Definitions for "National missile defense"
A ground-based anti-ballistic missile system designed to protect a country against ballistic missile threats. The proposed U.S. system consists of four elements: ground-based interceptors (GBI); a ground-based radar (GBR); a battle management command, control, and communications (BM/C 3) system; and a constellation of Space and Missile Tracking System (SMTS) satellites. The term was used by the Clinton Administration to differentiate systems able to intercept long-range missiles from systems able to intercept only short-range, or "theater"-range missiles. The Bush Administration integrated TMD and NMD into a layered BMD system.
