Named for two members of the dolphin family (Delphinidae): Grampus griseus, also known as Risso's dolphin, Orcinus orca or commonly known as the killer whale. Commissioned on May 23, 1941 in the U.S. Navy (USN) under the command of Lt. Commander Edward S. Hutchinson. Afterwards, conducts a shakedown cruise in Long Island Sound.

First War Patrol
On February 8, 1942 departs on her first war patrol and sinks a tanker 8,636 tons, her only kill and performs a reconnaissance of Kwajalein and Wotje. On April 4, 1942 ends the patrol that was deemed as successful.

Second War Patrol
On April 28, 1942 departs on her second war patrol and operates off Truk patrolling off North Pass. While patrolling, spotted an enemy submarine and several patrol vessels. On May 17, 1942 fired on by an unidentified vessel but escaped without damage and survived a three hour depth charge attack that caused only minor repairable damage. On May 30, 1942 fired two torpedoes at a Japanese ship between 3,000 Tons to 5,000 Tons that managed to evaded. On May 25, 1942 spotted another ship but in a rain squall lost the ship. On June 17, 1942 ended the patrol at Fremantle without any results.

Third War Patrol
On July 8, 1942 departs on her third war patrol off the western coast of Mindoro and Luzon including Manila Bay. Although Grampus spotted several ships, the submarine was unable to make successful attacks. On July 18, 1942 fired three torpedoes at a tanker over an hour but no hits were observed. On August 30, 1942 ended the patrol at Fremantle without any results.

Fourth Patrol
Grampus departed on October 2, 1942 for her fourth war patrol with four coastwatchers embarked that were landed on Vella Lavella and Choiseul. During this patrol, she sighted enemy cruisers and destroyers in five different convoys. Although she conducted a series of aggressive attacks against ships, survived the detonation of 104 depth charges. Grampus was not credited with sinking any ships.

On October 18, 1942 targets Yura and fires a spread of four torpedoes, one hits the port side but fails to explode causing only a dent in the hull off Choiseul at Lat 7° 47' S, Long 157° 19' E. On November 23, 1942 ends what is deemed a successful patrol in Australia.

Fifth Patrol
On December 14, 1942 departs on her fifth war patrol in the Cape St. George area. During the patrol, Grampus spots 41 vessels and attacks made on two escorted cargo ships and two transports, a destroyer and a submarine. The submarine survives several depth charge attacks with only minor damage. The submarine claims to damage a cargo ship of 6,000 tons, a transport of 8,000 tons, another transport of 10,000 tons and a destroyer. On January 19, 1943 ends the patrol that was deems as successful.

Sixth Patrol
On February 11, 1943 departs Brisbane on her sixth war patrol with USS Grayback (SS-208) to patrol the central Solomons Islands and failed to return. On March 4, 1943 last seen by USS Grayback (SS-208) as the two submarines were to guard routes out of Kula Gulf to support of U.S. Navy (USN) Task Force 68 (TF 68) shore bombardment of Via on Kolombangara and the brief Battle of Blackett Strait (Battle of Vila–Stanmore).

Sinking History
On March 23, 1943 after repeated attempts to contact Grampus failed, the submarine was presumed lost with all hands. The precise circumstances of her loss remain a mystery but the submarine was likely lost sometime after March 4, 1943 in the central Solomon Islands. Officially struck from the Naval vessel register on June 21, 1943.

There is no specific matching claim for a submarine that could explain the loss of Grampus, but at least two possiblities might relate to the loss of this submarine. On February 18, 1943 Japanese seaplanes from 958 Kokutai (958 Air Group) patrolling in same area Grampus was operating claimed to sink a submarine. Alternately, on March 4, 1943, Grampus was spotted by USS Grayback (SS-208) in her patrol area and thus was not lost before that date. Another possibility is Grampus was lost guarding possible withdrawal routes out of Kula Gulf during the night of March 5, 1943 when Japanese destroyers Minegumo and Murasame were on a supply run to Vila on Kolombangara or in the early morning of March 6, 1943 as a result of the brief Battle of Blackett Strait (Battle of Vila–Stanmore). After the battle, a heavy oil slick was observed that might have been associated with the submarine.
