Red Cross, a 123 gross ton steam yacht, was built in 1892 at Providence, Rhode Island. She was renamed Admiral by 1907 and still had that name in July 1917, when the U.S. Navy acquired her. Commissioned as USS Admiral (SP-967), she served on patrol duties in the First Naval District for the rest of 1917 and into the next year. Prior to dawn on 26 March 1918, while en route from Boston to Plymouth, Massachusetts, Admiral struck a rock and gradually sank. Her crewmen were all saved and the ship was soon raised and repaired. She reentered service in August 1918 and continued patrolling along the New England coast through the end of World War I and beyond. USS Admiral was decommissioned in May 1919 and sold in October 1920.
