The ZU-23, better known as ZU-23-2, is a towed Soviet short-range air defense cannon. ZU stands for Zenitnaya Ustanovka - anti-aircraft mount.
ZU-23-2 was developed in late 1950s and entered service with the Soviet Army in 1960. It mounts two 2A14 23 mm autocannons on a small trailer which can be converted into a stationary mount for firing the guns. The cannon can be prepared for firing from the march position in 30 seconds and in emergency can be fired from traveling position. The weapon is aimed and fired manually, with the help of a ZAP-23 optical-mechanical sight which uses manually entered target data to provide some automatic aiming. It also has a straight-tube telescope for use against ground targets such as troops and lightly armoured vehicles.
The cannon carriage is based on the earlier ZPU-2, which mounted two 14.5 mm machine guns. ZU-23-2 can be identified by different placement of the ammunition boxes (at right angles to the gun carriage) and by muzzle flash suppressors. In another similarity to the ZPU series, single-barrel and four-barrel versions of the ZU-23 were developed. However, these versions never entered service.
Development of this weapon into a self-propelled anti-aircraft gun (SPAAG) lead to the ZSU-23-4 Shilka. ZU-23-2 is often mounted on trucks for use in both anti-aircraft and fire support roles. It can also be mounted on the roof of the BTR-D airborne vehicle.
Cheap, easy to operate and reasonably effective, the ZU-23-2 is still used by the Russian Army and by more than 20 other armies. The Finnish military nickname for the weapon is Sergei. There are also non-ex-Soviet produced versions of the weapon. One example is the Polish ZUR-23-2TG, which has improved sights and is armed with "Grom" missiles in addition to the autocannons. Another is the Finnish 23 ItK 95, which is often vehicle mounted, like a technical.
