notes"The BM-11 is a North Korean version of the Russian BM-21 The BM-21 "Grad" (Russian: БМ-21 "Град", lit. 'hail') is a Soviet truck-mounted 122 mm multiple rocket launcher. The weapons system and the M-21OF rocket which it fires evolved in the early 1960s and saw their first combat use in March 1969 during the Sino-Soviet border conflict. BM stands for boyevaya mashina (Russian: боевая машина – combat vehicle), and the nickname grad means "hail". The complete system with the BM-21 launch vehicle and the M-21OF rocket is designated as the M-21 field-rocket system. The complete system is more commonly known as a Grad multiple rocket launcher system. In NATO countries the system (either the complete system or the launch vehicle only) was initially known as M1964. Several other countries have copied the Grad or have developed similar systems. The M-21 field rocket system with a BM-21 launch vehicle (122 mm multiple rocket launcher (MRL) system) entered service with the Soviet Army in 1963 to replace the aging 140 mm BM-14 system. The launch vehicle consists of a Ural-375D six-by-six truck chassis fitted with a bank of 40 launch tubes arranged in a rectangular shape that can be turned away from the unprotected cab. The vehicle is powered by a water-cooled V-8 180 hp gasoline engine, has a maximum road speed of 75 km/h (47 mph), road range of up to 750 kilometers (470 mi), and can cross fords up to 1.5 m (4 ft 11 in) deep. The original vehicle together with supporting equipment (including the re-supply truck 9T254 with 60 rockets) is referred to by the GRAU index "9K51"; the launcher itself has the industrial index of "2B5". In 1976, the BM-21 was mounted on the newer Ural-4320 six-by-six army truck. The three-member crew can emplace the system and have it ready to fire in three minutes. The crew can fire the rockets from the cab or from a trigger at the end of a 64-meter (210 ft) cable. All 40 rockets can be away in as little as 20 seconds, but can also be fired individually or in small groups in several-second intervals. A PG-1M panoramic telescope with K-1 collimator can be used for sighting. The BM-21 can be packed up and ready to move in two minutes, which can be necessary when engaged by counter-battery fire. Reloading is done manually and takes about 10 minutes. Each 2.87-meter (9 ft 5 in) rocket is slowly spun by rifling in its tube as it exits, which along with its primary fin stabilization keeps it on course. Rockets armed with high explosive-fragmentation, incendiary, or chemical warheads can be fired 20 kilometers (12 mi). Newer high explosive and cargo (used to deliver anti-personnel or antitank mines) rockets have a range of 30 kilometers (19 mi) and more. Warheads weigh around 20 kilograms (44 lb), depending on the type. The number of rockets that each vehicle is able to quickly bring to bear on an enemy target makes it effective, especially at shorter ranges. One battalion of eighteen launchers is able to deliver 720 rockets in a single volley. The system has lower precision than typical artillery and cannot be used in situations that call for pinpoint accuracy. It relies on a large number of shells dissipating over an area for a certain hit rate on specific targets. Nonetheless, because of the short warning time for the impact of the whole volley, the BM-21 is still considered an effective weapon."
