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.

The United Kingdom is one of the five official nuclear weapon states under the Treaty on the Non-Proliferation of Nuclear Weapons and has an independent nuclear deterrent. The UK has been estimated to have a stockpile of 120 active nuclear warheads and 215 nuclear warheads in total. It had renounced the use of chemical and biological weapons in 1956 and subsequently destroyed its general stocks.
