USNS Powhatan (T-ATF-166)

USNS Powhatan (T-ATF-166) was a United States Navy Powhatan-class fleet ocean tug in service from 1979 to 1999.

Powhatan was laid down on 30 September 1976 by the Marinette Marine Corporation at Marinette, Wisconsin. Launched on 24 June 1978, and delivered to the U.S. Navy on 15 June 1979, Powhatan was assigned to the Military Sealift Command (MSC), and placed in non-commissioned service as USNS Powhatan (T-ATF-166) in 1979.

Powhatan was taken out of service on 26 February 1999 and leased to Donjon Marine Company, Inc., of Hillside, New Jersey, for commercial service, subject to recall by the Navy.

Upon completion of the lease, Powhatan was struck from the Naval Vessel Register on 25 February 2008 and sold to Turkey on 26 February 2008 through the Security Assistance Program. Due to her poor condition upon termination of the lease, she underwent a refit which included complete rebuilding of all engines and generators at Charleston, South Carolina. During the refit, the ex-Powhatan was commissioned into the Turkish Navy as TCG Inebolu (A-590).
