Accounting Policies [Abstract]
Equity Method Investments	Equity Method Investments We hold a 50% membership interest in United Launch Alliance (ULA), with The Boeing Company (Boeing) holding the other 50% interest. We account for this investment under the equity method, with $578 million and $551 million recorded in other noncurrent assets on our consolidated balance sheets at September 27, 2026 and December 31, 2025. During the first quarter of 2026, ULA’s Vulcan Centaur rocket experienced performance challenges that are negatively affecting ULA’s financial condition and results of operations. In the third quarter of 2026, ULA amended and restated its credit agreement, for which we agreed to guarantee certain ULA borrowings under which maximum potential future principal payments amount to $750 million. We and Boeing expect to provide additional financial support to ULA to support its liquidity or ongoing operations and could incur impairment and operating losses if the Vulcan Centaur rocket does not perform consistent with ULA’s assumptions.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In September 2025, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2025-06, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This guidance removes all references to project stages throughout FASB Accounting Standards Codification (ASC) Subtopic 350-40, Internal-Use Software and clarifies the threshold entities apply to begin capitalizing costs. Under the new standard, cost capitalization should only commence when an entity has committed to funding a software project and it is probable the project will be completed and the software will be used for its intended function. The amendments are effective for annual and interim reporting periods beginning January 1, 2028. Entities may apply the guidance using a prospective, retrospective or modified transition approach.

The ASU requires entities to disclose certain expenses, including purchases of inventory, employee compensation, depreciation, and intangible asset amortization, by caption. In addition, entities must provide a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively.
