IF, and it's a big IF, the F-35B doesn't work out ( I had the privelige of working with Test Pilot Graham Tomlinson - G.T, and he wouldn't bother with a naff project, + this thing has heaps of money behind it ! ) there are some people who think a marinised Typhoon would do the trick.
A, This makes a Harrier II+ look very easy,
B, We all know how great the Spitfire was, but the Seafire markedly less so; my Father was there at the Salerno landings ( that's more like crash landings - ask him ! ).
Naval, carrier aircraft have to be designed for the job - and as I would bet my left wotsit that we won't have any more money - like cat n'trap - spent on the carriers, things like F-18's, old or new aren't going to happen; hence my suggestion of Harrier II+.
