DShK دوشکا gun

The requirement for a heavy machine gun appeared in 1929. The first such gun, the Degtyaryov, Krupnokalibernyi (DK, Degtyaryov, Large calibre), was built in 1930 and this gun was produced in small quantities from 1933 to 1935.
The gun was fed from a drum magazine of only thirty rounds, and had a poor rate of fire. Shpagin developed a belt feed mechanism to fit to the DK giving rise, in 1938, to the adoption of the gun as the DShK 1938. This became the standard Soviet heavy machine gun in World War II.
