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

Provides midcourse coverage for the
Ballistic Missile Defense System. Detects sea-launched or intercontinental ballistic missiles; Classifies reentry vehicles and other missile objects. Provides real-time information to Fire

223:
Has one radar face providing 136° of azimuth coverage. The radar face is approximately 95 feet in diameter; overall radar height is 120 feet. Detects objects out to 2000 miles. It operates in the L-band
220:
Provides tracking of threat ballistic missiles sufficiently accurate to commit the launch of interceptors and to update the target tracks to the interceptor while the interceptor is in flight
151:(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.
155:
The first letter of the three-letter code denotes the type of platform hosting the electronic device, where A=Aircraft, F=Fixed (land-based), S=Ship-mounted, and T=Ground transportable.
