 == History ==
-The 21-KM's story begins in 1926 with a 37mm anti-gun prototype made by Rheinmetall. The Soviet Union, needing an anti-gun but lacking the know-how to make one, turned Germany and the two nations agreed in secret to have German companies develop Soviet artillery designs to bypass the Treaty of Versailles armament restrictions. The result was the 37mm anti-tank gun M1930 (1-K), the Soviet Union's first dedicated anti-tank weapon and an early proof of concept of what would become the [[PaK L/45 (37 mm)|PaK L/45]]. Shortly after the 1-K began production in the Soviet Union in March of 1932 V. Bering at Factory No. 8 created the 19-K 45mm anti-tank gun M1932 which scaled up the gun barrel to 45mm for the economical reason that the Soviets had it in stock. The 19-K would be developed into the [[45 mm/46 21-K (45 mm)|21-K]] as an anti-aircraft weapon for the Soviet Navy, but the gun would be superseded by the automatic [[70-K (37 mm)|70-K]] as the main naval anti-aircraft gun in 1942. The production of the 21-K however continued and that same year the No. 172 Plant in Motovilikha made the 45mm anti-tank gun M1942 (M-42) for the Red Army which was effectively a longer barrelled variant of the 19-K. The longer barrelled was also adopted by the Soviet Navy as the 21-KM and by this point, production completely switched to monobloc barrels from the original built-up gun barrels. Production ended in 1947 just like the 21-K itself.
