USNS Provo (T-AG-173) was a Phoenix-class miscellaneous auxiliary acquired by the United States Navy in 1962, crewed by a civilian crew from the Military Sea Transportation Service, and sent to the Philippines to serve as a delivery ship of parts and supplies to other Navy ships and stations in the Asian area.

Provo, a special projects ship, was laid down 28 April 1945; launched 17 June 1945 by Oregon Shipbuilding Corporation, Portland, Oregon; sponsored by Miss Anna P. Burkhalter; and delivered as SS Drew Victory 14 July 1945 and operated by the Weyerhaeuser Steamship Company.

On 2 March 1963, she was acquired by the Military Sea Transportation Service (MSTS) from the U.S. Maritime Administration, and renamed Provo, 20 November 1962, with the designation of Special Project Ship (AG–173).

In July 1963, she and two other MSTS ships, Cheyenne and Phoenix, were stationed at Subic Bay, Philippines, as Forward Floating Depots.

This mission concept involved the use of depot ships for floating storage and issuance of vital military materials in meeting contingencies.
