5"/25 caliber gun
From Wikipedia, the free encyclopedia
The 5"/25 caliber gun (spoken "five-inch-twenty-five-caliber") was the standard anti-aircraft gun for United States Washington Naval Treaty cruisers. The gun was also mounted on pre-World War II battleships and aircraft carriers until replaced by the standard dual-purpose 5"/38 caliber gun.[1] United States naval gun terminology indicates the gun fired a projectile 5 inches (127 mm) in diameter, and the barrel was 25 calibers long. (barrel length is 5" x 25 = 125" or 3 meters)[2]
The gun weighed about 2 tonnes and used fixed ammunition (case and projectile handled as a single assembled unit) with a 9.6-pound (4.4 kg) charge of nitrocellulose propellant to give a 54-pound (24 kg) projectile a velocity of 2100 feet per second (640 m/s). Ceiling was 27,400 feet (8352 meters) at the maximum elevation of 85 degrees.[3]
