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 Henry J. Kaiser class is an American class of eighteen fleet replenishment oilers which began construction in August 1984.

One ship, operated by the United States from 1987 to 1996, was sold to Chile in 2009 and commissioned into the Chilean Navy in 2010; and two ships were scrapped in 2011 while still incomplete.

The Naval Fleet Auxiliary Force is a division of the US Navy. The 42 ships of the Military Sealift Command's Naval Fleet Auxiliary Force are the supply lines to U.S. Navy ships at sea. These ships provide virtually everything that Navy ships need, including fuel, food, ordnance, spare parts, mail and other supplies. NFAF ships enable the Navy fleet to remain at sea, on station and combat ready for extended periods of time. NFAF ships also conduct towing, rescue and salvage operations or serve as floating medical facilities. All NFAF ships are government owned and crewed by civil service mariners. Some of the ships also have a small contingent of Navy personnel aboard for operations support, supply coordination and helicopter operations.
