Soviet Tupolev Tu-4 bomber. Reverse engineered copy of the B-29.
During the war a few Boeing B-29s inadvertently landed in the Soviet Union after bombing missions over Japan. After the war the US demanded the aircraft back but the Soviets refused. Stalin ordered Tupoloev to copy the aircraft exactly.
The Tu-95 long range strategic bomber was a development of the Tu-85 which was born from the Tu-4 bomber.
