2 cm KwK 30


The 2 cm KwK 30 L/55 ' was a German 2 cm cannon used primarily as the main armament of the German Sd.Kfz.121 Panzerkampfwagen II light tank. It was used during the Spanish Civil War and the Second World War. It was produced by Mauser and Rheinmetall-Borsig from 1935.
The KwK 30 also served as the basis for the 20 mm C/30, an aircraft variant that was mounted experimentally in some Heinkel He 112 fighters and proved to make an excellent ground-attack weapon during the Spanish Civil War. Direct ground-attack was not considered a priority for the Luftwaffe and the cannon was not used on other designs.
An improved version, the 2 cm KwK 38 L/55 ', was used on the Sd.Kfz.121 Panzerkampfwagen II . It was also used on the Sd.Kfz.251/17 Schützenpanzerwagen anti-aircraft vehicle, which had the gun on a pedestal mounting with a small armored turret to protect the gunner. Late war, it was issued as a platoon commander's vehicle to replace the Sd.Kfz.251/10 Schützenpanzerwagen.
