"Typhoon, like most British mil ac is numbered sequentially; Typhoon T1, Typhoon F2. Harrier GR3, Harrier T4, Harrier GR 5 et seq."
Ah, sigh.
Darbouy is old enough to remember when we had a proper RAF and none of this pretend Army Bllx.
Ray,
Can you really remember the days before RAF aircraft marks were designated like this? Right back in WWII, we had Spitfire F.VIII, LF.IX,
PR.XIX, Lancaster B.I, Mosquito NF.II, FB.VI etc - the only thing that seems to have changed is that the numbers have been dumbed down from Roman numerals to Arabic (and we've got rid of the nasty B for Bomber designation - G is evidently much more touchy-feely and PC when hurling bombs and missiles onto foreign countries various...)
