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.'"
Their real point is successful intercept of the entire missile body != intercept of the warhead, not that the intercept missed entirely. Of course, the SM-3 system has actually done an exo-atmospheric intercept (failing satellite over the Pacific).... (speaking as someone who actually used to run a ship capable of doing this.)
a warhead is pretty fragile and a lot of things have to work in unison and perfectly together to produce a nuclear explosion. if you hit it hard enough to damage it and prevent an explosion it's good enough
...and I can tell you that our flight tests have demonstrated our ability to not only hit the target, but decide where to hit it. We have advanced FEA simulations that determine exactly what damage we're going to do when we hit it at a given location at a given angle, and our organization supports our current aiming techniques as "lethal." Given that we tend to aim very reliably, it sounds like the argument here simply about aiming location, which is the result of a few parameters in the software. That's a completely different story than saying the entire system is flawed.
Yep, I do see a pattern. People paid to hold an opinion (in this case the pro-shield ones) are quoted as "experts", yet, people that form an opinion on their own, based on aquired knowledge are quoted as "anti" or "pro-cause".
It is like some of the money is flowing to the ones quoting people, but who am I to know, I'm probably some anti-lucrative-press or something like that.
