2 cm KwK 30

The 2 cm KwK 30 L/55 "(2 cm Kampfwagenkanone 30 L/55)" was a German 2 cm cannon used primarily as the chief weapon of the German light tank the SdKfz.121 Panzerkampfwagen II. It was used in vehicles that saw action in the Spanish Civil War, and the Second World War.

The KwK 30 also served as the basis for the 20 mm C/30, an aircraft version 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, however, and the cannon was not used on other designs.

An improved version the, 2 cm KwK 38 L/55 "(2 cm Kampfwagenkanone 38 L/55)" was used on the SdKfz.121 Panzerkampfwagen II "(Ausf. J models onwards)".
