The Terminal High Altitude Area Defense missile system is intended to protect against hostile incoming threats such as tactical and theater ballistic missiles. The THAAD system provides the upper tier of a „layered defensive shield” to protect high value strategic or tactical sites. The system is capable of intercepting exo-atmospheric and endo-atmospheric threats. A THAAD battery typically operates nine launcher vehicles, with two mobile tactical operations centers (TOCs) and a ground-based radar (GBR).
