As a lot of LRMP work was indirect support searching the oceans well ahead of any surface, or subsurface, vessels then it was out of sight, out of mind.
I would guess that the "Air Plan 4 sectors 1 and 2" were carried out infrequently and even 10 miles from the force were out of sight. Those who were on Corporate probably missed the big picture and it will be a while before their successors notice the dark areas on the data link plots.
