A specially modified three-legged ZU-23-2 autocannon is used as the base for the BTR-DG airborne SPAAG. It can also be mounted on the roof of the MT-LB multi-purpose tracked APCs. The gun is often mounted on trucks for use in both anti-aircraft and direct fire support roles. The ZU-23-2 first entered service with the Soviet Army in 1960. produces rounds and fuses for the 2A7 and 2A14 guns. Not only the gun itself but also the ammunition is produced in several countries. Penetration 30 mm RHA at 1000 m range and 30 degree impact angle (from perpendicular), tracer burn time >2.5 s. HE fragmentation round with a reduced HE charge due to the space taken by the tracer tracer burn time 5 seconds.Ī Polish sub-caliber armour-piercing round with tracer, introduced in 2008. HE fragmentation round with nose fuzes incorporating self-destruct mechanism. Penetration 15 mm RHA at 1000 m range and 30 degree impact angle (from perpendicular), tracer burn time 5 seconds. The following table lists the main characteristics of some of the available 23x152B ammunition used in 23 mm AA guns:īlunt AP steel core, with incendiary charge inside windshield cap. Due to different loadings and primers the ammunition is not interchangeable, however: ammunition of the anti-aircraft cannon can be identified from its steel casings, ammunition for the aircraft cannon having brass cases instead. The 23 mm AA gun utilizes the same 23x152B case as the wartime VYa aircraft autocannon. The weapon is known in the Finnish forces colloquially as Sergei. In USSR and later Russia the most frequently used towing vehicles for it were GAZ-66 4x4 trucks and GAZ-69 4x4 light trucks. The ZU-23-2 can be towed by a number of different vehicles.
However, these versions never entered service. In another similarity to the ZPU series, single-barrel and four-barrel versions of the ZU-23 were also developed. 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. The cannon carriage is based on the earlier ZPU-2 anti-aircraft twin heavy machine gun, which mounted two KPV 14.5×114mm heavy machine guns.

Tulamashzavod Joint Stock Company is offering to upgrade the 2A14 guns to the 2A14M standard with a barrel life of 10,000 rounds instead of 8,000 rounds. Each weapon is normally provided with two replacement barrels as part of its standard equipment. Normally, once each barrel has fired 100 rounds it becomes too hot and is therefore replaced with a spare barrel. The fumes created by firing the weapon are partially removed through the side openings in the barrels. Each of the ammunition boxes is located on the side of the twin autocannon and each carries 50 rounds. The ammo is fed by a conveyor belt from two ammunition boxes. It also has a straight-tube telescope T-3 for use against ground targets such as infantry as well as unarmored or lightly armoured vehicles. The weapon is aimed and fired manually, with the help of the ZAP-23 optical-mechanical sight which uses manually entered target data to provide limited automatic aiming. The autocannon can be prepared for firing from the march position in 30 seconds and in emergency can be fired from the traveling position. While in this position the wheels are moved aside. The ZU-23-2 (2A13) mounts two 23 mm autocannons on a small trailer which can be converted into a stationary mount for firing the guns. ĭevelopment of this weapon into a self-propelled anti-aircraft gun led to the ZSU-23-4 Shilka. The ZU-23 has also been produced under licence by Bulgaria, Poland, Egypt and the People's Republic of China. In the Soviet Union, some 140,000 units were produced.

While the former was eventually dropped, the ZU-14 was selected and, after some modifications, entered series production. In 1955, KBP presented the single-barrel ZU-1 and the twin-barrel ZU-14. It was designed to engage low-flying targets at a range of 2.5 km as well as armoured vehicles at a range of two kilometres and for direct defence of troops and strategic locations against air assault usually conducted by helicopters and low-flying airplanes. The ZU-23-2 was developed in the late 1950s. ZU stands for Zenitnaya Ustanovka (Russian: Зенитная Установка) – anti-aircraft mount. The ZU-23-2, also known as ZU-23, is a Soviet towed 23×152mm anti-aircraft twin-barreled autocannon. Sudanese conflict in South Kordofan and Blue Nile Towed 23 mm Anti-Aircraft Twin Autocannon
