Here’s the latest I can share based on recent public reporting up to 2025–2026.
- Key milestone: Boeing’s F-15EX Eagle II has progressed through multiple Lot 2 tests and deliveries, with EX-09 representing the first Lot 2 airframe moving toward flight testing and potential further fielding in the U.S. Air Force portfolio. The program continues to expand its operational testing and integration under Air Force supervision.[1][2]
- Capabilities: The Eagle II family adds open mission systems architecture, more capable radar and electronic warfare suites, a larger payload capacity, and fly-by-wire controls aimed at improving pilot workload and survivability in modern mission sets. These features are intended to keep the platform relevant alongside stealth-enabled systems, though the F-15EX itself remains non-stealthy and relies on mission versatility and payload for its edge.[2][7]
- Production and deliveries: After initial Lot 1 deliveries, the program has aimed to steady production with Lot 2, including first flights and testing milestones that signal broader deployment within the Air Force and National Guard units. Boeing communications and defense press materials highlight ongoing development, testing at facilities like Eglin and deployment to units such as the Oregon Air National Guard’s 142 Wing for operational testing and routine readiness.[3][5][2]
If you’d like, I can pull bill-of-materials style summaries, unit deployment status, or a concise timeline of notable milestones for the F-15EX Eagle II based on public sources, and I can format a brief visual timeline as well. I can also look up the very latest official Air Force or Boeing statements if you want the freshest official wording.
