Definition
A nuclear warhead is the explosive payload of a missile, rocket, or torpedo that uses a nuclear reaction to create a massive explosion. π₯ It can be a fission (atomic) bomb or a fusion (hydrogen) bomb, or a combination. These weapons unleash tremendous energy, causing widespread devastation through blast, heat, and radiation. They are part of a country's nuclear arsenal, intended as a deterrent, or a tool of aggression. The risk of nuclear warheads being used is an ongoing global concern.
