NAVSPASUR

NAVSPASUR, short for Naval Space Surveillance System, was a United States Navy radar network established during the early 1960s. Its primary mission was to detect and track satellites and other objects in Earth's orbit, providing vital space situational awareness during the Cold War. The system consisted of a series of transmitting and receiving stations spanning the southern United States, forming an electronic "fence" across the continent. Operated for decades by the U.S. Navy, NAVSPASUR was transferred to the United States Air Force in 2004 and later became part of the Air Force Space Surveillance System, continuing its legacy in American space defense.
