What happened to Project Ark Royal, and what would catapult-and-arrested aircraft add to the Royal Navy?
Short answerProject Ark Royal was only a thought experiment; a working CATOBAR conversion would chiefly add aircraft such as E-2 Hawkeye and long-range uncrewed strike platforms, but changing from the established F-35B fleet would be costly.
NotesIn the discussion, Project Ark Royal is described as a thought experiment rather than an approved conversion program. A working CATOBAR system would permit aircraft such as E-2 Hawkeye, the first purchase proposed in the reply. F-35C and long-range uncrewed strike aircraft are further possibilities. Existing F-35B procurement would make a change of fighter type difficult, and a mixed fleet would bring additional support costs and complexity.
