Bismarck,
What is this 'training dilemma' of which you talk? Is it the difficulty of maintaining a ludicrously small cadre of RN fast-jet pilots using entirely the same training system as teh RAF but without anywhere to send them if they don't quite cut it as single-seat and no career prospects above Commander?
My solution - the RN gets 2 CVF, the RAF flies and maintains all the jets. best value for defence all round.
