USS Conger (SS/AGSS-477), a Tench-class submarine, was the only ship of the United States Navy to be named for the conger, an eel found in warm seas at moderate depths, common to both coasts of the Atlantic Ocean. Her keel was laid down on 11 July 1944 by the Portsmouth Naval Shipyard. She was launched on 17 October 1944 sponsored by Mrs. W. C. Ploeser, and commissioned on 14 February 1945 with Lieutenant Commander H. D. Sipple in command.
