Stalin's organ - BM 13

German troops coined the sobriquet Stalin's organ (German: Stalinorgel), for its visual resemblance to a church musical organ and alluding to the sound of the weapon's rockets.The distinctive howling sound of the rocket launching terrified the German troops and could be used for psychological warfare. The rocket's devastating destruction also helped to lower the morale of the German army.An officer who appears briefly on the recording is Soviet marshal Ivan Stepanovich Konev ,also served in Imperial Russian Army. Salvo of BM13 regiment was taking about 5-10 sec.Total number of launched rounds was 576.Area of coverage more than 100 hectares.Fragmentations of exploded rounds were heating up to 800 degrees Celsius and thus they were setting on fire everything around them.Advantage of BM-13 was that units with BM-13 were quickly changing their location after salvo.
