Night view of the COBRA DANE radar

The AN/FPS-108 COBRA DANE is a PESA phased array radar installation operated by Raytheon for the United States Space Force (originally for the United States Air Force) at Eareckson Air Station on the island of Shemya, Aleutian Islands, Alaska.[1] The system was built in 1976 and brought online in 1977 for the primary mission of gathering intelligence about Russia's ICBM program in support of verification of the SALT II arms limitation treaty. Its single face 29 m (95 ft) diameter phased array radar antenna 52°44′14N 174°05′29E / 52.7373°N 174.0914°E / 52.7373; 174.0914 faces the Kamchatka Peninsula and Russia's Kura Test Range. COBRA DANE operates in the 1215–1400 MHz band and can track items as small as a basketball sized drone at distances of several hundred miles.[2]

The "COBRA" designation indicates a general Defense Intelligence program.[3]

Classification of radar systems[edit]

Under the Joint Electronics Type Designation System (JETDS), all U.S. military radar and tracking systems are assigned a unique identifying alphanumeric designation. The letters “AN” (for Army-Navy) are placed ahead of a three-letter code.[4]

Thus, the AN/FPS-108 represents the 108th design of an Army-Navy “Fixed, Radar, Search” electronic device.[4][5]

Description[edit]

It initially employed a Control Data Corporation Cyber 74 mainframe computer for data processing.[6] Data from the radar is sent to the North American Aerospace Defense Command (NORAD) at Peterson Space 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.[7]

The Cobra Dane radar has been upgraded to be integrated in the Missile Defenses Agency's (MDA) Ballistic Missile Defense System (BMDS). The improvement includes midcourse BMDS sensor coverage by providing acquisition, tracking, object classification, and data that can be used for cueing, launch of interceptor missiles, and course updates of interceptors while retaining the site's legacy intelligence and space track missions. The Space Force maintains responsibility for the Cobra Dane radar operations, maintenance, and sustainment.[8]
