Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE A: BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The accompanying Condensed Consolidated Financial Statements include the accounts of L3Harris Technologies, Inc. and its consolidated subsidiaries. As used in these notes to Condensed Consolidated Financial Statements (these “Notes”), the terms “L3Harris,” “Company,” “we,” “our” and “us” refer to L3Harris Technologies, Inc. and its consolidated subsidiaries. Intercompany transactions and accounts have been eliminated. The accompanying Condensed Consolidated Financial Statements have been prepared by L3Harris in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, such interim financial statements do not include all information and footnotes necessary for a complete presentation of financial condition, results of operations, cash flows and equity in conformity with GAAP for annual financial statements and are not necessarily indicative of the results that may be expected for the full fiscal year or any subsequent period. In the opinion of management, these interim financial statements reflect all adjustments (including normal recurring adjustments) considered necessary for a fair presentation of our financial condition, results of operations, cash flows and equity for the periods presented therein. The balance sheet at December 29, 2023 has been derived from our audited financial statements, but does not include all of the information and footnotes required by GAAP for annual financial statements. The accompanying Condensed Consolidated Financial Statements should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended December 29, 2023 (our “Fiscal 2023 Form 10-K”). Use of Estimates The preparation of financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in the accompanying Condensed Consolidated Financial Statements and these Notes and related disclosures. These estimates and assumptions are based on experience and other information available prior to issuance of the accompanying Condensed Consolidated Financial Statements and these Notes. Materially different results can occur as circumstances change and additional information becomes known. Reclassifications The classifications of certain prior year amounts have been adjusted in our Condensed Consolidated Financial Statements and these Notes to conform to current year classifications. Recently Issued Accounting Pronouncements Information on recently issued accounting pronouncements can be found in our Form 10-Q for the quarter ended March 29, 2024 .

Earnings Per Share [Abstract]
EARNINGS PER SHARE ("EPS")	NOTE B: EARNINGS PER SHARE (“EPS”) EPS is net income attributable to L3Harris common shareholders divided by either our weighted average number of basic or diluted shares outstanding. Potential dilutive common shares primarily consist of employee stock options and restricted and performance unit awards. The weighted-average number of common shares outstanding used to compute basic and diluted EPS were as follows: Quarter Ended Three Quarters Ended (In millions) September 27, 2024 September 29, 2023 September 27, 2024 September 29, 2023 Basic weighted-average common shares outstanding 189.6 189.3 189.7 189.6 Impact of dilutive share-based awards 0.9 0.8 1.0 1.0 Diluted weighted-average common shares outstanding 190.5 190.1 190.7 190.6 Diluted EPS excludes the antidilutive impact of 1.0 million and 2.7 million weighted-average share-based awards outstanding for the quarter and three quarters ended September 27, 2024, respectively, and 2.0 million weighted-average share-based awards outstanding for the three quarters ended September 29, 2023.

CONTRACT ASSETS AND CONTRACT LIABILITIES	Sep. 27, 2024
Revenue from Contract with Customer [Abstract]
CONTRACT ASSETS AND CONTRACT LIABILITIES	NOTE C: CONTRACT ASSETS AND CONTRACT LIABILITIES Contract assets mainly represent unbilled amounts typically resulting from revenue recognized exceeding amounts billed to customers for contracts utilizing the percentage of completion (“POC”) cost-to-cost revenue recognition method. Contract assets become receivables as we bill customers as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals, upon achievement of contractual milestones or upon deliveries and, in certain arrangements, the customer may withhold payment of a small portion of the contract price until contract completion. Contract liabilities include advance payments and billings in excess of revenue recognized, including deferred revenue associated with extended product warranties. Contract assets and liabilities are reported on a contract-by-contract basis at the end of each reporting period. Contract assets and contract liabilities are summarized below: (In millions) September 27, 2024 December 29, 2023 Contract assets $ 3,401 $ 3,196 Contract liabilities, current (1,878) (1,900) Contract liabilities, non-current (1) (93) (94) Net contract assets $ 1,430 $ 1,202 _______________ (1) The non-current portion of contract liabilities is included as a component of the “Other long-term liabilities” line item in our Condensed Consolidated Balance Sheet. There were no significant credit or impairment losses related to our contract assets during the quarter and three quarters ended September 27, 2024 or the quarter and three quarters ended September 29, 2023. Revenue recognized related to contract liabilities that were outstanding at the end of the respective prior fiscal year were $193 million and $1,241 million for the quarter and three quarters ended September 27, 2024, respectively, and $223 million and $1,121 million for the quarter and three quarters ended September 29, 2023, respectively. NOTE M: BACKLOG Backlog, which is the equivalent of our remaining performance obligations, represents the future revenue we expect to recognize as we perform on our current contracts. Backlog comprises both funded backlog (i.e., firm orders for which funding is authorized and appropriated) and unfunded backlog. Backlog excludes unexercised contract options and potential orders under ordering-type contracts, such as indefinite-delivery, indefinite-quantity contracts. At September 27, 2024, our ending backlog was $33.8 billion. We expect to recognize approximately 45% of the revenue associated with this backlog over the next twelve months and an additional 25% over the following twelve months, with the remainder to be recognized thereafter.

INCOME TAXES	NOTE F: INCOME TAXES Our effective tax rate (“ETR”) was 6.0% and 4.9% for the quarter and three quarters ended September 27, 2024, respectively, and 4.5% and 6.4% for the quarter and three quarters ended September 29, 2023, respectively. The ETR for all periods benefited from research and development (“R&D”) credits and tax deductions for foreign derived intangible income (“FDII”), with additional benefits from favorable adjustments recognized upon finalization of our 2023 tax returns in the quarter and three quarters ended September 27, 2024 and favorable resolution of specific audit uncertainties in the three quarters ended September 27, 2024 and the quarter and three quarters ended September 29, 2023. During the quarter ended September 27, 2024, we completed our 2023 Federal tax return and recorded the associated return-to-provision adjustments. On the 2023 Federal tax return, we requested an automatic tax accounting method change, pursuant to the interim guidance in Section 8 of IRS Notice 2023-63, adjusting our percentage of completion method for tax purposes to include the amortization of research and experimental expenditures, rather than the capitalized amount of such expenditures. This automatic tax accounting method change resulted in an increase to income taxes receivable and an offsetting increase in our deferred income taxes.

(collectively, the “March Issued 2024 Notes”). The March Issued 2024 Notes were used to repay Term Loan 2025, including related fees and expenses, which had an outstanding balance of $2.25 billion at December 29, 2023. Interest on the March Issued 2024 Notes is payable semi-annually in arrears on June 1 and December 1 of each year, commencing on December 1, 2024. On August 2, 2024, we closed the issuance and sale of $600 million aggregate principal amount of the 5.50% 2054 Notes and used the net proceeds to repay borrowings under our commercial paper program (“CP Program”). Interest on the 5.50% 2054 Notes is payable semi-annually in arrears on February 15 and August 15 of each year, commencing on February 15, 2025. We may, at our option, redeem the March Issued 2024 Notes and the 5.50% 2054 Notes at any time, and from time to time, in whole or in part, at the applicable redemption price, as defined in the respective notes. Both the March Issued 2024 Notes and the 5.50% 2054 Notes rank equally in right of payment with all of our existing unsecured and unsubordinated indebtedness. We incurred debt issuance costs of $20 million and $7 million for the March Issued 2024 Notes and the 5.50% 2054 Notes, respectively, which are being amortized over the life of each respective note. Such amortization is included as a component of the “Interest expense, net” line item in our Condensed Consolidated Statement of Operations. Long-Term Debt Repayments On March 14, 2024, we repaid the entire outstanding $2.25 billion drawn on Term Loan 2025, which at time of repayment had a variable interest rate of 6.7%, with proceeds from the issuance of the March Issued 2024 Notes, which bear fixed interest rates between 5.05% and 5.35%. Additionally, during the quarter ended June 28, 2024, we Credit Agreements On January 26, 2024, we established a new $1.5 billion, 364-day senior unsecured revolving credit facility (“2024 Credit Facility”) by entering into a 364-day credit agreement maturing no later than January 24, 2025 (“2024 Credit Agreement”) with a syndicate of lenders. We may extend the maturity of any loans outstanding under the 2024 Credit Agreement by one year, subject to the satisfaction of certain conditions. The 2024 Credit Agreement replaces the prior $2.4 billion 364-Day Credit Agreement (“2023 Credit Agreement”). At our election, borrowings under the 2024 Credit Agreement, which are designated in U.S. Dollars, bear interest at the sum of the term secured overnight financing rate or the Base Rate (as defined in the 2024 Credit Agreement), plus an applicable margin that varies based on the ratings of our senior unsecured long-term debt securities (“Senior Debt Ratings”). In addition to interest payable on the principal amount of indebtedness outstanding, we are required to pay a quarterly unused commitment fee that varies based on our Senior Debt Ratings. The 2024 Credit Agreement also contains representations, warranties, covenants and events of default that are substantially similar to the existing Revolving Credit Agreement, dated as of July 29, 2022 (“2022 Credit Agreement”) which established a $2.0 billion, five-year senior unsecured revolving credit facility. For a description of the 2022 Credit Agreement and related covenants, see Note 8: Debt and Credit Arrangements in our Fiscal 2023 Form 10-K. At September 27, 2024, we had no outstanding borrowings under either our 2024 Credit Agreement or our 2022 Credit Agreement, had available borrowing capacity of $2.3 billion, net of outstanding CP Program borrowings and we re in compliance wit h all covenants under both aforementioned credit agreements. See Note 8: Debt and Credit Arrangements in our Fiscal 2023 Form 10-K for additional information regarding our 2022 Credit Agreement and our 2023 Credit Agreement. Commercial Paper Program On January 26, 2024, we lowered the maximum amount available under our CP Program to $3.0 billion from $3.9 billion in accordance with the terms of the CP Program. The CP Program is supported by amounts available under the 2022 Credit Agreement and the 2024 Credit Agreement. The commercial paper notes are sold at par less a discount representing an interest factor or, if interest bearing, at par, and the maturities vary but may not exceed 397 days from the date of issue. The commercial paper notes will rank at least pari passu with all other unsecured and unsubordinated indebtedness. At September 27, 2024 and December 29, 2023, we had $1.2 billion and $1.6 billion in outstanding notes under our CP Program, respectively, which is included as a component of the “Short-term debt” line item in our Condensed Consolidated Balance Sheet. The outstanding notes under our CP Program had a weighted-average interest rate of 5.32% and 5.95% at September 27, 2024 and December 29, 2023, respectively.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	Sep. 27, 2024
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	NOTE K: FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability in the principal market (or most advantageous market, in the absence of a principal market) for the asset or liability in an orderly transaction between market participants at the measurement date. Entities are required to maximize the use of observable inputs and minimize the use of unobservable inputs in measuring fair value and to utilize a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable market data by correlation or other means. • Level 3 — Unobservable inputs that are supported by little or no market activity, are significant to the fair value of the assets or liabilities and reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability developed using the best information available in the circumstances. In certain instances, fair value is estimated using quoted market prices obtained from external pricing services. In obtaining such data from the external pricing services, we have evaluated the methodologies used to develop the estimate of fair value in order to assess whether such valuations are representative of fair value, including net asset value (“NAV”). Additionally, in certain circumstances, the NAV reported by an asset manager may be adjusted when sufficient evidence indicates NAV is not representative of fair value. The following table presents assets and liabilities measured at fair value on a recurring basis in our Condensed Consolidated Balance Sheet: September 27, 2024 December 29, 2023 (In millions) Total Level 1 Total Level 1 Assets Deferred compensation plan assets: (1) Equity and fixed income securities $ 121 $ 121 $ 106 $ 106 Investments measured at NAV: Corporate-owned life insurance 40 37 Total fair value of deferred compensation plan assets $ 161 $ 143 Liabilities Deferred compensation plan liabilities: (2) Equity securities and mutual funds $ 11 $ 11 $ 18 $ 18 Investments measured at NAV: Common/collective trusts and guaranteed investment contracts 338 274 Total fair value of deferred compensation plan liabilities $ 349 $ 292 _______________ (1) Represents diversified assets held in “rabbi trusts” primarily associated with our non-qualified deferred compensation plans, which we include in the “Other current assets” and “Other non-current assets” line items in our Condensed Consolidated Balance Sheet. (2) Primarily represents obligations to pay benefits under certain non-qualified deferred compensation plans, which we include in the “Compensation and benefits” and “Other long-term liabilities” line items in our Condensed Consolidated Balance Sheet. Under these plans, participants designate investment options (including stock and fixed-income funds), which serve as the basis for measurement of the notional value of their accounts. The following table presents the carrying amounts and estimated fair values of long-term debt that is not carried at fair value in our Condensed Consolidated Balance Sheet: September 27, 2024 December 29, 2023 (In millions) Carrying Amount Fair Value Carrying Amount Fair Value Term Loan 2025 (1) $ — $ — $ 2,250 $ 2,250 All other long-term debt, net (including current portion) (2) 11,733 11,921 9,273 9,199 Long-term debt, including the current portion of long-term debt, net $ 11,733 $ 11,921 $ 11,523 $ 11,449 _______________ (1) The carrying value of Term Loan 2025 approximates fair value due to its variable interest rate. (2) The fair value was estimated using a market approach based on quoted market prices for our debt traded in the secondary market. If measured at fair value, it would be categorized in Level 2 of the fair value hierarchy. The fair value of our short-term debt approximates the carrying value due to its short-term nature. If measured at fair value, the commercial paper would be classified as level 2 and other short-term debt would be classified as level 3 within the fair value hierarchy. See Note G: Debt and Credit Arrangements in these Notes and Note 8: Debt and Credit Arrangements in our Fiscal 2023 Form 10-K for further information regarding our long-term debt and CP Program. See Note E: Goodwill and Intangible Assets and Note O: Acquisitions and Divestitures in these Notes and Note 13: Acquisitions, Divestitures and Asset Sales in our Fiscal 2023 Form 10-K for additional information regarding fair value measurements associated with acquisitions, divestitures and goodwill.

CHANGES IN ESTIMATES

CHANGES IN ESTIMATES	9 Months Ended
CHANGES IN ESTIMATES	Sep. 27, 2024
Change in Accounting Estimate [Abstract]
CHANGES IN ESTIMATES	NOTE L: CHANGES IN ESTIMATES Many of our contracts utilize the POC cost-to-cost method of revenue recognition. A single estimated profit margin is used to recognize profit for each performance obligation over its period of performance. At the outset of each contract, we gauge its complexity and associated risks and establish an estimated total cost at completion. Due to the long-term nature of many of these contracts, developing these estimates often requires judgment. After establishing the estimated total cost at completion, we follow a standard estimate at completion (“EAC”) process in which we review the progress and performance on our ongoing contracts. As the contracts progress, we may successfully retire risks or complexities and may add additional risks, and we adjust our estimated total cost at completion. For additional discussion of our revenue recognition policies and our EAC process, see “Critical Accounting Estimates” in Part II. Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations in our Fiscal 2023 Form 10-K. Net EAC adjustments had the following impact to earnings for the periods presented: Quarter Ended Three Quarters Ended (In millions, except per share amounts) September 27, 2024 September 29, 2023 September 27, 2024 September 29, 2023 Net EAC adjustments, before income taxes $ — $ (10) $ 19 $ (97) Net EAC adjustments, net of income taxes — (8) 15 (73) Net EAC adjustments, net of income taxes, per diluted share — (0.04) 0.08 (0.38) Revenue recognized from performance obligations satisfied in prior periods was $48 million and $135 million for the quarter and three quarters ended September 27, 2024, respectively, and $28 million and $97 million for the quarter and three quarters ended September 29, 2023, respectively.

BACKLOG

BACKLOG	9 Months Ended
BACKLOG	Sep. 27, 2024
Revenue from Contract with Customer [Abstract]
BACKLOG	NOTE C: CONTRACT ASSETS AND CONTRACT LIABILITIES Contract assets mainly represent unbilled amounts typically resulting from revenue recognized exceeding amounts billed to customers for contracts utilizing the percentage of completion (“POC”) cost-to-cost revenue recognition method. Contract assets become receivables as we bill customers as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals, upon achievement of contractual milestones or upon deliveries and, in certain arrangements, the customer may withhold payment of a small portion of the contract price until contract completion. Contract liabilities include advance payments and billings in excess of revenue recognized, including deferred revenue associated with extended product warranties. Contract assets and liabilities are reported on a contract-by-contract basis at the end of each reporting period. Contract assets and contract liabilities are summarized below: (In millions) September 27, 2024 December 29, 2023 Contract assets $ 3,401 $ 3,196 Contract liabilities, current (1,878) (1,900) Contract liabilities, non-current (1) (93) (94) Net contract assets $ 1,430 $ 1,202 _______________ (1) The non-current portion of contract liabilities is included as a component of the “Other long-term liabilities” line item in our Condensed Consolidated Balance Sheet. There were no significant credit or impairment losses related to our contract assets during the quarter and three quarters ended September 27, 2024 or the quarter and three quarters ended September 29, 2023. Revenue recognized related to contract liabilities that were outstanding at the end of the respective prior fiscal year were $193 million and $1,241 million for the quarter and three quarters ended September 27, 2024, respectively, and $223 million and $1,121 million for the quarter and three quarters ended September 29, 2023, respectively. NOTE M: BACKLOG Backlog, which is the equivalent of our remaining performance obligations, represents the future revenue we expect to recognize as we perform on our current contracts. Backlog comprises both funded backlog (i.e., firm orders for which funding is authorized and appropriated) and unfunded backlog. Backlog excludes unexercised contract options and potential orders under ordering-type contracts, such as indefinite-delivery, indefinite-quantity contracts. At September 27, 2024, our ending backlog was $33.8 billion. We expect to recognize approximately 45% of the revenue associated with this backlog over the next twelve months and an additional 25% over the following twelve months, with the remainder to be recognized thereafter.

Restructuring and Related Activities [Abstract]
RESTRUCTURING AND OTHER EXIT COSTS	NOTE N: RESTRUCTURING AND OTHER EXIT COSTS From time to time, we record charges for restructuring and other exit activities related to changes in management structure and fundamental reorganizations that affect the nature and focus of operations, such as our LHX NeXt initiative described below. Such charges may include severance benefits and costs to consolidate facilities or relocate employees. We record these charges at their fair value when incurred. In cases where employees are required to render service until they are terminated in order to receive the termination benefits and will be retained beyond the minimum retention period, we record the expense ratably over the future service period. LHX NeXt Initiative. LHX NeXt is our initiative to reduce cost and transform our systems and processes to increase agility and competitiveness, as discussed in more detail under the “Operating Environment, Strategic Priorities and Key Performance Measures” section in Part II. Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations in our Fiscal 2023 Form 10-K. Changes to our liabilities for restructuring and other exit costs during the three quarters ended September 27, 2024 were as follows: (In millions) Employee Severance Related Costs Balance at December 29, 2023 (1) $ 4 Additional provisions (2) 69 Payments (64) Total changes 5 Balance at September 27, 2024 (1) $ 9 _______________ (1) Our liabilities, which we expect will be paid in the next twelve months, are included in the “Compensation and benefits” line item in our Condensed Consolidated Balance Sheet.

ACQUISITIONS AND DIVESTITURES	Sep. 27, 2024
Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
ACQUISITIONS AND DIVESTITURES	NOTE O: ACQUISITIONS AND DIVESTITURES Acquisition of AJRD On July 28, 2023, we acquired AJRD, a technology-based engineering and manufacturing company that develops and produces missile solutions and technologies for strategic defense, missile defense, and hypersonic and tactical systems, as well as space propulsion and power systems for national security space and exploration missions. The acquisition provides us access to a new market. We acquired 100% of AJRD for a total net purchase price of $4,715 million. The acquisition was financed through the issuance and sale of the AJRD Notes and a draw down under the 2023 Credit Agreement. See Note 8: Debt and Credit Arrangements in our Fiscal 2023 Form 10-K for further information regarding the financing of the AJRD acquisition. Net assets and results of operations of AJRD are reflected in our financial results commencing on July 28, 2023, the acquisition date, and are reported in our AR segment, which is also the AR reporting unit, except for certain assets and liabilities recorded at corporate headquarters. We accounted for the acquisition of AJRD using the acquisition method of accounting, which required us to measure identifiable assets acquired and liabilities assumed in the acquiree at their fair values as of the acquisition date, with the excess of the consideration transferred over those fair values recorded as goodwill. As of the acquisition date, the fair value of consideration transferred consisted of the following: (In millions) July 28, 2023 Cash consideration paid for AJRD outstanding common stock & equity awards $ 4,748 AJRD debt settled by L3Harris 257 Cash consideration paid 5,005 Less cash acquired (290) Fair value of consideration transferred $ 4,715 We determined the fair value of assets acquired and liabilities assumed by using available market information and various valuation methods that require judgement related to estimates. Our preliminary fair value estimates and assumptions to measure the assets acquired and liabilities assumed were subject to change as we obtained additional information during the measurement period. We completed our accounting for the acquisition during the quarter ended September 27, 2024. (In millions) Preliminary as of July 28, 2023 Measurement Period Adjustments, Net (1) Final as of September 27, 2024 Receivables $ 156 $ — $ 156 Contract assets 338 (137) 201 Inventories, net 14 — 14 Income taxes receivable 3 2 5 Other current assets 114 19 133 Property, plant and equipment 574 10 584 Goodwill 2,348 554 2,902 Intangible assets 2,860 — 2,860 Other non-current assets 609 66 675 Total assets acquired $ 7,016 $ 514 $ 7,530 Current portion of long-term debt, net $ 1 $ — $ 1 Accounts payable 145 — 145 Contract liabilities 310 152 462 Compensation and benefits 116 1 117 Income taxes payable 6 (3) 3 Other current liabilities 278 390 668 Long-term debt, net 41 — 41 Deferred income taxes 398 (52) 346 Other long-term liabilities 1,006 26 1,032 Total liabilities assumed $ 2,301 $ 514 $ 2,815 Fair value of consideration transferred $ 4,715 $ — $ 4,715 _______________ (1) Fair value adjustments during the measurement period primarily related to EAC updates for circumstances existing at the acquisition date, including updates to the forward loss provision and off-market customer contract reserve described below, refinements to the fair value of fixed assets, as well as corresponding adjustments to the deferred tax liability account which was partially offset by the release of a portion of the uncertain tax position previously recorded by AJRD. Intangible Assets. All finite-lived intangible assets identified in the AJRD acquisition are subject to amortization. The fair value and weighted-average amortization period of identifiable intangible assets acquired as of the acquisition date are as follows: Total Useful Lives (In millions) (In Years) Customer relationships: Backlog $ 355 3 Government programs 2,385 15 - 20 Total customer relationships 2,740 Trade names 120 15 Total identifiable intangible assets acquired $ 2,860 The fair value of intangible assets is estimated using the relief from royalty method for the acquired trade names and the multi-period excess earnings method for the acquired customer relationships. Both of these level 3 fair value methods are income-based valuation approaches, which require judgment to estimate appropriate discount rates, royalty rates related to the trade names intangible assets, revenue growth attributable to the intangible assets and remaining useful lives. Forward Loss Provision. We have recorded a forward loss provision of $363 million which was included in the “Other current liabilities” line item in our Condensed Consolidated Balance Sheet. Since the completion of the acquisition of AJRD, we have undertaken significant operational efforts to further understand the root cause of identified preexisting manufacturing and supply chain challenges resulting in delivery delays, primarily related to certain Missile Solutions programs. We have identified operational activities necessary to remedy these challenges and inefficiencies and the incremental costs required as compared to its initial estimates and actual costs incurred. The incremental forward loss provisions relate to the increased cost estimates of labor and material to remedy the underlying preexisting technical and supply chain challenges. These cost increases impacted both cost-plus and fixed-price contracts in proportions that are consistent with the ratio of the overall AJRD revenue by contract type. The forward loss provisions will be recognized as a reduction to cost of sales as we incur actual costs associated with these estimates in satisfying the associated performance obligations. There will be no net impact on our Condensed Consolidated Statement of Operations. We recognized $46 million and $107 million of amortization related to the forward loss provision in the quarter and three quarters ended September 27, 2024, respectively. Off-market Customer Contracts. We have identified certain customer contractual obligations as of the acquisition date with economic returns that are higher or lower than could be realized in market transactions and have recorded assets or liabilities for the acquisition date fair value of the off-market components. The acquisition date fair value of the off-market components is a net liability of $183 million, consisting of $48 million and $135 million included in the “Other current liabilities” and “Other long-term liabilities” line items in our Condensed Consolidated Balance Sheet, respectively, and excludes any amounts already recognized in forward loss provisions (see discussion in the preceding paragraph). Additional provisions to off-market customer contracts relate to labor and material cost increases primarily associated with supply chain and manufacturing challenges and inefficiencies. These cost increases impacted both cost-plus and fixed-price contracts in proportions that are consistent with the ratio of the overall AJRD revenue by contract type. We measured the fair value of these components as the amount by which the terms of the contract with the customer deviates from the terms that a market participant could have achieved at the acquisition date. The off-market components of these contracts will be recognized as an increase to revenue as we incur costs to satisfy the associated performance obligations. We recognized $12 million and $42 million of amortization related to off-market contract liabilities in the quarter and three quarters ended September 27, 2024, respectively. Goodwill. The $2,902 million of goodwill recognized is attributable to AJRD’s market presence as one of the two primary providers of advanced propulsion and power systems for nearly every major U.S. government space and missile program, the assembled workforce and established operating infrastructure. The acquired goodwill is not tax deductible. See Note E: Goodwill and Intangible Assets in these Notes for further information. Financial Results. See Note P: Business Segment Information in these Notes for the AR segment financial results for the quarter and three quarters ended September 27, 2024. Acquisition-Related Costs. Pending Divestiture of Commercial Aviation Solutions (“CAS Disposal Group”) During the quarter ended December 29, 2023, we entered into a definitive agreement to sell our CAS Disposal Group for a cash purchase price of $700 million, with additional contingent consideration of up to $100 million, subject to customary purchase price adjustments and closing conditions as set forth in the agreement. As of September 27, 2024, the fair value less remaining estimated costs to sell of the CAS Disposal Group was $887 million, inclusive of consideration related to noncontrolling interest and accumulated other comprehensive income. Income before income taxes attributable to L3Harris Technologies, Inc. for the quarter and three quarters ended September 27, 2024 was $31 million and $87 million, respectively, and for the quarter and three quarters ended September 29, 2023 was $6 million and $43 million, respectively. The CAS Disposal Group, which is part of our IMS segment, provides integrated aircraft avionics, pilot training and data analytics services for the commercial aviation industry. The transaction is expected to close in fiscal 2024. In connection with the preparation of our financial statements for fiscal 2023, we concluded that goodwill related to the CAS Disposal Group was impaired and we recorded a non-cash impairment charge of $296 million, which is included in the “Impairment of goodwill and other assets” line item in our Consolidated Statement of Operations in our Fiscal 2023 Form 10-K. See Note 6: Goodwill and Intangible Assets in our Fiscal 2023 Form 10-K. Additionally, we recognized a pre-tax loss of $77 million included in the “Asset group and business divestiture-related (losses) gains, net” line item in our Consolidated Statement of Operations in our Fiscal 2023 Form 10-K. D The carrying amounts of assets and liabilities of the CAS Disposal Group classified as held for sale in our Condensed Consolidated Balance Sheet were as follows: (In millions) September 27, 2024 December 29, 2023 Receivables, net $ 96 $ 80 Contract assets 60 43 Inventories, net 158 145 Other current assets 22 33 Property, plant and equipment, net 48 41 Goodwill 536 534 Intangible assets, net 264 263 Other non-current assets 49 40 Valuation allowance (103) (73) Total assets held for sale $ 1,130 $ 1,106 Current portion of long-term debt $ 1 $ — Accounts payable 88 111 Contract liabilities 43 48 Compensation and benefits 7 11 Other current liabilities 38 38 Long-term debt, net 3 — Other long-term liabilities 63 64 Total liabilities held for sale $ 243 $ 272 Divestiture of Antenna Disposal Group On May 31, 2024, we completed the divestiture of our Antenna Disposal Group, which provides a variety of airborne and ground-based antennas and test equipment, to Kanders & Company, Inc. for net cash proceeds of $166 million (after selling costs and purchase price adjustments) and a $25 million note receivable, included in the Other non-current assets line item in our Condensed Consolidated Balance Sheet at September 27, 2024. The carrying amounts of assets and liabilities included in the Antenna Disposal Group sale on May 31, 2024 were $265 million and $65 million, respectively. During the quarter ended June 28, 2024, $93 million of goodwill was assigned to the Antenna Disposal Group on a relative fair value basis. In connection with the preparation of our financial statements for the quarter ended June 28, 2024, we tested goodwill assigned to the Antenna Disposal Group and goodwill assigned to the retained businesses of the SAS reporting unit for impairment and concluded that goodwill related to the Antenna Disposal Group was impaired. As a result, we recorded a non-cash charge for impairment of $14 million included in the “General and administrative expenses” line item in our Condensed Consolidated Statement of Operations for the three quarters ended September 27, 2024. In connection with the sale, we recognized a pre-tax loss of $9 million included in the “General and administrative expenses” line item in our Condensed Consolidated Statement of Operations for the three quarters ended September 27, 2024. The operating results of the Antenna Disposal Group were reported in our SAS segment through the date of divestiture. Divestiture of Visual Information Solutions (“VIS”) On April 6, 2023, we completed the sale of VIS for a sale price of $70 million and recognized a pre-tax gain of $26 million included in the “General and administrative expenses” line item in our Consolidated Statement of Operations for the fiscal year ended December 29, 2023 in our Fiscal 2023 Form 10-K. After selling costs and purchase price adjustments, the net cash proceeds for the sale of VIS were $71 million. The operating results of VIS were reported in the SAS segment through the date of divestiture. Fair Value of Businesses For purposes of allocating goodwill to the disposal groups that represent a portion of a reporting unit, we determine the fair value of each disposal group based on the respective negotiated selling price, and the fair value of the retained businesses of the respective reporting unit based on a combination of market-based and income-based valuation techniques, utilizing quoted market prices, comparable publicly reported transactions and projected discounted cash flows. These fair value determinations are categorized as level 3 in the fair value hierarchy due to their use of internal projections and unobservable measurement inputs. See Note K: Fair Value Measurements in these Notes for additional information.

Total unallocated corporate expenses include corporate items such as a portion of management and administration, legal, environmental, compensation, retiree benefits, other corporate expenses and eliminations and the FAS/Cost Accounting Standards (“CAS”) operating adjustment. Total unallocated corporate expenses also include the portion of corporate costs not included in management’s evaluation of segment operating performance, such as amortization of acquisition-related intangibles; additional cost of revenue related to the fair value step-up in inventory sold; merger, acquisition, and divestiture-related expenses; asset group and business divestiture-related (losses) gains, net and any related impairment of goodwill; impairment of other assets; LHX NeXt implementation costs; and other items. FAS/CAS Operating Adjustment. In accordance with CAS, we allocate a portion of pension and OPEB plan costs to our U.S. Government contracts. However, our Condensed Consolidated Financial Statements require pension and OPEB plan income or expense to be calculated in accordance with FAS requirements under GAAP. The “FAS/CAS operating adjustment” line item in the table below represents the difference between the service cost component of net periodic benefit income under our pension and OPEB plans and total CAS pension and OPEB cost.

Legal Proceedings And Contingencies [Abstract]
LEGAL PROCEEDINGS AND CONTINGENCIES	NOTE Q: LEGAL PROCEEDINGS AND CONTINGENCIES In the ordinary course of business, we are routinely defendants in, parties to or otherwise subject to many pending and threatened legal actions, claims, disputes, arbitration and other legal proceedings incident to our business, arising from or related to matters, including but not limited to: product liability; personal injury; patents, trademarks, trade secrets or other intellectual property; labor and employment disputes; commercial or contractual disputes; strategic acquisitions or divestitures; the prior sale or use of former products allegedly containing asbestos or other restricted materials; breach of warranty; or environmental matters. Claimed amounts against us may be substantial, but may not bear any reasonable relationship to the merits of the claim or the extent of any real risk of court or arbitration awards. We record accruals for losses related to those matters against us that we consider to be probable and that can be reasonably estimated. Gain contingencies, if any, are recognized when they are realized and legal costs generally are expensed when incurred. At September 27, 2024, our accrual for the potential resolution of lawsuits, claims or proceedings that we consider probable of being decided unfavorably to us was not material. We cannot at this time estimate the reasonably possible loss or range of loss in excess of our accrual due to the inherent uncertainties and speculative nature of contested proceedings. Although it is not feasible to predict the outcome of these matters with certainty, based on available information, in the opinion of management, settlements, arbitration awards and final judgments, if any, that are considered probable of being rendered against us in litigation or arbitration in existence at September 27, 2024 are reserved against or would not have a material adverse effect on our financial condition, results of operations, cash flows or equity. Environmental Matters We are subject to numerous U.S. Federal, state, local and international environmental laws and regulatory requirements and are involved from time to time in investigations or litigation of various potential environmental issues. We or companies we have acquired, including AJRD, are responsible, or alleged to be responsible, for environmental investigation and/or remediation of multiple sites, including sites owned by us and third-party sites. These sites are in various stages of investigation and/or remediation, and in some cases our liability is considered de minimis. Notices from the U.S. Environmental Protection Agency (“EPA”) or equivalent state or international environmental agencies allege that several sites formerly or currently owned and/or operated by us or companies we have acquired, and other properties or water supplies that may be or have been impacted from those operations, contain disposed or recycled materials or wastes and require environmental investigation and/or remediation. These sites include instances of us or companies we acquired being identified as a potentially responsible party (“PRP”) under the Comprehensive Environmental Response, Compensation and Liability Act (commonly known as the “Superfund Act”), the Resource Conservation Recovery Act and/or equivalent state and international laws, and in some instances, our liability and proportionate share of costs that may be shared among other PRPs have not been determined largely due to uncertainties as to the nature and extent of site conditions and our involvement. Based on an assessment of relevant factors, we estimated that our liability under applicable environmental statutes and regulations for identified sites was $654 million as of September 27, 2024. The current portion of our estimated environmental liability is included in the “Other current liabilities” line item and the non-current portion is included in the “Other long-term liabilities” line item in our Condensed Consolidated Balance Sheet. Some of these environmental costs are eligible for future recovery in the pricing of our products and services to the U.S. government and under existing third party agreements. We consider the recovery probable based on U.S. government contracting regulations and existing third-party agreements. As of September 27, 2024, we had an asset for the recoverable portion of these reserves of $468 million. The current and non-current portion of the recoverable costs are included as a component of the “Other current assets” and “Other non-current assets” line items, respectively, in our Condensed Consolidated Balance Sheet.

	Sep. 27, 2024
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying Condensed Consolidated Financial Statements include the accounts of L3Harris Technologies, Inc. and its consolidated subsidiaries. As used in these notes to Condensed Consolidated Financial Statements (these “Notes”), the terms “L3Harris,” “Company,” “we,” “our” and “us” refer to L3Harris Technologies, Inc. and its consolidated subsidiaries. Intercompany transactions and accounts have been eliminated. The accompanying Condensed Consolidated Financial Statements have been prepared by L3Harris in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, such interim financial statements do not include all information and footnotes necessary for a complete presentation of financial condition, results of operations, cash flows and equity in conformity with GAAP for annual financial statements and are not necessarily indicative of the results that may be expected for the full fiscal year or any subsequent period.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in the accompanying Condensed Consolidated Financial Statements and these Notes and related disclosures. These estimates and assumptions are based on experience and other information available prior to issuance of the accompanying Condensed Consolidated Financial Statements and these Notes. Materially different results can occur as circumstances change and additional information becomes known.
Reclassifications	Reclassifications The classifications of certain prior year amounts have been adjusted in our Condensed Consolidated Financial Statements and these Notes to conform to current year classifications.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Information on recently issued accounting pronouncements can be found in our Form 10-Q for the quarter ended March 29, 2024 .
Earnings Per Share	EPS is net income attributable to L3Harris common shareholders divided by either our weighted average number of basic or diluted shares outstanding. Potential dilutive common shares primarily consist of employee stock options and restricted and performance unit awards.
Fair Value Measurements	Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability in the principal market (or most advantageous market, in the absence of a principal market) for the asset or liability in an orderly transaction between market participants at the measurement date. Entities are required to maximize the use of observable inputs and minimize the use of unobservable inputs in measuring fair value and to utilize a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable market data by correlation or other means. • Level 3 — Unobservable inputs that are supported by little or no market activity, are significant to the fair value of the assets or liabilities and reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability developed using the best information available in the circumstances. In certain instances, fair value is estimated using quoted market prices obtained from external pricing services. In obtaining such data from the external pricing services, we have evaluated the methodologies used to develop the estimate of fair value in order to assess whether such valuations are representative of fair value, including net asset value (“NAV”). Additionally, in certain circumstances, the NAV reported by an asset manager may be adjusted when sufficient evidence indicates NAV is not representative of fair value.
