Was switching to STOVL a mistake when CATOBAR carriers and the F-35C offer better range?
Short answerNot necessarily. For a small fleet with several ski-jump-capable platforms, STOVL can create more operational redundancy even if the F-35C is the stronger individual aircraft.
NotesThe CATOBAR-STOVL choice is a fleet-design problem rather than a competition between individual aircraft. A British plan combining Queen Elizabeth-class carriers with ski-jump LHD replacements for Ocean, Albion, and Bulwark could have created several platforms able to operate F-35Bs. Damage or maintenance affecting one ship would leave other compatible decks available. For a country with limited hull numbers, that redundancy can outweigh the F-35C's performance advantage.
