The AN/FPS-108 Cobra Dane radar is a passive electronically scanned array installation operated by Raytheon for the United States Air Force at Eareckson Air Station on the island of Shemya, Alaska.[1] This radar system was built in 1976 and brought on-line in 1977 for the primary mission of intelligence gathering in support of verification of the SALT II arms limitation treaty. Its single face radar with a 29 m (95 ft) diameter phased array radar antenna faces the Kamchatka Peninsula and Kura Test Range. Cobra Dane operates in the 1215–1400 MHz band.[2]

The "Cobra" designation indicated a General Defense Intelligence Program.[3]

It initially employed a Control Data Corporation Cyber 74 mainframe computer for data processing.[4] Data from the radar is sent to the North American Aerospace Defense Command (NORAD) at Peterson Air Force Base, Colorado. It is also listed as a partner of the NASA Orbital Debris Program Office and works with the Missile Defense Agency,[1] under the control of the 21st Operations Group.[5]
