Chinese scientists say cheap SQUID submarine detector is world’s most sensitive

      Indeed, also the whole AUKUS thing that’s estimated at a third of a trillion dollars at the start, and reaching the working capacity of “blocking China’s sea with submarines” by 2040, turns out to be stillborn. By 2040, these ancient huge submarines will be easily detectable, and will be destroyed by a swarm of underwater drones.

      This is a similar situation to how vulnerable tanks are to FPV drones. US clearly didn’t consider the impact this sort of tech will have on the future of warfare, and doesn’t have any clear response at the moment. Funny part is that US is now starting to fall behind technologically, so they don’t have symmetric capability to detect Chinese or Russian subs.

          I very much agree, now that US transitioned to a largely financialized economy, the mechanisms for doing domestic industrial capitalism are no longer present. The whole political and economic system would need serious restructuring to do that.

            That’s the beauty of it. The first baby step they would take to undo the past forty-fifty years would reveal the paper beneath the tiger face paint. The joy that I get from watching the west collapse is going to help keep me warm as my life in the west becomes unaffordable lol. Silver linings and all that.

        Only if the purpose of the fleet is to win wars. That’s 16 years of purchase orders. Look at the F-35.

        I don’t actually know anything about AUKUS but I don’t see the problem.

      Aren’t there 11 US aircraft carriers each of which can topple a small nation? IDK if id say nuclear subs are the last advantage lol

        Yes, they can topple small nations (though not really, it never actually happened), that’s what they have been designed to do, to work as the XX-XXI century gunboat diplomacy, not to actually strike alone but to make terror threats of destruction.

        But their usefulness is currently around zero in a peer combat against Russia or China, hypersonic missiles are hard counter for them. And note that US is even reluctant to post them nearby Iran because Iran also have some dangerous to them weapons like supercavitating torpedoes.

        US Navy surface fleet is therefore pretty vulnerable to PLAN which got close to force parity in defence scenario, but nearly all PLAN ships are more modern and will have advantage in defense because being on the other side of Pacific.

        So the only real and big advantage US Navy have is their submarine fleet which is much bigger than Chinese and make exclusively of nuclear submarines which in itself is advantage especially on area as huge as Pacific. No wonder China put some serious money and brainpower to this research.

            If he was this angry back then, i wonder what he said when Chinese published their war games results when the results was just 20 hypersonic missiles was needed to nearly entirely obliterate carrier group.

            Minus for obnoxious jeune ecole vibes though.

              At least a few years later I kept flip flopping for a while between “eh, maybe they have some defense system at this point, I sure wouldn’t give away that knowledge for the tactical advantage” but it’s been like 15 years now and nothing so I’m pretty sure they’re still at “expensive coral reef when facing anything but insurgents”-status

                The article is incredibly reductive though, as every jeune ecole type always is. Note that PLAN is the navy who is pioneering the new methods but they still build the surface ships and even carriers. I would probably bet for PLAN staff to know a little bit more than some warnerd random guy.

                Also his proof is bad too. One example he have is the very abnormal sinking of Israeli destroyer - the attack was basically surprise attack from minimal range using cutting edge weapon against old WW2 destroyer not having any antimissile system. Second is corvette of Nanuchka-II class not having any antimissile systems either. So he chosen examples of ships not having antimissile systems as examples of antimissile systems not working, how brilliant!

                He also fail to mention yet again what all naval jeune ecoles in history did - the sea. Massed missile cutters are good on littoral waters, but completely lose it on a high seas. he’s more correct about submarines, but that is not freeze in time either (i mean we are discussing under precisely such article).

                What of course comes into play is the doctrine, note that US Navy needs different doctrine because for over 200 years it is purely offensive navy with power projection abilities in the entire Earth, while both Soviet Navy and PLAN were build clearly for defensive role. US literally cannot resign from the conventional navy, but neither can China since Pacific is so big. Russia due to geography can and as you can see, is doing that, they basically do not even to try to replace the big surface ships (last destroyer was comissioned in 1993), they go for frigates at most and submarines.

                EDIT: I just went to check the list of ships sunk by missiles, and with possible exceptions of Russian cruiser Moskva which might or might not be sunk by missiles, none of the ships sunk in combat conditions by missile ever were equipped with antimissile systems.

          Also consider that in a fight with China over Taiwan or the West Pacific the US surface fleet will have to also deal with shore based aviation and ballistic missiles.

          The old adage that a ship should never try to fight a shore battery probably holds true to this day.

      I imagine that’s precisely the idea there. A sub is fairly limited in the amount of torpedoes it can carry, so a big enough swarm of drones becomes literally impossible to stop.

        It’s kind of odd how every hardkill system seems to have the fatal flaw of “well what if there’s a bit more of the stuff you’re supposed to stop”

          The US designed it’s fleet based around one big heavy attacking another big heavy. It’s in their nature to want a big threatening bully of a ship. It also helps that big heavy threatening things are magnitudes more expensive than smaller more effective things. The whole navy is this way. Its why we have so many carriers and why they get their shit pushed in in simulation after simulation by a force that instead uses a whole bunch of smaller ships.

            Well actually also it’s designed around one big heavy bullying a few smaller under equipped ships and or attacking smaller nations that aren’t capable of defending themselves.

    “But it’s cheap! That means it’s bad! They need to give at least several billion to the CEOs of big military development companies before a sonar system can work, everybody knows that!”
