What if the United States publicly designed a carrier able to operate medium bombers before World War II?
Short answerIt would trigger counterbuilding, including a faster Japanese Shinano and oversized British Ark Royal-style carriers.
NotesA public American program for a medium-bomber carrier would trigger counterbuilding. Japan might accelerate Shinano and adapt her for larger aircraft. Britain could answer with enlarged Ark Royal-like ships able to operate Mosquito-sized aircraft, possibly with armored flight decks. The result would be a carrier arms race led chiefly by the United States and Britain before the war. More British carriers entering service would alter the opening balance even if the exact designs differed.
