Nevertheless, the C/30 became the primary shipborne light AA weapon and equipped a large variety of German ships. Disappointingly, it proved to have feeding problems and would often jam, which was offset to some degree by its undersized 20 round-magazine which tended to make reloading a frequent necessity. The C/30, featuring a barrel length of 65 calibres, had a fire rate of about 120 rounds per minute. The gun fired the "Long Solothurn", a 20 × 138 mm belted cartridge that had been developed for the ST-5 and was one of the more powerful 20 mm rounds. The original Flak 30 design was developed from the Solothurn ST-5 as a project for the Kriegsmarine, which produced the 20 mm C/30. The Germans fielded the unrelated early 2 cm Flak 28 just after World War I, but the Treaty of Versailles outlawed these weapons and they were sold to Switzerland. It was produced in a variety of models, notably the Flakvierling 38 which combined four Flak 38 autocannons onto a single carriage. It was not only the primary German light anti-aircraft gun but by far the most numerously produced German artillery piece throughout the war. The Flak 30 ( Flugzeugabwehrkanone 30) and improved Flak 38 were 20 mm anti-aircraft guns used by various German forces throughout World War II. 2cm Flak 30 in travel configuration at SaumurĢ cm Flak 38, Gebirgsflak 38, Flakvierling 38įlak 30: 280 rpm (cyclic)/120 rpm (practical)įlak 38: 450 rpm (cyclic)/180 rpm (practical)
