History Note:
The 20mm Oerlikon was among the most important light anti-aircraft weapons used by Allied forces during World War II. Mounted aboard Royal Navy warships, merchant vessels and coastal installations, it proved highly effective against low-flying aircraft and dive bombers. By 1942 these guns had become standard defensive armament across much of the Allied fleet and saw action in virtually every theatre of war.
