The KPV heavy machine gun (Krupnokaliberniy Pulemyot Vladimorova - rus. Крупнокалиберный Пулемет Владимирова - КПВ) is a Soviet designed 14.5×114 mm-caliber heavy machine gun, which first entered service as an infantry weapon (designated PKP) in 1949. In the 1960s the infantry version was taken out of production because it was too big and heavy. It was later redesigned for anti-aircraft use, because it showed excellent results as an AA gun against low flying planes, with a range of 1500m and was used in the ZPU-4, ZPU-2 and ZPU-1 anti-aircraft guns. Its size and power made it a useful light anti-armour weapon on the BTR series of vehicles and BRDM-2 scout car. The version for use in armoured vehicles is called the KPVT (tankoviy, 'tank').

The development of the machine gun began in 1944. The cartridge can be used with High Explosive Incendiary - Tracer (HEI-T) or Armour-Piercing Incendiary (API) bullets, and they have approximately twice the energy of a normal 12.7 mm (.50 BMG) projectile. The KPV is air-cooled and fitted with a chromed barrel. It uses a short recoil operation system with gas assistance and a rotary bolt. It can be fed with the 40-round belt from either the left or right side.
