Raytheon Company and Aerojet, a GenCorp company, completed a kinetic warhead system integration test for Standard Missile-3 Block IB. The test verified the ability of the warhead to detect, track and intercept a moving ballistic missile target in a zero-gravity environment. During the test, a fully operational, flight-weight kinetic warhead operated on an air-bearing test stand and performed in a high-altitude chamber at Aerojet’s Sacramento, Calif., facility. The kinetic warhead’s seeker tracked a simulated target while the guidance computer sent information to the new Throttleable Divert and Attitude Control System. Once the TDACS received the information, the system fired its...
