A U.S. Navy submarine missing for 75 years has been found off Okinawa, Japan. The USS Grayback was discovered in June, according to the Lost 52 Project, a group of undersea explorers whose mission is to find the wrecks of every American submarine lost in World War II.
The Grayback sailed out of Pearl Harbor on January 28th, 1944, for its 10th combat patrol. Two months later, it was listed as missing and presumed lost.
