Well I doubt it - though Tomahawks ain’t cheap ($1 million each or there abouts.) What a B2 CAN do that a tomahawk can’t is to be retargeted, or take care of targets of opportunity.
There are reasons to use it over other weapons systems. The other simple fact is that the military has never been great at cost savings... that isn’t what they are for ;-) Their job is to kill people and break things in an efficient, violent manner.
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.
If I was Qadaffi I would make a play at hitting Sicily with just a couple bombs. That would bring this whole thing to a screeching halt.
The Block IV's can! If I remember correctly, the rebuilt Ohio boomers(the Florida, Georgia, Michigan and Ohio) are fully populated with 'em. They can be launched untargeted and tasked by the Seal teams that have infiltrated the country from the sub. They also have a loiter mode while they await tasking.
From Navy.mil: " Tomahawk Block IV (TLAM-E) is the latest improvement to the Tomahawk missile family. Block IV capability enhancements include: (a) increased flexibility utilizing two-way satellite communications to reprogram the missile in-flight to a new aimpoint or new preplanned mission, send a new mission to the missile en route to a new target, and missile health and status messages during the flight; (b) increased responsiveness with faster launch timelines, mission planning capability aboard the launch platform, loiter capability in the area of emerging targets, the ability to provide battle damage indication in the target area, and the capability to provide a single-frame image of the target or other areas of interest along the missile flight path; and (c) improved affordability with a production cost of a Block IV significantly lower than the cost of a new Block III and a 15-year Block IV recertification interval compared to the eight-year interval for Block III."
All this at a cost of $569,000 per copy.
Not quite true.
Raytheon has delivered 2000 Block IV tomahawks that can be re-targeted in flight -
Tomahawk Block IV’s technologies provide a tactical capability while reducing acquisition, operation and support costs. It employs a two-way satellite datalink that enables a strike controller to flex the missile in flight to preprogrammed alternate targets or to redirect it to a new target. This targeting flexibility includes the capability to loiter over the battlefield and await a more critical target
