The Chinese WZ550 Tank Destroyer is a wheeled 4×4 version of the ZSL92 mounting a traversable weapon station. This consists of x4 ready-to-launch HJ-9 Anti-Tank Missiles, which are laser guided on to their targets. The station mounts a periscope optical day sight (7km range) and has a thermal channel.
The vehicle has a crew of three (driver, commander, and weapon operator). The driver has three periscopes and a light-enhanced night vision. The crew is protected by a collective NBC protection system and an automated fire suppression system. A 4-barrel 75mm smoke grenade launcher is fitted on either side of the vehicle. The vehicle has a combat weight of 13.75t, and is powered by a 320hp turbo-charged diesel. The maximum road speed is 95km/h.
The vehicle is believed to have entered PLA service around 1999.
