The USS Chiwawa (AO-68) was a Kennebec-class oiler constructed for the United States Navy during World War II. Launched on June 25, 1942, by Bethlehem Steel Co. at Sparrows Point, Maryland, she was originally named SS Samoset under a Maritime Commission contract. The vessel was acquired by the Navy on December 24, 1942, and commissioned the same day, reporting to the Atlantic Fleet. The Chiwawa was a T3-S-A1 design tanker, characterized by its length exceeding 500 feet, single-screw steam propulsion, and status as the first of its design type. The ship’s service commenced with transatlantic convoy operations, including loading oil at Aruba and participating in convoy runs to Casablanca, the British Isles, and North Africa. Notably, she was part of a convoy attacked by a wolfpack east of the Azores but survived due to aircraft from Port Lyautey, Morocco. Throughout 1943 and 1944, she ferried oil along the East Coast of the U.S., across the Atlantic to Europe, and to North Africa, supporting Allied operations, including fueling ships involved in the invasion of southern France. In August 1944, she arrived at Naples and served as a station tanker at Okinawa from August to November 1945, fueling the U.S. 7th Fleet at sea. After the war, the USS Chiwawa returned to the U.S., was decommissioned on May 6, 1946, and transferred to the Maritime Commission. She was laid up in the National Defense Reserve Fleet until 1961. Subsequently, she was converted into a straight-decked bulk freighter for Great Lakes service, renamed SS Walter A. Sterling, and later SS William Clay Ford (II), and SS Lee A. Tregurtha. Modernized with diesel engines, she remains active today as a cargo vessel on the Great Lakes, owned by Interlake Steamship Company. The USS Chiwawa earned two battle stars for her World War II service, highlighting her significant contribution to wartime logistics and maritime operations.
