The DP-27 (Russian: Пулемёт Дегтярёвa Пехотный "Degtyaryov's infantry machine gun") or Degtyaryov machine gun (DP) is a Sovietlight machine gun that fires 7.62×54mmR cartridge, designed by Vasily Degtyaryov.
Service trials starting in 1927, followed by general deployment in 1928. It was the standard Soviet infantry LMG during World War II. With various modifications it was used in aircraft and almost all Soviet tanks as either a flexible bow machine gun or a co-axial one controlled by the gunner. It was improved in 1943 into the DPM, then replaced in 1946 with the belt-fed RP-46.
