TsKB-57, S.V.Ilyushin

Another prototype of the single-seat Il-2. Original Ilyushin scheme (TsKB-55 with rear gunner position was rejected by Kliment Voroshilov (Stalin's favorite, hero of Civil War, proved himself as a military impotent during early dramatic stages of the Great Patriotic War). Moreover, Stalin and Voroshilov decided to make it single-seat bomber, capable to penetrate deep into enemy territory at higher altitude. They and other military leaders could never imagine that there will be no fighters available for escort...
|
As a result ten pre-production two-seaters BSh-2 were never delivered.
New TsKB-57 prototype had same 4 ShKAS in the wings, as the TsKB-55, and additional 155 liter fuel tank (in gunner's position). Aircraft became a testbed for new AM-38 engine, used for factory tests only.
One built.
