U.S. Mark 15/16 19-inch 45 Caliber Turret

3D Model

A fictional 19 inch Naval Turret.

The Mark 15/16 was a “paper only” design proposed for a theoretical U.S. Navy Super Battleship circa 1948. The 19.1-inch gun would have been the largest naval artillery ever built and would have been capable of firing 3 tonn projectiles over 80 miles.
