Omaha Air Force Station (ADC ID: P-71, NORAD ID: Z-71) is a closed United States Air Force General Surveillance Radar station. It is located 7.5 miles (12.1 km) north of Omaha, Nebraska. It was closed in 1968.


Omaha 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.

The 789th Aircraft Control and Warning Squadron was activated at the station on 1 May 1951. The squadron activated an AN/CPS-4 and AN/FPS-3 radar at Omaha in April 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. Eventually the Air Force replaced the height-finder radar with an AN/FPS-6, and replaced the AN/FPS-3 search radar with an AN/FPS-20. In late 1959 this station was also performing air traffic control duties for the FAA.

An Army Air-Defense Command Post (AADCP) was established at Omaha AFS in 1959 for Nike missile command-and-control functions as part of the Offutt AFB Defense Area. The site was equipped with the AN/GSG-5(V) BIRDIE solid-state computer system. The Army Nike radars were fully integrated with the Air Force sets. Semi Automatic Ground Environment (SAGE) operations began in 1961, initially feeding data to DC-08 at Richards-Gebaur AFB, Missouri. After joining, the squadron was redesignated as the 789th Radar Squadron (SAGE) on 1 January 1962. 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. A second height-finder radar (AN/FPS-6A) was installed in 1962. On 31 July 1963, the site was redesignated as NORAD ID Z-71.

In addition to the main facility, Omaha AFS operated one AN/FPS-18 Gap Filler site:

  • Dallas Center AFS, IA (P-71D) Lua error in Module:Coordinates at line 668: callParserFunction: function "#coordinates" was not found.

Dallas Center was taken over in 1957 after its closure as M-122. It was operated until its final closure in December 1967.

In 1964 the AN/FPS-20A radar was upgraded to become an AN/FPS-66, then updated again to an AN/FPS-66A in 1967. The 789th Radar Squadron (SAGE) was inactivated 8 September 1968, and the search radar was transferred to the FAA. Today, Omaha AFS is an FAA site, still using the Air Force AN/FPS-66A radar as part of the Joint Surveillance System (JSS)
