The Ilyushin IL-4 (originally designated DB-3F) was a Soviet long-range bomber and torpedo bomber that served as one of the primary strategic bombers of the Soviet Air Force during World War II.
Development
The IL-4 was a development of the earlier DB-3, designed by Sergei Ilyushin's bureau. The redesigned aircraft featured an improved fuselage, more powerful engines, and better defensive armament. It entered service in 1940 and quickly became one of the most important Soviet bombers.
Operational Service
The IL-4 served in multiple roles during the Great Patriotic War. It was used for long-range strategic bombing, including raids on Berlin and other German cities in the early months of the war. The aircraft also served as a torpedo bomber with Soviet naval aviation, attacking Axis shipping in the Baltic, Black Sea, and Arctic.
The IL-4 was notable for conducting the first Soviet bombing raid on Berlin on the night of August 7–8, 1941, just weeks after the German invasion. These early raids, while causing little physical damage, had significant propaganda value.
