A nuclear warhead is different than nuclear weapon. A nuclear warhead specifically refers to the toxic materials or the explosive that comes from a missile, torpedo or rocket while a nuclear weapon refers to the main explosive device that causes nuclear reactions. A warhead can either be explosive, chemical and biological.
Explosive warhead can damage the surrounding areas with a blast and completely disintegrate the main target, the chemical warhead is used to kill human beings through a toxic chemical such as nerve gas or poison gas, and a biological warhead is a type of infectious agent that can either make people sick or ultimately kill them. The nuclear warhead is the bullet-shaped canister found on a missile, torpedo or a rocket.
