SS Altair (T-AKR 291) is an Algol class vehicle cargo ship that is currently maintained by the United States Maritime Administration as part of the Military Sealift Command's Ready Reserve Force (RRF). She was built as a high speed container ship by Rheinstahl Nordseewerke in Emden, West Germany, hull no. 431, for Sea-Land Service, Inc. and named SS Sea-Land Finance, USCG ON 550722, IMO 7315571.[1][2] Due to her high operating cost, she was sold to the United States Navy on 5 January 1982 as USNS Altair (T-AK-291).[3]

In keeping with the pattern of the naming the Algol-class ships after bright stars, the Altair was named after Altair, the brightest star in the constellation Aquila and the twelfth brightest star in the night sky.

Conversion

Conversion began on 28 July 1984 at Avondale Shipyards in New Orleans, Louisiana. Her cargo hold was redesigned into a series of decks connected by ramps so vehicles can be driven into and out of the cargo hold for fast loading and unloading. She was also fitted with two sets of two cranes; one set located at midship capable of lifting 35 tons, and another set located aft capable of lifting 50 tons.[2] She was delivered to the Military Sealift Command on 13 November 1985 as USNS Altair (T-AKR 291).[4]

Service

When not active, Altair is kept in reduced operating status due to her high operating cost. If needed, she can be activated and ready to sail in 96 hours.[5] Altair took part in the Persian Gulf War in 1990. Along with the other seven Algol class cargo ships, she transported 14 percent of all cargo delivered between the United States and Saudi Arabia during and after the war.[6]

On 1 October 2007, Altair was transferred to the United States Maritime Administration. On 1 October 2008, she was transferred to the Ready Reserve Force, losing her USNS designation.[6][7] If activated, Altair will report to the Military Sealift Command.[3]
