A Super Combat Center (SCC) was a planned Cold War command and control facility for ten NORAD regions/Air Divisions in Canada and the United States. For installation in nuclear bunkers, the command posts were to replace the last of the planned Air Defense Command Combat Centers to be built for vacuum tube AN/FSQ-8 Combat Control Centrals. The survivable SCCs were to use solid-state (transistorized) AN/FSQ-32 equipment which was to provide the Semi-Automatic Ground Environment for operators at 10 Air Divisions — 5 of the centers were to also serve as Air Defense Direction Centers ("SCC/DCs") for commanding ground-controlled interception in sectors of the 27th, 30th, 32nd, 33rd, and 35th Air Divisions. ADC's November 1958 plan to complete the hardened SCCs by April 1964 included fielding 3 additional AN/FSQ-32 systems above-ground for the Albuquerque, Miami, and Shreveport sectors.
