Some sound comments, but implying the new UK carriers are 'the wrong ships' ignores a whole host of very good arguments for STOL carriers and against the 'cats-and-traps' type (which arguments have been repeated more than once in these comments pages).
Also, referring only to UK air-to-air kills strictly limits your data set - plenty of air-to-air kills have been achieved by supersonic capable aircraft (Indo-Pakistan wars, Arab-Israeli wars, Various US adventures, East Africa, etc)
