In terms of cost, I have no idea what the dollar figure is to stand it up. There's a maintenance cost to sustain just the capability, to make sure it's primed and ready to go. Once deployed in a real-world scenario, a lot of the materials would not be recovered, so I don't know about that aspect.
In terms of application for another interested party, I've never seen any interest in that sort of thing, so I can't answer you.
