Would V/STOL be the only practical way to regenerate naval air power quickly after wartime losses?
Short answerIt would probably be the fastest route if aircraft production survived, because smaller carriers need less specialized equipment, but it may not be the best permanent solution.
NotesIf aircraft production already exists, V/STOL avoids the time needed to build and install catapults and arresting gear. Smaller, simpler carriers can also be completed more quickly than full CATOBAR ships. That makes the system attractive after a navy has lost most of its aviation and needs aircraft back at sea during the same war. This emergency advantage still leaves long-term questions about payload, range, airborne early warning, and fleet flexibility.
