An artist's concept of the Army Homing Overlay Experiment (HOE) homing and kill vehicle preparing to intercept a mock nuclear warhead more than 100 miles above the mid-Pacific Ocean. The HOE sensor in nose locks onto the target and the third stage axial propulsion motor maneuvers the vehicle onto a collision course. The 15-foot radial "net" opens to destroy the incoming warhead by impact at more than 15,000 feet per second
