USS Muscoota, a 1370-ton Mohongo class iron "double-ender" steam gunboat, was built at Greenpoint, New York. Commissioned in January 1865, she was at Norfolk, Virginia, in May 1865 when ordered to Key West as part of an effort to prevent Confederate President Jefferson Davis escaping abroad. Muscoota remained in the Gulf of Mexico area at least until August 1866, when she was sent north in response to a serious outbreak of Yellow Fever among her crew. Sold in June 1869, she subsequently became the merchant steamship Tennessee.
