The cannon carriage is based on the earlier ZPU-2 anti-aircraft twin heavy machine gun, which mounted two KPV14.5×114mmheavy 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 also developed. However, these versions never entered service.
The ZU-23-2 can be towed by a number of different vehicles. In USSR and later Russia the most frequently used towing vehicles for it were GAZ-664x4 trucks and GAZ-69 4x4 light trucks.[8]
The weapon is known in the Finnish forces colloquially as Sergei.[12]
Ammunition
The 23mm AA gun utilizes the same 23x152B case as the wartime VYa aircraft autocannon. 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.[13] The following table lists the main characteristics of some of the available 23x152B ammunition used in 23mm AA guns:
Not only the gun itself but also the ammunition is produced in several countries. In Bulgaria, the company ARCUS Co. produces rounds and fuses for the 2A7 and 2A14 guns.[17]
Indonesia – 4 system ZUR-23-kg-I as part of the "Kobra" AD system for the TNI-AD[75] + 18 Giant Bow twin 23mm gun as part of the Giant Bow II AD system for the TNI-AD[76]
Iran - 1000 supplied from 1967 to 1970.[77] 300.[78]
