Rockville Air Force Station (ADC ID: P-53, NORAD ID: Z-63) is a closed United States Air Force General Surveillance Radar station. It is located 1.7 miles (2.7 km) west-northwest of Rockville, Indiana. It was closed in 1966.

History[edit | edit source]

Rockville Air Force Station was one of twenty-eight stations built as part of the second segment of the Air Defense Command permanent radar network. Prompted by the start of the Korean War, on July 11, 1950, the Secretary of the Air Force asked the Secretary of Defense for approval to expedite construction of the permanent network. Receiving the Defense Secretary's approval on July 21, the Air Force directed the Corps of Engineers to proceed with construction.

Opened in 1951, the 782d Aircraft Control and Warning Squadron was activated on 16 April. It began operating a pair of AN/FPS-10 radars at Rockville in May 1952, and initially the station functioned as a Ground-Control Intercept (GCI) and warning station. As a GCI station, the squadron's role was to guide interceptor aircraft toward unidentified intruders picked up on the unit's radar scopes. In the mid / late 1950s, an AN/CPS-6B search radar was in use, according to one veteran. During 1959 Rockville AFS joined the Semi Automatic Ground Environment (SAGE) system, feeding data to DC-07 at Truax Field, Wisconsin. After joining, the squadron was redesignated as the 782d Radar Squadron (SAGE) on 1 November 1959. The radar squadron provided information 24/7 the SAGE Direction Center where it was analyzed to determine range, direction altitude speed and whether or not aircraft were friendly or hostile. By 1960 the original radars had been phased out and replaced by two AN/FPS-6 height-finder radars and an AN/FPS-7B search radar. On 31 July 1963, the site was redesignated as NORAD ID Z-53.

In addition to the main facility, Rockville operated an AN/FPS-18 Gap Filler site:

Rockville AFS was colosed on 2 June 1966 due to budget reductions. It was sold to the state of Indiana and is now the Rockville Correctional Facility. Many former Air Force buildings are still in use.
