The arrival of three F-35B jets means the UK has now taken delivery of 30 jets. With one aircraft lost in an accident and three test jets in the US, there are now 26 of the type in operational service in the UK. Seven more will arrive in 2023 with an expectation that all of the 47 in the first batch will be delivered by the end of 2025. Note that it would have been 48 if one didn’t crash.
