The USS Unicoi (IX-216) was originally built as the SS Unicoi in 1920 by the Oscar Daniels Co. in Tampa, Florida. This American cargo ship was part of the Design 1027 class, measuring 416 feet in length with a beam of 54 feet 6 inches and a draft of 27 feet 1 inch. She was assessed at 9,500 deadweight tons (DWT) and powered by a single diesel engine manufactured by Worthington Pump & Machinery Corporation, which drove a single screw propeller. Initially owned by the United States Shipping Board and later the United States Maritime Commission, she was renamed Excelsior in the late 1930s or early 1940s but reverted to Unicoi by 1942. During World War II, Unicoi played a notable role in convoy operations along the Atlantic coast. On 15 July 1942, she was part of Convoy KS 520 off Cape Lookout, North Carolina, when German U-boat U-576 torpedoed three ships in the convoy. The ship's armed guard responded swiftly, firing a shell that hit the submarine, and aircraft overhead dropped depth charges, contributing to the sinking of U-576. The vessel continued her service, joining convoys to Caribbean ports and making a voyage through the Panama Canal to New Zealand and the Philippines. In 1944, she was transferred under the control of the War Shipping Administration and operated by American Export Lines in the Pacific theater. She was acquired by the U.S. Navy on 23 April 1945, commissioned as USS Unicoi (IX-216), and assigned to Service Squadron 8. Due to her age and condition, she underwent extensive overhaul at Seeadler Harbor before serving as a mobile dry storage ship. Notably, she ran aground at Green Island in August 1945 but was refloated without damage. After supporting operations in the Philippines and the Pacific, she returned to the United States, arriving in San Francisco in February 1946. She was decommissioned on 16 April 1946, struck from the Navy Register, and sold for scrapping. The USS Unicoi’s service highlights her versatility and contribution to maritime logistics during wartime.
