Missile Defense Test Intercepts ICBM Target, Says Pentagon (cnbc.com) 109

schwit1 quotes CNBC: In the first test of its kind, the Pentagon on Monday carried out a "salvo" intercept of an unarmed missile soaring over the Pacific, using two interceptor missiles launched from underground silos in southern California.

Both interceptors zeroed in on the target -- a re-entry vehicle that had been launched 4,000 miles away atop an intercontinental-range missile, the Pentagon said. The first interceptor hit and destroyed the re-entry vehicle, which in an actual attack would contain a warhead. The second interceptor hit a secondary object, as expected, according to a statement by the Pentagon's Missile Defense Agency.

Missile Defense Test Intercepts ICBM Target, Says Pentagon

  • When we are pretty sure we can live without worrying about large scale salvos of missiles between countries, I think the world will end up being a more peaceful place (in aggregate, not for all areas of course humans being what they are).

    Between that and hardening agains EMP (which will happen naturally anyway at some point from solar flares) we are actually doing things that will matter on a country-wide scale.

    • EMP hardening was called 'EMI interference reduction'. The USA passed it's law in 1982.

      Just as an example: Recent testing shows most cars will stop when hit by an EMP. But will start right up again.

      • The USA passed it's law in 1982.

        Awesome! So what effects did that "law" have? What was that called again? I guess since it was passed way back in 1982 the electrical grid must be totally OK with a an EMP attack!

        Or wait, maybe we can actually improve on something to make it more robust? GASP!

        • https://en.wikipedia.org/wiki/... [wikipedia.org]

          Sure, you can always improve shielding, but 'good enough' is good enough.

          FYI you shield electric transmission by burying it. Like we've been doing with local service for decades now.

          Shielding high voltage transmission is a difficult problem.

          • Shielding to protect against accidental inference with other electronics is quite a lot different than shielding to protect against something on the scale of an actual EMP attack, or Carrington event.

            Sure, you can always improve shielding, but 'good enough' is good enough.

            Not necessarily for an EMP attack.

            FYI you shield electric transmission by burying it.

            Yes you do! So you are saying there are no overhead power lines left, fantastic.

            Oh wait, there are? So we could still improve that factor? Huh!

          • FYI you shield electric transmission by burying it.

            EMP works through electromagnetic induction. How do you propose to shield buried cables magnetically? They'll still get affected. [wikipedia.org]

            • Well, to be fair, if you bury them deep enough...

            • Q: What is the resistance between two points of a large solid sphere made of high resistance material?

              You should have worked that question in highschool calc. Explained how 'ground' works. A: 0 Ohms.

              You could have further done a little research on the engineering of buried cables. Hint: Conduit and/or grounded layers to control capacitance.

              • And that has to do with electromagnetic induction in large-area current loops from varying large-scale magnetic fields...uh, what exactly?
                • The conductivity of the material doesn't effect eddy currents in your conceptual universe?

                  You need to retake fields, or take it for the first time. If you've never taken it, you should shut up now.

      In terms of actual military technology this is nothing new. The announcement makes it sound like they independently tracked a missle launched from an unknown base, found it in the air and launched an intercept that succeeded. Instead, this test is just another in the "yep, when we know exactly where things start from, exactly how fast they are going, and position our counter at exactly the right distance away, we can hit the dummy". The US is adopting the old Soviet style of exaggerating military achievements and filling gaps with braggadocio.

        Good. Missile defences that others think might work are much better for stability than ones that host countries know will work. The defender knows they're vulnerable, so they don't do anything stupid. Potential attackers can't be sure an attack would succeed, so they don't do anything stupid either.

        • No, missile defenses don't work on a strategic level opponent. If China/Russia wanted to nuke us, and wasn't sure how capable the missile defense was, they'd merely lob over 5X more missiles than they originally intended, and have them MIRVed (Multiple Independent Re-entry Vehicles). In other words, they would merely overwhelm the missile defense system. Also realize its much, much cheaper to build more missiles than a missile defense can effectively respond to. Finally, no nation has MIRVs with glide

          • by ceoyoyo ( 59147 )

            Yes. That's what I said. The best missile defence is one that doesn't work. If the US thinks their missile defence works, they might do something stupid. If they know it doesn't, less chance of stupid. If the Russians or Chinese or whoever don't think it works, MAD is maintained as usual. If they think it does work, for whatever reason, they're less likely to launch, not more.

      • by gtall ( 79522 )

        Bullshit, they simply announced what they'd done.

      • by rtb61 ( 674572 )

        Nope, this is a new level of stupid from the US military. Missiles are changing, they will no longer fly a ballistic trajectory because the US dropped a certain missiles treaty, so now the solution to targeting each others capital cities, is long range stealth cruise missiles, which fly close to the ground as speed and can no be currently effectively detected until it is too late, they will destroy the anti-missile system and the target is was meant to protect.

        Even with ballistic missiles, only one change

      Arguably, that was a solved problem between rational nation states. Mutually Assured Destruction kept us safe for 40 years during the Cold War. Either side could rain a salvo of missiles on the other, but neither did because they feared likewise retaliation.

      A missile defense technology is really only effective against a rogue attacker who is crazy enough not to care about retaliation. e.g. North Korea flinging a missile at the U.S. west coast. And the bigger issue moving forward will be a small terrorist organization or a nation state sneaking in a nuke via a suitcase or car, and detonating it. Uncertainty over who exactly perpetrated the attack prevents retaliation, making it the perfect means for a weaker power to attack a stronger one. Missile defense doesn't protect you from that.
      • Either side could rain a salvo of missiles on the other, but neither did because they feared likewise retaliation.

        Also, most people in both countries didn't actually want to be killers of millions and millions of people.

        We now have a different, more effective form of MAD. Instead of relying on the arguable love of a nuclear power's leader for his country, we now can rely on the love of that same leader for money. Putin, Xi Jinping, et al. are the richest people on the earth. By starting a nuclear war, they risk their money, since a decimation of the world's economy will rob them of their wealth. The intertwining of the global economy across countries makes the world safer by making the world's leaders dependent on the

    Well below Russian re-entry ballistic warheads's speed, which will be at least 5x to 10x higher.

    • by Jzanu ( 668651 )
      Russia's nukes are obsolete. They test freight-car sized prototype weapons trumped up to sound like they are space age super-weapons. They field rusting Soviet era hulks without guidance systems and without men or facilities to fuel, launch, or even maintain them. Russia is a failed state run by a corrupt criminal with delusions of genocide, while all the people would be infinitely better off if Vladimir Putin could just catch a few bullets between the eyes.

          I'm sorry but I have no respect for Vova he is a lazy and weak pussy who destroyed Russia's economy, its military,and all of its nascent democratic institutions so that he could profit personally by stealing everything not nailed down. Then he brought out the nail remover to steal the rest. Putin hates Russia most of all.

        delusions of genocide

        Did you maybe mean grandeur? I am not aware of any genocidal ambition on the part of Putin. Its not hard to believe he might hold some idea of racial superiority but I don't see him engaging in ethnic cleansing etc.

        Russia is not a failed state. Russia is a failing state; there is a difference. Broadly speaking Russia still has a working bureaucracy and government can and does enforce its laws. That said they have an economy that is increasingly becoming an petroleum/chemical mono culture in a world whe

          Let me introduce you to the Georgia-Russia War [wikipedia.org]. A quick and nasty little bit of Russian military intervention. They are currently preparing the war crimes trials [cnn.com] from this very short 5-day war. That's a bit quick for war crimes unless you really wanted to get rid of parts of the civilian population as a general principle. Then there is Russian takeover of Crimea and their intervention in Ukraine. I'm not sure many of the citizens of those places would agree with you. Ethnic tensions and playing on the

            Ah, "genocide" has been watered down to mean a few hundred casualties. Awesome, another word rendered useless.

        Every single time they fly a rocket to ISS they are testing their ICBMs, all Russian ICBM rockets are R-7 rocket based. Exactly the same rocket base used in Soyuz space craft. If they can dock on ISS ,they can deliver a nuke on your roof, probably with even better accuracy.

        Decades? They build the engines and rockets bodies and launch them twice a month in the Soyuz format or launching satelites with 0.03% failure rate over 45 years. Do you really think they do not have any spare engines or bodies from R-7 r

          Um, the R-7 design really isn't that practical as an ICBM. It uses LOX, which means it has to be fueled up right before launch. Sure, it may have originally been designed as one, but everyone quickly realized that hypergolic storable propellants were far better suited to that job.

  • Can those missiles fly at all after decades? Who would be so brave to launch one not knowing where it lands. Amusingly, only North Korea has a recent experience with it.
    • by Strider- ( 39683 )

      The US regularly conducts missile tests, both from land based solos and submarines. There is typically one or two launches a year to verify operational readiness. The missiles used are pulled from active service, have their warheads replaced with dummies, and fired at Kwajalein.

  • While it's good that they can intercept ICBMs, I suspect the only thing this will accomplish is spurring the development of anti-interception ICBMs. Naturally, development on anti-anti-interception ICMBs. The perpetual development of intercept and anti-intercept technology will continue back and forth ad nauseam.

      Too late...Multiple independently targetable reentry vehicles [wikipedia.org]

  • Yeah, now try intercepting a salvo of 4000 of them, at the same time, each with multiple separate warheads. Heck, try to intercept even a few dozen. This is a very asymmetric problem that's very unlikely to be solved to any kind of satisfactory degree.

    • There won't be a salvo of 4000. Outer edge of plausibility might be 100 or so, from only the large players (who aren't going to be doing it). Intercepting 25% will save *millions of American lives*, 50% tens of millions. Is that what you are objecting to?

      • > might be 100 or so, from

        Assuming this scenario for a moment....

        That's enough warheads to drop 3 on the 30 largest cities in the US.

        The system has no capability to shoot down this many. This is doubly true because anyone able to launch that many will also launch hundreds of high-quality decoys that the system is unable to distinguish (as opposed to low quality ones from other nations)

        Because of the overkill on those targets, shooting down even the majority of them will have almost zero effect on the out
