About this Unit
TUSLOG Detachment 117 was a United States Air Force unit stationed at Çiğli Air Base near Izmir, Turkey, during the Cold War era. Established in the 1950s under the umbrella of "The United States Logistics Group" (TUSLOG), the detachment supported NATO operations and facilitated U.S. military logistics and communications in the region. Its personnel contributed to intelligence gathering, air operations coordination, and maintained a vital presence during periods of regional tension. Detachment 117 remained active through the 1970s, playing a key role in strengthening U.S.-Turkish military cooperation until its eventual deactivation as American force posture in Turkey evolved.
