    Dictionary of American Naval Fighting Ships: Navajo III, a motorboat built by Gas Engine & Power Co., and Chas. L. Seabury, Morris Heights, N.Y., was acquired by the Navy from Arthur Clapp 25 June 1917 and commissioned the same day at the Brooklyn Navy Yard, Chief Boatswain's Mate Samuel J. Willis in command.

    Operating in the 3d Naval District, New York during World War I, Navajo III steamed to Fort LaFayette 27 June and thence to New Haven to patrol the submarine net zone of Long Island Sound. Navajo was towed up Quinnipiae River by Abaloma (SP-208) 5 August, thereafter operating around Coinfield with SP-46, SP-12, and SP-100. After steaming to Smithtown Bay for target practice in November, she proceeded to Marme Basin, remaining there until April 1918.

    In 1918, Navajo was attached to Squadron 6, headquartered at Bridgeport, Connecticut, and patrolled the entrance to Bridgeport harbor, shifting to patrol between Pinfield Reef and Stratford Shoal in June. Continuing patrol duty off Connecticut, throughout the war, Navajo decommissioned and was sold 1 November 1919.
