The RM-70 Multiple Launch Rocket System is a Czechoslovakian army version and the heavier variant of BM-21 Grad Multiple Launch Rocket System (MLRS) providing enhanced performance over its parent artillery system that was introduced in 1972. RM-70 replaced the Ural-375D 6x6 track by a Tatra 813 8x8 truck as carrier platform for the 40 rocket tubes launcher. The new carrier vehicle provides enough space for carrying 40 additional 122mm rockets pack for reload. Nevertheless, RM-70 performance remains near the same as Grad even in terms of vehicle's speed and range. This rocket launcher can fire both individual rounds and volleys, principally by means of indirect fire. It is designed for concentrated fire coverage of large areas (up to 3 hectares in one volley) by high explosive fragmentation shells.

The fire is robust with almost 256 kg of explosives used in one volley of 40 rockets.

The vehicle is provided with a control device of the adjustment of the pressure of the tires (to allow its adaptation to the nature of the traversed ground) and, if necessary, with a blade bulldozer BZT intended to arrange the position of battery or to release the obstacles.

RM-70 was developed in Czechoslovakia achieving initial operational capability (IOC) with its Army in 1972. Originally, it was sold to East Germany. After the Soviet Union collapse and the split of Czechoslovakia into the Czech Republic and Slovakia was sold to several nations in Africa, America, Asia and Europe.

In December 2000 Slovak Ministry of Defense and Dhiel BGT Defence started RM-70 Modular German-Slovak modernization project. RM-70 Modular allows this artillery system to launch both 122mm and 227mm rockets used on the M270 MLRS. This way the system turned into fully NATO interoperable. Slovak Republic signed for 26 upgraded artillery systems with the first one delivered on May 20, 2005. RM-70 Modular is being offered as an upgrade for RM-70 owners.
