could HARPP be an EMP defence shield?

it could be a defence shield against EMP weapons? so non one country could launch a surprise nuke attack.

Very possible. I wonder whats it purpose sitting way up there out in the middle of nowhere? It could be just for that fact that the U.S. has tried to hedge it's bets and forsaw the need for this system. Other than that, the door is wide open and I'm quite sure there are more here that would know more than I on this subject.

Hmmm..good point. Although its got many uses that could be the main one. Very possible...

Or is it a secretive missile defense shield? Maybe it heats up the ions in the air to superheated conditions so that the missle would burn up and fall apart. Or maybe this is a crazy theory?

If a missile containing a nuclear warhead burnt up and fell apart upon entry wouldn't that be just as bad if not worse than if it just detonated??

I mean, if it blew apart up there wouldn't the radioactivity be unconrollable and spread a greater distance?
