U.S. Naval Intermediate Support Base Thuan An (1971)


Situated on an island near Tan My in the Republic of Vietnam, the naval installation at Thuan An provided logistic support to American and Vietnamese naval forces during the Vietnam War.

When American forces withdrew from the Hue area in early 1971 as part of the lessening of U.S. involvement in the conflict, the logistic task of the Hue, Phu Bai, and Tan My bases were concentrated at the newly constructed Thuan An intermediate support base. The Navy’s Seabees prepared facilities for the provision of fuel. maintenance, administrative, financial, and other support of river and coastal patrol boats in northern I Corps Tactical Zone. In September 1971 the Vietnamese Navy relieved American naval forces at Thuan An and the intermediate support base was disestablished.
