The Groundbreaking Submarine That The United States Navy Is About To Unveil

First Patrol

That’s when things started to become very bad. After completing her first wartime cruise from February 15 to April 10, 1942, the submarine returned to Pearl Harbor. There, on the morning of February 22, an enemy submarine launched two torpedoes at Grayback, which the submarine then pursued across the Pacific. The battle lasted four days. Once, the Japanese ship approached the position of Grayback, but the submarine was unable to get in position to engage.
