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.〔http://www.wehrmacht-history.com/heer/panzer-armaments/2-cm-kwk-30.htm〕 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). ==Ammunition== 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.〔http://www.http://www.panzerworld.com/armor-penetration-table.htm〕 * PzGr.39 (Armour Piercing) (Can go through 23mm of armor at 100 meters and 14mm of armor at 500 meters) * PzGr.40 (Armour Piercing Composite Rigid) (Can go through 40mm of armor at 100 meters and 20mm of armor at 500 meters) * s.Pz.B.41 (Armour Piercing Composite Rigid) * 2 cm Sprgr. 39 (High Explosive) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2 cm KwK 30」の詳細全文を読む スポンサード リンク
