This topic covers the automatic guns which were used in the different navies from the arrival of light machine guns on board to the development of modern rapid-firing guns to combat fast-flying aircraft. It is in three parts, starting with the Maxim and Vickers Maxin guns then follows the Bofors, Oerlikon and Breda guns to finish with rifle-calibre machine guns. With the development of small, fast torpedo boats, it became necessary for a ship to counter attacks using easily-trained, rapid-firing guns of sufficient calibre and range to hit and stop torpedo boat attack before they can launch their torpedoes. In addition, as the performance of aircraft improved after the First World War, it became necessary to have a gun with similar properties for anti-aircraft defence. Rifle-calibre machine guns were adopted on board ship in the light of the experience with machine guns on land. Their role was to ward off boarders, to clear the decks of enemy ships and were a major component of naval landing parties. Once again, as aircraft attacks became more and more a risk, so multi-barrelled machine guns were placed up in the superstructure of ships. |
