Of course, given the Tu-16 still has some Tu-4/B-29 heritage...what about an American version...maybe as a low risk Boeing alternative to their B-47...just in case it didn't work out?
Sorta: "What if the Americans got the Junkers design team and their EF 132 design and not Soviets?"
I don't know whether Tupolev actually used the Junkers design, but the overall layout of the EF 132 looks pretty similar to the Tu-16's.
SOURCESo, a B-29 with swept wings and the jet engines buried in the wing root?
Would look a lot like tc2324's Tu-90:
LINKIf you want to change the engines to Western ones (as per Empty Handed's comment), maybe three in a row as on the EF 132, or, a little weirder, the inner two over-under and a third one next to them.
