context_page_description: The SAGE radar stations of Air Defense Command were the military installations operated by USAF squadrons using the 1st automated air defense 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 to automate the operator environment and provide radar tracks to sector command posts at SAGE Direction Centers, 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 for ground-controlled interception of enemy aircraft by interceptors such as the F-106 developed to work with the SAGE System.

  LP-xx designates Permanent System stations using older radar equipment instead of radars deployed at "P-xx" stations
  P-xx designates "Priority Permanent System" stations completed by May 1952
  RP-xx designates a replacement of one of the permanent stations
  M-xx designates an initial a station of the 1953-7 semi-mobile radar program
  SM-xx designates a station of the 1954–62 "second phase mobile radar program"
  TM-xx designates a station of the 1957–60 "third phase mobile radar program"
  TT-x designates the Texas Towers, radar tower rigs off the East Coast.
  Z-xx is the NORAD identification code
  Codes for Aerospace Defense Command radar stations outside the United States
  C-xx sites on the Canadian Pinetree Line assigned to ADC
  G-xx sites in Greenland established by Northeast Air Command (NEAC) reassigned to ADC, redesignated as C-xx sites.
  H-xx sites in Iceland established by Military Air Transport Service or NEAC reassigned to ADC.
  N-xx Pinetree Line sites in Canada transferred from NEAC to ADC in 1957, redesignated as C-xx sites.
caption: SAGE radar stations were grouped by Air Defense Sectors (Air Divisions after 1966).  The SAGE System networked the radar stations in over 20 of the sectors using AN/FSQ-7 centrals in Direction Centers.
