What the heck do we need this for? We pretty much won the cold war. Who are we suppose to nuke now? An alien invasion scenario? Granted there are terrorists, but this is sort of way overkill for them. I cannot even see using it, in case some terrorist group was to sieze a nuclear missile compex in the former Soviet Union. What are they going to do, drop a 1 megaton nuke on a missile complex in another country to wipe out some terrorists?

Of course the idea and concept is good. A vehicle like this would enter the atmosphere not using engines, thus it would be harder to detect. It's on a hypersonic "dead stick landing" approach. he vehicle is a great step towards highperformance autonomous aircraft.

My question is why not go to a sub-light-speed inertial weapon. if you have a 2,000+ pound iron object travelling 60,000+ mph on impact, who needs nukes? Same nuclear bomb effect, no toxic radiation problems. Plus it's a lot simpler. they could park them in orbit way up there and just fire them off when needed. Virtually undetectable until they hit the atmosphere and you see the streak, but it's too late then.
