Ilyushin Il-4

The Ilyushin Il-4 was a Soviet World War II bomber aircraft, widely used by the Soviet Air Force (VVS, Voenno-Vozdushnye Sily) although not well known. Its NATO code-name was Bob. 

The Il-4 started life as a quickly produced bomber prototype called the TsKB-26. It was put into production in 1936 as the DB-3. DB-3 was followed by the updated DB-3M ssing lessons learned from the Li-2 (Douglas DC-3). A change of engine resulted in the DB-3F, which was renamed in 1942 as the Il-4. 

Although the Il-4 was only a medium bomber, it had the range to be used on strategic missions. The Il-4 was used on several highly publicized raids against Berlin during the Second World War. Most were used on much shorter range missions.
