Winslow Air Force Station Winslow Air Force Station ( ADC ID : M - 93 ) is a closed United States Air Force General Surveillance Radar station . It is located south - southeast of Winslow , Arizona . It was closed in 1963 . History . Winslow Air Force Station was established in 1954 by Air Defense Command as one of a planned deployment of forty - four Mobile radar stations to support the permanent ADC Radar network in the United States sited around the perimeter of the country . This deployment was projected to be operational by mid - 1952 . Funding , constant site changes , construction , and equipment delivery delayed deployment . This site became operational in April 1955 when the 904th Aircraft Control and Warning Squadron was assigned to the station . Winslow became operational in 1956 with the squadron using an AN / FPS - 8 search radar , 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 . In 1958 an AN / FPS - 6 A height - finder radar was added . During 1961 Winslow AFS joined the Semi Automatic Ground Environment ( SAGE ) system , feeding data to DC - 21 at Luke AFB , Arizona . After joining , the squadron was redesignated as the 904th Radar Squadron ( SAGE ) on 15 October 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 . Also in 1961 , an AN / FPS - 6 B was added . An AN / FPS - 64 was installed reportedly in 1963 , but never became operational . During the AN / FPS - 64 installation in a new tower , the AN / FPS - 8 was replaced by an AN / MPS - 11 on a temperate tower . In addition to the main facility , Winslow operated several AN / FPS - 14 Gap Filler sites : In March 1963 the Air Force ordered Winslow closed ; operations ceased 31 May 1963 , the station being closed on 1 August . The Air Force transferred the property to the Department of the Interior , Bureau of Indian Affairs ( BIA ) , by Letter of Transfer dated 9 December 1964 , effective 11 December 1964 . Beginning in 1966 , the former Winslow Air Force Station was home to a training center for the US Job Corps under the control of the Navajo Nation , and housed several hundred teachers , support personnel , and family members , and approximately one hundred inner - city at risk youth . Under the program , inner - city youth were brought to this remote site and trained in heavy - equipment job skills and also earned their GED high school equivalency degrees . The site was closed in 1969 under orders from then - President Nixon . The Navajo Tribe then used the station as a work center for the maintenance of schools within commuting distance until about 1978 . After the site ' s closure in 1978 , the site was thoroughly vandalized . Between 1990 and 1992 all structures associated with the former Winslow Air Force Station Site were removed by the BIA . Approximately 1 . 2 million dollars were spent on building demolition and removal , and cleanup of environmental hazards . Asbestos containing building materials were removed and disposed of prior to building demolition . In addition , two 15 , 000 gallon underground storage tanks were removed for disposal , two transformers were disposed of as PCB - contaminated , and sulfuric acid which was stored on the site was removed for disposal , and the site was restored it to its natural state . Except for some roads , the entire site has been obliterated ; today no remains of the station or radars are left . Air Force units and assignments . Units . Assignments :
