As a defender, you only need to fail once. Blow up a few B-2s on the ramp and that becomes a event with unlimited bad potential.

By the time it takes the missiles to reach there, the planes could be in the air.

		Could be. But won't be. The flying time to target is mere minutes, and taking the plane from zero (not even crew inside) to air takes much longer than that.
