   Recently a number of new artillery rocket systems appeared in China. One of them is a medium-range SR-4. It is a further development of the Type 81, which in turn is a clone of the Soviet BM-21 Grad. The Type 81 is in service with Chinese Army and some other countries. In 2012 Thailand ordered 4 of these artillery systems. All vehicles were delivered in 2013.

   The main role of this artillery system is to engage area targets, such as concentration of troops and equipment, airfields, command posts, and other important targets.

   The SR-4 has two pods with 20 tubes each. It fires 122-mm artillery rockets. These rockets were originally developed for the Soviet BM-21 Grad and are widely used around the world. Rockets with various warheads are available, including HE-FRAG, smoke, incendiary and illumination. Also there are cluster warheads with anti-tank or anti-personnel submunitions. Maximum range of fire with newly developed rockets is up to 50 km.

   The SR-4 launcher is based on Shaanxi SX2190KA 6x6 heavy-duty military truck. This truck is in service with the Chinese army.

   Each SR-4 launcher vehicle is escorted by associated reloading vehicle, which carries pods with reload rockets and is fitted with a crane. It seems that used rocket pods can be also reloaded manually by the crew. Reloading usually takes place remotely from firing position in order to avoid counter-battery fire.

   Normally launcher vehicles operate in batteries, however each vehicle can also operate autonomously.
