Eritrea, Kagnew Station, a crucial U.S. military intelligence and communications base operational in Eritrea (then Ethiopia) during the Cold War. The first source offers a personal narrative from a reunion of former Kagnew service members, reflecting on the base's history as a major Army Security Agency (ASA) deep space listening post and exploring the enduring geopolitical impact of the U.S. presence in the Horn of Africa. The second and third sources focus specifically on STONEHOUSE, the highly specialized National Security Agency (NSA) deep space tracking facility located within Kagnew Station, detailing its construction with massive antennae, its primary mission of intercepting Soviet deep space and planetary mission telemetry from 1965 to 1975, and its eventual closure due to political instability in Ethiopia. Kagnew Station was central to the early growth of the American surveillance state and its competition with the Soviet Union in space.
