Common card · No. 384218

The 16"/45-caliber Mark 6 gun is a naval gun designed in 1936 by the United States Navy for their Treaty battleships. It was introduced in 1941 aboard their North Carolina-class battleships, replacing the originally intended 14"/50-caliber Mark B guns and was also used for the follow-up South Dakota class. These battleships carried nine guns in three three-gun turrets. The gun was an improvement to the 16"/45-caliber Mark 5 guns used aboard the Colorado class, and the predecessor to the 16"/50-caliber Mark 7 gun used aboard the Iowa class.
