Cedar City FAA Radar Site (1962-Active) - A Federal Aviation Administration (FAA) Long Range Radar (LLR) site first established in 1962 on Blowhard Mountain above Cedar City, Iron County, Utah. The site is used to identify and track military and civilian aircraft movements within a 200-mile radius and to provide air-ground radio communication with those aircraft. Assigned a SAGE System ID of Z-216 and an FAA ID of CDC. Active FAA Radar Site.

This site was constructed in 1961 and became an operational FAA radar site in 1962, furnishing radar track data to the FAA Salt Lake City ARTCC and to USAF SAGE System Direction Centers. In 1964 a microwave communications link was established to also furnish radar data to the Los Angeles ARTCC at Palmdale, California. By the 1980s the site required a six-man maintenance crew to provide 24/7 coverage.

The initial FAA ARSR-2 search radar remained in operation until it was modified to become a Common Air Route Surveillance Radar (CARSR) reportedly by 25 May 2011.

A FYQ-47 Common Digitizer was probably placed in service by February 1973 when the USAF/FAA FST-2 to FYQ-47 replacement program was completed.

The nationwide replacement program converting FAA legacy radar systems to the CARSR radar configuration was completed by 17 Aug 2015 and Cedar City FAA Radar Site was a part of that program. Legacy FAA radars underwent a Service Life Extension Program (SLEP) that replaced key components in the vintage ARSR-1, ARSR-2, FPS-20, FPS-66 and FPS-67 radars. The CARSR program replaced legacy klystron radar transmitters with a solid-state transmitter as well as renovating the radar receiver and signal processor. The CARSR also replaces the CD-2 data processor. The Cedar City FAA Radar Site is now operating with the CARSR radar.

The radar site data is available to the USAF/NORAD Battle Control System-Fixed (BCS-F) operations centers (EADS & WADS) as well as the FAA Salt Lake City ARTCC, the Los Angeles ARTCC and adjacent ARTCCs.
