Aside from being slower, lighter, and smaller, what were the other differences? The South Dakota class also had the slightly less capable version of the 16 inch guns, at 45 calibers long, and also crew accommodations were smaller compared to the Iowa class, since the South Dakota class was smaller at 680 feet long, but how cramped was it, was it unreasonably cramped? Also did the South Dakota have air-conditioning for the crew quarters, for the tropics where the ships operated in, otherwise it can get unbearably hot and humid inside the ship. Or is it only for the officer accommodations and the bridge? Also can the South Dakota take on the Yamato one on one? Considering that the South Dakota class has the better fire control system and has a lot higher probability of landing the first shot from way out?
