👉 Defense Missile Defense (DMD) systems, commonly known as "Define Missiles," are a suite of advanced missile defense technologies designed to detect, track, and intercept ballistic missiles during their various phases—from launch to mid-flight and re-entry. These systems utilize a combination of ground-based interceptors, such as the Patriot Advanced Capability-3 (PAC-3) and Terminal High Altitude Area Defense (THAAD), as well as space-based sensors like the Aegis Ashore and the Terminal High Altitude Area Defense (THAAD) satellites, to provide layered defense against potential missile threats. The DMD systems are crucial for protecting national security by reducing the risk of intercontinental ballistic missile (ICBM) attacks and ensuring the safety of populated areas.
