USNS American Explorer (T-AOT-165) was a tanker built for the United States Military Sea Transport Service. The tanker was built by Ingalls SB of Mississippi in 1958, and at the time her keel was laid, the vessel was intended to be the world's first nuclear-powered tanker, but was completed with a conventional steam power plant. The ship was transferred to the US Maritime Administration in 1984 and was part of the US Reserve Fleet, Beaumont Reserve Fleet, Texas. American Explorer was sold for scrap on 8 July 2008 to the Southern Scrap Metal Corporation in New Orleans, Louisiana. On 13 August, two weeks before Hurricane Gustav struck the Southeastern Louisiana coastline, the tanker was moved to New Orleans' Industrial Canal.

USNS Courier was a cargo ship of the National Defense Reserve Fleet. The cargo ship was built by Sun Shipbuilding and Drydock Company, Chester, Pennsylvania, at the request of the US Maritime Administration in 1962. The ship was 470 ft in length and has a breath of 73 and weighs 11420 tons, empty. The ship was originally administered by American Export Lines under the civilian name SS Export Courier and eventually became part of the James River Reserve Fleet. The company ran into financial trouble in 1977. Before 1981, Farrell Lines, which took over parts of the dissolved American Export Lines, transferred administration of the Courier to the Military Sealift Command, which renamed the ship USNS Courier. The ship was officially accepted as part of the Maritime Administration in February 1983. From 1981 it was stationed with the Beaumont Reserve Fleet or docked at Port Neches, Beaumont Texas. Service records indicate repairs after Operation Desert Storm. In 2001 the ship was transferred to the National Defense Reserve Fleet and remained in this status until July 2008 when it was sold to Southern Scrap Metal Corporation of New Orleans, Louisiana and subsequently transferred to New Orleans' Industrial Canal on 13 August, a little more than two weeks before Hurricane Gustav reached Louisiana's southeastern coast.
