Briefing

What Hype is tracking

  • The first F-15EX deployment to Japan signals a growing role for the platform in U.S. force posture in the Pacific, alongside bomber-force demonstrations in Australia.
  • The planned increase from 129 to 267 aircraft makes F-15EX a major recapitalization program for the older F-15E fleet, but introduces management and sustainment risks.
  • The Air Force’s basing plan places F-15EXs at Seymour Johnson while shifting Strike Eagles to a former B-2 base, reshaping how the service allocates its fighter force.
