The Stilleto is a weapon featured in Clarkes science fiction novel Earthlight. In the 1955 Clarke novel, the weapon is said to emit a beam of light that was able to pierce a spacecraft. The writer afterwards explains that the weapon he mentioned in his novel was actually a stream of liquefied metal that gets shot through space with very high speed and force.
The research and development arm of the Department of Defense (Defense Advanced Research Project Agency or DARPA) is developing a weapon called MAHEM. This is patterned after Clarkes fictional weapon.
MAHEM stands for Magneto Hydrodynamic Explosive Munition. The weapon will be using magnetism to propel either liquid or solid metal. It will be similar to other currently existing weapons since it will use explosions and electromagnetism to power the release of the metal. Weapons that use the same kind of power are called High-Explosive Anti Tank (HEAT). One example of a HEAT weapon is a bazooka.
DARPA is currently developing MAHEM as something that can be attached to a warhead. Once the missile is near the target, it will release MAHEM and be able to stop tanks and other large moving vehicles at close...
