The 3"/23 caliber gun (spoken "three-inch-twenty-three-caliber") was the standard anti-aircraft gun for United States destroyers through World War I and the 1920s. United States naval gun terminology indicates the gun fired a projectile 3 inches (76 mm) in diameter, and the barrel was 23 calibers long (barrel length is 3" x 23 = 69" or 1.75 meters.)[1]
The built-up gun with vertical sliding breech block weighed about 531 pounds (241 kg) and used fixed ammunition (case and projectile handled as a single assembled unit) with a 13-pound (6 kg) projectile at a velocity of 1650 feet per second (500 m/s).[2] Range was 10100 yards (9235 meters) at 45 degrees elevation.[2] Ceiling was 18000 feet (5500 meters) at the maximum elevation of 75 degrees.[2]
Surviving United States destroyers built with 3"/23 caliber were rearmed with dual-purpose 3"/50 caliber guns during World War II. The 3"/23 caliber gun was also mounted on submarine chasers, armed yachts, and various auxiliaries.[2] Some major warships carried 3"/23 caliber guns temporarily while awaiting installation of quad 1.1"/75 caliber guns.[2]
The 3"/23 caliber gun was mounted on:
- Caldwell class destroyers[3]
- Wickes class destroyers[3]
- Clemson class destroyers[3]
- Town class destroyers[4]
