F-35 Combat Use Highlights Readiness Gaps as European Fleet Expands and Sustainment Bill Reaches $13.7B

Air Force officials say the F-35 demonstrated combat value during Middle East operations, even as GAO found three in four aircraft unable to fly a full mission and sustainment needs reached $13.7 billion. Europe received more than three dozen jets in the past year, while Switzerland’s procurement faces rising costs and contract scrutiny.

Briefing

What Hype is tracking

Combat employment is strengthening the F-35’s operational case, but reported readiness shortfalls show that fleet size and combat effectiveness remain constrained by spare-parts and logistics capacity.
The fleet has outgrown the logistics system designed for 800 aircraft, with a $13.7 billion remediation requirement creating a significant long-term sustainment burden.
More than three dozen F-35s entered Europe over the past year, while Switzerland’s experience highlights procurement risks around fixed-price protections, cost growth and delivery delays.
