A large-caliber battleship main gun developed and operated in the United States as the main armament of their battleships.
It was installed on the Nevada-class battleships, which was a continuation of the standard battleship, and their predecessors, the New York-class battleships.
The standard low-speed battleship, the Nevada-class, which employs large firepower and a concentrated defense system, was also equipped with a triple-barreled version of the same gun.
