She was commissioned as USS Green Dragon (SP-742) in 1917.

Assigned to the 2nd Naval District in southern New England, Green Dragon patrolled the coast of the United States from Chatham, Massachusetts, to New London, Connecticut, for the rest of World War I.

Green Dragon was sold to George E. Clement & Son of Philadelphia, Pennsylvania, on 25 February 1922.
