# KPV heavy machine gun

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. 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.

## Mechanics

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.

## Versions
### KPVT

The version for use in armored vehicles is called the KPVT (Russian: КПВ танковый, romanized: KPV tankovy, lit. 'Tank-Mounted KPV'). KPVT is used for armored vehicle installations, boats, movable and stationary mounts and various antiaircraft mounts. It features a shorter receiver and a heavier barrel jacket. The KPVT also uses a 50-round belt instead of the original 40-round belt. KPVTs are the primary armament of the wheeled BTR-60PB/70/80 series armored personnel carriers and BRDM-2 armored reconnaissance vehicles. It is intended for fighting against lightly armored targets, weapons systems and light shelters at the distances of up to 3,000 m (9,800 ft), as well as air targets at distances up to 2,000 m (6,600 ft).
The distance at which the bullet retains lethal force is 8 km (5.0 mi). The maximum flight range of the bullet is 9 km (5.6 mi).

### Naval armament

The naval twin mount had several versions:
* 2M-5 was for motor torpedo boats.
* 2M-6 was a machine gun turret for armored gunboats.
* 2M-7 was for patrol and mine sweeping boats.
The single mount was called the "14.5 mm MTPU" (Russian: 14,5-мм МТПУ, an initialism for 14,5-мм морская тумбовая пулемётная установка, '14.5 mm Naval Machine Gun Column Mount'). The 14.5 mm MTPU is intended for combat against armored surface, coast and air targets. It is mounted on decks of boats and can defeat surface and coast targets with a range of 3,000 m (9,800 ft) horizontally and 2,000 m (6,600 ft) vertically against low flying planes.

### ZPU

The ZPU (Russian: ЗПУ, an initialism for Зенитная пулемётная установка, 'Anti-Aircraft Machine Gun Mount') is a towed anti-aircraft gun based on the KPV. It entered service with the Soviet Union in 1949 and is used by over 50 countries worldwide.
* ZPU-1 single-barreled mount.
* ZPU-2 twin-barreled mount.
* ZPU-4 quadruple-barreled mount.

#### Mountain version

* ZGU-1 single-barreled pack mount (Russian: ЗГУ, romanized: ZGU, an initialism for Зенитная горная установка, 'Mountain Anti-Aircraft Mount').
