  1. The USN’S ASW people have a huge (classified) library of underwater sounds. Don’t bother asking me how I know – I’d have to kill you. And I wouldn’t like it, the paperwork’s a bitch.

    Anyway, you can bet your last dollar the ASW people KNOW what a hull collapse sounds like; the transients are unique.

    As for the “objects” traveling at 1000’s of miles/hour, methinks there’s a factor of ten exaggeration there. We (the US) (and the Soviets) have been testing torpedoes and other craft that use ensonified-flow (look it up) around the objects’ body to greatly reduce the friction of pushing through the water. Not new, this research has been going on for decades now. Nobody will tell you anything, though, on the progress or if it is operational.

    What I am saying is this:
    1) you darn betcha the ASW people manning the SOSUS listening posts heard and correctly quantified and identified the hull collapse.
    2) there’s a huge database they have to filter out the regular “noise” that is in the ocean.
    3) it’s an accurate system that can locate when and where something like this happened. The USN knew right after it happened, they are tasked to be on top of something like this 24 hours in the day, 365.25 days a year.
    4) You Don’t Have The Need To Know any More Details than THAT, okay?

    I’d tell you to go talk to Tom Clancy (and others), but he’s dead Jim.

    • Thank-you Aesop. Glad to know that every underwater sound is classified.

      You never fail to impress.

    • And they NEVER said anything because the news media was nicely distracted from the Biden Crime Family revelations with the story of a potential “rescue” to upset things with THE TRUTH.

    • They used to be on top of this type of thing. Today the navy is more worried about pronouns than war fighting. I bet no one was listening in real time, cause they got more important things to do, like planing the next drag show, but they recorded it and checked the tapes after-the-fact. That explains the delay.

  2. I think they are beginning to prime the pump that the fake alien invasion will actually come from under the ocean.
    Military: “We’ve known the aliens have been here for years in their underwater cities. We are monitoring the situation.”

  3. after the Clancy book came out,, it was must reading for a lot of people that walked the halls of CGSC at good old FT. Leavenworth. a lot of questions where asked
    and a few people in the know fill in a few blanks. a lot of the “tech” started back in
    WW2 and was improved upon over time.
    think of it as a picket line underwater. and they can tell when and where something
    the stupid sub imploding happen. now the info was not release due to polyticks
    as you well image. why have the dirty news about the clown in charge when you can have people talking about a bunch of morons in a homemade sub ?
    drama is everything in the “news” today.

    • Looking at the sub it had a main hull and 2 smaller tanks that i read somewhere are for buyouncy /ballast. I suspect the sound of the main hull imploding vs one of the secondary tanks imploding would be similar. If I was the head of the search party i would want confirmation before i scalled back the search. The bad PR of saying it imploded and stopping the search then finding out later the sound was from a tank not the main hull would be immensly bad.

      I dont think thats why they did it, i think it was a media distraction as cover for the biden crime family inc.

  4. I read most of Clancy‘s early day novels extremely entertaining and very prescient about our future at the time. The van in the Phoenix airport, cell phone lot and the guy who jumps out with a man pad has yet to come true.

  5. I was in that career arc back in the 80’s, and the Tom Clancy novels were almost a requirement of the field. If there was an implosion it would have been located by triangulation, and a search posit generated, but I’m not sure if my old equipment is still even being monitored anymore. My rate OT, has been eliminated and so we’re the facilities for monitoring the signals.
    The implosion would not have stopped the search, because if it was the main hull, no rush, its over, and if it was a different signal imagine finding the pressure hull 3 weeks from now filled with soup from 5 corpses trapped inside. That would be a tragedy and a career killer for the entities that stopped the search.
    Better safe and sure than sorry and maybe we could have been saving them if they were bobbing along at surface level.

  6. SOSUS was instrumental in locating the wreckage of the USS Scorpion (SSN-589), which disappeared enroute to Norfolk VA in May of 1968.
    Read “Blind Man’s Bluff”, by Sherry Sontag and Christopher Drew, for this story and other submarine shenannigans during the Cold War.

  7. Installed in the 70’s and they’re still functioning effectively today, 50 years later?
    How?

    Define implosion.
    It doesn’t require much of a sound.
    Nothing blew apart.
    The layers in the hull wrappings separated allowing the water pressure in.
    The pressure equalized in less than a second.
    The hull is mostly intact.
    Yes, they knew 2 hours after launch, at about 9:14 am.
    The rest is theater.
