The Mysterious Losses of the USS Thresher and USS Scorpion: The History of the Only American Nuclear Submarines Lost at Sea

In April 1963, one of the most advanced U.S. hunter-killer nuclear submarines and the 129 men onboard vanished while on a routine voyage. The USS Thresher was one of the country’s most advanced ships, but it had the misfortune of becoming the first American nuclear submarine to be lost at sea, prompting obvious questions over what had happened. Had it accidentally collided with a Soviet ship? Was it destroyed by a new and secret Soviet weapon? Was it secretly captured and taken back to the Soviet Union to reveal its secrets?

For those who choose to make the careers as submariners, there is no more beloved service. That is, one hopes, how it was for the 99 men who were serving on the USS Scorpion on May 22, 1968, the fateful day the submarine is believed to have sank. It appears that the crew members died quickly, but however it happened, the grief experienced by their family members dragged on for decades, exacerbated both by the Navy’s lack of information about the submarine’s final moments and the government’s unwillingness to share what little knowledge it had.

It is easy in hindsight to criticize the military for its secrecy, but it must be remembered that the Scorpion disappeared at the height of the Cold War, and therefore, little could be said publicly about its fate. Coincidentally, 3 other nuclear submarines suffered mysterious sinkings the same year, and the Cold War adversaries were interested in locating them and gleaning any secrets or technology that they could from the other side’s bad luck. Indeed, it was only after the fall of the Soviet Union that the truth could be told, bringing closure to family members and a dark lesson in espionage to the American people.
