Terminal High Altitude Area Defense (THAAD)

Customer

Missile Defense Agency (MDA)

Terminal High Altitude Area Defense (THAAD) is a transportable system that intercepts ballistic missiles inside or outside the atmosphere during their final, or terminal, phase of flight. THAAD uses a one-stage hit-to-kill interceptor to destroy incoming ballistic missile targets. THAAD is able to intercept incoming missiles both inside and just outside of the Earth’s atmosphere at a range of 200 kilometers, which mitigates the effects of weapons of mass destruction before they reach the ground. The ability to intercept both inside and outside the atmosphere makes THAAD an important part of layered missile defense concepts, as it falls between the exclusively exo-atmospheric Aegis interceptors and the exclusively endo-atmospheric Patriot interceptors.

There are four main components to THAAD: the launcher, interceptors, radar, and fire control. The launcher is mounted on a truck for mobility and storability. There are eight interceptors per launcher. Current Army configurations of THAAD batteries include six launchers and 48 interceptors. The THAAD system utilizes the Army Navy / Transportable Radar Surveillance (AN/TPY-2) radar to detect and track enemy missiles at a range of up to 1,000 kilometers. The fire control system is the communication and data-management backbone and is equipped with an indigenous THAAD Fire Control and Communications system. The Command, Control, Battle Management, and Communications (C2BMC) also provides tracking and cueing information for THAAD from other regional sensors on Aegis and Patriot systems.
