   The WS-22 is a Chinese artillery rocket system. It is an improved version of the PR50 Sandstorm MLRS, which was developed specially for export. This artillery system is in service with Bangladesh since at least 2014. A total of 49 systems were delivered to Bangladesh.

   The WS-22 has a similar layout as the previous PR50 Sandstorm. It has two pods of 122 mm artillery rockets and carries two reload pods. However the WS-22 is based on a more mobile chassis.

   Rockets of the WS-22 reportedly have a simple terminal guidance. Range of fire is up to 45 km. Rockets are factory fitted and sealed. The WS-22 launcher can also carry WS-33 missiles with GPS guidance and a range of 70 km, as well as WS-43 loitering munitions with a range of 60 km.

   Double cab of the vehicle accommodates the crew of 5.

   This artillery system has an unusual feature. In traveling order pods with rockets are covered by retractable bows and canvas cover. This helps to disguise the launcher vehicle as a simple logistical vehicle.

   Launcher of the WS-22 is based on a Wanshan chassis with 6x6 configuration. This vehicle was specially designed for military applications and has good off-road mobility.

   The launcher vehicle is fitted with hydraulic crane for self-reloading. The crane is also used to pick up pods from the ground or other vehicles.

   A battery of WS-22 systems includes a meteorological station. If required each launcher vehicle can operate independently.
