</ref> ''BM'' stands for ''boyevaya mashina'' ({{langx |ru| боевая машина}} – [[combat vehicle]]), and the nickname {{lang|ru-Latn|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 and 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 the '''M1964'''. Several other countries have copied the Grad or developed similar systems. In Russian service its intended replacement is the [[9A52-4 Tornado]]. Many similar 122&nbsp;mm MLRS systems are made by different countries based on the BM-21 Grad.

== Description ==
[[File:ЗРК Град парад.jpg|left|thumb|A BM-21-1 launch vehicle during a military parade in Yekaterinburg, May 2009.]]

The M-21 field rocket system with a BM-21 launch vehicle (122&nbsp;mm multiple rocket launcher (MRL) system) entered service with the Soviet Army in 1963 to replace the aging 140&nbsp;mm [[BM-14]] system. The launch vehicle consists of a [[Ural-375D]] 6x6 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 V8 180&nbsp;hp [[gasoline engine]], has a maximum road speed of {{convert|75|km/h|mph|abbr=on}}, a road range of up to {{convert|750|km|mi|sp=us}}, and can cross fords up to {{convert|1.5|m|ftin|abbr=on}} deep. The original vehicle together with supporting equipment (including the resupply 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]] 6x6 army truck.{{citation needed|date=May 2022}}

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 {{convert|64|m|ft|adj=on|sp=us}} cable. All 40 rockets can be away in as little as 20 seconds, and can be fired individually or in small groups in several-second intervals. A PG-1M panoramic telescope with a K-1 [[Collimated beam|collimator]] can be used for sighting.{{citation needed|date=May 2022}}

Each {{convert|2.87|m|ftin|adj=on|sp=us}} 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 {{convert|20|km|mi|sp=us}}. Newer high explosive and cargo rockets (used to deliver anti-personnel or antitank mines) have a range of {{convert|30|km|mi|sp=us}} and more. Warheads weigh around {{convert|20|kg|lb}}, depending on the type.{{citation needed|date=May 2022}}

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 gun artillery and cannot be used in situations that call for pinpoint accuracy. It relies on a large number of shells impacting over an area for a certain hit rate on specific targets. Because of the short warning time for the impact of the whole volley, the BM-21 is still considered an effective weapon.{{citation needed|date=May 2022}}

== Operational history ==
The Grad saw its first combat use in March 1969 during the [[Sino-Soviet border conflict]].

Their use, in conjunction with the [[130 mm towed field gun M1954 (M-46)|M-46]], during ''[[Operation Savannah (Angola)|Operation Savannah]]'' halted the advance of South African troops in 1975. The [[Valkiri]] was brought into service in 1977 to counter the Grad.

Adaptations of the launcher were/are produced by several countries including [[China]], [[Czechoslovakia]], [[Egypt]], [[Iran]], [[North Korea]], [[Poland]] and [[Romania]].

=== Belarus ===
[[File:BelGrad BM-21A.JPG|right|thumb|A Belarusian BM-21A "BelGrad"]]
* '''[[BM-21A BelGrad|BM-21A "BelGrad"]]''': This is a modernized version, based on a [[Minsk Automobile Plant|MAZ]]-631705 6×6 truck with 425&nbsp;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 in 2001.

===China ===
* '''[[Type 81 (rocket launcher)|{{vanchor |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 its upgraded version nowadays known as '''[[Type 81 (rocket launcher)#PHZ81 SPMRL|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 [[Shaanxi Automobile Group|Shaanxi Automobile Works]] [[Yan'an]] SX2150 6x6 truck, which unlike the original Russian version, has a cab protected by blast shields.
* '''[[Type 81 (rocket launcher)#Type 83|{{vanchor |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 {{convert|8700|kg|lb}} and can also be used as part of the mine-laying rocket system Type 84. Currently new rockets with ranges between {{convert|30|and|40|km|mi|abbr=on}} are being developed.{{Citation needed|date=June 2025}}
* '''[[Type 81 (rocket launcher)#Type 89|{{vanchor |Type 89 TSPRL}}]]''': This is basically the 40-round launcher of the BM-21 or Type 81 mounted on a tracked chassis with 520&nbsp;hp diesel engine. The same chassis is also used for the Type 83 152&nbsp;mm self-propelled howitzer (PLZ83), the Type 89 120&nbsp;mm tank destroyer (PTZ89) and several other specialised vehicles. The vehicle has a combat weight of {{convert|29.9|short ton|metric ton|lk=on}} and carries 40 spare rockets. Its current PLA designator is '''[[Type 81 (rocket launcher)#PHZ89 SPMRL|PHZ89]]'''.
* '''[[Type 81 (rocket launcher)#Type 90|{{vanchor |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&nbsp;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 resupply trucks [[XC2200|Tiema XC2200]] with 80 rockets and a battery command post on a DongFeng EQ-245 6×6 truck.
* '''[[Type 81 (rocket launcher)#Type 90A|{{vanchor |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 81 (rocket launcher)#Type 90B|{{vanchor |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]].
* '''[[Type 81 (rocket launcher)#PR50 SPMRL|{{vanchor |PR50 SPMRL}}]]''': Development of Type 90B SPMRL with firepower increased by 25% (50 rounds compared to the original 40 rounds). Incorporate features of [[Weishi Rockets|Weishi series self-propelled multiple rocket launchers (WS SPMRL)]] series so that the operating cost and overall life cycle cost for both when most components of PR50 is interchangeable with that of WS series. Also incorporated is a feature originated in Type 90B, which is the adoption of rockets of different ranges, so PR50 has a wide range of 20&nbsp;km to 40&nbsp;km.
* '''[[Weishi Rockets#WS-6|{{vanchor |WS-6 SPMRL}}]]''': A lightweight and more compact derivative of unguided 122&nbsp;mm PR50 SPMRL for rapid deployment, with number of tubes reduced by 60% to 40 * from the original 100 of PR50 MLS.

* '''[[RM-70 multiple rocket launcher|RM-70]]''' (''122 mm RAKETOMET vz. 70''): In 1972 the [[Czechoslovak Army]] introduced its own version of the BM-21 launch vehicle, 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 8x8 10-ton modified [[Tatra 813]] 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. Those rockets can be automatically reloaded into launcher at the same time.

* '''RM 70 Vampire''': RM 70 modern version on [[Tatra 817]] 8x8 chassis with digital fire control system, introduced in 2015.
* '''BM-21 MT STRIGA''': BM-21 launch vehicle on [[Tatra 817]] 4x4 chassis with digital fire control system, without spare rack for immediate reload, introduced in 2022.

=== Egypt ===
The Egyptians domestically manufacture the rockets '''Sakr-18''' and '''Sakr-36''', with a respective range of {{convert|18|km|mi|abbr=on}} and {{convert|36|km|mi|abbr=on}}, and the latest '''Sakr-45''' with a superior range of {{convert|45|km|mi|abbr=on}}. Rather than a standard HE-Frag round, the Egyptian military prefers a {{convert|23|kg|lb|adj=on}} 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. Also the [[RAAD 200]] which is a BM-21 on a new tracked vehicle.

=== 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.

* '''[[RS-122]] Magaria''': In March 2012, the Republic of Georgia unveiled its own heavily modified self-propelled version of the BM-21 Grad. There are innovative improvements similar to that of its Polish counterpart. The crew cabin is armoured and well-protected in accordance with [[Standardization Agreement|STANAG]] level 2 or higher. The 40-tube launcher is fitted with a pinpoint targeting system and has a maximum firing distance of 45&nbsp;km depending on ammunition, guaranteeing much more precision at greater distances. There is enough room for an additional 40-tube pack. The launcher can be deployed and activated directly from inside the crew cab, greatly decreasing time between salvos. However, the traditional external setup is also available. An entire barrage can be fired in less than 20 seconds. The general purpose platform can also be used for more sophisticated rocket systems.<ref>[http://delta.gov.ge/en/product/rs-122/ Multiple Rocket Launcher System – RS-122] {{Webarchive|url=https://web.archive.org/web/20150629002005/http://delta.gov.ge/en/product/rs-122/ |date=29 June 2015 }}.

===Italy===
Produced a limited number of [[Firos (artillery)|FIROS]] 25 and 30 rocket launchers. They had the same configuration, exactly 40 rockets 122&nbsp;mm caliber, compatible also with BM-21 launcher. Range about 25–32&nbsp;km, sold to Libya, United Arab Emirates and probably other customers. About 150 produced in '80s-'90s.

=== North Korea ===
* '''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 an unlicensed copy of the Japanese-manufactured [[Isuzu]] HTS12G 2.5 ton truck chassis.
* '''MRL 122&nbsp;mm M1977''': U.S. DIA code for a system that appears to be a direct copy of the BM-21 "Grad".
* '''MRL 122&nbsp;mm M1985''': This is a more modern version, based on an Isuzu 6×6 truck and probably with a 40-round reload pack mounted between the cab and the launcher.

=== Pakistan ===
Pakistan first obtained these MRLS from China in few numbers (52+ Chinese Type-83) and then reverse engineered to develop these multiple rockets indigenously by KRL (Khan Research laboratories). The new missile system were developed with 16 modernization by Pakistani Engineers. A vertical stabilizer was added to the launcher that improved its accuracy. The new indigenously reverse engineered system were named ''KRL Ghadab''. The range of the indigenously developed rockets were increased to 45&nbsp;km with <1% CEP.
