   The BM-21 Grad (hail) multiple launch rocket system entered service with the Soviet Army in 1963. It was produced for a long period of time in large quantity both for the Soviet Army and for export customers. Currently the BM-21 Grad is in service with more than 30 countries. It is the most widely used artillery rocket system in the world. There are numerous variants, copies and modifications of this vehicle.

   The BM-21 Grad has 40 launching tubes for 122-mm rockets. The standard rocket with a HE-FRAG warhead is 2.87 m long and weights 66.6 kg. Warhead itself weights 18.4 kg. It also fires rockets fitted with incendiary, chemical, smoke, illumination or cluster warheads. Cluster warheads contain anti-tank or anti-personnel submunitions. A number of specialized warheads were developed for this vehicle. A full salvo of the BM-21 Grad covers area of 0.8 -1 hectares.

   Vehicle is prepared to fire in three minutes. The BM-21 can launch rockets directly from the cab or remotely from the vehicle. It is possible to launch rockets without preparing the firing position. This feature ensures brief reaction time. The Grad can be packed up and ready to move in two minutes.

   The BM-21 is based on the Ural-375D 6x6 high mobility truck. Vehicle is powered by the ZiL-375 petrol or diesel engine, developing 180 horsepower. Later Grads were mounted on newer Ural-4320 and ZiL-131 trucks. A launcher pack can be mounted on any other acceptable chassis type.

   The BM-21 is reloaded manually. Reload rockets are carried in escorting utility truck. It takes less than 10 minutes to reload the launching vehicle.
