Kagnew Station was a United States Army installation in Asmara, Eritrea (formerly Ethiopia) on the Horn of Africa. The installation was established in 1943 as a U.S. Army radio station, taking over and refurbishing a pre-existing Italian naval radio station, Radio Marina, after Italian forces based in Asmara surrendered to the Allies in 1941. Kagnew Station operated until April 29, 1977, when the last Americans left. The station was home to the United States Army's 4th Detachment of the Second Signal Service Battalion.
