781st radar squadron

The 781st Radar Squadron was an Air Defense Command unit of the United States Air Force, activated in 1951 during the early years of the Cold War. Stationed at Fort Knox, Kentucky, it was tasked with operating radar systems as part of the continental air defense network, providing early warning and tracking of potential aerial threats. The squadron played a critical role in monitoring U.S. airspace, integrating with the Semi-Automatic Ground Environment (SAGE) system in the 1960s. The unit was inactivated in 1968 as advancements in technology and changes in defense strategy led to a reorganization of air defense assets.
