His name is Stross. Charles Stross. And he writes about the X-band radar system:
Charlie's Diary: Paging Dr Evil (or, Who designs these things, anyway?): The Strategic Defense Initiative (aka "Star Wars" program) has, since Ronald Reagan announced it more than 20 years ago, cost the US government more than US $100Bn.... There are about ten interceptor missiles available, and the current goal of the project is to pop a cap in the ass of any rogue state that tries to destroy the United States by launching a single 1950s-vintage ICBM with a single warhead and no countermeasure capability.... However, there is one leetle weakness in the BMD program. To hit a missile with a missile requires fairly accurate radar -- it entails accurately tracking a target the size of a dustbin at a range of several thousand kilometres -- and so they've also developed an appropriate radar system. The sea-based X-band radar system... looks as if it sailed in out of a Bond movie: a $900M fifty thousand tonne offshore platform with a 1800 ton radar installation on top of it, it's designed to sit in the ocean near the Aleutian islands and spot incoming sub-orbital trash cans and guide the rocket interceptors into the target.
Unfortunately, there's a problem with it.... [A]ny budding Doctor Evil can ensure the success of his orbital mind control lasers or terrorist ICBMs by... sending... a 1950s vintage Whisky class diesel-electric submarine to poke a pointy stick through the eyes of the ballistic missile defense system. Which is, you will notice, not exactly mounted on a vessel that's capable of fighting off a bunch of Malacca Straits pirates.... I don't know about you, but I'm coming to the conclusion that the Pentagon subcontracted this job to the same guys that James Bond's enemies always hired to design their headquarters -- you know, the one with the prominently labelled SELF DESTRUCT button. (That would be Halliburton and Brown & Root, right?) I mean, what other explanation is there...?
I am told that the vulnerability of the X-band radar to pretty much anything with explosives, and the absence of two rotating carrier battle groups to protect it would be a serious defect in the system--if it worked, and if it couldn't be spoofed.
But I am also told that it doesn't work. And that it can be spoofed. So the vulnerability of the radar problem is only a third-order flaw in the system as it stands.
Impeach George W. Bush. Impeach him now.
