The U.S. Navy inspected her in July 1918 for possible naval service and purchased her on 19 July 1918 from R. K. Snow for use as a section patrol boat during World War I. She was commissioned the same day at Norfolk, Virginia, as USS Helvetia (SP-3096). The Navy sold Helvetia back to R. K. Snow in February 1919.
