I assume (hope) its the entire program cost.
Wikipedia (ha ha ha) has an interesting article. FWIW. We've probably spent more than $1trillion on the entire program, by now, including operations and maintenance. Flying is expensive; JP8 isn't cheap. I'm not arguing that the program has been well run, or that we're getting our money's worth ... that's a big discussion. But some folks, including possibly the author of the OP, have displayed a nasty habit of misrepresenting DOD program costs, and if one doesn't read carefully one can be led to believe things that aren't true.
