The R-1 rocket (NATO reporting name SS-1 Scunner, Soviet code name SA11, GRAU index 8A11) was a tactical ballistic missile, the first manufactured in the Soviet Union, and closely based on the German V-2 rocket.^[2] The R-1 missile system entered into service in the Soviet Army on 28 November 1950. Deployed largely against NATO, it was never an effective strategic weapon. Nevertheless, production and launching of the R-1 gave the Soviets valuable experience which later enabled the USSR to construct its own much more capable rockets.
