An improved version of a twin-gun main battery for battleships that was 100% domestically developed by the artillery department of the Kure Naval Arsenal. Although fictional, it's supposed be a modified battleship main armament with better plating, rate of fire, a further improved firing system, and which has been optimised for Nagato-class main force battleships as well as the Ise-class. Especially on the K2 Nagato-class battleships after their large-scale remodelling it'll unfold its full potential.


Unbuildable. January 2019 ranking reward. Can be obtained by upgrading a 41cm Triple Gun Mount Kai.
