"An improvement of the 20.3cm twin gun, it is the No. 3 twin gun.

This model further enhances the originally high-performance heavy cruiser main gun.

This weapon is an excellent 55 caliber main gun for heavy cruisers.

It is an excellent gun, but there is a flame in economic efficiency, it can not be mass-produced as there is a limited supply of prototypes."
