|Quoting KC135TopBoom (Reply 1):|
I don't think the USAF has any plans, or money to reengine the B-52H or E-3B/C. They might be able to reengine the KC-135E with F-108s, but even that doesn't look good, from a budget position (and they think they can afford a new tanker, anyway).

Those KC-135s are not that long for this world, as soon as they can figure out what to replace them with. Why re-engine them if they are going?
