I said it would be weeks instead of days, so 8 weeks would be about two months ... :-) ...
With 40 or less (nuke) targets (after complete Air Supremacy), flying 80 sorties a day with heavy bombers (easy for us), one has to ask how many bombs do you want to drop into the same hole?
Each heavy bomber can carry TWO, 30,000lb MOPs.
Or, 150,000lbs of conventional bombs.
