Large, Medium-Speed Roll-on/Roll-off (LMSR) refers to several classes of the United States' Military Sealift Command (MSC) roll-on/roll-off type cargo ships. Some are purpose-built for military cargo, while others were converted.
The Bob Hope class are a group of seven diesel-powered vessels built at Avondale Shipyard in Louisiana between 1993 and 2001 for MSC. They are 951 ft 5 in (289.99 m) long and 106 ft (32 m) wide.
The Watson class are a group of eight gas-turbine-powered vessels built at National Steel and Shipbuilding Company (NASSCO) in San Diego, California between 1996 and 2002 for MSC. They are 951.4 ft (290.0 m) long and 106 ft (32 m) wide.
The Gordon class are group of two LMSRs. Gordon was built in Denmark in 1972 as MV Jutlandia, and entered commercial service on 1 June 1973. After some time spent in commercial service she was lengthened by Hyundai Heavy Industries in 1984, and later went on to be acquired by the US Navy under a long term charter. She was converted for the Navy at Newport News Shipbuilding and Drydock Company and on delivery to the Navy was assigned to the Military Sealift Command on 23 August 1996 under the name USNS Gordon. [1] They are diesel-powered, 954 ft (291 m) long and 105 ft 9 in (32.23 m) wide ships.
The Shughart class are group of three LMSRs. Shughart was built as Laura Maersk in 1980 in Denmark by Lindovaerftet for A. P. Moller-Maersk Group. She was lengthened in 1987 and again in the early 1990s by Hyundai. On May 7, 1996 Laura Maersk was delivered to Military Sealift Command and was outfitted at NASSCO. They are diesel-powered, 908.8 ft (277.0 m) long and 105.6 ft (32.2 m) wide ships.
Strategic sealift ships are part of the United States Military Sealift Command's (MSC) prepositioning program. There are currently 17 ships in the program, strategically positioned around the world to support the Army, Navy, Air Force, Marine Corps and Defense Logistics Agency. Most are named after Medal of Honor recipients from the service they support. The ships are assigned to two Military Prepositioning Ship (MPS) squadrons located in the Indian Ocean at Diego Garcia and in the Western Pacific Ocean at Guam and Saipan.
The Lewis and Clark class of dry cargo ship is a class of 14 underway replenishment vessels operated by the United States Navy's Military Sealift Command. The ships in the class are named after famous American explorers and pioneers.
The Military Sealift Command (MSC) is an organization that controls the replenishment and military transport ships of the United States Navy. Military Sealift Command has the responsibility for providing sealift and ocean transportation for all US military services as well as for other government agencies. It first came into existence on 9 July 1949 when the Military Sea Transportation Service (MSTS) became solely responsible for the Department of Defense's ocean transport needs. The MSTS was renamed the Military Sealift Command in 1970.
The Algol-class vehicle cargo ships, also known as Fast Sealift Ships (FSS) or SL-7s, are currently the fastest conventional steam powered cargo ships in the world that are still (intermittently) operating, capable of speeds in excess of 33 knots (61 km/h).. Although in reality both are laid up due to their high operating costs and less than green credentials in terms of fuel burned in transporting one unit of cargo per nautical miles traveled. Originally built in 1972 and 1973 as high-speed container ships known as SL-7s for SeaLand, the ships' high operating costs limited their profitability. All eight ships were acquired by the United States Navy in 1981 and 1982, with the last ship converted, delivered to and placed in service with Military Sealift Command in 1986. The conversion entailed the installation of four cranes, addition of roll on/roll off capability and a redesign of the cargo hold to better facilitate storage of vehicles. Due largely to their high cost of operation, all fast sealift ships are kept in Reduced Operating Status, but can be activated and ready to sail in 96 hours. All ships are named after bright stars in the night sky.
MV Shughart (T-AKR-295) is the lead ship of her class of cargo ships operated by the United States Navy. She is a 'roll-on roll-off' non-combat vessel designated as a "Large, Medium-Speed Roll-on/Roll-off" (LMSR) ship.
USNS Comet (T-AK-269), later T-LSV-7, later T-AKR-7, later SS Comet, was a vehicle landing ship built for the United States Navy. The lone ship of her class, she was named for the comet, and was the fourth U.S. Naval vessel to bear the name.
USNS Sea Lift (T-LSV-9) was a roll on/roll off (Ro/Ro) cargo ship built for the United States Navy's Military Sea Transportation Service (MSTS), currently the Military Sealift Command (MSC). She became the first ship of Ro/Ro-type to deliver cargo to Vietnam during the war in Indochina.
USNS GySgt Fred W. Stockham (T-AK-3017) is a Shughart-class container & roll-on roll-off support vessel in the United States Navy's Military Sealift Command (MSC).
