The PGZ-04 is an upgraded version of the earlier PGZ-95 series self-propelled integrated gun-missile Anti-Aircraft (AA) system serving the People's Liberation Army (PLA) of China. The vehicle is locally designed, developed, and manufactured while featuring more potent short-ranged Surface-to-Air Missiles (SAMs) integrated with Rapid-Fire (RF) automatic cannons around a central turret component. The tracked nature of the vehicle allows it to cut across country easily enough while also keeping up with the main fighting mechanized force. The PGZ-04 is fielded in number alongside Chinese PLA mechanized units as an airspace deterrent measure - particularly against low-flying threats such as attack helicopters.
The vehicle was designed by the Northwest Institute of Mechanical & Electrical Engineering of Xianyang (Shaanxi), China.
The chassis sports a conventional track-and-wheel drive arrangement which sees six double-tired roadwheels to a hull side, a front-mounted drive sprocket and rear-mounted track idler. No track-return rollers are featured. The engine sits at front-right with the driver's position at front-left and the commander directly behind. The turret is seated over the aft-section of the hull roof and consists of a 360-degree traverse capability with elevation built into the gun and missile components. At the turret's base are two banks of four (for a total of eight) smoke grenade dischargers to creating a self-screening action. The CLC-1 S-Band pulse-Doppler search-and-tracking radar system (of 11 kilometer range) is mounted to the turret's roof and a Fire-Control Computer, laser rangefinder, TV tracking camera, and Electro-Optical (EO) director are part of the system's overall makeup. The rear of the hull is squared off and houses a square-shaped access door for the crew of three.
A diesel-powered engine unit allows for road speeds of 53 kmh to be reached out to a range of 450 kilometers. The vehicle has an overall length of 6.71 meters, a beam of 3.2 meters, and a height of 3.4 meters while weighing in at 22,500 kilograms.
Standard armament is 4 x 25mm autocannons along with 2 x 2-tubed QW-2 short-ranged Surface-to-Air Missile (SAM) launchers. Two guns, as well as two missile launch tubes, are fitted to either side of the turret component. Coupled with its search and tracking equipment, the PGZ-04 is optimized for the low-level aircraft deterrence role.
The latest PLA version if the "PGZ-04A" production model.
