Initially established as Mica Peak Air Force Station operated by US Air Force. The site became an FAA/ADC joint-use site circa 1959, furnishing radar track data to FAA ARTCCs and to USAF Direction Centers. The radar site came under FAA control in 1979.

JSS System

When the FAA took over operation of the site in 1979 the equipment configuration included the FPS-67B search radar and a FPS-116 height-finder. The height-finder was maintained by detachments of US Air Force personnel from OLAA 25th ADS until it was removed in 1988.

In 1982 an ADTAC listing of sites to be brought into the JSS System included Keno FAA Radar Site with an FPS-67B search radar, an FPS-116 height-finder, an FYQ-47 Common Digitizer, and an ATCBI-5 SIF/IFF (Beacon) set.

In 1983 the SAGE System deactivated and the Mica Peak FAA Radar Site joined the JSS System with a JSS ID of J-79 as one of the original members.

By 1990 the site was equipped with an FPS-67B search radar and a CD-2C Common Digitizer. The Mica Peak CD-2C was scheduled to receive an upgrade kit to implement three-level weather data processing in May 1992.

The site was reconfigured circa 1998 with the installation of an ARSR-4 3D (combination search & height-finder) radar. The remaining empty USAF radar towers and buildings were removed leaving only the ARSR-4 tower and FAA support buildings on the site.

The current configuration of the Mica Peak FAA Radar Site includes an ARSR-4 and an ATCBI-6 Beacon set. The radar site data is now available to the USAF/NORAD Battle Control System-Fixed (BCS-F) operations centers (EADS & WADS) as well as the FAA Seattle ARTCC (ZSE) and adjacent ARTCCs. Other federal agencies have access to the data under the Homeland Security umbrella.
