USS Cubera (SS-347), a Balao-class submarine, was a ship of the United States Navy named for the cubera, a large fish of the snapper family found in the West Indies. Cubera (SS-347) was launched 17 June 1945 by Electric Boat Co., Groton, Conn.; sponsored by Mrs. J. Taber; commissioned 19 December 1945, Lieutenant Commander R. W. Paine, Jr., in command; and reported to the Atlantic Fleet. Cubera appeared in Ray Harryhausen's It Came from Beneath the Sea (1955), playing an "atomic sub" used to dispatch the film's giant octopus.
