Nagato-class Battleship



This article refers to the entire Nagato-class; it is not about an individual vessel.

ww2dbaseThe Nagato-class battleships were designed by Japanese Navy Captain Hiraga Yuzuru, thus they were the first Japanese battleships to be designed domestically. They were also the first battleships in the world to mount 410-milimeter guns, making Nagato and Mutsu the most powerful warships of the early 1920s. At the onset of the Pacific War, despite being aged, Nagato was the flagship of the Combined Fleet, aboard which Admiral Isoroku Yamamoto oversaw the Pearl Harbor attack.
