Williams Bay Air Force Station

 military, radar station, abandoned / shut down, United States Air Force

The now closed Williams Bay AFS was opened in 1951 as the 755th AC&W Squadron began operating a pair of AN/CPS-6B radars. An AN/FPS-6 height-finder radar was added in 1959. This station ceased operations in January 1960 when the 755th Radar Squadron relocated to the Army radar site at Arlington Heights, IL (MM-4). Williams Bay AFS itself was reactivated as a gap-filler site, supporting the radar site at Arlington Heights.

The Air Force Station was excessed on 20 September 1961 after the mission of the facility was moved to Arlington Heights, IL. Of the original 45.83 acres, 45.04 were sold to the State of Wisconsin in 1962, and used as a Prisoner Re-Release Center for 8 to 10 years. In 1974, the State sold the site to private interests, currently operating it as the Williams Bay Industrial Park. Several buildings have been renovated for industrial use, and the former family housing units are maintained as private residences. A remaining 0.79 acres, located in the southwest corner of the Air Force Station property, was retained by the Air Force for use as the Williams Bay Gap Filler Annex. The Gap Filler Annex was declared excess in 4 January 1968, and sold to private ownership in 5 November 1969, where it is now a private residence.
