Not satisfied that the F-35 will bankrupt the US and military, the Air Force ups the ante with a program projected to cost $60 Billion.
Wait for it; next will be the selection of the T-50 to replace the T-38 instead of a cheaper and more practical airplane for UPT (like the L-159).
B-52: bomb-truck; lots of bombs and loiter.
B-1: conventional-only; not a bad bomb-truck, but fewer bombs, less loiter, more expense.
B-2: in theory both conv and nuke. Limited conventional bombs; rumored to cost more than $100,000 an hour.
Yup....B-21 makes perfect sense....
