When it is established that defensive action is to be taken, the operator can call up weapons status information, which is being continually updated via card reader inputs. He can then call upon the computer for solutions to possible intercepts, the solutions being made to appear at the requesting display console. Once a weapon is assigned, the computer generates the necessary launch and guidance commands, and the track on the weapon is initiated automatically. The launch and guidance commands, stored momentarily in core memory, are accepted by the message processor, formatted, and transmitted over the appropriate communication lines. All the while, messages are being exchanged as required with adjacent air defense sectors.
Peripheral equipment performs support functions.
Magnetic tape units are used for simulation inputs and recording for training, and backup storage for programs. A typewriter is a backup input for the card reader and is also used in system maintenance. It also houses the central power control to assure orderly system shutdown without loss of stored data in the event of a power failure. A line printer provides high-speed printout to permit rapid program evaluation and change, and evaluation of test missions. Simulator message composers are training aids for weapons director, for both initial training and maintenance proficiency.
