Raytheon Awarded $511 Million Contract for Cobra Dane Radar

Raytheon Intelligence, Information and Services has been awarded a $511 million indefinite-delivery/indefinite-quantity (IDIQ) contract for the Cobra Dane radar.

This contract provides the tasks required to operate, maintain, and sustain the Cobra Dane radar. Work will primarily be performed at Eareckson Air Station, Shemya, Alaska, and is expected to be complete by March 2025.

This award is a result of a competitive acquisition and three offers were received. No funds are being obligated at the time of award. The U.S. Air Force Life Cycle Management (AFLCMC) located at Peterson Air Force Base, Colorado, is the contracting activity.

AN/FPS-108 Cobra Dane

AN/FPS-108 Cobra Dane radar is a ground-based passive electronically scanned array (PESA) installation operated by Raytheon for the United States Air Force (USAF) at Eareckson Air Station on the island of Shemya, Aleutian Islands, Alaska. This radar system was built in 1976 and brought on-line in 1977.

The primary mission of COBRA DANE is to collect radar metric and signature data on foreign ballistic missile events during exo­atmospheric and early endo-atmospheric portions of flight and on selected space launches in early orbit in support of treaty monitoring (SALT II arms limitation treaty), force modernization, and missile defense. Additional missions include collecting space surveillance data on new foreign launches and both known (cataloged) and unknown (uncatalogued) satellites in low-earth orbit for the Space Situational Awareness (SSA) Operations Cell.

Its single face radar with a 29 m (95 ft) diameter phased array radar antenna (location: 52.7373°N 174.0914°E) faces the Kamchatka Peninsula and Kura Test Range. Cobra Dane operates in the L-band (1175-1375 MHz) band.

The phased array has the capability to track and record data on as many as 120 objects simultaneously. COBRA DANE will transition into Missile Defense mode automatically upon detection of a threatening missile or transition upon receipt of an alert message from the GFC. At all other times, COBRA DANE primarily supports the Space Surveillance Mission.

The “Cobra” designation indicated a General Defense Intelligence Program.

The radar initially employed a Control Data Corporation Cyber 74 mainframe computer for data processing. 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, under the control of the 21st Operations Group.
