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.
Military equipment of Israel The military equipment of Israel includes a wide array of arms, armored vehicles, artillery, missiles, planes, helicopters, and warships. Many of these are purchased overseas and many are indigenous designs. Until the Six-Day War of 1967, the Israel Defense Forces' principal supplier was France; since then, it has been the United States government and defense companies. In the early 21st century, Israeli companies such as Soltam Systems began selling arms to the United States. Much of the military equipment undergoes improvements in Israeli workshops. In addition to weapons purchased overseas and indigenous products, Israel also operates and maintains large stockpiles of Soviet-made equipment captured from Arab armies over the course of the Arab–Israeli Conflict.
