Crazy or not, that IS the state of the world's aircraft carriers. GB went with gas turbines on
HMS Queen Elizabeth because they are cheaper than nukes, easier to repair and not fraught with the difficulties of nukes on a carrier. Look at all the problems the French have with the
Charles de Gaulle. Only the US has been able to perfect nukes for carriers.
Incidentally, 'turbine' is pronounced to rhyme with 'combine' or 'haybine', NOT like the thing a Sikh wears on his head, a 'turban'.
