Would catapult-equipped Queen Elizabeth carriers need to be larger?

Would Queen Elizabeth-class carriers need to be larger if they used catapults and operated F-35Cs?

A larger hangar is favoured, although folded F-35Cs would occupy less width than F-35Bs. Space for complete squadrons and fixed-wing airborne early-warning aircraft also matters.

Aircraft need enough hangar length and width to fit in complete rows and squadron-sized groups. The forward section of the existing Queen Elizabeth hangar is described as accommodating about half a squadron, with a modest extension potentially making room for a full one. Tentative figures put the folded F-35C at about 31 feet wide against the F-35B's 35-foot wingspan, despite the C reaching about 43 feet with its wings extended. A Hawkeye-type airborne early-warning aircraft would occupy more space than a Merlin helicopter, which also fits the anti-submarine role. Keeping such an aircraft on the flight deck is rejected because it would complicate maintenance. The design question therefore concerns the entire air group and its support needs, as well as the fighters.
