The KPV heavy machine gun (Russian: КПВ, romanized: KPV, an initialism for Крупнокалиберный пулемёт Владимирова, Krupnokaliberny pulemyot Vladimirova, 'Vladimirov's Large-Caliber Machine Gun') is a Soviet designed 14.5×114mm-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 large and heavy. It was later redesigned for anti-aircraft use, as it showed excellent results as an AA gun against low flying aircraft, with a range of 3,000 m (9,800 ft) horizontally and 2,000 m (6,600 ft) vertically.^[4] It was used in the ZPU series of anti-aircraft guns. Its size and power also made it a useful light anti-armour weapon on the BTR series of vehicles and the BRDM-2 scout car.

The KPV was a heavy machine gun developed by S. V. Vladimirov. It was developed in 1944 and adopted in 1949. It combines the rate of fire of a heavy machine gun with the armor-piercing capabilities of antitank rifles and was designed to combat lightly armored targets, firepower and manpower of the enemy located behind light cover, as well as to be an anti-aircraft machine gun. The muzzle energy of the KPV reaches 31 kJ. For comparison, the 12.7 mm Browning M2HB machine gun has up to 19 kJ (14,000 ft⋅lbf) with a 660 gr (43 g) bullet traveling at 3,080 ft/s (940 m/s) manufactured by PMC, the 20 mm ShVAK aircraft mounted gun has about 28 kJ (21,000 ft⋅lbf). It is one of the most powerful machine guns ever used by the Soviet and later Russian armed forces. The development of the machine gun began in 1944. The 14.5×114mm M41 cartridge can be used with high explosive incendiary - tracer (HEI-T) or armor-piercing incendiary (API) bullets. The KPV is air-cooled and fitted with a barrel with a hard chrome plated bore. It uses a short recoil operation system with gas assistance and a rotary bolt. It can be fed with the 40-round metallic belt from either the left or right side. The barrel can be removed by turning the prominent latch on the forward end of the receiver and pulling on the barrel's carrying handle.

The Emirati remote weapon station IGG-RWS14 uses the KPV machine gun.^[7]
