The 2-cm Flak 30 was developed from the Solothurn S5-100 (or ST-5). The first production models entered service with the German Navy (Kriegsmarine) in 1934 and the German Air Force (Luftwaffe) in 1935. Eventually, the Flak 30 was used by all branches of the German Army and saw action on all fronts and theaters. The ammunition was fed by a twenty-round magazine. The original sight was a complex reflecting mirror-sight with an integral mechanical course-and-speed calculator known as the Flakvisier 35. Its complexity led to the need to introduce the simplified Linealvisier 21 sight. The Linealvisier 21 was a simple open course-and-speed sight stamped out of sheet-metal. War time conditions led to the final Schwebekreisvisier 30 “cart-wheel” open sight. The basic mount used a triangular platform that was transported on a light two-wheeled carriage. The well-designed carriage enabled the Flak 30 to be dismounted and put into action in a matter of minutes. By 1940, the slow rate of fire of the Flak 30 dictated the need to introduce the Flak 38, capable of 400-rounds-per-minute. The Flak 30 did, however, soldier on until the end of the war due to shortages of the 2-cm Flak 38.
