How many existing basic design types are there of the weapons the United States and the Soviet Union had an arms race over?
Nuclear arms race The nuclear arms race was a competition for supremacy in nuclear warfare between the United States, the Soviet Union, and their respective allies during the Cold War. During this period, in addition to the American and Soviet nuclear stockpiles, other countries developed nuclear weapons, though none engaged in warhead production on nearly the same scale as the two superpowers.
R-1 (missile) The R-1 rocket (NATO reporting name SS-1 Scunner, Soviet code name SA11, GRAU index 8A11) was a short-range ballistic missile manufactured in the Soviet Union based on the German V-2 rocket. Even though it was a copy, it was manufactured using Soviet industrial plants and gave the Soviets valuable experience which later enabled the USSR to construct its own much more capable rockets.
