Why did the Royal Navy not convert an Admiral-class battlecruiser into an aircraft carrier?
Short answerThe early-1920s Royal Navy lacked sufficient senior backing for the idea, especially under Beatty, even if design work or a usable hull may briefly have existed.
NotesBeatty did not strongly support carriers during the early 1920s and accepted the Fleet Air Arm's transfer to the Royal Air Force, though he later recognized the error. That institutional climate made it unlikely that the Royal Navy would preserve an unfinished Admiral-class hull for conversion. The surviving evidence offers circumstantial signs that Cammell Laird studied large carrier and strike-carrier ideas before Ark Royal. A connection with abandoned Admiral-class conversion work remains a plausible explanation rather than a documented conclusion.
