US Navy confirms wreckage is that of the submarine USS Grunion lost since WW2

The submarine was reported lost Aug. 16, 1942.  Underwater video footage captured by an expedition hired by sons of the commanding officer, Lt. Cmdr. Mannert L. Abele, allowed the Navy to confirm the discovery.

Japanese anti-submarine attack data recorded no attack in the Aleutian area at the time of the Grunion's disappearance, so the submarine's fate remained an unsolved mystery for more than 60 years, the US Navy said.
