USS Beaufort, a 1769 gross ton cargo ship, was built at Lubeck, Germany, in 1909 as the commercial collier Rheingraf. Later renamed Rudolf Blumberg, she took refuge in the United States when the First World War's outbreak in August 1914 made the high seas too dangerous for German merchant ships. When the U.S. entered the conflict in April 1917, she was seized at Pensacola, Florida. Turned over to the Navy and refitted at New Orleans, Louisiana, she placed in commission as USS Beaufort in September 1917. Later given the registry ID # 3008, she operated in European waters until March 1919 carrying coal across the English Channel. Upon her return to the U.S., the ship was assigned to the Atlantic Fleet Train. She received the hull number AK-6 in mid-1920 and performed logistics functions along the East Coast and in the Caribbean until decommissioned in December 1925. USS Beaufort was sold in October 1926. Her new owners, a Norwegian commercial firm, nenamed her Fjorden. She was reportedly lost on 12 April 1933.
