I remember the concept from a few years back.
Primarily the concept is that of the Arsenal Ship. It carries the munitions and a Close Combat spotter crew either on the ground or in another aircraft actually pick out the target and guide the missiles or bombs into it.
The Arsenal ship, in this case a converted 747 freighter, would stand back out of the immediate combat area and release ordnance as directed. Plus the capability of a huge loiter time makes this an attractive idea for the military.
The only drawback I see is that the Air Force tends to Multi-role everything. I can just see some bright boy saying, “Well lets put in some extra fuel capability and we can do in-flight refueling, and since this was a freighter originally let’s use it for air transport. And we can carry troops and .....”
In a case like this I believe a single purpose role is best. Pick one and stick with it.
Next thing you know some hot shot bean counter would decide
it needed folding wings for carrier duty, and don’t forget
an arresting hook, a big one.
