The ZSU-57-2 can be employed in a ground support role.
Uses a shortened T-54 chassis with thinner armor and only four road wheels.
Fuel drums can be fitted on rear of hull.
Absence of a tracking radar, a night vision device, and an enclosed turret makes this a daylight, fair weather weapon system only.
Auto traverse with manual backup. Uses same ammo as the towed single S-60 AA gun.
Replaced by the ZSU-23-4
- Large square open-topped turret.
- Twin tapering barrels with "pepperpot" muzzle brakes.
- Four road wheels, no support rollers.
Later variants were fitted with a more sophisticated sighting system,
identified by two small ports in forward upper portion of the turret.
- Chinese Type 80
