Contributions

• In 1927, the Red Army was equipped with the 7.62 mm light machine gun called ДП, or DP-28 (Russian: Дегтярёва Пехотный Degtyaryov's infantry (machine gun)). This design also led to
  • Two aircraft machine guns: ДА (DA) and ДА-2 (DA-2) (Дегтярёва Авиационный)
  • A tank machine gun: ДТ, or DT (Дегтярёва Танковый)
• Degtyaryov also designed a few models of submachine guns, the best of which would be adopted by the Soviet Army in 1934 (modernized in 1940) as the ППД PPD-40 (from Пистолет-пулемёт Дегтярёва, Degtyaryov's submachine gun).

• In 1930, Degtyaryov designed his 12.7 mm large-caliber machine gun, the ДК, or DK (Дегтярёва Крупнокалиберный). In 1938, this machine gun was upgraded by Georgi Shpagin and called ДШК (DShK) (Дегтярёва Шпагина Крупнокалиберный).

• In 1939, Degtyaryov designed his heavy machine gun called ДС, or DS (Дегтярёва Станковый). The DS-39 was issued to the Red Army and used in the Russo-Finnish War of 1939-1940. The belt feed mechanism damaged the cartridge cases and the gun was found too complicated and liable to malfunctions and was withdrawn from service.

• During the Great Patriotic War, the Soviet Army adopted Degtyaryov's 14.5 mm anti-tank rifle the ПТРД, or PTRD (Противотанковое Ружьё Дегтярёва) and 1944 light machine gun.
