A MOAB is a “get close” weapon.
MOP is a precise weapon that needs release cues other than a grease pencil mark on a windscreen.
Right now, the B-52 is the option, with B-2’s coming along.
Strike packages are many aircraft to support a mission, not a single aircraft.
MOP is GPS guided, with control fins. It can be rolled out the back of any cargo aircraft that can lift it to drop altitude and still score a precision hit.
You have a great Fourth too!
