What might the Imperial Japanese Navy have built if it chose carriers and smaller battleships instead of Yamato?
Short answerPossibly two carriers and two capable 35,000-ton battleships, with other cruiser construction also relieved.
NotesThe Yamato program absorbed industrial resources that might otherwise have produced cruisers and other fleet units. Redirecting the effort could plausibly yield two carriers and two capable 35,000-ton battleships. Removing Yamato's demands would also relieve pressure on cruiser construction and might allow Japan to proceed with some planned large or super-cruisers. The counterfactual exposes the opportunity cost of concentrating so much capacity in a few prestige hulls.
