Iron Dome is part of what professionals describe as a “multi-layer shield” that includes the Arrow system, which is being upgraded, and the Magic Wand, now in development. When finished, the system should guard against destruction from crude, short-range rockets made in Gaza to ballistic missiles from Iran.
Iron Dome shoots down rockets with a radar-guided missile known as Tamir, which was developed by Rafael Advanced Defense Systems, an Israeli company. The radar was developed by Elta, a subsidiary of Israel Aerospace Industries, and another company, Impress, developed the command and control system.
Because each interceptor missile costs $40,000 to $50,000, the system is designed to aim only at rockets headed for populated areas and to ignore those destined for open ground outside cities and towns.
