i thought the french pulled out of the euro fighter because they said it could not be navalised and thats why the rafale came about and it was to do with the position of the engine air intakes i beleive
You thought wrong.
The French had a requirement that the aircraft had to be able to operate off the Foch, which limited it in size/range etc. Nobody else was willing to accept the consequent limitations, so they had to go off on their own. That was well before the design was finalised and, only subsequently, was it optimised without having to take into account carrier capability.
