UK's F-35 fleet can only perform its required missions one third of the time, report reveals
UNITED KINGDOM, JUL 11 – UK F-35 fleet can perform all missions only one third of the time due to engineering shortages, spare parts delays, and corrosion, with whole-life costs now estimated at £71 billion, NAO says.
- The National Audit Office published a report today revealing the UK F-35 fleet can perform all required missions only about one-third of the time in 2024.
- This poor performance stems from delays, lack of trained personnel, infrastructure gaps, and overdue integration of key weapons, delaying full capability until the 2030s.
- The UK has received 38 F-35B jets with 37 in service as of mid-2025, aiming for 138 aircraft by 2069, but the delivery pace lags due to cost saving decisions and global programme issues.
- The report states the whole-life programme cost is about £71 billion including personnel and support, and Gareth Davies said the aircraft offer improved capability and economic benefits, but these are underrealized.
- The report urges the Ministry of Defence to focus its resources to enhance operational capability and address critical shortages to maximize the benefits of the F-35 programme for the UK.
