History of Citronelle FAA Radar Site
This site became an FAA radar site in 1982 replacing the Dauphin Island Air Force Station Z-249 that closed on 30 Sep 1980. The ARSR-2 was relocated from JFK airport in New York City to a new site near Citronelle in Mobile County, Alabama.
The site furnished radar track data to the FAA and was tied to USAF Direction Centers. The FAA first operated the ARSR-2 search Radar as FAA Site QRB. The initial ARSR-2 remained in operation until it was modified to become a Common Air Route Surveillance Radar (CARSR) in June 2012. The modification used a 7172 Antenna.
The nationwide replacement program converting FAA legacy radar systems to the CARSR radar configuration was completed by 17 Aug 2015 and Citronelle 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 Citronelle FAA Radar Site is now operating with the CARSR radar.
