Comments on the ARA San Juan

These things are never easy for me and for my Brothers of the ‘Fin. You try to be stoic about it, but really, the idea of fellow submariners trapped under the waves is something that I certainly have nightmares about.

I don’t want to get ahead of things, and news stories such as the missing Argentinean Submarine, ARA San Juan, can move very quickly. Almost as soon as something is said, it is outdated by new information or is confirmed to be something not related. Given those parameters, and because I have been asked to comment, these are my thoughts. They are grim, but not completely without hope.

(1) They are on the bottom. This actually should be obvious, given that if they could have surfaced, they would have. The question as to where that bottom is and how deep it is as yet have no answers. But the ARA San Juan has sunk.

(2) There were reports of electrical problems. In fact, the reports are what officially prompted the Argentine Navy to order her back to base. There are spurious reports that she had an electrical fire and/or short circuit, but these are unconfirmed and more importantly, not verifiable at all until the submarine is found. Presuming she was submerged when it happened, how would her command know about it if she had not surfaced or contacted them since?

(3) There are reports today (11/21/2017) that she is nearing the end of her seven day air supply. This is a false hope. It is highly unlikely that she was 100% charged when the incident happened. How full her air banks were is obviously unknown, but it was unlikely to be at a full charge, given that she was most likely already travelling submerged due to the high sea state. While she could have snorkeled to recharge batteries and air, how likely is that?

(4) Even if she were at 100%, there are things that can be done to extend the air supply. Again how far they could stretch the air would be a combination of available materials and crew training. Seven days would be the theoretical limit, but it’s possibly to go beyond that time limit.

(5) The ship is powerless. The failure to use any equipment to communicate or make her presence known indicates a complete loss of the ability to operate her electrical equipment. (Stay with me here) If she could make noise, she would. Running her engines or using her active sonar or whatever. In trouble, she would want to attract attention.

(6) The crew is most likely incapacitated. Again, if they were not, they would be banging on the hull, releasing oil or debris, or even attempting an escape. They haven’t done so, which points to an inability to take any action.

(7) There is little support available in the South Atlantic. Unlike the Northern oceans, there is little need to monitor Soviet boats, so there are not a lot of hydrophone or SOSUS arrays in place. There are scientific sound gathering systems, but the time needed to assimilate their data will be too much. It may eventually help in the final search to locate the wreck.

(8) Whatever happened, happened fast. I can postulate several scenarios, from flooding while attempting to snorkel in heavy weather, to shorting in the battery due to flooding, to chlorine gas buildup to loss of propulsion while flooding to an electrical fire (which again, seems unlikely to me as I believe that they would have surfaced) to a hydraulic failure and jammed planes casualty. Anything really, we just don’t have any evidence to really even speculate with accuracy. But it clearly happened fast and it clearly was catastrophic. Anything less, they would have surfaced.

I, of course, have my prayers for the crew and the families, and to be honest, even myself. I can assure you that I have not slept well for the past few nights. I don’t mean to be depressing, certainly I hope for a successful recovery and the safety of the men and woman of ARA San Juan. But I am also a submariner, and I know the risks and the odds.

Hopefully ARA San Juan is the luckiest sub to ever sail the seas.

  1. My thoughts and prayers go out to the families, friends, and of course my Brothers and Sisters of the Fin.
    It’s funny, and Dave back me up on this, the thought of something like that happening NEVER occurred to me while I was underway and submerged. Sure, we trained for just about every type of casualty you can think of and then some…but, the thought of my “boat” betraying me never crossed my mind underway. Maybe it was a mental protective function…maybe I was young and naive, but I just KNEW my boat would bring me home.


    • We had a good ship… and a great crew. And even that didn’t stop her from breaking one night. I don’t recall being nervous at all during the event, but the days after as we slowly made our way back home, were a different story. That was supposed to be my last run, and I was suddenly thinking about whether or not I’d get back!

      We did, obviously, but when we were “ready” to go back to sea, I did not want to go below after the maneuvering watch!


  2. I read your thoughts and while grim, I found them to be honest and, while hopeful, realistic.
    I feel for the crew of 44, and for their loved ones, families, friends and colleagues.
    They have all been in my prayers since learning of their predicament and are most prominent in my thoughts this Thanksgiving Day.
    I would love for every sailor to be rescued alive and return to the waiting arms of their loved ones and countrymen…I wish I could rescue them, or at least recover them for the
    peace of mind of all their loved ones.
    God Bless them and the ARA San Juan.
    Pray for a Miracle.
