Warhead

A warhead is an explosive device used in military conflicts, used to destroy enemy vehicles or buildings.

Typically, a warhead is delivered by a missle, rocket, or torpedo. It consists of the explosive material, and a detonator.

The types of warhead are:

• Explosive - An explosive charge is used to disintegrate the target, and damage surrounding areas with a shockwave.

• Chemical - A toxic chemical, such as nerve gas is dispersed, which is designed to injure or kill human beings.

• Biological - An infectious agent, such as Anthrax is dispersed, which is designed to sicken and kill humans.

The types of explosive are:

• Chemical - Chemicals such as gunpowder store significant energy within their molecular bonds. This energy can be released quickly by a trigger, such as an electric spark.

• Nuclear - An atomic bomb or a hydrogen bomb.

Often, a biological or chemical warhead will use an explosive charge for rapid dispersal.

The types of detonators are:

• Contact - When the warhead makes physical contact with the target, the explosive is detonated.

• Proximity - Using radio waves, or Radar, the warhead is detonated when the target is withing a specified distance. Nuclear explosives often use proximity detonators.
