There was a rather expensive project which looked at installing CATOBAR on the QE class carriers. An angled flight deck as well as new catapult system would be required. It was deemed too expensive and would most likely have resulted in only on carrier being built and used.
So no navalised 'Phoons, F35Cs or less than useless French Rafael's.
God bless the Royal Navy.
