Wow, quite a rarity to find a MIA WW2 sub, and for good reason - There are battleships and carriers still MIA in the vast expanses and depth of the pacific, it would take quite a bit of effort, research, resources and luck to find a sub.
They even managed to photograph a legible nameplate with a ROV to quickly confirm the subs identity.



The last resting place of WW2 submarine the USS Grayback is found off the coast of Okinawa using high-tech undersea drones 75 years after the Japanese dropped a 500 pound bomb on it sending it 1,400ft down

The missing WWII submarine the U.S.S Grayback was found in June after the ship mysteriously disappeared 75 years ago off of Japan
It was presumed lost, along with 80 American servicemen, in March 1944
The Grayback sank more than a dozen ships during the war
Researchers with Lost 52 Project are dedicated to finding the final resting places of the 52 U.S. submarines lost in action during WWII
They combed Japanese military records which said their planes dropped a 500-pound bomb on the Grayback 100 miles east-southeast of Okinawa
This year a Japanese researcher reviewed those records and found one digit of the Grayback's final coordinates was mistranslated
The real location of the Grayback was about 100 miles off and the sub discovered 1,427 feet deep and 50 nautical miles south of Okinawa
