How would USS New Jersey fare alone against Yamato if led by expert officers in gunnery, ship handling, and damage control?
Short answerNew Jersey is favored despite Yamato's 18-inch guns because the American ship would probably hit first and more often, degrading Yamato's ability to reply effectively.
NotesNominal firepower is only one part of the complete fighting system. Accurate early hits against directors, communications, and superstructure can reduce the effectiveness of even very heavy armor and guns. Superior maneuvering could complicate Yamato's firing solution, while strong damage control would help New Jersey remain effective after being hit. The contest remains uncertain on paper, but New Jersey receives the operational advantage in this stipulated scenario.
