The SS Altair (T-AKR 291) is an Algol-class vehicle cargo ship currently maintained by the United States Maritime Administration as part of the Military Sealift Command's Ready Reserve Force. Originally constructed as a high-speed container vessel, she was built by Rheinstahl Nordseewerke in Emden, West Germany, with hull number 431. The ship was initially named SS Sea-Land Finance and operated by Sea-Land Service, Inc. Her design prioritized rapid cargo transfer, featuring a redesigned cargo hold with multiple decks connected by ramps, allowing vehicles to drive directly into and out of the hold for efficient loading and unloading. The vessel was equipped with two sets of cranes—one set at midship capable of lifting 35 tons and another at the aft capable of lifting 50 tons—enhancing her cargo handling capabilities. Due to her high operating costs, she was sold to the U.S. Navy on 5 January 1982 and was renamed USNS Altair, after the brightest star in the constellation Aquila, following the Algol-class tradition of naming ships after luminous stars. Her conversion into a military cargo ship began on 28 July 1984 at Avondale Shipyards in New Orleans, Louisiana, culminating in her delivery to the Military Sealift Command on 13 November 1985. As part of her service, Altair played a significant role during the Persian Gulf War in 1990, where she, along with her sister ships, transported approximately 14 percent of all cargo delivered between the United States and Saudi Arabia during the conflict. She is maintained in a reduced operating status due to the high costs of operation, initially at ROS-3 (96 hours readiness), now at ROS-5 (120 hours). On 1 October 2007, the vessel was transferred to the United States Maritime Administration and, a year later, to the Ready Reserve Force, losing her USNS designation. When activated, she reports to the Military Sealift Command Atlantic Fleet and remains berthed at Marrero, Louisiana, alongside her sister ship SS Bellatrix. Her design and operational history underscore her importance as a rapid deployment vessel within the U.S. maritime logistics framework.
