AnAir Defense Direction Center[2]: 11 (ADDC) was a type of United States command post for assessing Cold War radar tracks, assigning height requests to available height-finder radars, and for "Weapons Direction": coordinating command guidance of aircraft from more than 1 site for ground-controlled interception ("weapons assignment").[3] As with the World War II Aircraft Warning Service CONUS defense network, a "manual air defense system"[4] was used through the 1950s (e.g., NORAD/ADC used a "Plexiglass [sic] plotting board" at the Ent command center.)[5]: 151 Along with 182 radar stations at "the end of 1957, ADC operated … 17 control centers",[5]: 223 and the Ground Observation Corps was TBD on TBD. With the formation of NORAD, several types of ADDCs were planned by Air Defense Command:
Most ADDCs were replaced by Regional Operations Control Centers of the Joint Surveillance System (FOC on December 23, 1980).[7]
