Chandler Air Force Station is a closed United States Air Force General Surveillance Radar station. It is 2.2 miles (3.5 km) south of Chandler, Minnesota, on the Buffalo Ridge in section 13 of Moulton Township, Murray County. It was closed in 1969.

History

In late 1951 Air Defense Command selected the site as one of twenty-eight radar stations built as part of the second segment of the permanent radar surveillance 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 second segment 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 787th Aircraft Control and Warning Squadron was activated on 27 June 1951 under the 31st Air Division. The site was equipped with AN/FPS-3 and AN/FPS-4 radars, 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.

It was redesignated Chandler Air Force Station on 1 December 1953. By 1959 these sets had been replaced by AN/FPS-20 and AN/FPS-6 radars, and the AN/FPS-20 set was upgraded and redesignated as an AN/FPS-64, and a second height-finder radar (AN/FPS-26) was added in 1961.

During 1961 Chandler AFS joined the Semi Automatic Ground Environment (SAGE) system, initially feeding data to DC-11 at Grand Forks AFB, North Dakota. After joining, the squadron was re-designated as the 787th Radar Squadron (SAGE) on 1 April 1961. 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.

Chandler AFS was later switched to SAGE Data Center DC-22 at Sioux City AFS, Iowa in 1963. On 31 July 1963, the site was redesignated as NORAD ID Z-18. In 1965 Chandler AFS was operating an AN/FPS-27 set, and the AN/FPS-64 was deactivated.

The Air Force ordered radar operations to cease on 2 July 1969, and deactivated the 787th Radar Squadron on 30 September 1969. Air Force teams dismantled and removed the radars and communications equipment throughout the summer of 1969. The domes came down from the two height-finder radars, leaving only one dome remaining over the search radar. A small unit stayed behind for over a year to run that radar for the Federal Aviation Administration.

The government subsequently sold the radar site to a developer and the housing area to a group of investors. Buyers removed the homes and the developer salvaged materials from the radar site, but was unable to find a commercial tenant or buyer, Today what was Chandler Air Force Station has been obliterated, being demolished in June 1993 after sitting derelict for decades. A radio transmitter station now stands on the site, and what appears to be a large overgrown pile of concrete on the site which may be the remains of the Air Force structures. The site is located at 339 State Highway 91, Chandler MN 56122 under the county-wide 9-1-1 address system.
