Which cruiser classes were best suited for conversion into fleet carriers during the 1930s and 1940s?
Short answerBritish Town-class and some large American or Japanese cruisers were plausible, with Tone a stronger candidate than the squat Deutschland design.
NotesFor Britain, the Town class emerges ahead of the County class as the most promising cruiser conversion. American heavy cruisers with three or more main turrets also provide enough hull length and volume to consider. Among Japanese ships, the Tone class looks plausible, whereas the Deutschland design is too squat for an attractive flight-deck conversion. These are only hull candidates: the following discussion explains why pilots, aircraft, escorts, and training still prevent a navy from converting every suitable cruiser.
