USS Needlefish (SS-493)

USS Needlefish (SS-493), a proposed World War II Tench-class submarine, was the second ship of the United States Navy to be named for the needlefish, a family of voracious elongate teleost fishes resembling, but not related to, the fresh-water gars. Her construction was authorized on 26 January 1945, but the contract for her construction was cancelled on 12 August 1945 before she was laid down in the Portsmouth Navy Yard at Kittery, Maine.
