Abstract
Abstract An air defense missile weapon system in which a plurality of unmanned missiles penetrate, survey, identify, attack and destroy target areas that include air defense sites and sites of military interest. Each of the missiles has an airframe, sensors, data links, propulsion means, and a plurality of control surfaces. The missiles are launched from a carrier aircraft towards the target sites from a stand-off range. The missiles preferably operate in cooperative teams of hunter and killer missiles, and are interoperable with a plurality of military aircraft and other existing weapon systems.
