A nuclear weapon is a weapon which derives its destructive force from the nuclear reactions of nuclear fission. Besides fission, a different kind of nuclear reaction called fusion can be used to create an even more powerful explosion. As a result, even a nuclear weapon with a relatively small yield is significantly more powerful than the largest conventional explosives, and a single weapon can be capable of destroying or seriously disabling an entire city.

he second basic type of nuclear weapon produces a large amount of its energy through nuclear fusion reactions, and can be over a hundred times more powerful than fission bombs. These are known as hydrogen bombs, H-bombs, thermonuclear bombs, and fusion bombs. They work by utilizing the Teller-Ulam design, in which a fission bomb is detonated next to fusion fuel. The X-rays of the fission explosion compress and heat a capsule of tritium, deuterium, or lithium, starting a fusion reaction. Each of these components are known as "stages". A final fission stage is often included as well for multi-megaton fusion weapons.
