History of Omaha AFS, NE

The 789th AC&W Squadron activated an AN/CPS-4 and AN/FPS-3 at this site in April 1952. 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. SAGE operations began in 1961. A second height-finder radar (AN/FPS-6A) was installed in 1962. An AN/FPS-27 FD search radar was planned, but was subsequently cancelled. 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 deactivated 8 September 1968, and the search radar was transferred to the FAA.
