The Navy has recently confirmed that the wreckage found off the coast of Alaska is a missing WWII submarine, the USS Grunion. The sub sank on July 30th, 1942, and was recently discovered by the sons of the Grunion’s Commander Mannert Abele, who found the wreckage in August 2007. Why it took over a year for the Navy to confirm the sub’s identity is not clear.

Also a mystery is why exactly the Grunion sank in the first place. It currently rests over 3,200 feet below the surface, and no one feels like moving it anytime soon.

The Michigan soldiers that died on the Grunion:

Seaman 2C Arnold Post, 18, of Midland
Torpedo's Mate 3C Richard McCutcheon, 18, of Detroit
Seaman 2C David Nathaniel Swartwood, 19, of Flint;
Seaman 2C Byron Traviss, 17, of Detroit
Seaman 2C Loyal Ryan Jr., 17, of Lansing
Ensign William Cuthbertson Jr., 27, of Frankenmuth

Over 70 men perished when the USS Grunion sank. 

Yes, I know the picture I used is a German U-boat you history nerds.
