Increasing the firing distance resulted in unacceptable dispersion of missiles. However, the domestic Smerch, due to the unique design of the rocket, has an accuracy of up to 300 meters. For a system that is able to cover with heavy fire, the area around 700 square. meters, it is insignificant.
Warhead 300-mm projectile "Tornado" can be a single-block high-explosive, cluster (fragmentation type containing self-aiming ammunition or anti-tank mines), thermobaric, etc. Experts in the military field believe that the six Smerch volley fire can stop an offensive of a motorized rifle division.
