Hanna City Air Force Station (ADC ID: P-63, NORAD ID: Z-63) is a closedUnited States Air Force General Surveillance Radar station. It is located 1.6 miles (2.6 km) west-northwest ofHanna City, Illinois. It was closed in 1968. It is still in use by theFederal Aviation Administration as aJoint Surveillance System radar station.
Hanna City Air Force Station (AFS) was one of twenty-eight stations built as part of the second segment of theAir Defense Command permanent radar network. Prompted by the start of theKorean War, on 11 July 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 21 July, the Air Force directed the Corps of Engineers to proceed with construction. 42.8 acres (17.3 ha) were acquired between 1952 and July 1959. The Air Force constructed and operated the station, which included over 35 buildings and miscellaneous smaller structures.
The 791st Aircraft Control and Warning Squadron was activated at Hanna City AFS on 10 May 1951 and began operations usingAN/FPS-3 andAN/FPS-4 radars, and initially the station functioned as aGround-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 1958 Hanna City AFS replaced the AN/FPS-3 with anAN/FPS-20 search radar, and added anAN/FPS-6A height-finder radar. During 1959 the AN/FPS-4 was replaced by a second height-finder radar (AN/FPS-6B), and Hanna City AFS joined theSemi Automatic Ground Environment (SAGE) system, feeding data to DC-07 atTruax Field, Wisconsin. After joining, the squadron was redesignated as the 791st 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. On 31 July 1963, the site was redesignated as NORAD ID Z-85.
In 1964 the AN/FPS-20A was upgraded and redesignated as anAN/FPS-67, and anAN/FPS-90 replaced the AN/FPS-6B height-finder radar. The AN/FPS-67 was upgraded to anAN/FPS-67B in 1968. The AN/FPS-6A was removed some time in this time frame.
The 791st Radar Squadron was inactivated on 18 June 1968, and the site was closed on 30 June due to budget reductions. The radar towers and four buildings were transferred to theFAA and site remains an activeJSS radar site.
The remainder of the site was then declared excess to theGeneral Services Administration on 28 January 1969 and conveyed to theDepartment of Health, Education and Welfare (HEW) on 8 August 1969. It operated asHanna City Work Camp, anIllinois Department of Corrections minimum security prison. The old USAF buildings were still in use up to 2002 and structures used as observation towers appeared to be the old four-legged steel temperate radar towers.
The Hanna City Work Camp closed in October 2002 and the state of Illinois turned over the work camp site to Peoria County in 2009. As of August 2009, the site was occasionally being used for training of Peoria County Sheriff's Office for Special Weapons and Tactics (SWAT).[1] As of 2012, the FAA radar was still at the site and Peoria County was looking for ideas for usage of the remainder of the property, including creation of anagribusiness incubator or community organic farm.[2]
