The legendary Katyusha (Russian: Катю́ша) is a type of most known rocket artillery first built and fielded by the Soviet Union in World War II. The Katyushas of World War II, the first self-propelled artillery mass-produced by the Soviet Union, were usually mounted on ordinary trucks. This mobility gave the Katyusha, and other self-propelled artillery advantage: being able to deliver a large blow all at once, and then move before being located and attacked with counter-battery fire.
The weapon is less accurate than conventional artillery guns, but is extremely effective in saturation bombardment. A battery of four BM-13 launchers could fire a salvo in 7–10 seconds that delivered 4.35 tons of high explosives over a 400,000-square-metre (4,300,000 sq ft) impact zone, making its power roughly equivalent to that of 72 conventional artillery guns.
Katyusha batteries were often massed in very large numbers to create a shock effect on enemy forces.
On July 14, 1941, an experimental artillery battery of seven launchers was first used in battle at Rudnya, Smolensk Oblast under the command of Captain Ivan Flyorov, destroying a concentration of German troops with tanks, armored vehicles and trucks in the marketplace, causing massive German Army casualties and panicked retreat from the town.

During deployment in World War II, the Katyusha became a legend and a symbol of the Soviet Army alongside the T-34 tank.

There was approx 10 000 of the Katyushas manufactured during the WW2.

This Katyusha is mounted on ZiS-6 cargo truck chassis.
