AN/FSS-7 radars are installed at which sites as part of UEWR?

• A. Eglin AFB, Florida; El Dorado SFS, Texas; and Warner-Robbins AFB, Georgia
• B. Clear SFS Alaska; Thule AB Greenland; Fylingdales UK
• C. Beale AFB California; Cape Cod SFS Maine; Cavalier SFS North Dakota
• D. Diego Garcia; Maui AMOS; Kwajalein Atoll

Answer: (A)

The question tests knowledge of where the AN/FSS-7 radar units, as part of the Upgraded Early Warning Radar (UEWR) network, are deployed. The AN/FSS-7 is a fixed, long-range radar sensor used to provide early warning and tracking data for ballistic missiles, feeding the system that protects North America with timely launch detection.

The correct sites are Eglin Air Force Base in Florida, El Dorado Site (El Dorado SFS) in Texas, and Warner Robins Air Force Base in Georgia. This trio represents the UEWR installations that were designated to cover gaps and provide redundant, wide-area detection across the southern United States, forming the core fixed sensor portion of the UEWR network.

Other site groupings correspond to different early-warning or defense systems. For example, locations like Clear SFS in Alaska, Thule Air Base in Greenland, and Fylingdales in the UK were associated with earlier or separate early warning architectures (such as BMEWS/PAVE PAWS ecosystems) rather than the AN/FSS-7 UEWR network. The other options likewise align with different radar programs or defense tasks, not the UEWR AN/FSS-7 deployments.
