BM-21 MU

FULFILLING NATO STANAG REQUIREMENTS

The life cycle of the equipment is at the same level as in the original BM-21. All electronic parts has resistance -20°C to +55°C and humidity 95%.

ORIGINAL BM-21 DIFFERENCES

Old system allowed firing only from prepared combat position. Procedure of preparing that position, reaching it, getting into fire direction and leaving combat position was quite timeconsuming. Goal of a new system is fully automatic mode of aiming and firing, which reduce time needed for assuming combat position and increase fire effectivity and accuracy in the target area.

FIREPOWER & FIRE CONTROL SYSTEM

Extensive area impacted by a volley of rockets. Area of effect is 3,000 m2 for single round and up to 30,000 m2 for volley of 40 rockets. Fire control system (FCS) with ballistic computer is optionally completed with inertial navigation and advanced command & communication equipment.

EQUIPMENT

Fitted with the latest electronic components, optional NBC filtration system, optional independent AC unit & heating and optional auxiliary power unit (APHU).

The BM-21 MU is a mobile platform for the 40-round high explosive fragmentation artillery system providing concentrated fire support to the troops over large target areas covering ranges depending on the type of used shell. It is an upgraded variant of the Russian BM-21 Multiple Rocket Launcher. The rocket launcher can fire both single rounds and volleys from the cab or via remote control device from a nearby trench. Modernization preserves tactical and technical features of BM-21 chassis. The principal mode of fire is indirect fire, direct fire can be performed only within the range determined by traverse and elevation sensors.
