Scorpion (SSN-589)

Radio Call Sign: November - Victor - Charlie- Foxtrot

Skipjack Class Attack Submarine: Laid down, 20 August 1958, at the Electric Boat Division, General Dynamics Corp., Groton, CT.; Launched, 19 December 1959; Commissioned, USS Scorpion (SSN-589), 29 July 1960; Last reported position, 21 May 1968, about 50 miles south of the Azores. Six days later, she was reported overdue at Norfolk; Crew declared "presumed lost," 5 June 1968; Struck from the Naval Register 30 June 1968; Final Disposition, in October 1968 Mizar (T-AGOR-11) located sections of Scorpion's hull in more than 10,000 feet of water about 400 miles southwest of the Azores. Subsequently, the Court of Inquiry was reconvened but, despite the myriad of data and pictures collected and studied, the cause of the loss remains a mystery.

Subj: Why the Scorpion (SSN-589) Was Lost on 22 May 1968

When the US nuclear submarine Scorpion was lost in the east central Atlantic on 22 May 1968, the event produced a series of acoustic signals detected by underwater sensors on both sides of the Atlantic.
By comparing the detection times of these signals, the position of the Scorpion was determined. That position provided the basis for the search that identified the Scorpion wreckage.
The first reanalysis of these acoustic signals in 40-years, in combination with conclusions drawn in 1970 by the Scorpion Structural Analysis Group (SAG), has provided the following new information:

- The initiating events that caused the loss of Scorpion were two explosions with an energy yield of not more than 20-lbs of TNT each. These explosions, which occurred one-half second apart at 18:20:44 Greenwich Mean Time (GMT) on the 22 May 1968, were contained within the Scorpion pressure-hull,
- Based on the examination and microscopic, spectrographic and X-ray diffraction analysis of a section of the Scorpion TLX-53-A main storage battery cover recovered by the U.S. submersible, Trieste-II, the SAG determined the battery exploded before flooding of the battery well occurred.
- Collectively, the acoustic data and the physical evidence confirm Scorpion was lost because of two explosions that involved the ignition of hydrogen out gassed by the battery, i.e., these explosions were the initiating events responsible for the loss of Scorpion.
- These explosive events prevented the crew from maintaining depth-control. The Scorpion pressure-hull and all internal compartments collapsed in 0.112-seconds at 18:42:34 GMT on 22 May 1968 at a depth of 1530-feet. The energy yield of that event was equal to the explosion of 13,200 lbs of TNT, the essentially instantaneous conversion of potential energy (680 psi sea pressure) to kinetic energy, the motion of the water-ram which entered the pressure-hull at supersonic velocity.
- The more than 15 acoustic events that occurred during the 199-second period following pressure-hull collapse were produced by the collapse of more pressure-resistant structures, including the six torpedo tubes, within the wreckage.
- Reanalysis of the acoustic data also confirmed:
(1) Scorpion did not reverse course to deal with a torpedo conjectured to have become active in its launch tube;
(2), there were no acoustic detections of either a torpedo or any other naval surface ship or submarine when Scorpion was lost,
(3), there were no explosive events external to the Scorpion pressure-hull.

In summary, Scorpion was lost because two battery-associated explosions created onboard problems the crew could not overcome. There was no Soviet involvement.

This information has been provided to the Chief of Naval Operations, OPNAV N87, the Office of Naval Intelligence (ONI), Commander Submarine Forces, and the Naval History and Heritage Command.

Mk 37276kMk 37 Mod 2 torpedo of the type carried by the Darter (SS-576), and other submarines during the Cold War. A 19 inch diameter weapon powered by batteries, it swam out of the tube instead of the traditional impulse shot, making it hard for the enemy to detect.
Early versions of this torpedo were notoriously finicky. An overheating battery that lead to an explosion is one of the leading theories of the loss of the Scorpion (SSN-589).
During the 80's, the Darter normally carried two of these weapons in her after torpedo room, although up to four could be carried if two were tube loaded. Carried as a supplement to the normal load-out of Mk 48's in the forward torpedo room, they were mostly intended to be shot at pursuers during an evasion.
The Darter had the honor of shooting the last Mk 37 exercise rounds during a Tactical Readiness Evaluation at Pearl Harbor in June, 1985. That same month she offloaded the last operational Mk 37 war-shots, sending them to storage.
This particular weapon is part of the Lexington CVT-16 museum at Corpus Christi, Texas.

Scorpion 135k Scorpion (SSN-589) memorial in NOB Norfolk VA.

The Thresher sank during the deep dive portion of Phase C Sea Trials in April 1963. Quite a bit was known (and later discovered) about the Thresher disaster. Sadly, the same cannot be said of the sinking of the Scorpion (SSN-589). The Scorpion was lost during a mission in 1968 and while the U.S. Government convened inquiries, it has never issued any official explanation or cause of the loss, and instead has left the door open to several theories. This lack of closure is a void that has over the years been filled by poorly researched cloak-and-dagger accounts of the loss of the Scorpion.
The following is a copy of a letter written by Neal Collier to the Scorpion Families on the Scorpion-99 Yahoo Group. It was written in response to the most recent of these ‘un-official' accounts. It is reprinted here because it contains some Thresher-related information, but more importantly to show that these two ships, the men that were lost, and the families and loved-ones left behind are inexorably linked in history – past, present, and future.

For the Scorpion 99, John Howland
I was 4 when my father was lost on the Thresher (SSN-593) . He had transferred on as the Engineer's relief just prior to Sea Trials. I don't think he was even part of the crew for more than a few weeks.
I went in to the Navy myself – many different reasons – and ended up on the Archerfish (SSN-678), meeting the boat in the Med. After about a year we went to the Portsmouth Naval Shipyard (PNS) for an overhaul. The PNS was where the Thresher had undergone her last overhaul, and from which she went on her last dive. While there I took the opportunity to speak to a LOT of SY Workers and Navy types. I discovered that the PNS took the Thresher sinking very seriously and take the hard-earned lessons to heart in everything they do. The Shipyard lost officer observers and civilian Shipyard workers when the Thresher sank. Many people forget that. Each and every person that I spoke to who worked on her or remembered her was reduced to tears when we discussed the tragedy.
So what happened? Why did the Thresher sink? The sad fact is that usually the reason bad things happen is that humans are involved and humans, well, they make a lot of mistakes. For the Thresher, there were so many mistakes made it is difficult to name them all. One that comes to mind is the depth of water in which she sank. Test Depth is a certain depth. It's classified, but for argument's sake let's say Test Depth is 400 feet. (It is deeper than that, but we'll use that in this example.) If you were conducting deep depth test and the boat could only go safely to 400 feet, you probably would want to be in water that was just a bit deeper than that. You would also want to have the ability to provide support if trouble occurred. The Thresher was on the way to Test Depth in water that was about 8400 feet deep and no rescue vessels were in the vicinity. Think about the monumental arrogance and stupidity that resulted in that location being chosen. There were others, but the gist here is that many, many mistakes were made. From that tragedy, though, came many positive changes. SUBSAFE was the big one. Design and operational changes occurred, too.
- SUBASFE - A complex and comprehensive submarine overhaul maintenance and repair management system with checks and double-checks to ensure any / all critical operational and safety components are thoroughly tracked, tested, and checked after maintenance, repair, or modification prior to allowing them to be released for use.
- Moisture separators on the High Pressure Air Compressors (HIPACS) to remove moisture known to cause the 'Venturi Effect' which freezes the Tank Emergency Main Ballast Tank Blow Valves when they are needed the most.
- Prior to the Thresher disaster, submarines were routinely put through a gauntlet of depth charges causing structural damage that was then measured and evaluated. This is no longer done to operational vessels.
- Fast SCRAM recovery. The ability to rapidly and safely bring the reactor (the steam source for the engines to turn the propeller) back from a shutdown state.
- Equipment Cooling. Prior to the Thresher, equipment was cooled mainly from pipes that carried seawater through tubes that cooled the equipment. This meant that there were many feet of pipe throughout the sub carrying water at extreme pressures. Design changes were made to install large heat exchangers that transferred cold from the seawater to fresh water at much lower pressures. The fresh water was then pumped to the equipment to cool it.
- Silver brazing and radiography. When pipe was cut and welded, a special silver braze was used to seal the weld and make it water tight. Silver welding was hard to get right and many welds were not able to withstand the pressures to which they were subjected. This practice was ultimately stopped. In addition, very few welds were looked at using radiography (think of the dentist looking at your teeth). Taking radio-graphic pictures of critical welds is now done (and in some cases re-done) for all piping and hull welds.
The above are a few major examples. I hasten to add that the Thresher did not 'create' these changes; they (and many more) were already being studied, debated, and discussed at the time. The Thresher was only the catalyst to make them happen; to push it through Congress.
I do not know a lot about the Scorpionbut have read a few books and accounts. From a Scorpionperspective, I think the article from Proceedings (July 1998) summed it up as the Navy just did not learn the lessons from the Thresher. A stuck Trash Disposal Unit (TDU) valve was postulated as the most probable reason the Scorpion was lost. A guy I knew on the Shark (SSN-591) (sister ship to the Scorpion) said that TDU valve got stuck on a mission and the Captain would not let anyone touch it until they got into port. They must have been teaching that as a potential problem at Prospective Commanding Officer's (PCO) School.
People just like the sexy conspiracy stuff, I guess. Revenge for the sinking of the .... Wait a minute. What, now? Our culture loves a good story and we want so desperately to believe the unbelievable. When in Orlando at a Navy service school I heard of the "Thresher Tape" where supposedly members of the crew left messages to loved ones that the Skylark (a recording and communications ship) picked up before she sank. I heard this from many different people at different commands. I searched at several different commands in a vain attempt to find that recording. It took me until years after I got out of the Navy to come to the realization that it was baloney. A family friend (USNA '56) explained it to me this way "OK, the ship is sinking. Are you going to work like heck to fix it, or are you going to line up outside the Radio Room to record a message?".
I was at a Naval awards ceremony a few years back and a female officer (LtCDR) informed me at the reception that her husband told her of a top secret mission where the Thresher actually had SEALS on board during Phase C Sea Trials. I have to tell you, had I said to her what I was actually thinking at the time, I probably would have been thrown off that base.
There are other examples (too many, unfortunately). People who you would think know better don't. There are all these crazy theories and stories. Thankfully, there are no books written about the Thresher (except maybe the Polmar book), so I don't have to go through that. I was recently lent a book about the 'secret' submarine war by a co-worker who is also ex-Navy. After a quick scan I was not happy with what I read and did a web search on the book. The results (poorly researched, mostly fiction, etc.) confirmed my suspicions. I spoke to the guy who lent it to me, explaining how I would feel if idiots who actually believe the tripe sent out via emails wrote a book about some plot against the Soviets involving the Thresher; involving these noble men who gave their lives for their country; cheapening their memory and honor for a few bucks, for some fame, for --- what exactly? When I told my co-worker this he leaned back in his chair and said very humbly, "I hadn't thought of that."The crazy theories and stories make me sick and angry, to be honest. They create a false and phantom history and – in my view – move the discussion farther away from where it needs to be: how can we create a stronger and safer submarine force and never NEVER let this kind of tragedy happen again?
OK. I have said enough. As a closer I would say that we need to be vigilant, to keep the memories alive, and to stay true to our loved ones and their memory through memorial services and discussions. We need to keep the memory of those lost – and how they were lost – alive for this and future generations.
1 - "Those who don't know history are destined to repeat it." Edmund Burke (1729-1797)
2 - We honor those who we love and respect. When we stop doing that we lose our humanity.
3 - Memorial services give those who have not grieved the opportunity to do so when they are ready.

In Memorium:
In the Second Book of Shmuel (Samuel), 22nd chapter, 5th through the 19th verses, translated from the original in Hebrew and published by the Koren Publishers of Jerusalem, Israel, can perhaps aptly describe the fate of the crew and all other U.S.sailors who died defending their county:

"When the waves of death compassed me / the floods of ungodly men made me afraid; / the bonds of She'ol encircled me; / the snares of death took me by surprise; / in my distress I called upon the Lord, / and cried to my G-D: / and he heard my voice out of his temple, / and my cry entered into his ears. / Then the earth shook and trembled; /the foundations of heaven moved / and shook because of his anger /...the heavy mass of waters, and thick clouds of the skies /... And the channels of the sea appeared, / the foundations of the world were laid bare, / at the rebuking of the Lord, at the blast at the breath of his nostrils. / He sent from above, he took me; / he drew me out of many waters; / he delivered me from my strong enemy, and from those who hated me; for they were too strong for me. / They surprised me in the day of my calamity: / but the Lord was my stay..."
