This set of three-gun turrets (more properly called "gunhouses") represents the enormous main battery of the Iowa class battleships.  This set is suitable for models of USS Iowa BB-61, USS New Jersey BB-62, USS Missouri BB-63, USS Wisconsin BB-64 and the incomplete USS Kentucky BB-65 and USS Illinois BB-66.


These 3D-printed turrets are designed from official Navy drawings and may be differently shaped and sized than the parts in your ship model kit.  Some adjustment to your kit's parts or other aftermarket products like photoetch may be required for best fit. 


  • dimensions scaled from scans of original builder's blueprints and confirmed by measurements taken from actual gunhouses on the real ships
  • barrels integrated with a trunnion permitting the modeler to set the barrels to any realistic elevation from +45 degrees to -2 degrees, just like the real turrets
  • open armored rangefinder viewport shutters
  • rangefinders with telescopic sights visible through the open shutters of the armored covers
  • armored rangefinder hexhead bolt and domed screw details
  • detailed rooftop periscopes
  • asymmetrical underside ventilation trunks (as-built 1943-1945 configuration)
  • detailed turret-bottom crew access hatches
  • turret roof plate screws, properly numbered, sized and located

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."

These turrets were specifically designed for the Iowa class battleships of the U.S. Navy, and later intended for the even larger Montana class battleships, 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.  The Iowa class carried three of these huge turrets.  The Montana class would have carried four.  This turret is not accurate for the earlier North Carolina class and South Dakota class battleships, whose turrets were slightly shorter.
