Thomasville Air Force Station came into existence as part of Phase III of the Air Defense Command Mobile Radar program. On October 20, 1953 ADC requested a third phase of twenty-five radar sites be constructed. The 698th Radar Squadron was inactivated on 30 September 1969 and Thomasville AFS was closed due to a draw-down of ADC and budget constraints. After its closure, the site was the location of the Thomasville Mental Health & Rehabilitation Center, and Alabama Department of Youth Services. However, the former closed completely by November 2003.
