Receiving the Defense Secretary's approval on 21 July, the Air Force directed the Corps of Engineers to proceed with construction.

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 addition to the main facility, Williams Bay operated the following AN/FPS-18 Gap Filler sites: Williams Bay ceased operations in January 1960 as a budget reduction move, the mission and organization being transferred to the existing United States Army Arlington Heights facility C-80DC for the Nike Missile air-defense system, as part of the Chicago-Gary Defense Area.

In 1974, the State sold the site to private interests, currently operating it as the Williams Bay Industrial Park, using some of the old USAF buildings.

There is a small Wisconsin Historical Society Marker on the former air force station honoring the 755th AC&W Squadron.
