This triple-barreled cannon was one of the main cannons used in the land of the pastas by battleships.
Boasting a fast-firing 50 caliber barrel, it was considered to have some of the highest firepower among mid-range combat equipment.
As for firepower, it's very similar to the Yamato Class 46cm cannons, and holds its rankings among them.
Some of the main problems were its accuracy and durability, but with modernization, its accuracy has been improved over time.
