Upon returning to the United States at the end of 1918, "Wadsworth" underwent a five-month overhaul. She served as a plane guard for the Navy's transatlantic flight attempt by four Navy-Curtiss flying boats in May. After two years in reduced commission in August, "Wadsworth" was reactivated in May 1921. She was decommissioned in June 1922, and spent nearly 14 years in reserve at the Philadelphia Navy Yard. She was struck from the Naval Vessel Register in January 1936, sold in June, and scrapped in August.
