Yamato cannot change battleship perception alone

If Yamato had better 100 mm dual-purpose guns, could she have forced a battleship fight and changed postwar views of battleships?

Probably not; numbers and air support mattered more, and later battleship memory was reshaped well after the war.

Yamato's problem included the weight of aircraft attacking a battleship that lacked proper air support, not only the quality of her anti-aircraft fit. British, American, and Soviet observers understood that battleships and air support were stronger together than either arm operating alone. Even a battleship fight would not necessarily change later perceptions, which were heavily shaped by retrospective arguments from the 1970s and 1980s onward.
