The United States Theater Event System (TES) is a missile-warning system. The TES is composed of three ground elements: the Space-Based Infrared System (SBIRS) Mission Control Station, the JTAGS, and the Tactical Detection and Reporting system. The TES in-theater capability will be enhanced significantly as its hardware and software are upgraded to interface with the future SBIRS High and Space Tracking and Surveillance System satellite constellations.
