'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.
As a result of a 2012 reorganization, Naval Fleet Auxiliary Force was renamed Combat Logistics Force, with some of its ship categories being transferred to a new Service Support program.
Fleet Replenishment Oilers

These ships are especially valuable because of their speed and ability to carry all the essentials to replenish Navy ships at sea. MSC's fast combat support ships, formerly sailor-operated, transferred to MSC for civil service crewing beginning in 2001.

Designed to operate for extended periods at sea, the ''Lewis and Clark''-class ships have improved cargo handling equipment that increases efficiency and makes the ships more cost effective to operate and maintain. All of the ''Lewis and Clark''-class ships are named after great American pioneers. These ships are listed as follows:

Fleet Ocean Tugs
The Military Sealift Command's fleet ocean tugs provide the Navy fleet with towing service and can tow Navy vessels as large as battleships. When augmented by Navy divers, fleet ocean tugs assist in the recovery of downed ships and aircraft. In addition, when carrying specialized equipment, the fleet ocean tugs can also perform submarine rescue operations. The Auxiliary fleet's tugs are:

These ships, like fleet ocean tugs, are able to lift objects as heavy as downed ships and aircraft.

The ships are normally kept pierside in reduced operating status, each with a small contingent of MSC civil service mariners and Navy hospital personnel aboard to ensure the ships are ready should they be needed. When called into action, they can get underway in five days with an expanded crew of more than 60 civil service mariners and an expanded medical staff of up to approximately 1,200 military medical personnel. The Auxiliary Fleet's hospital ships are the:
