The American-made members of the Big 7, the Colorado-class, employed these early 16 inch main gun turrets as their standard armament. These three battleships stood next to the Japanese Nagato and Mutsu as well as the Nelson-class of the Country of Black Tea, as the Big Seven. The name ship, Colorado, as well as her sisters that were once destroyed at Pearl Harbour and later refloated, will once again devote themselves to the war in the Pacific Ocean.
