''Grunion'' was launched by the Electric Boat Co., Groton, Conn., 22 December 1941; sponsored by Mrs. Stanford C. Hooper, wife of Rear Admiral Hooper; and commissioned 11 April 1942, Lt. Comdr. M. L. Abele in command.

Departing Hawaii 30 June after 10 days of intensive training, ''Grunion'' touched Midway; then headed toward the Aleutians for her first war patrol. Her first report, made as she patrolled north of Kiska Island, stated she had been attacked by a Japanese destroyer and had fired at him with inconclusive results. She operated off Kiska throughout July and sank two enemy patrol boats while in search for enemy shipping. On 30 July the submarine reported intensive antisubmarine activity; and she was ordered back to Dutch Harbor.

''Grunion'' was never heard from nor seen again. Air searches off Kiska were fruitless; and on 5 October ''Grunion'' was reluctantly reported overdue from patrol and assumed lost with all hands. Captured Japanese records show no antisubmarine attacks in the Kiska area, and the fate of ''Grunion'' remains a mystery. Her name was struck from the Navy List 2 November 1942.

After the war, captured Japanese records showed no antisubmarine attacks in the Kiska area, and the fate of ''Grunion'' remained a mystery until 2002, when the Abele brothers, sons of the ''Grunion's'' commanding officer, were placed in touch with a Japanese naval buff, who provided them with information that the sub was engaged in battle with an armed freighter. This enabled the brothers to put together a team of international searchers resulting in the discovery of the sub off Kiska in 2006, and her positive identification by the Navy two years later.
