DB-4
The Ilyushin DB-4 (DB - Дальний бомбардировщик - Dalniy Bombardirovshchik - long-range bomber) or TsKB-56 (TsKB - Tsentral'noye Konstruktorskoye Byuro - central construction bureau) was a Soviet twin-engined bomber aircraft of the early 1940s. It was a development of the Ilyushin DB-3 and was intended as a replacement for the earlier aircraft, but only two prototypes were built; engine problems and the need to concentrate production on existing types following the German invasion of the Soviet Union in June 1941 meant that no more examples were built.
