You're right. My estimate is off by a bit over an order of magnitude for the f-22. they cost just under 50,000 an hour to operate (http://hatch.senate.gov/public/_files/USAFResponse.pdf) you could certainly operate more than 10 of them for 9 billion.

I think a B-2 will come close to that though. 1 billion in todays dollars and 130,000 an hour for operational costs. -it's not actually 2000 a minute, there's a bunch of work before and after each flight.
