SU-23
The SU-23 ( Russian ЗУ-23 , due to the English transcription also ZU-23 ) is a rifled anti-aircraft gun from Soviet production.
technology
Development of the SU-23 began in the late 1950s. The gun was to serve to defend troop accumulations and stationary facilities against low-flying aircraft and helicopters, and to a limited extent also as an anti-tank gun against ground vehicles. The gun consists of two parallel-mounted 23-millimeter machine guns of the type 2A14 on a wheeled chassis which is primarily intended for the attachment to a truck. Development models also included single and four-barrel variants, which, however, were never used in the armed forces. The chassis is based on the previous model SPU-2 (ZPU-2). In the combat position, the wheels are folded down so that the underside of the gun rests on the ground. The conversion from marching to combat function should be possible within 30 seconds, in emergencies also the firing of the gun that is still on its wheels.
Target acquisition and firing of the SU-23 are manual. The gun can be rotated 360 degrees. The opto-mechanical sighting device "SAP-23" offers limited aiming support. A telescopic sight is available for firing ground targets. The ammunition is fed to both tubes with belts from a 50-round container. The gun uses armor-piercing and high-explosive projectiles. The main difference between the cannon and the SPU-2 is its flash hider .
In 1960 the SU-23 entered service with the Soviet Army . There it was not only used as a towed vehicle, but also permanently mounted on various trucks and the MT-LB and BTR-DG armored personnel carriers and used from there.
The gun is currently in use in various variants by around 20 armed forces.
