SAGE radar stations

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"[1]) for ground-controlled interception of enemy aircraft by interceptors such as the F-106 developed to work with the SAGE System.

Also part of the SAGE Air Defense System were radar stations in sectors with Manual Control Centers which provided radar tracks by voice communication, and fourth floor consoles of SAGE Direction Centers in adjacent sectors could input those stations' tracks in the "Manual Inputs" room adjacent to the "Communication Recording-Monitoring and VHF" room.

Most radar stations were part of the preceding Permanent System and some SAGE stations had Ground Air Transmit Receive (GATR) equipment for radioing command guidance by TDDL automated data link to autopilots of equipped interceptors for vectoring to targets[9] (e.g., GATR site R-28 was at Palermo Z-54.)

A few Permanent System stations continued operations without being redesignated with Z-xx "NORAD identification codes", e.g., 1952 Duncanville P-79 until 1964, 1958 Cottonwood SM-150 until 1965, and 1948 Hamilton P-48 until 1973.

The joint-use site system (JUSS)[18] was completed after the 1959 Missile Master Plan resolved the surface-to-air missile (SAM) dispute:[19] both the US Army and USAF SAMs would be deployed and their computers were integrated with each CCCS netting the USAF sector or Army region radar stations.

The SAGE System used crosstelling of "SAGE reference track data" from the BOMARC AN/FSQ-7 to the NIKE Hercules AN/FSG-1's "two surveillance and entry consoles",[20] and the nine bunker sites had been selected by June 1957 for coordinating Army batteries' intercept of targets within an interior NIKE Defense Area of the USAF sector.

Construction of the Highlands Army Air Defense Site for NY-55DC (fourth AN/FSQ-7) began adjacent to the 1948 Highlands P-9 to use the existing equipment as "Missile Master organic radars"[20] and in 1961, the 770th Radar Squadron at Palermo LP-54 moved to the existing Ft Meade Nike AADCP (W-13DC with USAF RP-54 designation).

Many of the SAGE radar stations, particularly the locations with Air Route Surveillance Radars (e.g., San Pedro Hill Z-39) were retained when the SAGE System was replaced by the Joint Surveillance System for which the USAF declared full operational capability of the first seven Regional Operational Control Centers (ROCCs) on December 23, 1980[26] (the NORAD Command Center was also upgraded).

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.
