Boeing B-50D Superfortress - "Not Quite Ultrafortress"

I want this

+1 yes final refinement of aircraft are cool B-50D though only slightly better would be fun to see as the final push of the design

This could also be added as a nuclear bomber to replace the B-29 as a more equal aircraft to the TU-4, which is much better due to its better guns. At least the B-50 would be faster and slightly better armed than the B-29 (maybe keep the B-29 as a 5.7-6.7 lineup exclusive if you want to keep it in some form)

It’s still .50 cal M2 MGs, though.
