The main goal of the upgrade was to streamline the firing, improve accuracy, shorten the preparatory time and leaving the firing position. The main emphasis was laid to automate and simplify operations related to the launch and control of firing, resulting in a fully autonomous system capable of immediate reaction.
TATRA MILITARY CHASSIS

Fitted with the latest electronic components, optional NBC filtration system, optional independent AC unit & heating and optional auxiliary power unit (APHU).
The BM-21 MT is an upgrade project of the original 122 mm BM-21 GRAD rocket launcher. Designed for the carpet destruction of the enemy‘s position, resources, military equipment and human forces within a distance from 2,000 m to 20,000 m. The BM-21 MT is a forty-tube, multi-launch, self-propelled rocket artillery system. BM-21 MT is firing unitary 122 mm JROF high-explosive fragmentation rocket projectiles at large area targets. The rocket launcher can ﬁre both single rounds and volleys from the cabin or using a portable device from a nearby trench (max. distance 60 m). The basic type of the fire is indirect fire. Direct fire with elevation from 0° to 10° can be done within the range determined by elevation and traverse sensors. The original URAL-375D chassis was replaced with the T-815 chassis with air axle suspension.
