United States Naval Ship (USNS) is the prefix designation given to non-commissioned ships that are property of the United States Navy (USN). [1]
United States Naval Ships are unarmed auxiliary support vessels owned by the U.S. Navy and operated in non-commissioned service by Military Sealift Command with a civilian crew. Some ships include a small military complement to carry out communication and special mission functions, or for force protection. [2]
In comparison, U.S. Navy ships commissioned into service have the designation "USS" and are armed, crewed by U.S. Navy personnel, and held in property by the United States Government. [3] Additionally, the United States Naval Ships hull classification symbol begins with "T-" to denote its civilian crew. The USNS prefix can be assigned only while the ship is owned by the U.S. Navy. If, after being taken out of service, the ship is transferred to the Maritime Administration the prefix reverts to a civilian ship prefix such as the case of SS Comet.
A ship prefix is a combination of letters, usually, abbreviations, used in front of the name of a civilian or naval ship that has historically served numerous purposes, such as identifying the vessel's mode of propulsion, purpose, or ownership/nationality. In the modern environment, prefixes are cited inconsistently in civilian service, whereas in government service a vessel's prefix is seldom omitted due to government regulations dictating that a certain prefix be used. Today the common practice is to use a single prefix for all warships of a nation's navy, and other prefixes for auxiliaries and ships of allied services, such as coast guards. For example, the modern navy of Japan adopts the prefix "JS" – Japanese Ship. However, not all navies use prefixes; this includes the significant navies of China and Russia. France and Spain do not use ship prefixes as such, but use NATO designations FS and SPS if needed.
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.
United States Ship is a ship prefix used to identify a commissioned ship of the United States Navy and applies to a ship only while it is in commission. Before commissioning, the vessel may be referred to as a "pre-commissioning unit" (PCU), but is officially referred to by name with no prefix. After decommissioning, it is referred to by name with no prefix, though people commonly refer to those ships with the prefix "ex-", as in ex-ship name. In-service but non-commissioned Navy ships go by the prefix USNS, which stands for United States Naval Ship.
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.
USNS Yukon (T-AO-202) is a Henry J. Kaiser-class underway replenishment oiler operated by the Military Sealift Command to support ships of the United States Navy.
The jack of the United States, known as the Union Jack, is a maritime flag representing U.S. nationality, flown on the jackstaff in the bow of U.S. vessels that are moored or anchored. The U.S. Navy is a prime user of jacks for its warships and auxiliaries, but they are also used by non-naval vessels such as ships of the U.S. Coast Guard, the predominantly civilian-crewed replenishment and support ships of the U.S. Navy's Military Sealift Command, the ships of the National Oceanic and Atmospheric Administration, and other U.S. governmental entities. The jack is flown on the bow (front) of a ship and the ensign is flown on the stern (rear) of a ship when anchored or moored. Once under way, the ensign is flown from the main mast and the jack is lowered, removed, and stowed away for future use.

On 1 April 1968 Observation Island was redesignated as a miscellaneous auxiliary USS Observation Island (AG-154). Observation Island was decommissioned and placed in reserve from 1972 until 1977 in the Suisun Bay Reserve Fleet until withdrawn and then returned in 1978.

USNS Sgt. Joseph E. Muller was a C1-M-AV1 cargo ship completed 9 June 1945 and delivered to the War Shipping Administration (WSA) as Check Knot. After operation by WSA's agent Waterman Steamship Company June 1945 – November 1946 and being placed in reserve the ship was transferred to the U.S. Army and renamed USAT Sgt. Joseph E. Muller. She was transferred to the United States Navy in 1950 after the establishment of the Military Sea Transportation Service under Navy and assigned to Korean War supply and transport operations. She was again place back in service in 1962 as one of the civilian crewed, Auxiliary General (AG), technical research ships working on National Security Agency/Naval Security Group missions, based out of Florida. She was finally declared surplus to needs in 1969 and struck.

The mine blew a hole in the hull. In order to save the ship the Skipper ran it aground in Da Nang harbor. The USS Navy standby salvage ship USS Grasp with its crew of divers installed a box patch over the hole and pumped the water from the bilges, before moving the ship to a pier. US Army tanks hung from ship booms to heel the ship so that a metal patch could be welded in place to return the ship to duty. SS Transcolorado, she was chartered by the Military Sealift Command as a civilian cargo ship designated T-AK-2005.
