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 SdKfz.121 Panzerkampfwagen II light tank . It was used in vehicles that saw action in the Spanish Civil War, and the Second World War. It was produced by Mauser and Rheinmetall-Borsig from 1935.[2]

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). Also used on the Sd.Kfz. - 251/17 Schützenpanzerwagen (2 cm). Anti-aircraft vehicle armed with a 2 cm KwK38 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 (3.7 cm PaK).


The 2 cm KwK 30 used the 20 x 138B cartridge. Average penetration performance established against rolled homogenous steel armor plate laid back at 30° from the vertical.[3]
