USS Key (DE-348) was a John C. Butler-class destroyer escort acquired by the U.S. Navy during World War II. The primary purpose of the destroyer escort was to escort and protect ships in convoy, in addition to other tasks as assigned, such as patrol or radar picket. Post-war, she returned home proudly with one battle star to her credit. Key was launched 12 February 1944 by Consolidated Steel Corp., Orange, Texas, sponsored by Mrs. Ira F. Key, mother of Lt. Key; and commissioned 5 June 1944, Lt. Comdr. F. D. Buckley in command.
