The Mark 42 5"/54 Caliber Naval Gun is a naval gun (naval artillery) mount used by the United States Navy and other countries. It consisted of the Mark 18 gun and Mark 42 gun mount.
United States naval gun terminology indicates the gun fires a projectile 5 inches (127.0 mm) in diameter, and the barrel is 54 calibers long (barrel length is 5" × 54 = 270" or 6.9 meters.) In the 1950s a gun with more range and a faster rate of fire than the 5"/38 caliber gun used in World War II was needed. The 5"/54 Mk 42 is an automatic, dual-purpose (air / surface target) gun mount. It is usually controlled remotely from the Mk 68 Gun Fire Control System, or locally from the mount at the One Man Control (OMC) station.
The self-loading gun mount weighs about 60.4 long tons (61.4 t) including two drums under the mount holding 40 rounds of semi-fixed case type ammunition. The gun fires 31.75 kg (70.0 lb) projectiles at a velocity of 2,650 ft/s (807.7 m/s). Maximum rate of fire is 40 rounds per minute. Magazine capacity is 599 rounds per mount. It was the last major caliber gun system with the ability to be fired from local control by an operator in the gun mount.
