The future is now... Of course, it has the same drawback as Patriot - it's a point-defense system. The kill of the target means that the intended target of the "kill" isn't hit - but that armed-and-still-full-of-explosive warhead is going to head to earth ballistically, where it will detonate or become an UXO hazard. It's not going to hit what it was aimed at - but it will hit something. Like a warehouse, full of troops, perhaps, for those who remember Gulf War I. Not an argument...
