Naval artillery

From Wikipedia, the free encyclopedia

(Redirected from Naval gun)

Naval artillery or naval rifles refers to warship-mounted guns used in naval warfare for attacking other vessels, bombarding targets on shore (naval gunfire support), or for anti-aircraft. Conversely, the term may be used as a descriptor about the naval rifles used in land batteries for anti-shipping area denial purposes. Smaller-bore guns are sometimes referred to as deck guns, such as on Coast Guard cutters and destroyers.

The crowning achievement of naval artillery was the Dreadnought-era battleship. The dominance of the modern battleship was from about 1906 to the start of World War II during which typical main armament rose from 12-inch (305 mm) guns to 15-inch (381 mm) guns or 16-inch (406 mm) guns with consequent increase in range and shell firepower. The largest naval guns ever mounted were the 18.1-inch (460 mm) guns used on the Japanese Yamato class battleships, firing a 1,460 kilogram (3,219 lb) projectile to a maximum range of 42,000 metres (45,930 yards).

The limitations to the range of the battleships' heavy guns meant that they were effectively replaced by the naval aircraft. The secondary and anti-aircraft weapons have fallen to the range and flexibility of guided missiles and naval guns have been reduced in importance though never completely replaced. Modern warships such as destroyers and frigates are typically only armed with one or two naval guns.

In naval vernacular the word "cannon" is never used to describe naval guns.
