The United States Air Force's 20th Space Control Squadron is a space control unit located at Eglin AFB, Florida.


The mission of the 20th Space Control Squadron is to detect, track, identify, and report near earth and deep space objects in earth's orbit, and provide space object identification data in support of United States Strategic Command's space control mission.


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.
