Launch and Recovery is for two Space Shuttle launches, at $400 million each, including various related expenses. We'll probably not use the shuttle for most of the mass, as it's expensive and there's a rule against launching cryogenic fuels, but it works for the cost figures and a cheaper launcher will only make the numbers look better.
