Man what ever happened to the Sea Harrier Fa.2 and Sea Harrier FRS.1? Those are true fighters.
Withdrawal of funding and creationg of a joint RAF/RN "Joint Harrier Force" using GR7/9.
Why can't the JSF use a ski jump?
I expect it can, but I'm unsure as to whether it could perform the rolling VTO as performed by the Harrier on small carriers. That's why the UK is having to build new carriers.
