Didn't I read recently that North Korea was going to begin testing some missiles again? If one of those goes over Japan again, I'd expect to see one of the B-2's over the launch site...HUH?
The base at Guam is close enough to North Korea that they are well within range of the Taepo Dong 2 missile, but still far enough away that they can get most of the craft in the air before Andersen AFB would get hit. If that is the intent, my intuition tells me that a portion of the craft will be in air, around the base vicinity, at all times, to reduce the time needed to get all the craft in the air in the event of a NK first strike. If that is the case, than North Korea will become a sandlot within several hours...
