Three-gun turrets were specifically designed for the Iowa class battleships of the U.S. Navy, and later intended for the even larger Montana class battleships.  Each turret mounted three 16-inch/50 caliber Mark 7 naval rifles.  This was the largest naval turret and gun used operationally by any US Navy warship.

These barrels are precisely scaled to match a set of 4 Montana class turrets available separately (click here).  The barrels were scaled from official US Navy drawings.  They are not 3D-printed copies of any resin or plastic model ship parts and therefore are likely to be differently shaped and sized than the turrets found in your plastic or resin kit.  Some adjustment to your kit's parts or any aftermarket items may be necessary for best fit.

A set of 5"/54 cal. Mk.41 twin-gun mounts (turrets) is also available separately.

This turret set is suitable for Montana class battleships:

  • BB-68 USS Ohio
  • BB-69 USS Maine
  • BB-70 USS New Hampshire
  • BB-71 USS Louisiana 


Regarding the Mark 7 gun, from Wikipedia: "These guns were 50 calibers long—or 50 times their 16-inch (406 mm) bore diameter which makes the barrels 66.6 feet (20 m) long, from breechface to muzzle. Each gun weighed about 239,000 pounds (108,000 kg) without the breech, or 267,900 pounds (121,517 kg) with the breech. They fired projectiles weighing from 1,900 to 2,700 pounds (850 to 1,200 kg) at a maximum speed of 2,690 feet per second (820 m/s) with a range of up to 24 miles (39 km). At maximum range the projectile spent almost 1½ minutes in flight. Each turret required a crew of 79 men to operate. The turrets themselves cost US$1.4 million each, to which the cost of the guns had to be added."
