How badly would five radar-equipped autoloading cruisers maul Yamato in a Guadalcanal night battle?
Short answerThey could sink her if they closed the range, using superior radar direction and overwhelming rapid-fire volume despite the smaller shells.
NotesThe scenario depends on the cruisers reaching the close ranges typical of a Guadalcanal night action. Five ships with autoloading 9-inch-class guns would deliver an exceptional volume of fire under more advanced radar control than Yamato possessed. Individual shells lack battleship striking power, but repeated close-range hits could wreck upper works, sensors, and vulnerable systems until cumulative damage becomes fatal. Yamato's own guns remain dangerous, yet the numerical and fire-control imbalance makes her loss plausible.
