Overview
- Defense Department data show the F-35 fleet averaged about 50% availability in 2024, roughly 17 points below the minimum threshold.
- The report attributes the shortfall primarily to maintenance and sustainment problems linked to Lockheed Martin.
- Governance lapses in the F-35 Joint Program Office included unclear, unenforceable availability targets and inconsistent property and inspection practices.
- Sustainment delays and spare-parts bottlenecks constrained deployment and training capacity, reducing combat readiness.
- About €1.7 billion was paid to Lockheed Martin during the underperformance period, prompting pressure for stricter oversight and payment terms tied to results.
