Built for War
The design of the Grayback had ten 21-inch torpedo tubes (six towards the bow and four at the stern), thus making her well-equipped. The submarine also boasted a 50-caliber gun, Oerlikon 20mm cannons, and Bofors 40mm and was all mounted on the deck. The weapons were installed to provide some level of defense against rivals and enemy warships that would approach when the sub surfaced. Her crew did not know what kind of dangers they would face, but they put faith in their defenses.
Commissioned for War
Ten months after being constructed by the Electric Boat Company, Rear Admiral Wilson Brown’s wife launched the Grayback on January 31, 1941. She was later commissioned into the U.S. Navy on June 30, just about five months before America was back at war with the Japanese who had launched an attack on Pearl Harbor. America was gearing itself up for battle, consolidating its greater fleet for total and ambitious war.
