The large bomber is an interesting story. It was leaked to western intelligence in the early 50's who immediately gave it the fictitious name Tu-200 and we had it entering service. When the Tu-20 (Tu-95) was identified shortly afterwards this 'Tu-200' was immediately dismissed as, at best, a mis-identification of the Tu-20 or, at worst, a complete hoax.
It remained this way until after the end of the cold war when a lot of archive material became available and the following were revealed;
first there is this, a redesigned 6 engined derivative of the Tu-85 that dates from 1948 (there was an 8 engine version proposed as well) designed as 'Project 489'
This design then evolved into this one, still under the same number, it now has more highly swept wing and a fully glazed nose, but the tail is lower than on the Western created picture in my earlier post.
There were even some sketchy specs with the drawings, range was 'up to 12,430 miles' Span 183ft, MTOW 209,000lbs and powerplants were to be 6 x Shvetsov ASh-73TK turboprops.
