From Arlington National Cemetery, where the new USS Thresher Memorial was dedicated last week:
A new memorial at Arlington National Cemetery commemorates the service and sacrifice of the crew of the USS Thresher (SSN-593), the world’s most technologically advanced nuclear-powered submarine of its day. On April 10, 1963, Thresher sank during deep-diving tests off the coast of Massachusetts, killing all 129 personnel aboard: 16 officers, 96 enlisted sailors, and 17 civilian technicians. It was the deadliest accident in submarine history, leading the Navy to establish the SUBSAFE Submarine Safety Program.
