How would an Alaska-class large cruiser fare against Yamato?
Short answerBadly; Yamato's protection, 18-inch guns, and radar-assisted fire control are expected to overwhelm Alaska.
NotesThe comparison exposes the danger of treating every unusually large cruiser as a battleship equivalent. Alaska carried formidable cruiser armament, but Yamato combined much heavier protection with 18-inch guns. Yamato also possessed a form of radar-assisted fire control, improving the chances that the larger battery could be used effectively. Alaska is therefore expected to be sunk rather than fight on equal terms.
