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.

Continuing patrol duty off Connecticut, throughout the war, Navajo decommissioned and was sold 1 November 1919.
