USNS Patuxent (T-AO-201) is a Henry J. Kaiser-class underway replenishment oiler operated by the Military Sealift Command to support ships of the United States Navy. Patuxent, the fifteenth ship of the Henry J. Kaiser class, was laid down at Avondale Shipyard, Inc., at New Orleans, Louisiana, on 16 October 1991 and launched on 23 July 1994. She was the first of three ships in the class of eighteen—the other two being and —to be built with a double hull required by the Oil Pollution Act of 1990. Hull separation is at the sides and at the bottom, reducing her liquid cargo capacity by about from that of the 15 single-hull ships in the class.
