متى قامت روسيا بإنتاج أول جيل من سلاح الكاتيوشا؟
In June 1938, the Soviet Reaction-Engine Scientific Research Institute (RNII) in Moscow was authorized by the Main Artillery Directorate (GAU) to develop a multiple rocket launcher for the RS-132 aircraft rocket (RS for , 'rocket-powered shell'). I. Gvay led a design team in Chelyabinsk, Russia, which built several prototype launchers firing the modified 132 mm M-132 rockets over the sides of ZiS-5 trucks. These proved unstable, and V.N. Galkovskiy proposed mounting the launch rails longitudinally. In August 1939, the result was the BM-13 (BM stands for "боевая машина" (translit. "boyevaya mashina"), 'combat vehicle' for M-13 rockets).
