The USS Rappahannock (AF-6) was a Rappahannock-class stores ship acquired by the United States Navy during World War I. Originally launched in 1913 as the SS Pommern by Bremer-Vulcan yards in Vegesack, Germany, she was built for the North German Lloyd Line as part of the Rheinland class, serving the Australia freight route via the Cape of Good Hope. Following the outbreak of World War I, she was voluntarily interned in Honolulu and later seized by the U.S. upon America's entry into the war. Converted for naval service, she was delivered to the U.S. Navy on December 7, 1917, and commissioned the following day as USS Rappahannock. As a part of the Naval Overseas Transportation Service, she primarily functioned as an animal transport, carrying horses and steers on the hoof to support American Expeditionary Force troops in Europe. Her operational highlights include completing her fourth transatlantic run to France on November 16, 1918, just five days after the armistice, underscoring her role in logistical support during wartime. After her military service, Rappahannock was transferred to the Train, Atlantic Fleet, and continued to operate between North America and Europe, undertaking additional voyages before being placed in temporary reserve status at Portsmouth in 1919. She was reactivated in June 1922 with the designation AF-6, resuming cargo transport duties for both Atlantic and Pacific Fleets until her decommissioning on December 10, 1924. She remained in reserve at Mare Island until she was struck from the Navy list in July 1933. Subsequently sold to the Luckenbach Steamship Co., she was renamed William Luckenbach and operated through World War II. In 1946, she was sold to the Italian firm Giacomo Costa fu Andrea, transformed into a passenger carrier named Maria C., and served as part of Costa Lines' South American route network. After re-routing to North American service, she was withdrawn in 1952 and scrapped in 1953. The USS Rappahannock's service exemplifies the vital logistical role of support ships in wartime and maritime commerce.
