RPD machine gun
The RPD (Ruchnoy Pulemyot Degtyaryova), or Degtyaryov light machine gun, is a gas-operated, air-cooled light machine gun chambered for the Soviet 7.62×39mm M43 intermediate cartridge, designed to provide squad-level automatic fire support.[1][2] It features a belt-fed system using 100-round non-disintegrating metal belts housed in a drum magazine, weighs 7.4 kg (16.3 lb) empty, measures 1,037 mm (40.8 in) in overall length with a 521 mm (20.5 in) barrel, and has a cyclic rate of fire of approximately 650 rounds per minute, with an effective range of 800 meters.[3][4][5] Developed by renowned Soviet designer Vasily Degtyaryov starting in 1943 as part of efforts to create weapons for the new intermediate cartridge, the RPD built on his earlier DP-28 pan-fed machine gun but adapted a belt-feed mechanism for sustained fire and improved portability over previous full-power rifle-caliber designs.[6][2] Although prototyped during World War II, it was formally adopted by the Soviet Army in 1944, entered production in 1945, and saw widespread issuance beginning in 1953, filling the role of the standard light machine gun at the platoon level.[3][5] The RPD's simple, robust construction using stamped metal components facilitated mass production, and its fixed barrel with integral bipod allowed effective suppressive fire in infantry tactics, though it lacked quick-change barrel features for prolonged engagements.[6][7] In Soviet service, it remained in use until the early 1960s, when it was largely replaced by the magazine-fed RPK based on the AK-47 platform, but it continues to see active duty in various African and Asian militaries.[6] Notably, the RPD gained prominence during the Vietnam War, where North Vietnamese Army and Viet Cong forces employed it extensively against U.S. troops, often in ambushes and defensive positions.[8][6]Overview
Specifications
The RPD (Ruchnoy Pulemyot Degtyaryova) is a Soviet-designed light machine gun chambered for the 7.62×39mm intermediate cartridge, serving primarily as a squad automatic weapon operated by a single gunner, often assisted by a loader for ammunition handling.[6][3] It employs a gas-operated, long-stroke piston action and feeds from non-disintegrating metal belts housed in a 100-round drum magazine attached to the left side of the receiver.[9][10] Key performance characteristics include a cyclic rate of fire of 650–750 rounds per minute, a muzzle velocity of 735 m/s, and an effective range of 600–800 meters when fired from the integral bipod.[9][4][11] The weapon's sustained fire capability is constrained by barrel heating, with manuals recommending no more than 300 rounds in continuous bursts without a cooling period, due to the fixed barrel design lacking quick-change provisions.[3][2]| Specification | Details |
