[Discussion] Boeing Lands $8.58B Contract to Build Israel's F-15ia Fleet, Up to 50 Jets by 2035

[Uncrowned Guard]

Contract Award and Program Scope

A U.S. government contract notice dated December 29, 2025, confirms that Boeing has received a ceiling $8.58 billion award to support Israel’s F-15IA fighter program. The agreement covers the design, integration, testing, production, and delivery of 25 new F-15IA aircraft for the Israeli Air Force, with an option for 25 additional jets. Work will be performed primarily in St. Louis, Missouri, and is scheduled to continue through December 31, 2035. At the time of the award, $840 million in Foreign Military Sales funds were obligated.

Contract Structure and Timeline

The award is structured as a hybrid arrangement combining cost-plus-fixed-fee with firm fixed price and fixed price incentive firm target elements. It was issued as an undefinitized contract action, allowing engineering and long-lead activities to begin while final scope and pricing are completed. This structure reflects the program’s emphasis on extended integration and systems development rather than a straightforward airframe purchase. While a 2024 congressional notification suggested deliveries could begin in 2029, later reporting has cited 2031 as a planning assumption, underscoring potential shifts between notification estimates and production realities.

Relationship to Prior U.S. Notifications

The December 2025 notice builds on an August 2024 Defense Security Cooperation Agency notification to Congress that outlined a possible sale of up to 50 F-15IA multirole fighters, along with mid-life update kits for 25 existing F-15I aircraft. That package included engines, radars, mission systems, targeting and navigation pods, weapons interfaces, secure communications, and program support. Together, the disclosures frame the F-15IA effort as a multiyear modernization and expansion of Israel’s heavy fighter fleet.

Aircraft Configuration and Systems

The F-15IA represents Israel’s customized variant within Boeing’s Advanced Eagle family. Publicly disclosed elements include the AN/APG‑82(V)1 AESA radar, F110‑GE‑129 engines, Advanced Display Core Processor II, Embedded GPS/INS with M‑Code, Joint Helmet Mounted Cueing System, and secure identification and communications equipment. The inclusion of systems such as the AN/AAQ‑13 LANTIRN navigation pod supports low‑altitude, all‑weather operations, enhancing routing reliability and time‑on‑target execution in degraded conditions.

Payload, Missions, and Operational Role

Configured for heavy payload and long-range persistence, the F-15IA can carry dense air‑to‑air missile loads using LAU‑128 launchers, supported by an internal M61A cannon. Boeing has noted that the latest Eagle variants can carry up to 12 AMRAAMs in certain configurations, while retaining capacity for precision air‑to‑ground and standoff weapons. This payload margin supports defensive counter air, escort, and long‑range strike missions, emphasizing endurance, magazine depth, and sustained sortie generation.

Strategic Implications

With a potential scale of up to 50 aircraft and a program horizon extending to the mid‑2030s, the F‑15IA acquisition is positioned to influence Israel’s airpower posture well before deliveries are complete. The program formalizes a long‑term framework for heavy fighter operations centered on persistence, modernized avionics, and high‑capacity weapons employment, reinforcing Israel’s ability to sustain air operations across a range of defensive and offensive missions while deepening U.S.–Israel defense cooperation.
