USS Scorpion and USS Thresher Wreckage

[@gw5309]

I worked with a guy who's brother was on the Scorpion crew, but became ill and wound up hospitalized and missed her ill-fated departure. The fact that he was replaced by someone who was not a regular part of the crew always haunted him.

I'm an old Sturgeon class submariner during the 1980s and 1990s. When I volunteered for submarine duty, I had never heard of the Thresher or Scorpion. During my service years, I learned alot about each catastrophe. I thought of those lost sailors many times as I was poking holes in the ocean. I still think of them long after my submarine days are over.

That voice in the second half of the video you hear talking about "Alvin" is Dr. Robert Ballard, who found the Titanic on the same mission. Believe it or not, Dr. Ballard was a captain in the US Navy Reserves, and his cover story to find the Titanic was given to him so he could photograph the Scorpion, who's location is still classified so that the Soviets couldn't snoop around it.He used the same technology he used a few days later to find the Titanic to photograph and map the Scorpion's wreck for the Navy, they then told him to use his remaining days after he fulfilled his mission to look or the Titanic to complete the cover story...and he ended up actually finding it.

[@LindaTCornwall]

Interesting, only trouble is Wikipedia gives the location lol.. it states: Located on the seabed of the Atlantic Ocean, 32°55′N 33°09′W,[2] in 3,000 m (9,800 ft) of water, 740 km (400 nmi) southwest of the Azores. Interestingly though, Titanic's location isn't listed as it's a protected site.

I was stationed in Rota, Spain, on the USS Canopus, AS34 at the time the Scorpion arrived. As a member of a refit division, I was ordered to obtain specific information from our technical library. After that I was able to chat with a few of the sailors standing topside on the Scorpion. Following the Scorpion's departure, we learned of her being lost. Our refit shop was stunned and remained gloomy for some time.

[@floydhawk2169]

I too was on the Canopus at that very time, one of the Scorpion's crew was assigned to my shop temporarily due to a positive TB test. He therefore missed his boat when it left and was saved. Ironically a second TB test was negative. Don't recall his name but he was a PO1.

[@PRR5406]

I think it's pretty well understood that when the internal explosion holed "Scorpion", the following implosion at depth was instantaneous, and the crew knew only of a "situation being handled". "Thresher's" crew, terribly, had to wait and listen to their ship to fail, while they helplessly tried to remedy an impossible situation of physics.

[@derekwall200]

exactly what happens inside a 270ft nuclear powered fast attack sub like this when the hull implodes? doesn't the water compress an air pocket in any compartment in the sub to the point where it just explodes violently?

[@PRR5406]

derek wall It's a steel bubble that compresses on all sides equally, much like a Diesel cylinder. Under those forces, I would imagine the air temperature raises instantaneously, but there is insufficient temperature to cause ignition of substances. The bubble escapes the steel sherds and races to the surface, while the flooded steel hull and what's left inside it, falls to the ocean bed. It's a violent, but mercifully quick death.

[@derekwall200]

PRR5406 quick but violent from the way it sounds. but either way it would suck to die trapped inside a steel coffin only to end up 9000ft down on the ocean floor. but I suppose the worst way to die would be a radiation leak from her nuclear reactor.

[@redwoodcoastcalif]

Awesome footage; thanks for uploading. I qualified on USS Bergall (SSN-667) in 1980. We did a DSRV mother-sub op in Aug 1978 with DSRV-1 Mystic; and later I served aboard DSV Turtle (DSV-3). We had several visits with DSV Alvin crewmembers when Atlantis II came to operate in the Pacific. The loss of Thresher and Scorpion were always close aboard; we were taught Rickover's zero tolerance for error mindset from the moment I stepped into Sub School, to the day I retired in Sept 1998. This footage incredible, and should be used at the conclusion of Tolling the Lost Boats ceremony.

[@mcrunnin1737]

The author of The book “blind mans bluff” goes deep into detail and in my mind correctly concludes that the cause of the scorpions demise was from torpedo battery fire leading to low yield explosion, therefore blowing the hatches in the torpedo room, but rupturing the pressure hull. Dr Craven did extensive research on this theory and it has the most likely explanation in my opinion

[@OneLastHitB4IGo]

[@andrewtaylor940]

The book was amazing. A must read if you are a fan of Subs.

[@tuber00009]

Reading now. It's a fascinating account!

[@andrewtaylor940]

The theory on Scorpion was it was a “hot run” on a torpedo. It’s a little more complicated than a battery fire. Torpedo’s aren’t bombs. They are complex self piloting underwater vehicles with a warhead. What this means is they require maintenance and inspection and testing on a regular basis. But there was a known but largely covered up issue with the torpedo’s Scorpion was carrying. On occasion when connecting the test leads to the batteries during maintenance, a hot run would occur. The torpedo would trigger as if fired, start spinning and arm itself. And once it reached what it calculated to be its set distance, explode. Since the room around it would trigger its proximity sensors. Once this started the only way to stop it was to spin the torpedo 180 degrees so it’s safety sensors would kick in. The torpedo’s had a safety system to shut them down if they turned 180 and started heading towards their own boat. Typically the fastest way to spin the torpedo the needed 180 degrees was to do a hard turn to spin the entire sub onto a reverse heading. But they would only have a minute to do this. Assuming it worked. Part of the evidence for this theory is Scorpion should have been heading West across the Atlantic towards Norfolk. And last known contacts had her traveling West. But when found Ballard found her she was pointed East. The assumption being she had swung East to try and shut down a hot torpedo. Which was the trained response.

Thresher was on a post refit, test-depth dive and was not armed with any undersea weapons at the time of her loss with all hands and civilian personnel. USS Scorpion, lost five years later, was carrying two ASTOR (anti-submarine torpedoes) at the time it was lost while on operational patrol. My name is Stephen Johnson and I'm the author of "Silent Steel: The Mysterious Death of the Nuclear Attack Sub USS Scorpion". My book is the only nonfiction book on the subject

[@coastalsteve]

Stephen - I am currently half way through your book, and I want to say that I am deeply moved by what I have read so far. I have been hesitant to read any sensationalized accounts of either the loss of the Thresher or the Scorpion, but your book was praised in several sub groups I belong to. As a Navy submariner who served on two boomers and one fast boat from 1978 until 1984, and who was the M-Div Sub Safe Petty Officer for the fast boat, I am appalled at the description of the poor maintenance practices and attitudes of the upper chain of command towards the fast boats in the 60's. My heart goes out to my lost brothers on both boats and their families. I spent some time in PSNY, where mention of the Thresher was not a welcome topic. Submarines are beautiful, complex, and dangerous machines; I would not trade my experience for any other. Thank you for the respect I feel that you have shown this subject.

Growing up in Annapolis, much of the time on the campus of the US Naval Academy, in the mid-late 60's I frequently saw submarines docked or moored at the now-David Taylor Naval Ship Research & Development Center at the mouth of the Severn River directly across from the Academy. I wanted so much to get near them. My grandfather took me out fishing on the Chesapeake on weekends. One of those days, the USS Scorpion was at anchor in the Severn. He circled for what seemed an hour...... I will never forget watching the submariners on deck, thinking of the enormous contrast in their two worlds. I will also never forget it was very shortly thereafter I learned of the terrible plight. My friends' father was a lead investigator on the USS Thresher forensics, but it'd be a very long time until anything about the USS Scorpion would become public.

I was on the USS Michigan SSBN 727. I remember learning about the Thresher. It was a failed EMBT blow, hi-pressure air somehow had moisture in them (was 4500 psi on our boat). They were on sea trials, angles and dangles, then an emergency surface from what I heard.

Silver brazed joints versus welded on the valves...

[@billofjazz]

I qualified on the USS Dace (SSN 607), the sister ship that replaced the Thresher in SUBDEVGRU 2 in the Groton sub base. The high-pressure air tanks that are located outside of the pressure hull stored HP air at 4500 psi. When the boat blows MBTs to the surface, the HP air was routed through reducers that sent the air to the ballast tanks at 3,000 psi. The Sturgeon class (I rode the Queenfish) sub-safe engineering included an emergency blow system that ported 4500 psi air directly from the storage banks directly into the MBTs. I'm sure all subsequent sub designs included that very design. As Chief of the Watch aboard the USS Ethan Allen, I got to stand up to reach the valves that ported air to the emergency blow system. Oh, what a ride.

Thresher (SSN-593) "That analysis also determined the Thresher non-vital electrical bus, after two minutes of line-frequency instability, failed for unknown reasons at 0911R while the nuclear reactor coolant pumps (RCPs) were in FAST. (Note: the SSTGs were not acoustically detected; the instability of the non-vital bus was derived from measured instability in the RCP rotational-rates. The non-vital bus line frequency was determined by correcting for the 2.5 percent slip of the RCP drive motors. Also note that the signal strength of the RCP sources at 0911R, at a detection range of about 30 nm, indicated that had the RCPs been shifted to SLOW at 0911R, they should still have been acoustically detected - but no such detection occurred.) The electrical load thrown on the vital bus at 0911R by the failure of the non-vital bus with the RCPs in FAST exceeded the capabilities of the vital bus; the RCPs (initially detected at 0845R in FAST as Thresher, according to the deep-dive OP-PLAN, was approaching a depth of 1000 feet) went off-line and the reactor scrammed at 0911R. "[...] "There was not in 1963 - nor is there now - any evidence in the specific case of the loss of Thresher to support the COI conclusion that on 10 April there was a rupture of a silver-brazed, sea-connected pipe that caused a reactor scram. The occurrence of silver-brazing problems earlier with Thresher, and with other submarine hulls, is NOT conclusive evidence that it occurred during the 10 April deep-dive, especially since Thresher's 0913R transmission to Skylark makes no mention of flooding and because the results of analysis of the SOSUS acoustic data are consistent with failure of the non-vital electrical bus which resulted in a reactor scram at test-depth because the RCPs were operating in FAST. Unable to deballast because of a subsequently confirmed ice-formation condition in the high-pressure air lines, Thresher sank to collapse at extreme depth without any prior flooding. Both the pressure hull and all sea-connected systems survived well beyond design specifications. As discussed in The Death of the Thresher by Norman Polmar, Thresher had made some 40 dives to test depth prior to April 1963. "To repeat, there was not - as maintained on page 122 of the WI12TSR - any (quote) failure of a silver-brazed fitting in the engine room, with immediate flooding, and subsequent emergency shutdown of the nuclear reactor (scram due to spray on the engine room affecting electrical control panels) (end quote); hence, it is wrongly asserted, also on page 122, that Portsmouth Naval Shipyard personnel were responsible for the loss of the Thresher because of the failure of a silver-brazed fitting. "The acoustic bubble-pulse data indicate the Thresher pressure hull and all internal compartments were completely destroyed in less than one-tenth of a second (100 milliseconds), significantly less than the minimum time required for human perception of any event: 50 milliseconds for retina integration plus 100 milliseconds for cognitive integration. "[...] "Although this analysis advances an understanding of why the Thresher was lost by establishing there is no evidence of the failure a silver-brazed fitting during the 10 April deep-dive, the analysis still leaves the perhaps unanswerable question of why the non-vital bus failed after two minutes of line frequency instability. "The Thresher was lost nearly half a century ago because her nuclear reactor shut down at test depth of 1300 feet and the crew could neither blow ballast nor restart the reactor in the seven minutes during which Thresher sank to collapse at a depth of about 2400 feet. "Dave Johnston also added: Thresher's inability to blow the ballast tanks had nothing to do with the reactor shutdown. It was a separate problem that unfortunately reared it's head at the wrong time. The blow system had plenty of capacity and it can be manually operated. That was not the problem. When the high pressure air that was used to blow the tanks left the storage banks, it passes through the control valves that keep it in the banks under pressure. Anytime a compressed gas expands, it cools rapidly. As the very cold air passed through the valves, frost began to form due to the presence of moisture in the air. It very quickly built up (a matter of a few seconds) and froze solid in the valves. The solid ice stopped the air just as effectively as shutting the valves, thus the Thresher was unable to blow her tanks...." - www.navsource.org/archives/08/08593.htm I was a bubblehead from April '81 - June '87, though a boomer sailor. While watching a new age music video on KZbin by a Russian artist - whose stage name is Stive (and not "Steve") Morgan - named "K 141 Kursk", I happened to spot an American sub on the surface (3:35) and then, after 3:51, the video revealed the hull number, 593. Not recognizing the hull number, I looked it up, thus starting my research into the USS Thresher (and the USS Scorpion - they are often discussed together, to some extent). Above is some of what I learned.

[@thepotato405]

Woah bro slow down haha. Thats that's taking our understanding of the sub and comming up with the best potential scenerio. From personal experience anything could have happened. Take for example common A-ganger maitnence we were doing while underway we found a cap screwed into a line of piping. This wasnt a subsafe pipe per diagram and once the cap was removed (by a second class literally laughing asking what it went to as he removed it) water began to bellow in until someone stuck their finger in it and was cussing up a storm as to how much it hurt. (Lo and behold it was subject to direct sea pressure). Later investigation by the crew we realized it not only should have been labeled SUBSAFE it wasnt in any piping diagram at all. It should have been labeled subsafe and was manufactured and documented incorrectly. You really cant know why it happened. Especially a sub prior to the SUBSAFE program and prior to modern naval maitenance procedures and regulations. That's the hardest point I try to make with people (especially when they spit out technical data from a whim) with having this conversation because they dont relize unless you've been there and served on them how really easy it is to sink from crew error one of those black bitches. even when we manufacture them and try to get it 100% accurate our SUBSAFE program mistakes are made.

He slid the lagging back and found that the main sea water piping, which has to stand test depth pressure had been cut by a grinder cutting wheel. It would have stood normal sea pressure and greater, but would have burst before the sub would have reached test depth! In short it had been sabotaged to fail during sea trails.

9:33 hatch is blown open. How many atmospheres of pressure would be required for this to occur? How would the hatch crank get bent to the position it's in other than being hit by a solid object in flight causing it to rupture?

[@RichardBonomo]

@@colinmontgomery1956 It is the pressure pulse caused by the sudden inrush of high-pressure water when a deeply submerged submarine hull is breached either due to hull overstress by excessive depth, or the by detonation of an explosive device. As the pressure inside the vessel is 1 atmosphere, and the pressure at (for example) 1000 feet is just over 30 atmospheres, hull failure resulting in substantial water inrush would immediately crush any normal object that has internal voids -- like a man for example.

The prevailing theory on the loss of the Scorpion was a hot-run of a MK 37 torpedo. In that case the immediate action is to reverse course to attempt to cause a safety shutdown of the torpedo. Since the Scorpion was observed traveling in the opposite direction of their intended track the crew very likely had minutes before the overheated torpedo exploded. They likely had time to close all hatches so there was some time to sink to collapse depth for the rest of the crew.

[@LeoAndRas]

There's a thing that I don't understand: if what really happened in this disaster was a hot-run of a MK 37 torpedo, wouldn't had been better to the commander of the Scorpion try to go to surface at full speed, to save at least some lives of the crew ?

[@roypublic3269]

The second part of the video with the Alvin sounds more like a Ballard commercial trying to sell his Jason ROV than the survey they were sent to conduct. A tip to Bob, Submarines do not have nose cones, they have Sonar Domes. BTW For those who are seeking to find the cause, it was never determined exactly. What was found was the Torpedo Room was undamaged, which would Not indicate a hot run or battery fire torpedo explosion. The secondary Navy investigation - using extensive photographic, video, and eyewitness inspections of the wreckage in 1969 - suggested that Scorpion's hull was crushed by implosion forces as it sank below crush depth. The Structural Analysis Group, which included Naval Ship Systems Command's Submarine Structures director Peter Palermo, plainly saw that the torpedo room was intact, though it had been pinched by excessive sea pressure. The operations compartment collapsed at frame 33, this being the king frame of the hull, reaching its structural limit first. The conical/cylindrical transition piece at frame 67 followed instantly. The boat was broken in two by massive hydrostatic pressure at an estimated depth of 470 m (1,530 ft). The operations compartment was largely obliterated by sea pressure, and the engine room had telescoped 15 m (50 ft) forward into the hull due to collapse pressure, when the cone-to-cylinder transition junction failed between the auxiliary machine space and the engine room. The only damage to the torpedo room compartment appeared to be a hatch missing from the forward escape trunk. Palermo pointed out that this would have occurred when water pressure entered the torpedo room at the moment of implosion.

It would be worth comparing these forensic images with dynamic models of the various theories of USS Scorpion's loss documented in a handful of books and documentaries.. The non-crushed bow and torpedo room, the separated sail with positions of masts and antennas are somewhat telling. How do you lose the outer 2 bow hatches and messenger buoy off the ship while leaving the lower bow escape hatch in place? The pressure had to come from above the lower hatch with little bow damage. How to highly pressurize the bow escape trunk from the inside enough to blow off the 2 hatches without hurting the bow??? IMHO the shaft and screw came out as the engine room crushed into Ops - not much holding it in at that point. Model the various explosions/implosions. Has this all been done? Which scenarios can be ruled out and which ones remain? I think many submariners remain curious to see an analysis of these math problems that leave little doubt. I will assume these guys were and are still and forever heroes doing their duty and not submariners who made some error until proven otherwise. Sorry not buying earthquake...there is a real cause.

The thresher. We talked about it a lot while I was underway. What I did not know was that it had Torpedo's with a Nuclear Armament. However, it seems for some reason the boat was was lost due to the Air being frozen in the lines and therefore, it could not come back and float up. But that still does not make sense. Unless they damaged the screw? It should have had an APU? But that thing is only good for maybe 5 knots on a good day. And if they lost propulsion? It would get past test depth in a hurry. It takes a bit of time to deploy these things. By the time the crew knew what was going on? All hell would be breaking loose. The other issue could have been the Electric drive unit. It was still pretty new at the time and from what I understand, it was one of the first built in the 60's. Later on they made upgrades to the screw and other things. The whole thing just seems odd. Ice in the Air lines during an Emergency Ballast tank drill? It just seems odd. But if they did that maneuver, the reduced surface area of the dive planes could make it so that they could not recover. That's my guess. Its crazy that even after all these years? There is still little official info about what was the exact cause.

Zoes Dada There isn’t really a way to “not die instantly” down at such depths. When the submarine hits its crush level, the pressure from the ocean around it is such that it literally crushes the steel, and everything in said steel. Death is violent, but instant. The horrifying part, is being trapped knowing you are going to be crushed to death if the submarine sinks much lower. However, the pressure is so intense, death lasts a split second.

For one thing, there are three hatches in that forward torpedo room. Two are closer together, but a third is further aft. The upper escape hatch and the further torpedo loading hatch were blown open, but a closer lower escape hatch is still shut. If there were indeed an explosion in that space, I would imagine that the closer hatch would have been more impacted than one that's further away. Something else--when you look at that sail and the damage, what do you see on the top of the sail? Notice the fully extended mast that's bent?
