ZPU-2

Also known as
  • ZU-2
  • Type 58
  • PKM-2

The ZPU-2 is a Soviet twin 14.5 mm anti-aircraft gun built around two KPV heavy machine guns on a two-wheel carriage. Captured Iraqi examples, Yemeni truck mounts, and Ukraine's Czech-supplied MR-2 Viktor systems show how the Cold War gun shifted from low-altitude air defense into mobile direct-fire and counter-UAV work.

Gun Components

The ZPU-2 is best understood as a mount built around two 14.5 mm KPV-family heavy machine guns rather than as a self-contained missile or cannon system.

Carrier Vehicles

The ZPU-2 family was adapted from towed carriage service to vehicle mounts, from Soviet armored carriers to modern pickup-based air-defense systems.

Its manual sighting, rapid emplacement, and high volume of fire make it a close-range air-defense weapon against low-flying aircraft, helicopters, and drones, while many operators also use it for direct fire against light vehicles and infantry positions. Ukrainian forces have used ZU-23-2 guns in mobile and positional air-defense teams during the 2014 Russia-Ukraine War, Armenian-side losses in the 2020 Nagorno-Karabakh fighting included towed and vehicle-mounted ZU-23 guns, and conflict monitors documented ZU-23 or ZU-23-2-pattern use in Yemen, Tigray, and northern Mali.

U.S. studies tied the gun to North Vietnam's heavy AAA network and Iraqi inventories retained it into the 1990 Gulf War, while later conflict records show legacy KS-19s displayed in Houthi air-defense equipment and repurposed as long-range ground-fire weapons in Nagorno-Karabakh and Ukraine.
