The 14"/50 caliber gun was a naval gun mounted on New Mexico and Tennessee-class battleships. These ships also featured the first "three-gun" turrets, meaning that each gun in each turret could be "individually sleeved" to elevate separately (however, they could be linked so they would elevate as a unit, similar to the triple turrets on other ...

The U.S. Navy had the 16"/50-caliber Mark 2 guns left over from the canceled Lexington-class battlecruisers and South Dakota-class battleships of the early 1920s. However it was already apparent that the Mark 2 was too heavy to arm the North Carolina and new South Dakota (1939) battleship classes which had to adhere to the 35,000 ton standard displacement set by the Second London Naval Treaty.
However, the two treaty-era battleships fired their shells at a lower muzzle velocity, which made their plunging fire superior to that of the 16"/50 caliber gun.

The National Museum of the United States Navy, or U.S. Navy Museum for short, is the flagship museum of the United States Navy and is located in the former Breech Mechanism Shop of the old Naval Gun Factory on the grounds of the Washington Navy Yard in Washington, D.C., United States.
The gun was designed in 1939, and a prototype was tested in 1942. Unlike previous guns, such as the 16"/45 caliber guns used on the North Carolina class, which were completely made and assembled at the Naval Gun Factory in Washington D.C., the forgings for the Mark 8 were manufactured at the Midvale and Bethlehem Steel corporations.
