Description

The BM-21 Grad is a Soviet truck-mounted 122-mm multiple rocket launcher, developed in the early 1960s. The development of the 122 mm BM-21 Grad divisional-level RSZO took place in the mid-1950s under the guidance of the Splav Scientific Production Concern at Tula. The BM-21 122 mm multiple rocket launcher (MRL) system entered service with the Soviet Army in 1963 to replace the aging 140 mm BM-14 system. The main role of the BM-21 Grad system is to support the division with suppressive fire to counter anti-tank missile, artillery and mortar positions, destroy strong points and eliminate enemy nodes of resistance on the immediate battlefield.

Variants:

- BM-21 "Grad": Original 40-round launcher, mounted on a Ural-375D truck.
- BM-21-1: Some systems use the Ural-43201 5t truck chassis with KamAZ-740 diesel engine of 210 hp.
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. 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. He 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 inex of 9P125.
- 9A51 "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.
- 9K132 "Grad-P": Single-round man-portable launcher, which can be reloaded and used again. The rocket itself is a 122mm fin-stabilized rocket, armed with any of the warheads used on BM-21 rockets. The weapon is not often used by the Russian military, but is popular with paramilitary and guerrilla forces.
- BM-21PD "Damba" (Protivodiversionnyi): 40-round launcher mounted on Ural-375D or 43201 truck. 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.


Technical Data

Armament
The BM-21 GRAD is equipped with a bank of 40 launch tubes 122 mm arranged in a rectangular shape that can be turned away from the unprotected cab. The rocket tube arrangement is a single rectangular bank of four layers each with 10 tubes.
Rockets
The rockets can be either fired singly or in a salvo lasting six seconds. Manual reloading by the two-man crew takes approximately five minutes. The launcher can traverse a full 360º. The system is limited to firing HE fragmentation-type rockets only. The BM-21 can launch rockets directly from the cab or remotely from outside of the truck cab with a 64-meter cable. Standard rockets has a maximum firing range of 20 km, but with the use of latest generation of rockets the range can be increased up to 35/40 km.
Various 122mm rockets have been developed for the BM-21 Grad MRLS:
- 9M22U HE fragmentation rocket
- 9M521 HE fragmentation rocket with enhanced power warhead. In engaging targets, twice effective as 9M22U
- 9M522 HE fragmentation rocket with separable warhead. In engaging targets, six effective as 9M22U
- 9M217 rocket with sensor-fuzed submunitions.
- 9M218 rocket with HEAT fragmentation submunitions.
Design and protection
The cabin truck of BM-21 GRAD is not protected. The launch vehicle's cabin accommodates the launch preparation and firing equipment. Individual round, selective ripple or salvo firing is possible from either the cab or from a remote-control unit connected to the vehicle via a 64 m cable. The BM_21 has a crew of six including two soldiers in the 9F37 ammunition resupply vehicle.
Mobility
The BM-21 consists of a Ural-375D six-by-six truck chassis. The truck Ura-375D is powered by a water-cooled V-8 180 hp gasoline engine ZIL-375. The BM-21 has a maximum road speed of 80 km/h, road range of up to 800 kilometers, and can cross fords up to 1.5 m deep.
Accessories
The truck of the BM-21 has a collapsible canvas cab, removable doors and windscreen, telescopic steering wheel and tie-down points for aiding parachute dropping and landing. A PG-1M panoramic telescope with K-1 collimator can be used for sighting. A spare tire is fitted at the rear of the crew cab.
