Accounting Policies [Abstract]
BASIS OF PRESENTATION	NOTE A: BASIS OF PRESENTATION 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 the 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 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. The accompanying Condensed Consolidated Financial Statements should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended January 2, 2026 (our “Fiscal 2025 Form 10-K”). The accompanying Condensed Consolidated Balance Sheet as of January 2, 2026 has been derived from our audited financial statements in our Fiscal 2025 Form 10-K. Our fiscal year is based on a 52- or 53-week period ending on the Friday nearest December 31. The fiscal quarters ended October 2, 2026 (“third quarter 2026”) and October 3, 2025 (“third quarter 2025”) include thirteen and fourteen weeks, respectively. The year-to-date periods ended October 2, 2026 (“year to date 2026”) and October 3, 2025 (“year to date 2025”) both include thirty-nine weeks. Segment Reorganization Effective in fiscal 2026, we streamlined our operating segments, which are also our reportable segments or business segments, from four segments to three segments, more closely aligning common capabilities and business models. We report our financial results in the following three reportable segments, consistent with the manner in which our Chief Operating Decision Maker (“CODM”) manages the business, evaluates performance, and allocates resources: Space & Mission Systems (“SMS”): Integrates satellite and payload capabilities, including missile warning and defense, with maritime, air special missions, and other global defense and civil government programs; Communications & Spectrum Dominance (“CSD”): Combines all of our capabilities in resilient communications and electronic warfare; and Missile Solutions (“MSL”): Unites propulsion, sensing, guidance, and other advanced missile and munition technologies for delivery of end-to-end missile solutions. Information on the reallocation of goodwill in connection with the segment reorganization can be found under the “Reallocation of Goodwill in Segment Reorganization” heading in Note E: Goodwill and Intangible Assets in our Form 10-Q for first quarter 2026, which information is incorporated herein by reference. The historical results, discussion and presentation of our business segments as set forth in the accompanying Condensed Consolidated Financial Statements and these Notes reflect the impact of these changes for all periods presented in order to present segment information on a comparable basis. There is no impact on our previously reported consolidated statements of operations, balance sheets, statements of cash flows or statements of equity resulting from these changes. 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 classification of certain prior year amounts has been adjusted in our Condensed Consolidated Financial Statements and these Notes to conform to current year classifications. Recently Issued Accounting Pronouncements In May 2026, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2026-02, Environmental Credits and Environmental Credit Obligations, which provides guidance on how companies should recognize, measure, and present environmental credits and environmental credit obligations in their financial statements. ASU 2026-02 is effective for annual and interim reporting periods beginning after December 15, 2027, and should be applied retrospectively. We are currently evaluating the potential impact of adopting ASU 2026-02 on our operating results, financial position and cash flows. For information on accounting pronouncements issued prior to fiscal 2026, see Note 1: Significant Accounting Policies in our Fiscal 2025 Form 10-K.
