USS Volador (SS-490), a Tench-class submarine, was the second ship of the United States Navy to be named for the volador. The contract to build her was awarded to Portsmouth Naval Shipyard in Kittery, Maine, and her keel was laid down on 15 June 1945, but work on her construction was discontinued in January 1946. Her unfinished hulk remained on the ways until August 1947 when construction resumed, now including GUPPY II enhancements to the basic Tench design. Volador was launched on 21 May 1948 sponsored by Mrs. Dudley W. Morton, and commissioned on 1 October 1948, with Commander H. A. Thompson in command.
