Report to Congress on U.S. Air Force Fighter Force Structure

USNI News

The United States Air Force is modernising its fighter force structure by balancing the procurement of F-35A Lightning II and F-15EX Eagle II aircraft against the development of the Next Generation Air Dominance platform. This strategic transition requires divesting legacy platforms, including F-15C/D and A-10 Thunderbolt II aircraft, to fund advanced research.

Congressional overseers face critical decisions regarding annual procurement rates, statutory inventory minimums, and the rapid integration of uncrewed Collaborative Combat Aircraft. Pilot shortages compound these capacity risks. The service's 'divest-to-invest' strategy aims to field a highly networked family of systems capable of countering near-peer adversaries in highly contested environments like the Indo-Pacific. However, retiring older airframes before fifth-generation platforms reach full-rate production creates near-term capacity gaps that worry lawmakers. Ultimately, the legislative decisions on these procurement profiles will define the global reach and deterrence posture of American airpower.

Comment

Production bottlenecks on the F-35A Lightning II assembly lines at Fort Worth expose deep vulnerabilities in Western aerospace manufacturing. Relying on single-source components like the Pratt & Whitney F135 engine limits how quickly these airframes can replace retiring F-15C fleets. This friction directly constrains fifth-generation fighter availability at critical Pacific bases like Kadena.

These manufacturing delays force the prolonged operational life of structurally fatigued F-16 Fighting Falcons. This legacy sustainment consumes research capital, slowing the Collaborative Combat Aircraft programme. Ultimately, production limits at Lockheed Martin force a reliance on older platforms vulnerable to modern air defence networks like the S-400.

Strategic Question for Discussion
If production bottlenecks for the Pratt & Whitney F135 engine persist, how will the resulting delay in F-35A deliveries alter the operational viability of the Collaborative Combat Aircraft programme?
The available evidence suggests that F-35A delivery delays would force the Air Force to decouple early Collaborative Combat Aircraft testing from fifth-generation manned platforms. My assessment is that this friction would compel a reliance on modified F-16s as surrogate controllers, delaying the operational integration of uncrewed systems. Consequently, the timeline for achieving full-spectrum air dominance in contested environments would slip significantly.
