Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Condensed Consolidated Financial Statements (Unaudited) include the accounts of L3Harris Technologies, Inc. and its consolidated subsidiaries. As used in these Notes to Condensed Consolidated Financial Statements (Unaudited) (these “Notes”), the terms “L3Harris,” “Company,” “we,” “our” and “us” refer to L3Harris Technologies, Inc. and its consolidated subsidiaries. Intracompany transactions and accounts have been eliminated in consolidation. The accompanying Condensed Consolidated Financial Statements (Unaudited) have been prepared by L3Harris, without an audit, in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the rules and regulations of the 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. In the opinion of management, such interim financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of our financial condition, results of operations and cash flows for the periods presented therein. The results for the quarter and two quarters ended July 3, 2020 are not necessarily indicative of the results that may be expected for the full fiscal year or any subsequent period. The balance sheet at January 3, 2020 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. We provide complete, audited financial statements in our Transition Report on Form 10-KT for the fiscal transition period from June 29, 2019 to January 3, 2020 (our “Fiscal Transition Period Form 10-KT”), which includes information and footnotes required by the rules and regulations of the SEC. The information included in this Quarterly Report on Form 10-Q (this “Report”) should be read in conjunction with the Management’s Discussion and Analysis of Financial Condition and Results of Operations and the Consolidated Financial Statements and accompanying Notes to Consolidated Financial Statements included in our Fiscal Transition Period Form 10-KT. On October 12, 2018, Harris Corporation, a Delaware corporation (“Harris”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with L3 Technologies, Inc., a Delaware corporation (“L3”), and Leopard Merger Sub Inc., a Delaware corporation and a newly formed, direct wholly owned subsidiary of Harris (“Merger Sub”), pursuant to which Harris and L3 agreed to combine their respective businesses in an all-stock merger, at the closing of which Merger Sub would merge with and into L3, with L3 continuing as the surviving corporation and a direct wholly owned subsidiary of Harris (the “L3Harris Merger”). The closing of the L3Harris Merger occurred on June 29, 2019 (the “Closing Date”), the day after Harris’ fiscal 2019 ended and the first day of the fiscal transition period ended January 3, 2020 (the “Fiscal Transition Period”). Upon completion of the L3Harris Merger, Harris was renamed “L3Harris Technologies, Inc.” (“L3Harris”), and each share of L3 common stock converted into the right to receive 1.30 shares (“Exchange Ratio”) of L3Harris common stock. Shares of L3Harris common stock, which previously traded under ticker symbol “HRS” on the New York Stock Exchange prior to completion of the L3Harris Merger, are traded under ticker symbol “LHX” following completion of the L3Harris Merger. L3Harris was owned on a fully diluted basis approximately 54 percent by Harris shareholders and 46 percent by L3 shareholders immediately following the completion of the L3Harris Merger. Because of the L3Harris Merger, the quarter and two quarters ended July 3, 2020 reflect the results of the combined company, while the quarter and two quarters ended June 28, 2019 reflect the results of only Harris operating businesses. We accounted for the L3Harris Merger under the acquisition method of accounting. Under the acquisition method of accounting, we were required to measure identifiable assets acquired, liabilities assumed and any noncontrolling interests in the acquiree at their fair values as of the Closing Date. The excess of the consideration transferred over those fair values was recorded as goodwill. See Note B — Business Combination in these Notes for additional information related to the L3Harris Merger. We implemented a new organizational structure effective on June 29, 2019, which resulted in changes to our operating segments, which are also reportable segments and referred to as our business segments. The historical results, discussion and presentation of our business segments as set forth in the accompanying Condensed Consolidated Financial Statements (Unaudited) 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 income, balance sheets, statements of cash flows or statements of equity resulting from these changes.
Use of Estimates	Use of EstimatesThe 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 (Unaudited) 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 (Unaudited) and these Notes. Materially different results can occur as circumstances change and additional information becomes known.
Adoption of New Accounting Standards	Adoption of New Accounting Standards Effective January 3, 2020, we adopted Accounting Standards Update 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments on a modified retrospective basis. The new standard replaces the existing impairment model, under which impairment of receivables is recognized when it becomes probable a loss has been incurred, with a model that requires recognition of expected credit losses over the estimated life of an asset at inception and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Adopting this standard did not have a material impact on our financial condition, results of operations or cash flows.
Restructuring and Other Exit Costs	We record charges for restructuring and other exit activities related to sales or terminations of product lines, closures or relocations of business activities, changes in management structure and fundamental reorganizations that affect the nature and focus of operations. Such charges include termination benefits, contract termination costs 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. These charges are included as a component of the “Engineering, selling and administrative expenses” line item in our Condensed Consolidated Statement of Income (Unaudited).
Fair Value Measurements	Fair value is defined as the price that would be received for an asset or the price that would be paid to transfer a liability in the principal market or most advantageous market 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.
Business Segment Information	We adjusted our segment reporting due to the L3Harris Merger to reflect our new organizational structure that was effective June 29, 2019 and announced July 1, 2019. We structure our operations primarily around the products and services we sell and the markets we serve, and we report the financial results of our operations in the following four operating segments, which are also our reportable segments and are referred to as our business segments: •Integrated Mission Systems, including multi-mission ISR and communication systems; integrated electrical and electronic systems for maritime platforms; and advanced electro-optical and infrared solutions; •Space and Airborne Systems, including space payloads, sensors and full-mission solutions; classified intelligence and cyber defense; avionics; and electronic warfare; •Communication Systems, including tactical communications; broadband communications; integrated vision solutions; and public safety; and •Aviation Systems, including defense aviation products; commercial aviation products; commercial and military pilot training; and mission networks for air traffic management. The historical results, discussion and presentation of our business segments as set forth in this Report reflect the impact of these adjustments for all periods presented. There is no impact on our previously reported consolidated statements of income, balance sheets, statements of cash flows or statements of equity resulting from these adjustments. As noted in Note C — Business Divestitures and Assets Sales and elsewhere in these Notes, during the quarter ended July 3, 2020, we completed the divestiture of our airport security and automation business, the operating results of which through the date of divestiture are reported as part of our Aviation Systems segment, and the divestiture of our Applied Kilovolts and Analytical Instrumentation business, the operating results of which through the date of divestiture are reported as part of our Space and Airborne Systems segment. The accounting policies of our business segments are the same as those described in Note 1: “Significant Accounting Policies” in the Notes to Consolidated Financial Statements in our Fiscal Transition Period Form 10-KT. We evaluate each segment’s performance based on its operating income or loss, which we define as profit or loss from operations before income taxes, including pension income and excluding interest income and expense, royalties and related intellectual property expenses, equity method investment income or loss and gains or losses from securities and other investments. Intersegment sales are generally transferred at cost to the buying segment, and the sourcing segment may recognize a profit that is eliminated. The “Corporate eliminations” line item in the table below represents the elimination of intersegment sales. Corporate expenses are allocated to our operating segments using an allocation methodology prescribed by U.S. Government regulations for government contractors. The “Pension adjustment” line item in the table below represents the reconciliation of the non-service components of net periodic pension and postretirement benefit costs, which are a component of segment operating income but are included in the “Non-operating income” line item in our Condensed Consolidated Statement of Income (Unaudited). The non-service components of net periodic pension and postretirement benefit costs include interest cost, expected return on plan assets and amortization of net actuarial gain or loss.
Disaggregation of Revenue	Disaggregation of Revenue All four segments disaggregate revenue by customer relationship, contract type and geographical region. We believe these categories best depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Integrated Mission Systems: Integrated Mission Systems revenue is primarily derived from U.S. Government development and production contracts and is generally recognized over time using the POC cost-to-cost revenue recognition method. Space and Airborne Systems: Space and Airborne Systems revenue is primarily derived from U.S. Government development and production contracts and is generally recognized over time using the POC cost-to-cost revenue recognition method.Communication Systems: Communication Systems revenue is primarily derived from fixed-price contracts and is generally recognized at the point in time when products are received and accepted by the customer for standard products offered to multiple customers and over time for customer-specific products, systems, and services.Aviation Systems: Aviation Systems revenue is primarily derived from fixed-price contracts and is generally recognized at the point in time when products are received and accepted by the customer for standard products offered to multiple customers and over time for customer-specific products, systems, and services.
