Upgraded Early Warning Radars (UEWR) provide detection, tracking, and classification data to the Ballistic Missile Defense System (BMDS). Currently, three UEWRs are deployed by the United States, located at Beale AFB in California, Fylingdales in the United Kingdom, and Thule AFB in Greenland. The Missile Defense Agency is also working to upgrade the Early Warning...| Missile Threat
The Space Tracking and Surveillance System (STSS) is a space-based system developed and operated by the Missile Defense Agency (MDA) that detects and tracks ballistic missiles. This system is an experimental component of the U.S. Ballistic Missile Defense System (BMDS) and STSS serves as a complement to other U.S. space-based platforms and was intended to...| Missile Threat
The Sea-Based X-band Radar (SBX) is a unique radar housed on a decommissioned North Sea oil rig. The SBX produces very high resolution images of incoming threat clouds, which helps BMD interceptors discriminate between lethal objects and debris. The SBX has contributed to 12 tests of the GMD system and provided tracking and kill assessment for...| Missile Threat
The Long Range Discrimination Radar (LRDR) is a long-range, midcourse tracking radar designed to provide continuous coverage and improved discrimination capabilities to defend the U.S. homeland. The radar is intended to support the layered U.S. BMD defense system to defend against threats emanating from the Pacific and will provide more deployment flexibility for the Sea-Based...| Missile Threat
The Cobra Dane Radar Upgrade is an L-band radar located at Shemya Island, Alaska at Eareckson Air Station. It has a single face, 95 feet in diameter, providing 136-degree azimuth coverage. It was originally designed as a missile tracking radar for Soviet missile tests, but was upgraded to perform missile defense missions in 2004. The radar face can...| Missile Threat
The AN/TPY-2 (Army-Navy Transportable Radar Surveillance) is a high-resolution, X-band radar built specifically for missile defense. Developed alongside the THAAD ballistic missile defense system, the AN/TPY-2 is capable of tracking targets at long range and cueing other U.S. missile defense systems. The U.S. Army took delivery of its first production AN/TPY-2 in 2004 and currently...| Missile Threat
