BMD-20

The BMD-20 (GRAU designation 8U33) was a 200 mm multiple rocket launcher (MRL) created by the Soviet Union.

==Overview== Following the success of rocket artillery systems like the Katyusha during World War II, the Soviet Union continued development on such weapons. Development of the BMD-20 began in 1947 and it was accepted into Soviet Army service in 1952. The system was based on a ZIS-151 6×6 truck chassis carrying four rockets in an open steel lattice resting at +9° elevation which could be raised to +60° and traverse 20° to the sides. The launcher is crewed by eight men, three of which are seated inside the cab with the rest seated externally. The windows of the cab are protected by folding metal sheet covers when firing. Once in position, the BMD-20 can be made ready to fire within two minutes.
