M1992

   This self-propelled anti-aircraft gun is based on the ZSU-23-4 Shilka chassis. This vehicle was first observed in 1992. It was developed as a replacement for the older twin 37-mm SPAAG. It is worth mentioning that in the 1980s North Korea produced a significant amount of self-propelled artillery, mating towed artillery tubes with chassis already in service. Unlike most North Korean adaptations, the M1992 may have improved performance over the original type. This anti-aircraft artillery system was produced in quantity, however it is unknown how many of them were built.

   The M1992 SPAAG spots a noticeably taller turret, comparing with the Shilka. It is fitted with two 30-mm automatic guns. Maximum rate of fire is 800 rounds per barrel. Estimated effective range against air targets is about 3 000 m. The M1992 uses HEI-T rounds. This self-propelled anti-aircraft system can also be used against ground targets.

   Fire target surveillance radar and fire control system remains from the ZSU-23-4. It has a tracking range of 6 - 10 km, depending on the target's altitude.

   Armor of the M1992 protects occupants from small arms fire and artillery shell splinters.

   It is suggested, that this SPAAG has a crew of four, including commander, gunner, radar operator and driver.

   Vehicle is powered by a V-6P1 diesel engine, developing 280 hp. It is also fitted with auxiliary power unit, which powers all systems, when the main engine is turned off.
