About this Unit
NAVCOMSTA Sidi Yahia, short for Naval Communications Station Sidi Yahia, was a United States Navy communications facility located near Sidi Yahia el Gharb in Morocco. Commissioned in the early 1950s, the station played a vital role during the Cold War, providing critical communications support for the U.S. Sixth Fleet and other naval operations in the Mediterranean and Atlantic regions. Operated under the United States Naval Communications Command, the base maintained secure lines of communication, supported naval intelligence, and relayed messages between Washington, D.C., and deployed forces. NAVCOMSTA Sidi Yahia was eventually closed in the early 1970s as part of the U.S. withdrawal from its Moroccan bases following renegotiations with the Moroccan government.
