Boeing has secured a defense contract worth up to $131 billion from the U.S. Air Force for F-15 program support, including maintenance, upgrades, retrofits, systems integration, and sustainment work. The agreement runs through August 2037 and covers F-15 aircraft used by U.S. forces as well as international partners including Japan, Israel, and Saudi Arabia.

Shares of Boeing, listed as BA, rose about 1% in premarket trading to $213.02 after the announcement.

The contract is expected to support work at Boeing’s St. Louis manufacturing facility. Boeing recently finalized a five-year labor agreement with union workers at that site in 2025, which matters because the award ties a large, long-running defense program to one of the company’s key U.S. production and support locations.

Industry analyst Rob Stallard of Vertical Research Partners said on Tuesday, “That’s a lot of F-15 support,” referring to the scope of the agreement, which includes both maintenance services and aircraft upgrade programs.

The F-15, originally developed by McDonnell Douglas in the 1970s, has undergone multiple upgrades over time. Its newest version, the F-15EX Eagle II, entered service in 2021. Boeing says the aircraft has greater weapons-carrying capacity than any other fighter jet currently deployed.

Boeing’s defense and space business has struggled in recent years. Inflation pressures hurt fixed-price contracts, contributing to a $5.4 billion operating loss in 2024 and a $128 million loss in 2025. The division had not posted an annual profit since 2021.

However, performance improved in the first half of 2026, when the defense and space segment reported a $218 million operating profit on revenue of $15.1 billion. Boeing’s total revenue for the same period was about $47 billion.

The new agreement gives the division a long-term revenue stream tied to a long-established aircraft platform, adding more visibility to a part of the business that has been under pressure even as Boeing works through broader operating and production challenges.

BA shares had fallen 3% year to date before Tuesday’s session and were down 7% over the previous 12 months. The stock had climbed above $240 in early August before easing back as crude oil prices rose from about $77 to $86 per barrel in recent weeks.

Aviation fuel costs can affect airline operating budgets and may influence aircraft purchasing decisions, which can in turn affect Boeing’s commercial business. Earlier this year, BA slipped below $190 in March before rebounding above $240 by May.

Boeing’s commercial aircraft division remains the main driver of day-to-day moves in BA stock, but the F-15 support contract stands out as one of the company’s largest defense services awards in recent years.
