USS Thresher (SSN-593)
The second USS Thresher was the lead boat of her class of nuclear-powered attack submarines in the United States Navy. However, disaster struck on April 10, 1963. Thresher sank during deep-diving tests about 220 miles east of Boston, Massachusetts. As a result, all 129 crew members were killed in the deadliest disaster ever. Following this loss, the U.S. Navy implemented a rigorous submarine safety program named SUBSAFE.
