U.S. Air Force Expands Role of Boeing's F-15EX Eagle II Fighter | AIN
Multirole strike fighter could take on more complex missions than initially planned
www.ainonline.comHere’s the latest on Boeing F-15EX Eagle II based on recent public reporting up to 2026.
-
Production and deliveries: The U.S. Air Force has continued moving the F-15EX program forward, with renewed emphasis on expanding the fleet and sustaining deliveries after earlier production challenges. This includes budgeted procurement plans and ongoing integration work to increase the number of aircraft in service.[1][3][4]
-
Capabilities and upgrades: The F-15EX Eagle II remains the USAF’s most capable 4.5-generation fighter in open-circuit terms, featuring a modern AESA radar, advanced self-protection systems, and open mission system software to enable rapid upgrades. It is optimized for high payloads, long range, and multi-role operations, including potential future roles in sensing, C2, and teaming with unmanned systems.[6][9][1]
-
Fleet and roles: The Air Force has signaled interest in a larger fleet (original goals around multiple dozen to over a hundred aircraft), driven by the need to replace aging F-15C/Ds and to bridge toward next-gen concepts like joint all-domain operations. Budget documents in 2025–2026 referenced potential additional aircraft and a continued push to expand the program.[4][9]
-
Notable milestones: First flight and test milestones for Lot 2 and subsequent lots have occurred, with ongoing testing and evaluation to validate upgrades and integration with new sensors, weapons, and software. Deliveries resumed after earlier interruptions in the program, underscoring a continued focus on fielding and modernization.[3][9][6]
-
Public context and reception: Defence and aviation outlets have widely described the F-15EX as a cost-effective “bridge” platform that complements fifth-generation assets, emphasizing its payload, range, upgradeability, and rapid upgrade path via OMS software. This framing appears consistently across aerospace analysis articles and industry reports.[8][9][6]
Illustration: A high-level view of the F-15EX’s strengths includes its large payload capacity, advanced radar and sensors, and flexible open architecture that supports future upgrades and potential manned-unmanned teaming.[1][6]
If you’d like, I can pull specific figures (aircraft quantities, unit costs, and planned procurement by year) from the latest budget documents and produce a concise chart. I can also summarize primary sources in a quick side-by-side comparison with predecessors like the F-15C/D and F-35 for context.[9][4]
