History
The Soviet Union, at its start, lacked the capability of providing infantry the necessary firepower to combat the potent threat of airpower. While other nations were moving ahead with large caliber machine guns after World War I, the Soviet Union only began requesting a similar weapon system in 1925.[1][2]
Unsatisfied with foreign examples, the Soviet Union sought to create an indigenous design of a heavy machine gun. The first step was the cartridge, which resulted in the 12.7x108 mm cartridge. For the weapon design, the Soviet Union asked Vasily Alekseyevich Degtyaryov, who had designed the DP machine gun, to produce a machine gun for the new cartridge. Degtyaryov delivered in 1930 his new machine gun, which was essentially the DP machine gun scaled up and fed by a 30-round magazine designed by A. Kladov. The machine gun was designated the DK, or Degtyaryov Krupnokalibernyj (Degtyarov Large Caliber).[1][2]
The DK was put into production in 1933. The weapon was typically mounted on a Koleshnikov universal mount, which had a wheeled carriage for transportation and firing at ground targets, and the mount's trails can be used as a tripod to engage aircraft.[1] The weapon saw use on armored cars, light tanks, and on small naval vessels.[2]
However, issues arose from the 30-round magazine the DK was equipped with, which restricted the overall firing rate of the weapon due to reloads. As such, by 1935 the weapon type was discontinued. However, another designer by the name Georgiy Shpagin would work with the DK to produce a belt-feed mechanism for the weapon in 1937. The weapon, a collobration effort between Degtyaryov and Shpagin, would eventually be adopted in 1939 as the DShK mod.38, which would go on as the predominate version of the weapon.[1]
