Over sixty years after the sub went missing, an expedition hired by the sons of the commanding officer, Lt. Cmdr. Mannert L. Abele, found the sub.
Abele's sons, Bruce, Brad, and John, began working on a plan to find the sub after finding information on the Internet in 2002 that helped pinpoint USS Grunion's possible location.
In August 2006, a team of side scan sonar experts hired by the brothers located a target near Kiska almost a mile below the ocean's surface. A second expedition in August 2007 using a high definition camera on a remotely operated vehicle yielded video footage and high resolution photos of the wreckage.
