PST-72018 1/72 M-13 Katyusha Soviet WW2 MLRS mod. 1941 (ZiS-6) model kitOriginally, the M-13 Katyusha rocket launcher was mounted on the chassis of a ZIS-5 truck. Experience with this was unsatisfying on thus ZIS-6 chassis were chosen instead. Later, the M-13 was mounted on all kinds of American truck chassis, and in the end on Studebaker chassis only. Most of the Katyusha launchers used in WWII were based on this American truck.
The ZIS-6 truck was nothing more than a ZIS-5 with dual rear axles. Very few were produced and most of them ended up as civilian cargo trucks, some as fire staircase carriers for use with the fire brigade.
In 1941, the Germans soon came to know the terrifying weapon which was the M-13. This rocket launcher was able to launch 16 20mm rockets over a distance of 9 kilometers. Each rockets was able to tear apart armoured vehicles and decimated large groups of infantry within moments. The Germans soon nicknamed the weapon "Stalin's organ" as per the shrieking sound the rockets made. The Russians had nicknamed the weapon "Katyusha" (Cathy or Catherine), inspired by a very popular song from those days.
