SAGE radar stations: The SAGE radar stations of Air Defense Command (Aerospace Defense Command after 1968) were the military installations operated by USAF squadrons using the 1st automated air defense environment (Semi-Automatic Ground Environment) and networked by the SAGE System, a computer network.  Most of the radar stations used the Burroughs AN/FST-2 Coordinate Data Transmitting Set (CDTS) to automate the operator environment and provide radar tracks to sector command posts at SAGE Direction Centers (DCs), e.g., the Malmstrom Z-124 radar station was co-located with DC-20.  The sector/division radar stations were networked by DCs and Manual Control Centers to provide command, control, and coordination (e.g., at Topsham AFS for the "Bangor North American Air Defense Sector") for ground-controlled interception of enemy aircraft by interceptors such as the F-106 developed to work with the SAGE System.
