Somewhere in the North Atlantic, roughly ten thousand feet down, a steel hull sits quietly where it landed nearly six decades ago. No tourist boats circle above it. No permits exist that would let a diver, a scientist, or even a curious billionaire with a private submersible get close. It is one of the most tightly restricted spots on the entire planet, and the reasons behind that restriction are stranger, and more layered, than most people realize.
A Submarine That Vanished Without Warning
In May 1968, the USS Scorpion, a Skipjack class nuclear attack submarine, was making its way back to Norfolk, Virginia after a Mediterranean deployment. USS Scorpion was a Skipjack-class nuclear-powered submarine that served in the United States Navy, and it imploded and sank on May 22, 1968. The crew radioed their position on May 21, expecting to arrive home within days, and then nothing more was heard. The USS Scorpion was a nuclear-powered submarine that sank in May 1968, resulting in the loss of all ninety-nine crew members on board.
The Final Minutes Captured By Underwater Listening Posts
The Navy did not immediately know the submarine was gone. It only became clear something had gone catastrophically wrong when acoustic monitoring stations picked up telltale sounds. There was a single bang, followed 90 seconds later by more underwater rumbles that could only be the fatal sounds of a submarine’s compartments imploding under immense pressure, and it took only three minutes and 12 seconds before all was quiet. A search vessel eventually located the wreckage months later, scattered across the ocean floor far from where anyone expected it to be.
Where The Wreck Actually Rests
The search stretched on for nearly five months before searchers found anything conclusive. After a five-month search, the Navy located the wreckage of the Scorpion in eleven thousand feet of water about four hundred miles southwest of the Azores. The precise coordinates place it at roughly thirty three degrees north, thirty three degrees west, a spot so remote and so deep that recreational access was never realistically possible even before any legal restrictions came into play. The location is often cited as roughly 740 kilometres, or about 400 nautical miles, southwest of the Azores.
Why This Counts As A Legal War Grave
The site is not simply remote, it is formally protected. Under maritime law and long standing U.S. Navy policy, the wreck is treated as a military gravesite because ninety nine sailors died there and their remains were never recovered. Following a maintenance period at Norfolk Naval Shipyard, the Scorpion was deployed to the Mediterranean Sea, and the tragedy left behind sixty four widows and ninety nine children. That grave status alone would be enough to keep casual visitors away, but it is only part of the story.
The Reactor And Torpedoes Still Sitting On The Seafloor
What makes this wreck genuinely different from an ordinary sunken vessel is what it carried. The wreckage of the Scorpion remains in the North Atlantic Ocean with all her armaments and her nuclear reactor. Beyond the reactor itself, the submarine also went down with weapons that most people would not expect a peacetime patrol to be carrying. Scorpion also took its nuclear reactor and two nuclear-tipped MK-45 ASTOR anti-submarine torpedoes to the bottom, and neither the reactor nor the torpedoes were ever recovered.
Decades Of Quiet Radiation Checks
Given what is down there, it would be reasonable to assume the Navy simply forgot about the site after the initial search ended. That is not what happened. The Navy still periodically surveys the Scorpion’s wreck to check for radioactive leakage from her S5W nuclear reactor, and the two ASTOR nuclear-armed torpedoes still residing in her hull. These checks are not occasional curiosities either, they are formalized. The latest publicly available Naval Nuclear Propulsion Program environmental reporting says follow-up sampling near the Scorpion site in 1979, 1986, and 1998 found no evidence of radioactivity released from the reactor fuel elements.
What The Monitoring Has Actually Found
The good news, if there is any in this story, concerns the environmental readings themselves. The 1986 and 1998 sampling campaigns specifically assessed the nuclear torpedoes for plutonium leakage, and measured plutonium levels were consistent with background fallout from weapons testing rather than leakage from Scorpion’s weapons, with the report’s bottom line being that the wreck has had no discernible effect on the radioactivity in the environment. Scientists attribute part of this to how naval reactor materials are engineered. The reactors used in all U.S. naval submarines and surface ships are designed to minimize potential hazards to the environment even under the most severe casualty conditions, with the reactor core physically incapable of exploding like a bomb and fuel elements made of materials that are extremely corrosion resistant, even in seawater.
The Secret Mission Hidden Inside A Famous Discovery
One of the stranger threads in this story involves a name most people associate with a completely different shipwreck. Documents only declassified in December 2018 showed that former U.S. Naval Reserve Commander Dr. Robert Ballard had approached the Navy in 1982 for funding to search for the wreck of the Titanic, and the Navy’s counter proposal was that they would give Ballard the funds only if he first surveyed the wreck sites of the Thresher and the Scorpion and assessed the radioactive threat. Ballard completed that classified assignment before turning his equipment toward the Titanic, a fact the public did not learn for decades. His obligation to inspect the wrecks completed, and with the radioactive threat from both established as small, Ballard then searched for Titanic, and the debris-field search technique he had used for the two submarines was successfully applied to locate Titanic.
A Mystery The Navy Still Cannot Fully Explain
Despite all the monitoring and all the technology brought to bear over the years, one basic question has never been settled. What actually caused Scorpion to sink remains officially unresolved. Only USS Scorpion’s reason for sinking is unknown, and the results of the U.S. Navy’s various investigations into the loss of Scorpion are inconclusive. Families and veterans groups have pushed for a fresh look at the case more than once. In November 2012, the U.S. Submarine Veterans, an organization with over 13,800 members, asked the U.S. Navy to reopen the investigation on the sinking of USS Scorpion, and the Navy rejected the request.
The Debate Continues Into 2025 And Beyond
Even now, new arguments about what really happened keep surfacing in naval history circles. In a 2025 Naval History article, author Ed Offley argued that the familiar Scorpion narrative leaves out too much of the internal Navy record, and his reading of declassified Court of Inquiry material points to a possible large charge weight external to the pressure hull. That theory has not been embraced by the Navy or by most specialists in the field. It has been pushed back on by other submarine and naval-history specialists, and is not the Navy’s adopted public conclusion.
The Scorpion sits in a strange category of its own: a war grave, a nuclear hazard site, and an unsolved mystery, all at once, hundreds of miles from the nearest coastline. It will likely stay exactly where it is, monitored quietly and visited by no one, for as long as anyone is keeping records. Some places on Earth remain closed not because of a single rule, but because history, law, and physics all happen to agree on the same answer.
