St. Louis, Missouri — The U.S. Department of War has awarded Boeing an indefinite-delivery/indefinite-quantity (IDIQ) contract with a ceiling value of $131.23 billion for the F-15 Eagle Crest program. The agreement covers F-15 aircraft production, systems integration, modernization, upgrades, retrofits, sustainment and the establishment of organic depot maintenance capabilities.
The contract supports F-15 operations for the U.S. Air Force, Air National Guard and other Department of War customers. It also provides a framework for Foreign Military Sales to Japan, Israel, Saudi Arabia, South Korea, Singapore, Indonesia and Poland.
Contract Structure
The $131.23 billion figure is the maximum potential value of the IDIQ contract and does not represent an immediate payment or a single aircraft order. Individual orders can be placed as requirements arise during the contract period. At the time of award, $343,740 in fiscal 2026 research, development, test and evaluation funds was obligated.
The contract was awarded on a sole-source basis. The initial ordering period runs through August 24, 2031, with an option to extend ordering through August 24, 2036. Work is expected to continue through August 2037, with the primary work location in St. Louis, Missouri. The Air Force Life Cycle Management Center at Wright-Patterson Air Force Base, Ohio, is the contracting activity.
F-15 Production and Modernization
The framework covers capabilities associated with the F-15 Eagle Weapon System, including production of new aircraft, systems integration, modernization, upgrades, retrofits and sustainment. It also includes the establishment of organic depot maintenance capabilities for F-15 aircraft.
For the United States, the agreement provides a mechanism for additional F-15 procurement and modernization beyond the previously planned fleet of about 100 F-15EX aircraft. The F-15EX Eagle II is intended to support the replacement of aging F-15E Strike Eagles as the U.S. Air Force continues to maintain its heavy strike capability.
Foreign Military Sales
The Eagle Crest framework also supports potential Foreign Military Sales involving Japan, Israel, Saudi Arabia, South Korea, Singapore, Indonesia and Poland. Existing F-15 operators can use the framework for new aircraft or upgrades to aircraft already in service.
Boeing already has a production contract for F-15EX Eagle II aircraft for Israel and continues to market the aircraft to other potential customers, including Saudi Arabia.
Indonesia has discussed acquiring up to 36 F-15EX fighters, which have been associated with the F-15IDN designation. However, a government-to-government Letter of Offer and Acceptance has not yet been approved.
Poland has also been identified as a potential customer for 36 aircraft. Warsaw has not made an official commitment, and the U.S. State Department has not announced approval of a possible Polish request.
The Eagle Crest contract therefore establishes a long-term framework through which the United States and eligible international customers can order new F-15 aircraft, modernization packages and other F-15 support as requirements are approved.
