Pentagon tester: F‑35 software upgrades stagnated — no new combat capability fielded last year despite Iran missions

The Pentagon's weapons testing office reports F‑35 software upgrade efforts “stagnated” last year, with no new combat capability delivered even as F‑35s continued to fly missions over Iran. The finding highlights a disconnect between operational employment and software delivery timelines.

Briefing

What Hype is tracking

The tester says upgrades “stagnated” and no new combat capability was fielded last year, reinforcing earlier Pentagon tester concerns about F‑35 software development.
F‑35s are being flown on missions over Iran while the software pipeline lags, increasing operational risk and exposure demonstrated when an F‑35 was damaged over Iran.
The report compounds sustainment and readiness problems — the fleet’s mission‑capable rate fell to ~50% in 2024 — even as the Pentagon moves toward a major additional F‑35 procurement, raising budget, industrial and operational risk.
