By the end of WW2 several Boeing B-29s had to divert to Vladivostok during combat actions against Japan; they were never returned by the Russians. Instead Tupolev developed the Tu-4, which is seen here in an AEW version
This was one of the relatively few aircraft at Datangshan for which it was easy to get a nice side on shot. Nevertheless, I picked this one out as it shows off nicely the unusual lines of this magnificent aircraft. Note turboprops have replaced the piston engines present on the B-29 original.
Toward the end of WWII, the Soviet Union saw the need for, but lacked completely, a strategic bombing capability similar to that of the USAAF. On four occasions during 1944, B-29s made emergency landings in Soviet territory after bombing Japan. Three repairable B-29s were flown to Moscow and delivered to the Tupolev OKB enabling reverse-engineered copies to be produced in less than two years. This example is on display at the Central Museum of the Air Forces at Monino.
An extraordinary machine by any standard. In 1967, China attempted to develop its first AEW platform based on the Tu-4 airframe with AI-20 turboprop engines. The project was named KJ-1, with a Type 843 rotor-dome on top. However, the equipment was too heavy and failed to meet PLAAF requirements so the project was cancelled in 1971
