"The first purely domestically produced battleship gun was developed at Kure Naval Yard Gunnery Division. Calibered at 41cm, which slightly exceeds 16in (40.6cm), it was the largest battleship gun until Yamato-class' 46cm gun. Nagato and Mutsu, being equipped with this gun, were well-known nationally as members of World's Big Seven."

Developed for the IJN's first 'Eight-Eight Fleet Program' in 1910, in which Japan initially intended to build eight battleships and eight armored cruisers. The Washington Naval Treaty of 1922 scrapped the various plans for other ships to carry this gun, leaving the Nagato-class as the sole class. 


Buildable. Stock equipment of Nagato (And Nagato Kai), Mutsu (And Mutsu Kai) and all Kongou-Class Kai and Kai Ni.
