The DShK 1938 (

Georgi Shpagin, who later improved the cartridge feed mechanism. It is sometimes nicknamed Dushka (a dear or beloved person) in Russian-speaking countries, from the abbreviation.[15]

Specifications

The DShK is a belt-fed machine gun firing the 12.7×108mm cartridge, and uses a butterfly trigger.[16] Firing at 600 rounds per minute, it has an effective range of 2.4 km (1+1⁄2 mi), and can penetrate up to 20 mm of armor up to a range of 500 m.[17] The DShK has two "spider web" ring sights for use against aircraft. It is used by infantry on tripod mounts or deployed with a two-wheeled mounting and a single-sheet armor-plate shield. It is also mounted on tanks and armored vehicles for use against infantry and aircraft; nearly all Russian-designed tanks prior to the T-64 use the DShK.[18]

History

Requiring a heavy machine gun similar to the M2 Browning, development of the DShK began in the Soviet Union in 1929 and the first design was finalised by Vasily Degtyaryov in 1931.[17][19] The initial design used the same gas operation from the Degtyaryov machine gun, and used a 30 round drum magazine, but had a poor rate of fire. Georgy Shpagin revised the design by changing it to a belt-fed with a rotary-feed cylinder, and the new machine gun began production in 1938 as the DShK 1938.[17][20] The DShK and the American M2 Browning are the only .50 caliber machine guns designed prior to World War II that remain in service to the present day.[21]

During World War II, the DShK was used by the

T-40 amphibious tank.[17] Similar to the PM M1910 Maxim, when deployed against infantry, the DShK was used with a two-wheeled trolley, with which the machine gun weighed a total of 346 pounds (157 kg).[22] In 1944, a much cheaper muzzle brake patterned after the Polish Wz. 35 anti-tank rifle was introduced instead of the complicated early design.[23] After 1945, the DShK was exported widely to other countries in the Eastern Bloc.[16]

In 1946, an improved variant was produced, with a revised muzzle and feeding system. Named the DShK 38/46 or DShK-M, over a million were produced from 1946-1980.[17] The gun was also revised to become more reliable, and easier to manufacture.[24] The new DShK was produced under license in Pakistan, Iran, Yugoslavia, Romania, Poland[25] and Czechoslovakia.[17] Czechoslovak variant, most often encountered on quads, is visually distinguishable by a rectangular muzzle brake.[26] China produced their own variant of the design, designated the Type 54.[27]

After World War II, DShKs were used widely by communist forces in Vietnam, starting with the Battle of Dien Bien Phu in 1954. While not as powerful as anti-aircraft cannons, the DShK was easier to smuggle through Vietnam, Cambodia and Laos.[17] DShKs were a major threat to American aircraft in the Vietnam War,[16] and of the 7,500 helicopters and fixed-wing aircraft lost during the war, most were destroyed by anti-aircraft guns including DShK.[17]

In June 1988, during The Troubles, a British Army Westland Lynx helicopter was hit 15 times by two Provisional IRA DShKs smuggled from Libya, and forced to crash-land near Cashel Lough Upper, south County Armagh.[28]

Rebel forces utilized DShKs in the Syrian civil war, often mounting the gun on cars. In 2012, the Syrian government claimed to have destroyed 40 such technicals on a highway in Aleppo and six in Dael.[29]

The DShK began to be partially replaced in the Soviet Union by the NSV machine gun in 1971, and the Kord machine gun in 1998.[21] The DShK remains in service, although it is no longer produced.[18]

The weapon was used by Ukrainian forces in the

MANPADS have been unable to destroy. As many of the DShKs have been left over from the Soviet Union, they have been both cost-effective and one of the most reliable methods of destroying drones.[30][31][32]
