"USS Grampus (SS-207), a Tambor-class submarine, was the sixth ship of the United States Navy to be named for a member of the dolphin family (Delphinidae): Grampus griseus, also known as Risso's dolphin.
Her keel was laid down by the Electric Boat Company of Groton, Connecticut. She was launched on 23 December 1940 (sponsored by Mrs. Clark H. Woodward) and commissioned on 23 May 1941 at New London, Connecticut, with Lieutenant Commander Edward S. Hutchinson in command. Grampus received three battle stars for World War II service. Her first, fourth, and fifth war patrols were designated successful...
Sinking
In company with Grayback, Grampus departed Brisbane on 11 February 1943, for her sixth war patrol from which she failed to return; the manner of her loss still remains a mystery. Japanese seaplanes reported sinking a submarine on 18 February in Grampus' patrol area, but Grayback reported seeing Grampus in that same area 4 March. On 5 March 1943, the Japanese destroyers Minegumo and Murasame conducted an attack preceding the Battle of Blackett Strait, near Kolombangara island. A heavy oil slick was sighted there the following day, indicating that Grampus may have been lost there in a night attack or gun battle against the destroyers. The Japanese destroyers had by then already been sunk in a night action with U.S. cruisers and destroyers.
When repeated attempts failed to contact Grampus, the submarine was declared missing and presumed lost with all hands. Her name was struck from the Naval Vessel Register on 21 June 1943."
