Critics Say US Antimissile Defense Flawed, Dangerous

Hugh Pickens writes "The New York Times reports that President Obama's plans for reducing America's nuclear arsenal and defeating Iran's missiles rely heavily on a new generation of antimissile defenses which last year he called 'proven and effective.' Now a new analysis being published by two antimissile critics at MIT and Cornell casts doubt on the reliability of the SM-3 rocket-powered interceptor. The Pentagon asserts that the SM-3, or Standard Missile 3, had intercepted 84 percent of incoming targets in tests. But a re-examination of results from 10 of those apparently successful tests by Theodore A. Postol and George N. Lewis finds only one or two successful intercepts, for a success rate of 10 to 20 percent. Most of the approaching warheads, they say, would have been knocked off course but not destroyed, and while that might work against a conventionally armed missile, it suggests that a nuclear warhead might still detonate. 'The system is highly fragile and brittle and will intercept warheads only by accident, if ever,' says Dr. Postol, a former Pentagon science adviser who forcefully criticized the performance of the Patriot antimissile system in the 1991 Persian Gulf war. Dr. Postol says the SM-3 interceptor must shatter the warhead directly, and public statements of the Pentagon agency seem to suggest that it agrees. In combat, the scientists added, 'the warhead would have not been destroyed, but would have continued toward the target.'"

The real strategy for safety is to reduce the arsenals of former Soviet nations that have a habit of misplacing warheads and to keep a close eye on container ships.

      Low trajectory ICBM's aren't cheap and easy either - they are actually more expensive and difficult than the more normal high loft ones. Why? Because you need the same missile - but a somewhat more sophisticated guidance system and *much* tougher heat shielding on the reentry vehicle.

    Now that presumes, of course, a credible threat from a rogue nations with a few missiles. However, given the developments in NK and Iran, that seems to be a somewhat realistic threat that should be looked at.

    No, there will likely never be an anti-missile system that could deal with, say, the Russian arsenal. You get tons and tons of missiles and it'll overwhelm the ability to intercept them all, or even a significant number. However that doesn't mean a system couldn't provide a reasonable probability of intercepting a few missiles. No certainty, but some chance is better than no chance.

    People also need to remember this isn't pure pie-in-the-sky stuff. The Aegis Combat System is quite capable of anti-missile capabilities. It can track and engage anti-ship missiles quite well. Now of course ICBMs are a whole different problem, not in the least of which because of their speed, but it is the same "track and engage" idea and there is working hardware.

    The real question is if it is worth the cost and overall, I think it is. Reason being that I do see the idea of a missile launch from a place like NK as a possibility. Now if that happens, and the missile hits an American city, it is going to be large scale nuclear war. The US will launch a counter attack. The most optimistic scenario would be that the only deaths would be those from the initial attack, and then more or less everyone in the country the US launched at, but it very well might not end there. The US launch might trigger other launches from other countries.

    However, if the missile is stopped, well then the possibility exists for a more measured response.

    I think that makes it worth it. I don't worry much about nuclear war between large powers. Reason is that the power to make a launch doesn't lie in the hands of one person, and the nations are ruled by sane people. Maybe not nice people, but sane people. They know the consequences, they don't want to see that, the weapons are a last resort kind of deterrent only. However there are places like NK, where a single person rules, and where the sanity of that person is a bit suspect. That is a case where a nuclear launch is a possibility if they obtain the weapons, and they seem to be working on it. That I worry a bit more about.

    So to me, it seems worth it over all. Also let's please not pretend like defense R&D is a 100% sunk cost or anything, that we pour money in to the projects and get nothing useful in return. Often, we get technologies that can be used in other devices or the like, both defense and non-defense. Sometimes, we get things with direct major civilian applications.

    Please remember that GPS was invented because the military wanted to be able to locate all their vehicles and ships accurately anywhere. That was the motivating factor behind it. However it has proved to be the sole most important invention in civilian navigation since, well, since the sextant probably.

    Over all, I think it is worth it and I disagree it is dangerous. Do remember that nuclear bombs are complex, precise devices. You don't have to obliterate one to stop it from exploding, only cause damage to any number of systems and they don't work anymore. Ya the missile might still hit its target but so long as it doesn't trigger the nuclear reaction, the damage will be fairly small scale.
