Why don’t they just build some new ones?............
Look at what happened to the F-35: Late, massively overbudget, and with questions about its effectiveness. Politicians divvied it up to make sure that every district or state got part of the contract.
No translate that to something like a B-52 replacement!
That is why the BUF is still in service after 66 years. It’s here. It works. It’s paid for.
Sometime back in the ‘90s, there was an airshow at Andrews AFB, and they had a B-52 on display. Its bomb bays were open, and as I walked underneath I looked up and saw motors with aluminum name plates and a crinkled black finish and bundles of wires with cloth covering. I guess it all worked fine, but it was definitely from the ‘50s.
Can you imagine how that would go? By the time the AF generals got their say-so, then the house and senate to approve the funding, it would cost 10’s of billion$ per plane and then they would scrap it because it wasn’t all electric to meet the green goals of Congress
I find the B-52s very attractive.
And no, I'm not talking about a dance band out of Athens, GA.

We no longer have any manufacturing base, and China refused to do it for us...
