UK’s £71 billion F-35 programme struggles with readiness, delays and rising costs

Share

The UK’s £71 billion F-35 fighter jet programme is facing serious operational setbacks, with aircraft being mission-ready only one-third of the time. Key issues include a shortage of engineers, spare parts, unexpected corrosion, and delays in weapon integration.

Although the Ministry of Defence has invested £11 billion so far, full programme costs are projected to hit £71 billion by 2069, including operations for 138 aircraft—but excluding weapon costs. A recent National Audit Office report highlights missed economic and strategic benefits due to staffing gaps, infrastructure shortcomings, and procurement delays.

Between October 2024 and January 2025, no jets were mission-ready, and current limitations force British F-35s to use only bombs, making them more vulnerable in combat. Only 48 of the planned 138 F-35Bs have been ordered, with further purchases delayed for financial reasons, now resulting in higher long-term costs and reduced capability.
