The US Navy installed three of this type of 8"/55 caliber triple-gun turrets on the following heavy cruisers of World War II fame:

  • USS Northampton CA-26
  • USS Chester CA-27
  • USS Lousiville CA-28
  • USS Chicago CA-29
  • USS Houston CA-30
  • USS Augusta CA-31
  • USS Portland CA-33
  • USS Indianapolis CA-35

 

These turrets are not suitable for USS New Orleans CA-32 or USS Astoria CA-34 or the other members of the New Orleans class. They had a differently shaped triple-gun turret.

These 250-ton turrets carried three Mk.9 guns, later upgraded to Mk.14 guns.  Please use your favorite brass barrels or your kit's parts.

From Wikipedia: "The 8"/55 caliber gun (spoken "eight-inch-fifty-five-caliber") formed the main battery of United States Navy heavy cruisers and two early aircraft carriers. United States naval gun terminology indicates the gun barrel had an internal diameter of 8 inches (203 mm), and the barrel was 55 calibers long (barrel length is 8 inch × 55 = 440 inches or 11 meters).

"Mark 9: These built-up guns weighed about 30 tons including a liner, tube, jacket, and five hoops. A down-swing Welin breech block was closed by compressed air from the gas ejector system. Loading with two silk bags each containing 45-pounds (20 kg) of smokeless powder gave a 260-pound (120 kg) projectile a velocity of 2800 feet per second (850 m/s). Range was 31,860 yd (29,130 m) at the maximum elevation of 41 degrees.

"Mark 14: These guns were similar to Mark 9, with the same shell weight and maximum range, with a smaller chamber and rifling twist increased from 1 in 35 to 1 in 25 in a chromium-plated bore."
