RS-82 (rocket family)

The RS-82 and RS-132, Russian for rocket-powered projectile, were unguided air-launched rockets used by Soviet forces during World War II, with the numbers denoting their diameters of 82 and 132 millimeters. Design work began in the late 1920s at the Gas Dynamics Laboratory under Georgy Langemak, with early testing in 1928 and airborne trials in 1932 aboard a Tupolev I-4, and the RS-82 entered official service in 1937 followed by the RS-132 in 1938. The rockets armed Soviet fighters including the Polikarpov I-15, I-16, and I-153, the Polikarpov R-5 reconnaissance aircraft, and the Ilyushin Il-2, with heavier bombers carrying the RS-132, and roughly 12 million of the two types were used by Soviet forces during the war.
