understood but we have the Typhoon for this task
Typhoon was never planned as the Tornado F3 replacement, it was designed as the AST 403 Jaguar/Harrier replacement, but became the F3 replacement when they were retired and they were already on order. The RAF really wanted a long range 2 seat interceptor for over ocean intercepts.
The Tempest is sized for the long range interceptor role both for the UK, and because that is also exactly what Japan is interested in acquiring, so its size reflects the original role rather than that of the Eurofighter as a CR dogfighter.
