The function of ground-based midcourse defense (GMD) systems is to provide combatants the ability to seek and destroy intermediate- and long-range ballistic missiles en route to the US homeland. Data are transmitted from the defense satellite communication system, and compiles an image using the coordinated information. The system is able to relay real-time data once missiles have been launched. The GMD can also work to receive information from the C2BMC, which allows Aegis SPY-1, and TPY-2 to contribute to the defense system.
