I also don't know what type of terminal maneuvers the Tomahawk can do and what kind of kinetics you get compared to an air dropped weapon, whether there is a penetrator option or not.
Personally, I can't see how AV8-B's got into the mix with their maintenance record at the same time they are using B-2s. If you want some air power in there why not bring a carrier. They can surge 100 sorties a day for a while and fly 60 sorties without really breaking a sweat.
