BM-21 Grad
The BM-21 launch vehicle (Russian: БМ-21 "Град"), a Soviet truck-mounted 122 mm multiple rocket launcher,[1] and a M-21OF rocket[2] were developed in the early 1960s. BM stands for boyevaya mashina, ‘combat vehicle’, and the nickname grad means ‘hail’. The complete system with the BM-21 launch vehicle and the M-21OF rocket has designation as 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 it or developed similar systems.
Description
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 kilometres (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 crew of five men 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-metre (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-metre (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 kilometres (12 mi). Newer high explosive and cargo (used to deliver anti-personnel or antitank mines) rockets have a range of 30 kilometres (19 mi) and more. Warheads weigh around 20 kilograms (44 lb), depending on the type.
The relative accuracy of this system and the number of rockets each vehicle is able to quickly bring to bear on an enemy target make it effective, especially at shorter ranges. One battalion of eighteen launchers is able to deliver 720 rockets in a single volley. However, the system cannot be used in situations that call for pinpoint precision.
Variants
Soviet Union
- BM-21: Original version known as the BM-21 launch vehicle. The launcher unit was mounted on a modified Ural-375D truck chassis.
- BM-21-1: Launch vehicles are mounted on a family of Ural-4320 truck chassis.
- 2B17 or also BM-21-1: This upgrade was presented for the first time in 2003 and was developed by Motovilikha Plants from Perm. The system is fitted with a satellite navigation system NAP SNS, automated fire control system ASUNO, APP laying system and can fire a new generation of rockets with a range of 40 km (25 mi). The truck is the Ural-43201.
- 9P138 "Grad-1": lighter 36-round version, mounted on a six-by-six ZIL-131 chassis. The vehicle with supporting equipment (rockets, transporter 9T450 and re-supply truck 9F380) is referred to as complex 9K55. The 9P138 can only use "short-range" rockets with a range of 15 km (9.3 mi). It used to be known in the West as BM-21b or M1976.
- BM-21V "Grad-V" (Vozdushnodesantiy – 'airborne') (NATO designation M1975): Developed for airborne troops in 1969. A GAZ-66B four-by-four truck chassis is fitted with a 12-round 122 mm rocket launcher. The vehicle is sturdy enough to be air-dropped. Parts of the vehicle such as the canvas cab roof can be taken off or folded down to reduce its size during transit. Like the BM-21, the BM-21V has stabilizing jacks on the rear of the vehicle for support when firing. The launch vehicle has the industrial index of 9P125.
- 9А51 "Prima": 50-round launcher on a Ural-4320 5t chassis. The vehicle together with fire control equipment, the ammunition transporter TZM 9T232M and the new rocket 9M53F is referred to as complex 9K59. Apparently only a small number was produced.
- "Grad-P Light portable rocket system": The complete system comprises a 9P132 single-round man-portable launcher (it can be reloaded and used again), a 9M22M 122mm high-explosive fragmentation rocket and a fire control panel. The system was developed in the middle of the 1960s for North Vietnamese forces at war with the US. It was not accepted for service with the Russian Army, but it was and is still popular with paramilitary and guerrilla forces.
- BM-21PD "Damba" (Protivodiversionnyi): 40-round launcher mounted on Ural-375D or 43201 truck chassis. Developed for protection of naval bases against underwater infiltrations, uses special ammunition PRS-60 (Protivodiversionnyi Reaktivnyi Snaryad). The vehicle together with ammunition transporter is referred to as complex DP-62 "Damba".
- A-215 "Grad-M" – 22-round naval version, entered service in 1978.
Adaptations of the launcher were/are produced by several countries including China, Czechoslovakia, Egypt, Iran, North Korea, Poland and Romania.
Belarus
- BM-21A "BelGrad": This is a modernized version, based on a MAZ-631705 6×6 truck with 425 hp diesel engine TMZ-8424. Between the cab and the launcher there is another pack of 40 rockets. The system was evaluated from 1997 and entered service a couple of years later.
Ukraine
- BM-21M "Grad-U": Ukraine also has switched the original Ural-375 truck with gasoline engine for a new truck with diesel engine, the KrAZ-6322-121. Some vehicles have a longer chassis with 40 additional rockets.
People's Republic of China
- Type 81 SPRL: The People's Republic of China produces the Type 81, which was copied from Russian BM-21s captured in the 1979 Sino-Vietnamese War. After reverse engineering, it entered service with the PLA in 1982 where it is nowadays known as PHZ81. Due to the fact that it is a direct copy, the Type 81 is extremely similar to its Russian predecessor. Its 40 tubes are mounted on a Yan'an SX2150 six-by-six truck, which unlike the original Russian version, has a cab protected by blast shields.
- Type 83 SPRL: This is a 24-round version, based on a Dong Feng truck. The launch tubes are arranged in three rows of 8. The launch vehicle has a total combat weight of 8,700 kilograms (19,000 lb) and can also be used as part of the mine-laying rocket system Type 84. Currently new rockets with ranges between 30 and 40 km (19 and 25 mi) are being developed.
- Type 89 TSPRL: This is basically the 40-round launcher of the BM-21 or Type 81 mounted on a tracked chassis with 520 hp diesel engine. The same chassis is also used for the Type 83 152 mm self-propelled howitzer (PLZ83), the Type 89 120 mm tank destroyer (PTZ89) and several other specialised vehicles. The vehicle has a combat weight of 29.9 short tons (27.1 metric tons) and carries 40 spare rockets. Its current PLA designator is PHZ89.
- Type 90 SPRL: The NORINCO (China North Industries Corporation) Type 90 40-round multiple rocket system is an indigenously designed and built system equipped with an automatic operating and laying system, an electric firing system and an automatically reloadable pack of 40 rockets. It is very similar to the M-77 Oganj but of 122 mm calibre. The chassis used is the Tiema SC2030 6×6 truck. A Type 90 MRL battalion consists of three batteries, each with 6 self-propelled rocket launchers, 6 ammunition re-supply trucks Tiema XC2200 with 80 rockets and a battery command post on a DongFeng EQ-245 6×6 truck.
- Type 90A: Modernised version, based on a Tiema XC2200 6×6 truck chassis and fitted with a modern fire control system with GPS. The command post vehicle can lay and control a number of Type 90A systems by remote control for maximum firepower.
- Type 90B: Latest, digitalised version. The rocket launch vehicle is based on a Beifang Benchi 2629 series 6×6 truck (Mercedes-Benz copy) and has a longer cabin. Each set now also has three forward observer vehicles, based on the armoured WZ551.
Former Czechoslovakia
- RM-70 (raketomet vzor 1970): In 1972 the Czechoslovakian army introduced its own version of the BM-21 launch vehicle (really, launcher unit of the BM-21 LV was used only), designated the RM-70. The launcher unit comprises a bank of 40 launch tubes arranged in 4 rows of 10 and it is mounted on an eight-by-eight 10-ton modified Tatra T813 truck. Unlike the BM-21, the RM-70 has an armoured cab and enough room behind it to allow for the storage of further 40 rockets.
- RM-70/85: Modification of RM-70 launch vehicle on unarmored Tatra T815 truck.
Poland
- WR-40 "Langusta" (eng. European spiny lobster) (wyrzutnia rakietowa means rocket launcher): This is a modern Polish version with a new fire control system (with ballistic computer BFC201 and navigation system Sigma 30) and a modified launcher based on the Jelcz P662D.35G-27 6×6 truck (produced by Jelcz-Komponenty). The first vehicle entered service on March 20, 2007. Probably about half of all 227 Polish BM-21 launchers will be converted into WR-40 launchers. New, modern types of munition were also developed for the launcher: the range is approximately 42 km (26 mi) for fragmentation-HE rockets "Fenix" and 32 km (20 mi) for cargo rockets. The Jelcz P662.D.35 truck with lightly armoured cab is also believed to be the base of a Polish multiple rocket launcher complex, which will possibly be developed in the future.
Egypt
The Egyptians domestically manufacture the rockets "Sakr-36" and "Sakr-18" with a respective range of 36 and 18 km (11 mi), and the latest "Sakr-45" with a superior range of 45 km (28 mi). Rather than a standard HE-Frag round, the Egyptian military prefers a 23-kilogram (51 lb) cluster munition, which can be extremely effective against lightly armored equipment and troop concentrations. Both rockets, as well as the original Soviet models of course, are fired by locally manufactured rocket launchers like the RL-21 (copy of BM-11) and RC-21 (copy of BM-21, similar to the Hadid HM20). The Helwan Machine Tools Company also produces portable systems with one, three, four and eight launch tubes.
Gaza Strip
Since 2006, Hamas has made use of 122mm Grad rockets and 122mm Grad-style copies made in Iran, and others have been Eastern-bloc editions modified to expand their range and lethality.[3] The rockets were believed to be smuggled into the Gaza Strip via tunnels from Egypt.[3] Some of the rockets were of a Chinese Grad variant.[4] Hamas sources said they were pleased by the performance of the Chinese variants of the BM-21 Grad rocket, which demonstrated a far greater range and blast impact than Palestinian made rockets, as well as Russian-origin Grads or Katyushas.[4][5]
On 28 February 2008 at least ten 122mm Grad rockets hit the coastal city of Ashkelon.[6] In other incidents, longer range rockets were used, with twice that of the BM-21 Grad. These longer range rockets were erroneously reported by the media to be also Grad rockets.[6]
In the 2010 attacks on Eilat and Aqaba, nine standard 122mm Grad rockets were used. For the most part, rockets are smuggled into the Gaza Strip through the network of tunnels between the Strip and Egypt.[7]
On 23 February 2011 at least two 122mm Grad rockets were fired at Beersheba hitting and severely damaging a house in a residential area.[8] On 23 March 2011 another two Grad rockets were fired at Beersheba, seriously injuring a civilian.
During the first week of April 2011, Israeli defense forces intercepted and destroyed several Grad rockets fired from Gaza near Ashkelon in southern Israel, using a newly deployed anti-missile system called Iron Dome.[9]
On Saturday August 20, 2011, over 24 Grad rockets were fired from the Gaza Strip towards Israel, landing in Beersheba and Ashdod and killing 1 Israeli. Hamas has claimed responsibility for these attacks.[10]
On Saturday October 29, 2011, the Islamic Jihad fired eight Grad rockets towards Ashdod, Gan Yavne, and west of Be'er Sheva wounding one person and causing light wounds to two more,[11] just hours after Israel Defense Forces soldiers killed Ahmed al-Sheikh Khalil, a commander of the Islamic Jihad and four of its munitions experts.[12] They allegedly were responsible for firing one additional Grad rocket towards Ashdod the previous Wednesday.,[13] in response to attacks from the Israeli Air Force towards a militant squad that was preparing to launch rockets, earlier in the month.[14]
Hamas have used small man-portable single-tube launchers for rockets in attacks against Israel, designated 122 mm 9P132/BM-21-P.[15] The 122 mm Grad rockets used in Gaza have a range of about 40 km (25 mi), and can reach the Israeli towns of Ashdod, Beer-Sheva, Ofakim, Gedera, Kiryat Gat, Ashqelon, Sderot, Rehovot, Kiryat Malachi and Gan Yavne.
Ethiopia
The Homicho Ammunition Engineering Complex produces the rockets while the Bishoftu Motorization Engineering Complex produces the launching tubes and has converted existing trucks to diesel engine. Bishoftu motorization has also produced a six tube launcher to be mounted on light trucks.
North Korea (DPRK)
- BM-11: North Korean 30-tube version. The tubes are arranged in 2 banks of 15; all rockets can be fired in as little as 15 seconds. The basis for the BM-11 system is a Japanese manufactured Isuzu chassis.
- MRL 122 mm M1977: US DIA code for a system that appears to be a direct copy of the BM-21 "Grad".
- MRL 122 mm M1985: This is a more modern version, based on a Isuzu 6×6 truck and probably with a 40-round reload-pack mounted between the cab and the launcher
Iran
D.I.O. from Iran produces copies of the BM-11 and BM-21 systems that can fire the original Soviet rockets as well as the locally developed "Arash" with a range of 20.5 km (12.7 mi). There is also a rocket with a range of 75 km (47 mi).
- HM20 – This is the Iranian version of the BM-21, mounted on a Mercedes-Benz 2624 6×6 truck. The launch pack however consists of 2 packs of 20 tubes. Reportedly there is also a version with an automatic reload-system.
- HM23 – Lighter 16-round version with two packs of 8 launch tubes.
- HMxx – Iranian version of the 30-round BM-11, based on a Mercedes-Benz LA 911B 4x4 truck. Some vehicles are equipped with a light hydraulic crane.
Pakistan
- KRL 122 – Kahuta Research Laboratories from Pakistan have developed a rocket launcher that is very similar to the North-Korean BM-11. The KRL 122 was originally based on an Isuzu truck but later models use the Reo M35 truck. Some sources mention the designator Gadab or Azar. Except for the original Soviet rockets, the "Yarmuk" developed by Pakistan Ordnance Factories can be launched.
Romania
- APR-21 (aruncator de proiectile reactive – rocket launcher): Romanian 21-round launcher (3 rows of 7) mounted on a Bucegi SR-114 four-by-four chassis. No longer used by the Romanian Army but some vehicles have been exported to Nigeria and Croatia. Morocco has the launch pack mounted on a Kaiser M35 truck.
- APR-40: Initially this designator was used for the original BM-21 "Grad" in Romanian service, but Aerostar SA has developed an improved model, based on a DAC-665T six-by-six truck. A slightly improved model, called APRA-40 or 40 APRA 122 FMC is based on the DAC 15.215 DFAEG truck. Each launcher is normally accompanied by a re-supply truck MITC with a 6t crane and a trailer RM13. The system is also used by Botswana, Bosnia, Cameroon, Croatia, Iran, Iraq, Liberia and Nigeria.
- LAROM or LAROM 160: This is an upgraded version that was developed in cooperation with Israel. The launch vehicle is based on the truck chassis DAC 25.360 DFAEG, fitted with two launch packs with each 20 122 mm tubes or 13 160 mm tubes.[16] The LAROM 160 can fire rockets like the LAR Mk.IV with a range of 45 km (28 mi). The system entered service with the Romanian Land Forces in 2002.[17]
South Africa
- Valkiri: This is an improved South African design by Denel using 127 mm rockets.
- Bateleur: A newer, more accurate version of the Valkiri. Based on the Withings (White Stallion) military recovery truck chassis. Also produced by Denel.
