Postmortem

By lex, on November 24th, 2010

The forensic analysis of the sinking of ROKS Chonan, for those who haven’t seen it. Complete with slides showing the damages incurred when a torpedo’s pressure wave breaks a ship’s back.

Pretty convincing.

    “The North Korean military is in possession of a fleet of about 70 submarines, comprised of approximately 20 Romeo class submarines(1,800 tons), 40 Sango class submarines(300 tons) and 10 midget submarines including the Yeono class(130 tons).

    It also possesses torpedoes of various capabilities including straight running, acoustic and wake homing torpedoes with a net explosive weight of about 200 to 300kg…”

    Hope the Gee Dub folks are up to speed on ASW skills. Lunatics with 70 subs can cause a lot of problems. As the saying goes “…they only have to get lucky once.”

      I’ve been out of the loop for a while now, but I’d imagine the Nork boats would have acoustic signatures similar to that of a garbage truck? Hear them shortly after coming out of port probably?

      If the CVSG doesn’t go in with its ears tuned from the beginning, the subs could snorkel their diesels and it wouldn’t matter. I’ll upgrade from my earlier post–>we need 2-3 SSN’s slithering about for Force protection.

    Sorry, but you don’t hear a diesel boat running on batteries.

    I imagine there’s more than a few diesel engines running in the Yellow Sea. The problem wasn’t trivial when we had a lot more ASW tools than we do now.

      It’s always been an awful place to play cat & mouse with subs, especially those pesky diesels. Hate to try it now with a fraction of the P-3s once available and the atrophied skills of the crews.

    Interesting article.

    Am I the only one who looked at that class of ships and thought “Well, that’s what an LCS design should have come up with.”

    I’m just an ol’ grunt.
    Like Todd said, isn’t attack subs part of the package?

    1. The ship remains should be displayed in downtown Seoul to remind the southerners of the “maximum restraint” that the NORKS continue to exhibit upon the request of China.
    2. Remember numerous war games at the old TacTrainingGruLant. Datum invariably was flaming. Diesels in shallow confined fishing-boat-filled water will always have the advantage in either an active or passive scenario. just motor around near a fishing boat and wait for the opportunity.
    3. Never take a knife to a knife fight.
    4. One can only hope that current naval ROE does not mirror that crap used in Afghan. don’t go in with some JAG standing over the admiral’s shoulders counseling “further restraint” when USS ___________ goes “boom”.

      Umm, send in destroyers, and have ‘em ping like hell, all the time? I mean, they know where the DDs are, so yer not giving anything up that way.

      I concur with those who lament the decay of our airborne anti-sub assets. This really is Serious Business, as they say on the Internet.
