Description
The RM-70 is a 122mm MLRS (Multiple launch Rocket System) designed and manufactured by Czech Republic. The vehicle was developed to replace the old RM-51. The vehicle which has the NATO designation of M1972, was first seen in 1972 during a military parade in Czechoslovakia. The RM-70 can be ready to fire in less than 2.5 minutes, and leave its combat position in 3 minutes. This MLRS is always in service with Czech Republic, Angola, Finland, Greece, Poland, Slovakia, Cambodia, Rwanda, Uruguay, Sri Lanka and Zimbabwe. In December 2000 Slovak Ministry of Defense and Dhiel BGT Defence started RM-70 Modular German-Slovak modernization project. RM-70 Modular allows this artillery system to launch both 122mm and 227mm rockets used on the M270 MLRS.

Armament
The RM-70 is armed with a rack of 40 x 122mm rocket tubes fitted to a traversing/elevating platform mounted at the rear of a Tatra 813 8x8 truck chassis. The rocket tube arrangement is a single rectangular bank of four layers each with 10 tubes. The rocket platform can rotate from 125° left to 70° right, with elevation from +55 ° to 0°. Back of the crew cabin, there is a magazine rack with 40 rockets. The main feature of the RM-70 is its rapid reload system. Once all 40 122-mm (4.8 in) fin stabilised rockets have been fired, the launcher barrels can be aligned with a magazine pack of a further 40 rockets that are then mechanically inserted into the empty barrels. The entire reloading process can take less than a minute, far shorter than employing the usual manual reloading methods and enabling the RM-70 to deliver two rapid, destructive salvos, each complete salvo lasting a total of between 18 to 22 seconds. For its self-protection, a 7.62mm machine gun is mounted at the right side top of the crew cabin.
Design and protection
The RM-70 is based on 8x8 truck chassis Tatra. The truck is fitted with an armoured crew cabin at the front of the chassis which provides protection against firing of small arms and shell splinters. The rockets launcher is mounted at the rear of the chassis. Between the armoured crew cab and the launcher, a magazine rack with 40 additional rockets is available. All fire operations are operated from inside of the crew cabin, but the launch can also be operated remotely by one soldier with an electric remote control connected to the vehicle by a cable of a length of 64m.
Rockets
The 122-mm rockets are essentially the same as those fired from the Soviet/Russian BM-21 Grad (Cherrystone) system, with a range of 20,000 m. By updating the rocket motors the latest versions of these rockets can extend the maximum range up to 36,000 m. Warhead can vary from high explosive fragmentation to enhanced warheads with pre-formed fragments. Cargo warheads can also scatter small anti-tank mines.
Mobility
The rocket launcher system of RM-70 is carried on a 8x8 truck chassis Tatra 813. The Tatra 813 truck is motorized with a T-930-3 V-12 air-cooled diesel developing 270 hp. at 2,700 rpm coupled to a dual-range 5-speed plus overdrive gearbox providing 20 forward and 4 reverse gears. The RM-70 can run at a maximum speed of 75 km/h with a maximum cruising range of 1,100 km. The RM-70 can climb a gradient of 60%, a vertical obstacle of 0.6m, cross a trench of 1.6m maximum and fording depth of 1.4m without preparation.
Accessories
The Tatra 813 chassis is fitted with a central tyre-pressure regulation system, which enables the driver to adjust the tyre pressure to suit the type of ground being crossed. A dozer blade is mounted at the front of the truck for preparing fire positions and clearing obstacles. The truck can be also fitted with a 22,000 kg winch. Standard equipment of the RM-70 includes also an NBC protection system.
