This article is about the NORAD Cold War computer network. FSQ-8 production was halted c. Soviet air attack, operating in this role from the information about automatic machines project pdf 1950s into the 1980s. FSQ-7 which occupied an entire floor, approximately 22,000 square feet not including supporting equipment.
Information was fed to the DC’s from a network of radar stations as well as readiness information from various defence sites. The computers, based on the raw radar data, developed “tracks” for the reported targets, and automatically calculated which defences were within range. SAGE became operational in the late 1950s and early 1960s at a combined cost of billions of dollars. 1980s, by which time the tube-based FSQ-7’s were increasingly costly to maintain and completely outdated. The radars determined the map coordinates of the enemy, but could generally not see the fighters at the same time. This meant the fighters had to be able to determine where to fly to perform an interception but were often unaware of their own exact location and unable to calculate an interception while also flying their aircraft. The sectors used additional systems to track their own aircraft, plotting both on a single large map.
However, the system was also slow, often providing information that was up to five minutes out of date. The system was also extremely expensive in manpower terms, requiring hundreds of telephone operators, plotters, trackers and all of the radar operators on top of that. This was a serious drain on manpower reserves, making it difficult to expand the network. The idea of using a computer to handle the task of taking reports and developing tracks had been explored beginning late in the war. CH stations to automatically convert radar readings into map locations, eliminating two people. X and Y locations from a map and automatically generated tracks from repeated inputs.
However, all of these systems were relatively small in geographic scale, generally tracking within a city-sized area. August 1949, the topic of air defense of the US became important for the first time. A study group, the “Air Defense Systems Engineering Committee” was set up under the direction of Dr. Their December report noted a key problem in air defense using ground-based radars.
A bomber approaching a radar station would detect the signals from the radar long before the reflection off the bomber was strong enough to be detected by the station. The only solution to this problem was to build a huge number of stations with overlapping coverage. At that point the problem became one of managing the information. Manual plotting was immediately ruled out as too slow, and a computerized solution was the only possibility. In order to be able to handle this task, the computer would need to be fed information directly, eliminating any manual translation by phone operators, and it would have to be able to analyze that information and automatically develop tracks. A system tasked with defending cities against the predicted future Soviet bomber fleet would have to be dramatically more powerful that the models used in the NTDS or DATAR. The Committee then had to consider whether or not such a computer was even possible.

Manual plotting was immediately ruled out as too slow, and automatically calculated which defences were within range. 3 subsequent phases of deployments and by June 30, falschgeld: Blüten aus dem Geldautomat?
