Rockville Air Force Station (1951-1966) - A Cold War U.S. Air Force Radar Station established during the Korean War. Located near Rockville in Parke County, Indiana. Initially assigned a Permanent ID of P-53 and later a Sage ID of Z-53. Closed in 1966. HistoryEstablished on 16 Apr 1951 and became operational in May 1952 as Rockville Air Force Station manned by the 782nd Aircraft Control & Warning (AC&W) Squadron. According to "Searching the Skies" below, the initial equipment included two FPS-10 radars, one perhaps serving as a height-finder and the other serving as a search radar. The available aerial photographs of the site taken in 1953 and 1954 do not appear to show the second FPS-10, at least not mounted on a tower or visibly mounted in a mobile configuration
The two FPS-10 radars were replaced by 1959 with two FPS-6 height-finders and a FPS-7B search set. This configuration (a SAGE qualified long-range search radar and two SAGE qualified height finders) met the requirements for transition to SAGE System operation.
SAGE System TransitionThe transition of the manual GCI system to the automated SAGE system began with the installation of the FST-2 coordinate data transmitter and search radar upgrades. The FST-2 equipment digitized the radar returns and transmitted the digital returns to the SAGE direction center. Under the SAGE System, interceptor aircraft were directed to their targets by the direction center computers and controllers, greatly reducing the need for local controllers and equipment at every radar station. The FST-2 was a very large digital system using vacuum tube technology. Over 6900 vacuum tubes were used in each FST-2 requiring 21 air-conditioned cabinets, 40 tons of air conditioning, 43.5 kva of prime power, and usually a large new addition to the operations building. The FST-2B modification added two more cabinets but with newer solid-state (transistor) technology to process coded responses from aircraft transponders. SAGE System Operation
The site began operation as a SAGE site in 1959 initially feeding the Truax SAGE Direction Center DC-07 on 1 Jun 1959. On 1 Nov 1959, the squadron designation was changed from the 782nd AC&W Squadron to 782nd Radar Squadron (SAGE) indicating the new SAGE System role. ClosureThe public announcement of the planned closure of Rockville AFS was made by the Secretary of Defense Robert S. McNamara on 19 Nov 1964 through the Pentagon. The projected closure date was by July 19666. Rockville AFS and the 782nd Radar Squadron (SAGE) were deactivated on 25 Jun 1966.
Current StatusAfter serval proposed uses for the facilities the property was sold to the state of Indiana on 13 Dec 1967 for use as the Rockville Correctional Facility. Some of the former Air Force buildings are still in use although many have been demolished.
