Blast: A strong shock wave is provided by the detonation of the explosive.
Fragmentation: Metal fragments are projected at high velocity to cause damage or injury.
Continuous rod: Metal bars welded on their ends form a compact cylinder of interconnected rods, which is violently expanded into a contiguous zig-zag-shaped ring by an explosive detonation. The rapidly expanding ring produces a planar cutting effect that is devastating against military aircraft, which may be designed to be resistant to shrapnel.
Shaped charge: The effect of the explosive charge is focused onto a specially shaped metal liner to project a hypervelocity jet of metal, to perforate heavy armour.
Explosively formed penetrator: Instead of turning a thin metal liner into a focused jet, the detonation wave is directed against a concave metal plate at the front of the warhead, propelling it at high velocity while simultaneously deforming it into a projectile.
Using radar, sound waves, a magnetic sensor, or a laser the warhead is detonated when the target is within a specified distance. It is often coupled with directional explosion control system that ensures that the explosion sends the fragmentation primarily towards the target that triggered it.
remotely detonated via signal from operator (Not normally used for warheads except for self-destruction)
Warhead is detonated after a specific amount of time.
