The AN/FPS-108 Cobra Dane radar system collects and disseminates exoatmospheric, multiple-object intelligence data.

The Cobra Dane is a large L-band, computer-controlled, phased-array radar system with local, wide- and narrow-band communication systems and an operations and test complex. The system provides 120-degree coverage of a 2,000-mile corridor that spans the eastern Russian peninsula and northern Pacific Ocean. Its digital data and voice communication systems interface with the National Air Intelligence Center (NAIC) and the North American Aerospace Defense Command (NORAD).

The Cobra Dane collects exoatmospheric, multiple-object intelligence data on Russian reentry vehicles and can extract and reduce the data on site. The system also provides early-warning and attack assessment for missiles that would impact the continental United States and detects and catalogs satellites for the U.S. Air Force’s Spacetrack systems.
