A warhead is the front section of a missile, rocket, torpedo, or bomb that contains the explosive agent or toxic material that is delivered to the target. Warheads can be classified into different types, including explosive and conventional warheads. Explosive warheads use an explosive charge to disintegrate the target and damage surrounding areas with a blast wave. Conventional warheads store significant energy within their molecular structure, which can be released quickly by a trigger. Warheads can also be classified based on their detonators, which include contact, proximity, remote, timed, altitude, and combined detonators.
