts or that is determined not to be recoverable under U.S. Government contracts would be expensed, which may have a material effect on our earnings in any particular interim reporting period. We also are evaluating the potential impact of new, existing, and contemplated requirements addressing a class of chemicals known generally as per- and polyfluoroalkyl substances (PFAS). PFAS are common and appear in products such as fire-fighting foams and stain- and stick-resistant products (e.g., Teflon, stain-resistant fabrics) and have been used in manufacturing processes. Regulations requiring very low PFAS contaminant levels in drinking water could eventually lead to increased cleanup costs at a number of our environmental remediation sites. Letters of Credit, Surety Bonds and Third-Party Guarantees We have entered into standby letters of credit and surety bonds issued on our behalf by financial institutions, and we have directly issued guarantees to third parties primarily relating to advances received from customers and the guarantee of future performance on certain contracts. Letters of credit and surety bonds generally are available for draw down in the event we do not perform. We had total outstanding letters of credit and surety bonds aggregating $2.7 billion and $2.9 billion at March 31, 2024 and December 31, 2023. Additionally, we may guarantee the contractual performance of third parties such as joint venture partners. At March 31, 2024 and December 31, 2023, third-party guarantees totaled $364 million and $1.0 billion, of which approximately 29% and 75% related to guarantees of contractual performance of joint ventures to which we currently are or previously were a party. These amounts represent our estimate of the maximum amounts we would expect to incur upon the contractual non-performance of the joint venture, joint venture partners or divested businesses. Generally, we also have cross-indemnities in place that may enable us to recover amounts that may be paid on behalf of a joint venture partner. Third-party guarantees do not include guarantees issued on behalf of subsidiaries and other consolidated entities. In determining our exposures, we evaluate the reputation, performance on contractual obligations, technical capabilities and credit quality of our current and former joint venture partners and the transferee under novation agreements all of which include a guarantee as required by the FAR. At March 31, 2024 and December 31, 2023, there were no material amounts recorded in our financial statements related to third-party guarantees or novation agreements. Other Contingencies As a U.S. Government contractor, we are subject to various audits and investigations by the U.S. Government to determine whether our operations are being conducted in accordance with applicable regulatory requirements. U.S. Government investigations of us, whether relating to government contracts or conducted for other reasons, could result in administrative, civil, or criminal liabilities, including repayments, fines or penalties being imposed upon us, suspension, proposed debarment, debarment from eligibility for future U.S. Government contracting, or suspension of export privileges. Suspension or debarment could have a material adverse effect on us because of our dependence on contracts with the U.S. Government. U.S. Government investigations often take years to complete and many result in no adverse action against us. We also provide products and services to customers outside of the U.S., which are subject to U.S. and foreign laws and regulations and foreign procurement policies and practices. Our compliance with local regulations or applicable U.S. Government regulations also may be audited or investigated. In the normal course of business, 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 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.

The fair values of mutual funds and certain other securities are determined by reference to the quoted market price per unit in active markets multiplied by the number of units held without consideration of transaction costs. The fair values of U.S. Government and certain other securities are determined using pricing models that use observable inputs (e.g., interest rates and yield curves observable at commonly quoted intervals), bids provided by brokers or dealers or quoted prices of securities with similar characteristics. The fair values of derivative instruments, which consist of foreign currency forward contracts, including embedded derivatives, and interest rate swap contracts, are primarily determined based on the present value of future cash flows using model-derived valuations that use observable inputs such as interest rates, credit spreads and foreign currency exchange rates. We use derivative instruments principally to reduce our exposure to market risks from changes in foreign currency exchange rates and interest rates. We do not enter into or hold derivative instruments for speculative trading purposes. We transact business globally and are subject to risks associated with changing foreign currency exchange rates. We enter into foreign currency hedges such as forward and option contracts that change in value as foreign currency exchange rates change. Our most significant foreign currency exposures relate to the British pound sterling, the euro, the Canadian dollar, the Australian dollar, the Norwegian kroner and the Polish zloty. These contracts hedge forecasted foreign currency transactions in order to minimize fluctuations in our earnings and cash flows associated with changes in foreign currency exchange rates. We designate foreign currency hedges as cash flow hedges. We also are exposed to the impact of interest rate changes primarily through our borrowing activities. For fixed rate borrowings, we may use variable interest rate swaps, effectively converting fixed rate borrowings to variable rate borrowings in order to hedge changes in the fair value of the debt. These swaps are designated as fair value hedges. For variable rate borrowings, we may use fixed interest rate swaps, effectively converting variable rate borrowings to fixed rate borrowings in order to minimize the impact of interest rate changes on earnings. These swaps are designated as cash flow hedges. We also may enter into derivative instruments that are not designated as hedges and do not qualify for hedge accounting, which are intended to minimize certain economic exposures. The aggregate notional amount of our outstanding interest rate swaps was $1.3 billion at both March 31, 2024 and December 31, 2023. The aggregate notional amount of our outstanding foreign currency hedges was $6.2 billion and $6.5 billion at March 31, 2024 and December 31, 2023. The fair values of our outstanding interest rate swaps and foreign currency hedges at March 31, 2024 and December 31, 2023 were not significant. Derivative instruments did not have a material impact on net earnings and comprehensive income during the quarters ended March 31, 2024 and March 26, 2023. The impact of derivative instruments on our consolidated statements of cash flows is included in net cash provided by operating activities. Substantially all of our derivatives are designated for hedge accounting. We also make investments in early-stage companies that we believe are advancing or developing new technologies applicable to our business. Investments that have quoted market prices in active markets (Level 1) are recorded at fair value and reflected in other securities while certain investments are categorized as Level 3 when valuations using observable inputs are unavailable. See “Note 10 - Other - Investments” for more information. In addition to the financial instruments listed in the table above, we hold other financial instruments, including cash and cash equivalents, receivables, accounts payable and debt. The carrying amounts for cash and cash equivalents, receivables and accounts payable approximated their fair values. The estimated fair value of our outstanding debt was $19.9 billion and $18.5 billion at March 31, 2024 and December 31, 2023. The outstanding principal amount of debt, including short-term and long-term debt, was $20.7 billion and $18.7 billion at March 31, 2024 and December 31, 2023, excluding $1.3 billion of unamortized discounts and issuance costs at both March 31, 2024 and December 31, 2023. The estimated fair values of our outstanding debt were determined based on the present value of future cash flows using model-derived valuations that use observable inputs such as interest rates and credit spreads (Level 2).

Equity [Abstract]
STOCKHOLDERS' EQUITY	STOCKHOLDERS’ EQUITY Repurchases of Common Stock During the quarter ended March 31, 2024, we repurchased 2.3 million shares of our common stock for $1.0 billion in open market purchases. The total remaining authorization for future common stock repurchases under our share repurchase program was $9.0 billion as of March 31, 2024. As we repurchase our common shares, we reduce common stock for the $1 of par value of the shares repurchased, with the excess purchase price over par value recorded as a reduction of additional paid-in capital. If additional paid-in capital is reduced to zero, we record the remainder of the excess purchase price over par value as a reduction of retained earnings. Dividends We declared cash dividends totaling $763 million ($3.15 per share) during the quarter ended March 31, 2024. The total amount of dividends declared may differ from the total amount of dividends paid during a period due to the timing of dividend-equivalents paid on RSUs and PSUs. These dividend-equivalents are accrued during the vesting period and are paid upon the vesting of the RSUs and PSUs, which primarily occurs in the first quarter each year.

OTHER	Mar. 31, 2024
Accounting Policies [Abstract]
OTHER	OTHER Contract Estimates Significant estimates and assumptions are made in estimating contract sales, costs, and profit. We estimate profit as the difference between estimated revenues and total estimated costs to complete the contract. At the outset of a long-term contract, we identify and monitor risks to the achievement of the technical, schedule and cost aspects of the contract, as well as our ability to earn variable consideration, and assess the effects of those risks on our estimates of sales and total costs to complete the contract. The estimates consider the technical requirements (e.g., a newly-developed product versus a mature product), the schedule and associated tasks (e.g., the number and type of milestone events) and costs (e.g., material, labor, subcontractor, overhead, general and administrative and the estimated costs to fulfill our industrial cooperation agreements, sometimes referred to as offset or localization agreements, required under certain contracts with international customers). The initial profit booking rate of each contract considers risks surrounding the ability to achieve the technical requirements, schedule and costs in the initial estimated total costs to complete the contract. Profit booking rates may increase during the performance of the contract if we successfully retire risks related to technical, schedule and cost aspects of the contract, which decreases the estimated total costs to complete the contract or may increase the variable consideration we expect to receive on the contract. Conversely, our profit booking rates may decrease if the estimated total costs to complete the contract increase or our estimates of variable consideration we expect to receive decrease. All of the estimates are subject to change during the performance of the contract and may affect the profit booking rate. When estimates of total costs to be incurred on a contract exceed total estimates of the transaction price, a provision for the entire loss is determined at the contract level and is recorded in the period in which the loss is evident, which we refer to as a reach-forward loss. Comparability of our segment sales, operating profit and operating margin may be impacted favorably or unfavorably by changes in profit booking rates on our contracts. Increases in the profit booking rates, typically referred to as favorable profit booking rate adjustments, usually relate to revisions in the estimated total costs to fulfill the performance obligations that reflect improved conditions on a particular contract. Conversely, conditions on a particular contract may deteriorate, resulting in an increase in the estimated total costs to fulfill the performance obligations and a reduction in the profit booking rate and are typically referred to as unfavorable profit booking rate adjustments. Increases or decreases in profit booking rates are recognized in the current period they are determined and reflect the inception-to-date effect of such changes. Segment operating profit and margin can be impacted favorably or unfavorably by, for example, certain items listed below, which may or may not impact sales. Favorable items include the positive resolution of contractual matters, cost recoveries on severance and restructuring, insurance recoveries and gains on sales of assets. Unfavorable items include the adverse resolution of contractual matters; supply chain disruptions; restructuring charges (except for significant severance actions, which are excluded from segment operating results); reserves for disputes; certain asset impairments; and losses on sales of certain assets. Our consolidated net profit booking rate adjustments increased sales by $272 million during the quarter ended March 31, 2024 and $433 million during the quarter ended March 26, 2023. These adjustments increased segment operating profit by approximately $195 million ($154 million, or $0.64 per share, after tax) during the quarter ended March 31, 2024, and $415 million ($328 million, or $1.28 per share, after tax) during the quarter ended March 26, 2023. The impact to 2024 segment operating profit includes a reach-forward loss of $100 million recognized on a classified program at our MFC business segment described below. We have various development programs for new and upgraded products, services, and related technologies which have complex design and technical challenges. This development work is inherently uncertain and subject to significant variability in estimates of the cost and time required to complete the work by us and our suppliers. Many of these programs have cost-type contracting arrangements (e.g. cost-reimbursable or cost-plus-fee). In such cases, the associated financial risks are primarily in reduced fees, lower profit rates, or program cancellation if cost, schedule, or technical performance issues arise. However, some of our existing development programs are contracted on a fixed-price basis or include cost-type contracting for the development phase with fixed-price production options and our customers are increasingly implementing procurement policies such as these that shift risk to contractors. Competitively bid programs with fixed-price development work or fixed-price production options increase the risk of a reach-forward loss upon contract award and during the period of contract performance. Due to the complex and often experimental nature of development programs, we may experience (and have experienced in the past) technical and quality issues during the development of new products or technologies for a variety of reasons. Our development programs are ongoing, and while we believe the cost and fee estimates incorporated in the financial statements are appropriate, the technical complexity of these programs and fixed-price contract structure creates financial risk as estimated completion costs may exceed the current contract value, which could trigger earnings charges, termination provisions, or other financially significant exposures. These programs have risk for reach-forward losses if our estimated costs exceed our estimated contract revenues, and such losses could be significant to our financial results, cash flows, or financial condition. Any such losses are recorded in the period in which the loss is evident. We have experienced performance issues on a classified fixed-price incentive fee contract that involves highly complex design and systems integration at our Aeronautics business segment and have periodically recognized reach-forward losses. As of March 31, 2024, we recognized additional losses of $20 million related to technical challenges that have resulted in schedule delays and higher than anticipated costs bringing cumulative losses to approximately $290 million. We will continue to monitor the technical requirements and our performance, the remaining work and any future changes in scope or schedule, and estimated costs to complete the program and may have to record additional losses in future periods if we experience further performance issues, increases in scope, or cost growth, which could be material to our financial results. In addition, we and our industry team will continue to incur advanced procurement costs (also referred to as pre-contract costs) in order to enhance our ability to achieve the schedule and certain milestones. We will monitor the recoverability of pre-contract costs, which could be impacted by the customer’s decision regarding future phases of the program. We are responsible for a program to design, develop and construct a ground-based radar at our RMS business segment. The program previously experienced performance issues for which we have periodically recognized reach-forward losses. During the first quarter of 2024, we delivered and the customer accepted the radar, which retired the technical risk on the production scope at less than anticipated cost. As a result, we reduced the cumulative losses on the program by $20 million to approximately $260 million as of March 31, 2024 and determined that additional losses will not be incurred as the production scope of work is winding down. We have contracted with the Canadian Government for the Canadian Maritime Helicopter Program (CMHP) at our RMS business segment that provides for design, development, and production of CH-148 aircraft (the Original Equipment contract), which is a military variant of the S-92 helicopter, and for logistical support to the fleet (the In Service Support contract) over an extended time period. We are currently in discussions with the Canadian Government to potentially restructure certain contractual terms and conditions that may be beneficial to both parties. The program has experienced performance issues, including delays in the final aircraft deliveries from the original contract requirement, and the Royal Canadian Air Force’s flight hours have been significantly less than originally anticipated, which has impacted program revenues and the recovery of our costs under this program. We have incurred significant costs and recognized the related sales, of which about $970 million are currently included in contract assets on the balance sheet which could become at risk for future recovery. Such assets are recovered based on flight hours. Future sales and recovery of costs under the program are highly dependent upon achieving a certain number of flight hours, which are not entirely in our control and dependent on aircraft availability and performance, the availability of Canadian government resources, and potential restructured contract terms and conditions to better align with the current needs of the Canadian government and allow for cost recovery. As of March 31, 2024, cumulative losses remained at approximately $100 million. Future performance issues, lower than forecast flight hours, or changes in our estimates due to the outcome of any restructuring discussions may further affect our ability to recover our costs, including recovery of the contract assets recognized on the balance sheet and our assessment of the reach-forward loss, which could be material to our operating results. We also have a number of contracts with Türkish industry for the Türkish Utility Helicopter Program (TUHP), which anticipates co-production with Türkish industry for production of T70 helicopters for use in Türkiye, as well as the related provision of Türkish goods and services under buy-back or offset obligations, to include the future sales of helicopters built in Türkiye for sale globally. In 2020, the U.S. Government imposed certain sanctions on Türkish entities and persons that have affected our ability to perform under the TUHP contracts and we have provided force majeure notices under the affected contracts. As of March 31, 2024, cumulative losses related to development work for the program remained insignificant and the program remains in a contract liability position on the balance sheet. The TUHP contracts may be negotiated to be restructured or terminated, either in whole or in part and as a result, we could be at risk of recording significant reach-forward losses in future periods. Additionally, we could elect to pursue other relief or remedies, which could result in a further reduction in sales, the imposition of penalties or assessment of damages, and increased unrecoverable costs, which could be material to our financial results. Our MFC business segment was previously awarded a competitively bid classified contract, which includes a cost-reimbursable base contract for the initial phase of the program and multiple fixed price options for additional phases. The options for additional phases may be exercised over the next several years and if performed we expect they would each be at a loss. During the first quarter of 2024, we updated our assessment of the likelihood that the options may be exercised and concluded it was probable that an option would be exercised based on progress made on the program and discussions with the customer. Accordingly, in the first quarter of 2024 we recognized a reach forward loss of approximately $100 million, bringing the cumulative losses recognized on the program to approximately $150 million, including charges for precontract costs recognized in prior periods. We will continue to assess the likelihood that additional options will be exercised, utilizing factors such as our performance, future requirements of the program, discussions with the customer and suppliers, customer funding, experience with other customer programs, among other factors. We will be required to recognize additional losses for the remaining options if they become probable of being exercised. The potential total loss across the additional options is up to approximately $1.3 billion. The ultimate amount of additional loss recognized, if any, will depend on how many of the additional options are exercised or become probable of being exercised. Backlog Backlog (i.e., unfulfilled or remaining performance obligations) represents the sales we expect to recognize for our products and services for which control has not yet transferred to the customer. It is converted into sales in future periods as work is performed or deliveries are made. For our cost-reimbursable and fixed-priced-incentive contracts, the estimated consideration we expect to receive pursuant to the terms of the contract may exceed the contractual award amount. The estimated consideration is determined at the outset of the contract and is continuously reviewed throughout the contract period. In determining the estimated consideration, we consider the risks related to the technical, schedule and cost impacts to complete the contract and an estimate of any variable consideration. Periodically, we review these risks and may increase or decrease backlog accordingly. As the risks on such contracts are successfully retired, the estimated consideration from customers may be reduced, resulting in a reduction of backlog without a corresponding recognition of sales. As of March 31, 2024, our ending backlog was $159.4 billion. We expect to recognize approximately 38% of our backlog over the next 12 months and approximately 62% over the next 24 months as revenue with the remainder recognized thereafter. Income Taxes Our effective income tax rates were 15.8% and 15.3% for the quarters ended March 31, 2024 and March 26, 2023. The rates for all periods benefited from research and development tax credits, tax deductions for foreign derived intangible income, dividends paid to our defined contribution plans with an employee stock ownership plan feature and employee equity awards. Investments We make investments in companies that we believe are advancing or developing new technologies applicable to our business. These investments are primarily in early-stage companies and may be in the form of common or preferred stock, warrants, convertible debt securities, investments in funds or equity method investments. Most of these investments are in equity securities without readily determinable fair values (privately held securities), which are measured initially at cost and are then adjusted to fair value only if there is an observable price change or reduced for impairment, if applicable. The carrying amounts of the investments were $597 million and $581 million at March 31, 2024 and December 31, 2023. Due to changes in fair value and/or sales of investments, we recorded net gains of $5 million ($4 million, or $0.02 per share, after-tax) during the quarter ended March 31, 2024 and net gains of $29 million ($22 million, or $0.09 per share, after-tax) during the quarter ended March 26, 2023. These gains are reflected in the other non-operating income, net account on our consolidated statements of earnings. Debt Issuance On January 29, 2024, we issued a total of $2.0 billion of senior unsecured notes, consisting of $650 million aggregate principal amount of 4.50% Notes due 2029 (the “2029 Notes”), $600 million aggregate principal amount of 4.80% Notes due 2034 (the “2034 Notes”) and $750 million aggregate principal amount of 5.20% Notes due 2064 (the “2064 Notes” and, together with the 2029 Notes and 2034 Notes, the “Notes”). Net proceeds of $1.98 billion were received from the offering after deducting pricing discounts and debt issuance costs, which are being amortized and recorded as interest expense over the term of the Notes. We will pay interest on the Notes semi-annually in arrears on February 15 and August 15 of each year with the first payment to be made on August 15, 2024. We may, at our option, redeem the Notes of any series in whole or in part at any time and from time to time at a redemption price equal to the greater of 100% of the principal amount of the Notes to be redeemed or an applicable make-whole amount, plus accrued and unpaid interest to the date of redemption. The Notes rank equally in right of payment with all of our existing unsecured and unsubordinated indebtedness.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
EARNINGS PER COMMON SHARE	We compute basic and diluted earnings per common share by dividing net earnings by the respective weighted average number of common shares outstanding for the periods presented. Our calculation of diluted earnings per common share also includes the dilutive effects for the assumed vesting of outstanding restricted stock units (RSUs) and performance stock units (PSUs) based on the treasury stock method. There were no significant anti-dilutive equity awards during the quarters ended March 31, 2024 and March 26, 2023. Basic and diluted weighted average common shares outstanding decreased in 2024 compared to 2023 due to share repurchases.
