Astrophysics Lines: 19 The X-ray lasers currently under consideration are strictly one shot weapons. You get one pencil of radiation for each copper bar you vaporize in the explosion. Hopefully you could put more than one copper bar around each warhead, but they would all have to be locked on and tracking simultaneously. The real problem with this approach is that Russian countermeasures will almost certainly be much less expensive than the sattelites, and the arms race is after all an economic struggle... Two of the suggested couter-measures are first the obvious anti-sattelite missile, to be fired minutes before your attack, or second a sort of umbrella that deploys in front of each of your missiles as it leaves the atmosphere. The MIT defense analysis group claims that there are as many as twenty different workable counter-measures. They also claim that we don't have the required tracking and pointing technology now to make the system workable. -- Web Ewell Princeton Univ.
