The ZPU (Russian: зенитная пулемётная установка, meaning "anti-aircraft machine gun mount") is a family of towed anti-aircraft gun based on the Soviet 14.5×114mm KPV heavy machine gun. It entered service with the Soviet Union in 1949 and is used by over 50 countries worldwide.

Quadruple (ZPU-4), two double- (ZPU-2 and ZU-2) and single-barreled (ZPU-1) versions of the weapon exist.


The 1931 ZPU for 7.62 mm machine guns

The first dedicated Soviet mount for anti-aircraft machine guns was developed around 1928 by Fedor Tokarev and was adopted for service in 1931. It was a base for mounting up to four 7.62 mm PM M1910 (Russian Maxim) guns. This was also called a ZPU, although the name М-4 was also assigned to it. It served the Soviet armed forces in all major conflicts until 1945.[1]


Development of the ZPU-2 and ZPU-4 began in 1945, with development of the ZPU-1 starting in 1947. All three were accepted into service in 1949. Improved optical predicting gunsights were developed for the system in the 1950s.

All weapons in the ZPU series have air-cooled quick-change barrels and can fire a variety of ammunition including API (B32), API (BS41), API-T (BZT) and I-T (ZP) projectiles. Each barrel has a maximum rate of fire of around 600 rounds per minute, though this is practically limited to about 150 rounds per minute.

The quad-barrel ZPU-4 uses a four-wheel carriage similar to that once used by the obsolete 25 mm automatic anti-aircraft gun M1940. In firing position, the weapon is lowered onto firing jacks. It can be brought in and out of action in about 15 to 20 seconds, and can be fired with the wheels in the traveling position if needed.

The double-barrel ZPU-2 was built in two different versions; the early model has large mud guards and two wheels that are removed in the firing position, and the late model has wheels that fold and are raised from the ground in the firing position.

ZPU-2 turned out to be too heavy for the Airborne Troops, so a new UZPU-2 (later redesignated as ZU-2) was developed from ZPU-1.

The single-barrel ZPU-1 is carried on a two-wheeled carriage and can be broken down into several 80-kilogram pieces for transport over rough ground.

Versions of the weapon are built in China, North Korea and Romania.

The series was used during the Korean War by Chinese and North Korean forces, and was later considered to be the most dangerous opposition to U.S. helicopters in Vietnam. Later it was used by Morocco and the Polisario Front in the Western Sahara War. It was also used by Iraqi forces during Operation Desert Storm and again in Operation Iraqi Freedom. In 1974 the Cyprus National Guard artillery batteries used their ZPU-2's against the Turkish air force. In the Russian military, it was replaced by the newer and more powerful ZU-23 23 mm twin automatic anti-aircraft gun.

The type has seen widespread use by all sides in the 2011 Libyan civil war and Syrian Civil War often mounted on pickup-truck technicals with plenty of videos showing the gun engaging different targets.[2][3]

The Lebanese Army has mounted the ZPU-2 and ZPU-4 on M113 armored personnel carriers to create armored self-propelled AA vehicles.


Rounds are also produced by Bulgaria, China, Egypt, Poland, and Romania.
