About LEE A. TREGURTHA
USS Chiwawa (AO-68) is a former T3-S-A1 Kennebec-class oiler constructed for the United States Navy during World War II. She was the only U.S. Navy ship named for the Chiwawa River in Washington. Chiwawa was launched 25 June 1942 by Bethlehem Steel Co., Sparrows Point, Maryland, under a Maritime Commission contract as SS Samoset, sponsored by Mrs. H. G. Smith, acquired by the Navy 24 December 1942 and commissioned the same day, reporting to the Atlantic Fleet. Chiwawa was designated a T3-S-A1 design, where "T" stood for tanker, "3" meant longer than 500 feet (150 m), "S" stood for single-screw steam propulsion, and "A1" meant first design of its kind.
