USNS Navajo (T-ATF-169) is a United States Navy Powhatan-class fleet ocean tug in service since 1980.

Navajo was laid down on 14 December 1977 by the Marinette Marine Corporation at Marinette, Wisconsin. Launched on 20 December 1979, and delivered to the U.S. Navy on 13 June 1980, Navajo was assigned to the Military Sealift Command (MSC), and placed in non-commissioned service as USNS Navajo (T-ATF-169) in 1980.

Lost anchor incident[edit]

On 28 July 2012 the ship was conducting training near the entrance to Pearl Harbor, Hawaii when a parted mooring line caused the ship to dump 8,000 pounds of anchor, chain, and heavy rope on the ocean floor 150 feet below. The equipment was recovered on 9 August 2012.[1]

Navajo remains in active service.
