Seems that the JASSM is very cheap and there are multiple different warheads in development, including a bunker buster and different submutions.
The range is also going to be improved to

Very impressive weapon, can see why our airforce has the hots for it, hope that the deal goes through.

Though this might piss of the Russians a lot..
