into World War II, Semmes added escort missions, training services for the Key West Sound School, and antisubmarine patrol work to her duties. At Key West from 16 March-16 April 1942, she performed escort and patrol work off the mid-Atlantic seaboard into May; and, on the morning of the 6th, while patrolling off Cape Lookout, collided with a British armed trawler, Senateur Duhamel. The latter sank; and, after assisting the survivors, Semmes put into Morehead City, North Carolina, for temporary repairs. Permanent repairs were completed at Norfolk on 3 June and the former destroyer resumed her test and evaluation, patrol, and escort work which she continued through the end of the war in Europe. After the capitulation of Germany, Semmes resumed her primary mission of testing experimental equipment and, for the remainder of her career, conducted tests for the Underwater Sound Laboratory, New London, Connecticut, as a unit of the antisubmarine surface group of the Operational Development Force. Other duties during that period included the provision of training services to the Submarine School and to the Fleet Sonar School. Semmes can be seen briefly as AG-24 in the 1943 movie Crash Dive, filmed at the Submarine Base New London. Fate On 21 May 1946, Semmes again entered the Philadelphia Navy Yard for inactivation. Decommissioned on 2 June, her name was struck from the Navy list on 3 July; and her hulk was sold for scrapping to the Northern Metals Corporation, Philadelphia on 25 November. She was scrapped the following year. Awards Semmes received five battle stars for service in World War II.
