The Chinese PGZ88 SPAAG is a hybrid of the Type 69-III AKA Type 79 Medium battle Tank and the Type 65 twin-37mm towed anti-aircraft gun.
The Type 65 was developed in the 1960s as a successor to the Soviet M1939 single-barrel 37mm AAA (produced in China as Type 55). The weapon was designed primarily to engage airborne targets within the distance of 8,500m (or slant range of 3,500m), but it can also be used against land or water surface targets.
The fire control consists of the target search/rangefinder radar, optical sighting, electro-optical director, ballistic computing device, and identification of friend or foe (IFF) transmitter/receiver. The search radar has a detection range of 15km and altitude of 3,000m.
The Type 76 high-explosive round with tracer in single or burst mode from one or both barrels, with a muzzle velocity of 1,000m/s. The vehicle carries 1,000 rounds inside its turret with the fire-control radar mounted on the roof.
