About this Unit
U.S. Naval Communications Station Sidi Yahia (USNAVCOMSTA Sidi Yahia), located near Sidi Yahia el Gharb in Morocco, was established in the early 1950s as part of a network of American military bases during the Cold War. The station served as a key communications and relay site for the U.S. Navy, supporting Atlantic Fleet operations and maintaining vital links between the United States and its Mediterranean forces. USNAVCOMSTA Sidi Yahia played an important role in naval communications until the early 1970s, when the U.S. began withdrawing its forces from Morocco following renegotiated agreements with the Moroccan government. The base was officially closed in 1977, marking the end of a significant chapter in U.S.–Moroccan military cooperation.
