The Sioux are a confederacy of nomadic tribes that inhabited the plains and prairies from the Great Lakes to the Rocky Mountains and that speak three different dialects, the Lakota, Dakota, and Nakota. This is the fourth ship to bear the name. The first (YT-19) was a tug that served from 1898 until sold in 1921; re-named Nyack in 1918. The second (ID-1766) was a cargo ship that served from 1917-1919. The third (AT-75) Sioux (ATF-75) was a tug that served from 1942 through 1972 and earned four battle stars for World War II service and eight battle stars for service in the Vietnam War.
