A triple gun mount made for battleships by the land of pasta.
A 50-caliber gun with a high rate of fire. It was most powerful at medium-short ranges.
In addition, the range is on par with the 46cm cannons of the Yamato-class.
There were issues with the cannon's durability. The spread of its fire was also wide, so it had poor accuracy.
