The Heinkel He 343 was a quadjet bomber project developed by Ernst Heinkel Flugzeugwerke in Nazi Germany during the final two years of World War II. Plans recovered by the Soviet Union were studied and used in the development of the Ilyushin Il-22.

Design and development

The Heinkel He 343 was designed for the Luftwaffe by the German Heinkel aircraft manufacturing company in the beginning of 1944. Twenty were ordered. To shorten development time and allow existing parts to be used, its design resembled the Arado Ar 234. Engines were to be the Junkers Jumo 004 and Heinkel HeS 011.

The DFS named the project P.1068. By late 1944, Heinkel engineers had nearly finished building parts for the He 343 prototype when the order was cancelled due to the Emergency Fighter Program.

Four versions were planned: the A-1 bomber, the A-2 reconnaissance aircraft, and the A-3 and B-1 Zerstörer ("Destroyer") heavy fighters.

Postwar, the Soviet Union utilized the design as the basis for the development of the Ilyushin Il-22, changing some of the parameters such as size and crew numbers. One prototype was built and flown.[1][2] The results of the tests were used in development of the Ilyushin Il-28.
