Its predecessor, Air Defense Command, was established in 1946, briefly inactivated in 1950, reactivated in 1951, and then redesignated ''Aerospace'' rather than ''Air'' in 1968. Its mission was to provide air defense of the Continental United States (CONUS). It directly controlled all active measures, and was tasked to coordinate all passive means of air defense.

Winslow Air Force Station (ADC ID: M-93) is a closed United States Air Force General Surveillance Radar station. It is located in Coconino County, Arizona, west-northwest 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.

904th Radar Squadron
9 (nine) is the natural number following and preceding . Evolution of the Arabic digit In the beginning, various Indians wrote a digit 9 similar in shape to the modern closing question mark without the bottom dot. The Kshatrapa, Andhra and Gupta started curving the bottom vertical line coming up with a -look-alike. The Nagari continued the bottom stroke to make a circle and enclose the 3-look-alike, in much the same way that the sign @ encircles a lowercase ''a''. As time went on, the enclosing circle became bigger and its line continued beyond the circle downwards, as the 3-look-alike became smaller. Soon, all that was left of the 3-look-alike was a squiggle. The Arabs simply connected that squiggle to the downward stroke at the middle and subsequent European change was purely cosmetic. While the shape of the glyph for the digit 9 has an ascender in most modern typefaces, in typefaces with text figures the character usually has a descender, as, for example, in . The mo ...
