An IFICS site should not require permanent onsite support personnel. Personnel would only be required when the IFICS needs maintenance. The IFICS is a transmitter that would transmit when a GBI would be launched to intercept an incoming ballistic missile. The IFICS would consist of a transmitter/receiver enclosed in a 5.8-meter (19 foot) diameter inflatable radome adjacent to support structures. The entire facility would require an area of 0.4 hectare (1 acre) including the perimeter fence.The IFICS would not generate any electromagnetic radiation (EMR) except when a GBI would be launched in defense of the United States and during annual system test/training, which does not involve missile firing. During this time, the short pulses of the IFICS would not present any EMR hazards outside the fenced perimeter boundary. The only air and noise emissions would be associated with the electrical generators required to provide power to the site. These generators would only be required as backup power sources if commercial power to the site failed, or if required to support a mission. At sites where no commercial power is available, or where the reliability of commercial power does not meet NMD system requirements, the generators would operate continuously.
Sites that are not located on existing military installations will be accessed from existing roads by a gated access drive. An area of approximately 0.4 hectare (1 acre) will be secured with a 1.8-meter (6-foot) high perimeter fence surrounding the IFICS support structure, equipment shelter, power generator, and fuel storage area.
