Some of the descriptions of the lost ship sound more like the Thresher than the Scorpion The scorpion was actually spying on Soviet subs, not just training. My theory on her loss is based on certain facts: 1. They had noted a recurring problem with noxious Freon leaks. 2. The running light covers were open as if she had been on the surface. 3. She was going backward when she disappeared. Therefore, I believe that she had to surface for air after a Freon leak, and upon reaching the surface encountered a ship of some kind, and backed up to try to avoid a collision, but to no avail. And the ship's crew, not wanting to cause an international incident between the super-powers, decided not to go public about the accident.

If a torpedo blew up the bow would have been destroyed. When Ballard visited the Scorpion in 87, the battery well access hatch from lower level ops was recovered. Fragments of the battery was found embedded in the hatch. Scorpion was lost due to an explosion in the battery well. The nave light: On Scamp, the housing for the light was loose. We lashed it shut with rope prior to diving.

It has been determined "by long term expert analysis" that the Scorpion suffered two hydrogen explosions in her battery compartment beneath the bottom deck plates at the bottom of the Operations compartment in the bunking area. My Bunk was right above the deck and I slept just above the Battery Compartment. These two explosions were 0.5 seconds apart and had the explosive potential of 20 pounds of TNT Each. These explosions completely destroyed the Operations Compartment. This would lead to an out of Control decent through test depth and to an implosion. You can find the official report here: www.burtonsys.com/USS_Scorpion.html
BTW, I was assigned to the Scorpion's sister ship the USS Scamp SSN 588 for 4 years.

Initial event was an internal explosion in the Torpedo Room caused by a low yield detonation of a skid mounted torpedo. The cause of the detonation may never be known. The force of the explosion (over pressure) resulted in both the escape trunk personnel hatch and the torpedo loading hatch being blown open and detached from their hinges. Pictures of the wreck clearly show the detachment. Recent reanalysis of the sounds recorded at the time of the sinking, indicate the blown hatches to have occurred .5 seconds apart. The Torpedo Room flooded quite rapidly and the forward main ballast tank blow system may have failed due to the explosion. The resulting down angle prevented the ship from surfacing in the forward direction. Most likely, the crew tried to back the ship to the surface.
This may have been successful but a severe down angle still would have been present causing the propeller to repeatedly break the surface and submerge. This then resulted in stress to the propeller shaft causing it to break within the pressure hull, extruding through the seal mechanism and flooding the Engine Room. Flooding of the Engine Room would have been complete by the time the ship had descended to crush depth.
The hull collapse of the Auxiliary Machine Space resulted from the pressure on the Engine Room bulkhead and the pressure hull exterior stress of the AMR. This then caused the 'telescoping' of the Engine Room into the spaces forward of it. This then resulted in the rapid flooding, atmosphere pressurization and breach of the fuel oil tanks within the Operations Compartment. The resulting explosion caused the ship to break in two at the forward end of this compartment. The sequence of events stated here are the result of extensive review of the wreck site photos. Many who have speculated on the cause of the sinking have never reviewed the photos and may never have set foot in a submarine. I was qualified in submarines and crewed aboard one for 7 years, I know what I'm talking about.

Walt is incorrect, The Scorpions operating depth was limited by Sublant to 500 ft (not deep). Reactor Scrams do not cause a ship to sink, negative buoyancy does. The ship would not have scramed the reactor. that is pure speculation. The only people who know the exact reason, are those brave men who gave their life aboard that ship. May they rest in peace.

USS Scorpion sank not in the Triangle but across the Atlantic off the Azores. Sub was deep and doing training, they scrammed the reactor and could not get passive measures re-balanced and slipped backwards down past crush depth and imploded, the site is currently monitored for radio active leakage, none so far.
