I'd heard of this plane before but had never seen it, at least to my memory...
The idea is that the laser on the nose of that 747 identifies and shoots down incoming missiles. Sounds unlikely, but I think it's had more success than the old "Star Wars" SDI. The presence of this beast was loudly pointed out when the North Koreans ran their last missile test; as if to say, go ahead and try it Il, we'll have a test of our own to carry out.
And at the link there is a pic of something it has actually shot down. Just do not look into the laser with your exposed eyeball, or you'll find your entire head exploding.
