Tillamook was laid down on 6 January 1914 by the Seattle Construction and Dry Dock Company at Seattle, Washington and launched on 15 August 1914. She was placed in service soon thereafter, probably later in August or in September 1914, as USS Tillamook (Tug No. 16).

Tillamook steamed south to San Francisco, California, and reported to the Commandant, 12th Naval District, for duty at Mare Island Navy Yard in Vallejo, California. She served her entire 33-year U.S. Navy career towing and assisting ships at Mare Island Navy Yard.

During her service, Tillamook changed designations three times. On 17 July 1920, when the Navy adopted the modern system of alpha-numeric hull designations, she was classified as a fleet tug and redesignated AT-16. On 31 January 1936, a number of old tugs previously classified as fleet tugs were reclassified as harbor tugs, and Tillamook became a harbor tug designated YT-122. She received her final classification, as a medium harbor tug, on 13 April 1944 and was redesignated YTM-122.

Tillamook was placed out of service and turned over to the Maritime Commission for disposal on 28 April 1947.
