St. Mihiel was a troopship built for the United States Shipping Board by the American International Shipbuilding Corporation at Hog Island, Pennsylvania. The ship was operated from 1922 until mid-1940 as USAT St. Mihiel by the Army Transport Service. In July 1941 the ship was transferred to the Navy which commissioned her USS St. Mihiel with the hull number AP-32. In November 1943, she was transferred back to the Army and converted into the hospital ship, USAHS St. Mihiel.
