Boeing Secures Major Contract for F-15 Fighter Jets

The U.S. Air Force has granted Boeing an exclusive contract with a potential maximum value of $131.23 billion to produce, update, and maintain F-15 fighter aircraft for both domestic and international clients until the year 2037.

Under the designation F-15 Eagle Crest, the contract awarded on August 24 allows the Air Force to place orders incrementally over time instead of committing to a fixed number of aircraft upfront. The contract enables orders to be made up until August 24, 2031, with the possibility of extension until 2036. This comprehensive agreement encompasses new aircraft production, enhancements, refits, ongoing maintenance, and depot support all under one unified contract for the benefit of the Air Force, the Air National Guard, and international customers.

Enhanced Maintenance Capabilities and Contract Details

This contract also includes provisions for establishing organic depot-level maintenance capabilities, allowing Air Force maintenance depots to undertake extensive overhauls in-house rather than depending solely on Boeing. The work related to the contract will be carried out in St. Louis. The Air Force Life Cycle Management Center, located at Wright-Patterson Air Force Base in Ohio, is responsible for overseeing this contract.

It is important to note that the awarded amount does not necessarily mean the full $131.23 billion will be spent; this figure merely sets the upper limit of potential spending under the contract’s terms. At the time of the award, just $343,740 was obligated for research, development, testing, and evaluation purposes for the fiscal year 2026.

Unlike some previous contracts, this announcement did not include an immediate order for any aircraft. By comparison, in August 2020, when Lockheed Martin was awarded a 10-year, $62 billion contract for F-16 exports, it included an initial order of $4.94 billion for 90 jets.

International Impact and Future Plans

The contract announcement on August 24 also highlighted that the deal would support foreign military sales to several countries, including Japan, Israel, Saudi Arabia, South Korea, Singapore, Indonesia, and Poland, with the latter two countries not currently operating F-15s.

Israel, in particular, is continuing its acquisition of F-15s from the St. Louis production line. An agreement detailed in a report associated with the fiscal 2027 budget, dated December 29, 2025, discusses the purchase of 25 F-15IA jets with an option for an additional 25, totaling $8.58 billion. This purchase is said to help stabilize the supply chain and extend the active manufacturing life of the F-15EX production line.

The same report indicated an increase in the U.S. purchase of F-15EX jets to 268 from the original 98 by fiscal 2031, necessitating upgrades to the radar, mission computer, electronic warfare suite, and engines.

However, the program is expected to miss its full operational capability date of July 2027 due to a 15-week strike at Boeing’s St. Louis facility from August 4 to November 17, 2025, and challenges in meeting production recovery targets. The Air Force is considering a redefinition of what full operational capability will entail as a part of its strategy to address these delays.
