About this Unit
Naval Communication Station (NAVCOMSTA) Asmara was a United States Navy communications facility located near Asmara, in what was then Ethiopia (now Eritrea). Established in the early 1950s during the Cold War, the base served as a critical signals intelligence and communications relay site due to its strategic location in the Horn of Africa. NAVCOMSTA Asmara provided essential support for U.S. Navy operations in the region, monitoring Soviet naval activity and facilitating secure communications between U.S. military units. The station remained active until 1977, when deteriorating U.S.-Ethiopian relations and regional instability led to its closure and the withdrawal of American personnel.
Historical Facts
•
Strategic Location: NAVCOMSTA Asmara (U.S. Naval Communications Station, Asmara) was situated in Asmara, Eritrea (then part of Ethiopia), taking advantage of the high altitude (over 7,600 feet) for superior radio reception and transmission.
•
Cold War Significance: The station played a critical role during the Cold War, intercepting communications from the Soviet Union, Middle East, and Africa. It was a major U.S. intelligence-gathering site in the region.
•
Radio Intercept Powerhouse: NAVCOMSTA Asmara operated as one of the largest U.S. radio listening posts in the world, with an array of antennas and powerful receivers spread across the outlying Kagnew Station complex.
•
Kagnew Station: The base was part of the broader "Kagnew Station," a U.S. Army garrison established in 1943 and later expanded for Navy use. It became a local landmark and economic hub for Asmara.
•
Support to NASA: The station supported NASA’s Mercury, Gemini, and Apollo space programs by relaying telemetry and voice communications as a tracking and communications relay site.
•
Community and Culture: The base created a small American community in Asmara, complete with schools, a movie theater, clubs, and American-style housing for military families.
•
Local Relations: The station employed thousands of Eritrean and Ethiopian civilians, leading to significant cultural exchange and economic impact for the local population.
