SS Regulus (T-AKR 292) 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 A.G. Weser in Bremen, West Germany, hull no. 1383, for Sea-Land Service, Inc. and named SS Sea-Land Commerce, USCG 545200, IMO 7302897.[1] Due to her high operating cost, she was sold to the United States Navy on 27 October 1981 as USNS Regulus (T-AK-292).
In keeping with the pattern of naming the Algol-class ships after bright stars, the Regulus was named after Regulus, the brightest star in the constellation Leo and one of the brightest stars in the night sky.
Conversion began on 29 June 1984 at National Steel and Shipbuilding in San Diego, California. Her cargo hold was redesigned into a series of decks connected by ramps so vehicles could 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. She was delivered to the Military Sealift Command on 28 August 1985 as USNS Regulus (T-AKR 292).
When not active, Regulus 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. Regulus 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.
On 1 October 2007, Regulus was transferred to the United States Maritime Administration. On 1 October 2008, she was transferred to the Ready Reserve Force, losing her USNS designation. If activated, Regulus will report to the Military Sealift Command.
