The Air Force has a 'new and shiny' problem.
When you get something that works, you might make minor upgrades, but in general, the design stays the same.
The A-10, for example, in the CAS role.
The BUFF is another aircraft that is well designed, and is being flown by the grandsons of those who first took them into the air, a long string of updates and upgrades ago.
And still the more basic roles are being filled worldwide by aircraft that are old enough to sign up for Medicare. DC3s, C-47s and others still in service, still getting the job done. Why? because when you have achieved an optimal design, it's hard to improve on that.
The C-130 entered service the year i was born and is still a go-to aircraft for a wide variety of support and even offensive missions.
Build what works. Build a lot of them, that way the development costs are amortized across a large fleet, and the per unit price comes down.
As for the B-2, let our enemies sweat every flock of geese on the radar and wonder.
