I think of a D5 as a Trident missile. Shoots up into low earth orbit and travels round the earth at Mach 15 dropping multiple independent moabs on enemy targets. Doesn't rely on GPS but instead shoots the stars to get a fix and goes on it's merry way knocking the living fuck out of all enemy targets on an unstoppable frenzy of destruction. I think when the D5 drops we'll all know about it, but doubt it's today
