It appears that there are significant delays with thebomb rack for the Massive Ordinance Penetrator (MOP).

Cost has increased 33%, and the delay is expected to be at least 10 months.

Considering the controversy over the weapon, Congress blocked funding to integrate it into the B-2, because of concerns that the Bush administration would use it on a surprise sneak attack against Iran, one wonders if the military might be dragging its heels until the crazies have left the White House.
