Strategic Military Panel of the
President's Science Advisory Committee

The area defense component of the system could provide a very effective defense against the initial Chinese ICBM capability which probably would not be equipped with adequate penetration aids. It is designed to acquire targets at 1600 n. m. and to launch interceptors when the target is 1000 n. m. away so that interception takes place at ranges up to about 300 n. m. from the defensive missile launching sites and at altitudes of 300,000 feet or higher.
