The USS Manatee (AO-58)—the second vessel of the United States Navy to bear the name—was a Cimarron-class fleet replenishment oiler named for a river in Florida. Cimarron-class oilers were named after American rivers in the southern United States. Manatee was laid down 28 August 1943 by the Bethlehem Sparrows Point Shipyard, Inc. of Sparrows Point, Maryland, as a Maritime Commission type (T3-S2-A3) tanker hull with a cargo capacity of 146,000 barrels, under Maritime Commission contract (MC hull 724); launched 18 February 1944; sponsored by Mrs. Paul V. McNutt; and commissioned 6 April 1944.
