Bow of WWII sub found near Aleutian Islands

The USS Grunion went missing about a month after it departed on its first war patrol in 1942. It wasn't seen again until the sons of the Grunion's commanding officer began searching for it and found the wreckage in 2007 off the coast of the Aleutian Islands.

Missing sub reported short-circuited battery

The Argentine military Tuesday released its most detailed timeline yet in this month's disappearance of a naval submarine, saying that the vessel first reported a battery short-circuit roughly 10 hours before an explosion-like sound was detected near the sub's last known location.
