Based on the Boeing B-29 Superfortress (examples of which had made emergency landings in Russia during 1944 in the course of operations against Japan), the Tupolev Tu-4 differed in its armament and powerplant. It was a heavier aircraft and did not possess either the pressurised tunnel linking the forward to midships crew locations or the integral fuel tankage of the B-29. The first of a 20-aircraft pre-production batch flew on 3 July 1947. Series production terminated after over 400 aircraft had been delivered in 1952, by which time the Tu-4 was in large scale service with the Soviet DA (Long-Range Aviation), being accorded the NATO reporting name 'Bull'. Some were used as wingtip-to-wingtip inflight-refuelling tankers, others as conventional HDU-equipped tankers. The type was exported to China where some were re-engined with Ivchenko AI-20 turboprops and were sporadically used into the 1990s as AEW and drone launching platforms.

when they copied the B-29 they also copied all the bugs and weaknesses of it which it had many as it was rushed into production so quickly
Would be neat if we could somehow buy an old TU-4 from the Russians and fix it up as a flying B-29 back here in the States.

There is no doubt that the Tu-4 is a direct copy of a B29, the text above states as much. But what was copied was quite superficial. This plane does not hold a candle to the original. The aerostructure was quite different being manufactured from thicker guage lower quality metal. The overall performance was nowhere near the same, and as is usually the case when the Russkies copy something it never quite turns out as it should. The Tu160 Blackjack is a larger copy of the "Bone", is it better? No way, and in view of the fact that they only built 60 of them I think even the Russians would agree.
The Stupid Russians STOLE this from the U.S. This is a B-29 There own designs were so bad they had to uce the U.S.'s
It was a reverese engineered B29 copied from interned aircraft that made emergency landings in Manchuria following raids on Japan.

The Tu-4 is my most favorite Russain plane. The only thing I DONT like about it is that they totallly COPIED it from the B-29. JUST LOOK AT IT!! XD
Un problema fue que los soviéticos usaban sistema metrico y todas ls dimensiones del B-29 estaban en sistema imperial (pies, pulgadas) por lo que la URSS debio cambiar en varias fabricas a este ultimo sistema.
Otros cambios eran tanques de combustible e goma flexible en lugar de los integrales del B-29 y la supresion de las zonas presurizadas atras de la cabina de vuelo, incluso creo que sacaron el tunel presurizado.

Sergio, parecian muy semejantes en los exteriores, y la estructura era lo mismo, mas o menos, pero existian muchas diferencias pequenas entre los aviones (y no pequenas, por ejemplo, el armamento defensivo en el B-29 consistia de 12.7 mm ametralladoras, pero en los ejemplos definitivos del Tu-4, el armamento era 23 mm canones). Tambien el piel era diferente - era mas grueso en el Tu-4.
