The USNS Comfort (T-AH-20), pictured here on September 15, 2001, is an example of a United States Naval Ship.

United States Naval Ship or USNS is the prefix designation given to non-commissioned ships that are property of the United States Navy.[1]


United States Naval Ships are usually auxiliary support vessels owned by the U.S. Navy and operated by Military Sealift Command. United States Naval Ships are usually crewed by civilians rather than U.S. Navy personnel, but often times do include a compliment of military personnel..[2] In comparison, U.S. Navy ships commissioned into service have the designation USS and are crewed by U.S. Navy personnel; commissioned and held in property by the United States Government.[3]
