I recognize that it was a proof of concept. I also know a B-2 is half the cost of a nuclear powered attack submarine, which has a much longer loiter time, much greater weapon capacity, a broader sensor suite, and lasts a lot longer. And it actually can't be found
And trust me...the Pentagon can absolutely put a price tag on aircrews

They do it all the time.
I was expecting more years out of the 117. That's not a long lifespan for that kind of dough. That's my point.
