The Martin AN/FSG-1 Antiaircraft Defense System, better known as Missile Master, was an electronic fire distribution center for United States Army surface-to-air missiles. It aimed to computerize Cold War air defense (AD) command posts from manual plotting board operations to automated command and control.
The 10 C3 systems used radar netting ("electronic umbrella") at Missile Master military installations for coordinating ground-controlled interception by Nike and MIM-23 Hawk missiles. The vacuum tube fire control logic reduced the time to designate the appropriate missile battery to launch if an enemy target had intruded into a defense area where an AN/FSG-1 system was deployed.
In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/FSG-1" designation represents the first design of an Army-Navy electronic device for fixed special fire control system. The JETDS system also now is used to name all Department of Defense electronic systems.
