The BM-21 launch vehicle (Russian: БМ-21 "Град"), a Soviet truck-mounted 122 mm multiple rocket launcher, and a M-21OF rocket were developed in the early 1960s. BM stands for boyevaya mashina, ‘combat vehicle’, and the nickname grad means ‘hail’.
History
Initial development work on the Soviet 122 mm artillery rockets commenced during the late 1940s to supplement and eventually to replace the Great Patriotic War era (1941-45) 82 mm and 132 mm Katyusha MRS from the mid-1950s onwards. The State Research and Production Association Splav at Tula was the main design bureau under the leadership of A Ganichev, with the final development being completed in 1963. The number of 122 mm MRS types developed gradually until, by 1964, the standard version had become the 122 mm BM-21 Grad ('hail') series with its 40-tube launcher array.
The BM-21 Grad is carried on ZIL-131, Ural-375D or Ural-4320 6 × 6 trucks, although there have been many other types of vehicle and launcher combinations. These include the 122 mm BM-21V (Grad-V) 12-launcher system mounted on GAZ-66 (4 × 4) trucks and the 122 mm 9P132/BM-21-P man-portable single-tube launchers for use by special forces. The main producer of the 122 mm BM-21 Grad rocket series is Splav at Tula.
