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.
Ilyushin Il-2 The Ilyushin Il-2 (Cyrillic: Илью́шин Ил-2) Sturmovik was a ground-attack aircraft (Cyrillic: Штурмови́к, "Šturmovík") produced by the Soviet Union in large numbers during the Second World War. With 36,183 units of the Il-2 produced during the war, and in combination with its successor, the Ilyushin Il-10, a total of 42,330 were built, making it the single most produced military aircraft design in aviation history, as well as one of the most produced piloted aircraft in history along with the American postwar civilian Cessna 172 and the Soviet Union's own then-contemporary Polikarpov Po-2 "Kukuruznik" multipurpose biplane.
