History
The personnel of the 20th SPCS operate the Air Force Space Surveillance System and maintain the AN/FPS-85 radar, the Air Force's only phased-array radar dedicated to tracking earth-orbiting objects. The AN/FPS-85 radar can track approximately 90 percent of all manmade objects in earth orbit. The radar can track near-earth objects the size of a softball moving at 300 miles (500 km) and deep space objects the size of a basketball moving at 22,300 nautical miles (41,300 km) above earth. Located at Site C-6 on Eglin, the squadron is a geographically separated unit of the 21st Space Wing and the only Air Force Space Command unit on Eglin.

Famous quotes containing the word history:
“We are told that men protect us; that they are generous, even chivalric in their protection. Gentlemen, if your protectors were women, and they took all your property and your children, and paid you half as much for your work, though as well or better done than your own, would you think much of the chivalry which permitted you to sit in street-cars and picked up your pocket- handkerchief?”
—Mary B. Clay, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 3, by Susan B. Anthony and Ida Husted Harper (1902)
“The steps toward the emancipation of women are first intellectual, then industrial, lastly legal and political. Great strides in the first two of these stages already have been made of millions of women who do not yet perceive that it is surely carrying them towards the last.”
—Ellen Battelle Dietrick, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 13, by Susan B. Anthony and Ida Husted Harper (1902)
“The history of all hitherto existing society is the history of class struggles.”
—Karl Marx (1818–1883)
