The 9 MWS controlled the Southeast facing AN/FPS-123 PAVE PAWS radar site,[1] providing warning to detect sea-launched and intercontinental ballistic missiles.

Later use of the radar included support for the USAF space surveillance network by providing satellite vehicle surveillance, tracking, and radar space object identification.

With these added mission areas, the unit was redesignated 9th Space Warning Squadron (9 SWS).

[2] As the likelihood of sea-based missile attacks from the Gulf of Mexico decreased, and the low probability of missile attacks from the South, the United States Air Force decided to close southern-facing PAVE PAWS sites at Robins AFB and Eldorado AS, Texas.

Two radar faces, one each from Robins AFB and Eldorado AS, were moved to Clear AFS, Alaska as part of the BMEWS upgrade in 1998.
