The laser beam system used to shoot down the two missiles during Friday's test is called a Tactical High Energy Laser (THEL). THEL is a short-range, ground-based air-defense system under test and development by TRW Inc. for the U.S. Army and the Israel Ministry of Defense. The device uses a high-energy, chemically-generated laser beam to shoot down rocket attacks. Israel has an urgent need to protect civilians and others living along its northern borders. The THEL laser system is housed in several semitrailer-sized containers. THEL is made up of three systems: a control system, which tracks the incoming missiles while in flight and is used to aim the laser system; a pointer-tracker system that contains the firing system and the laser itself -- a deuterium fluoride chemical laser.
