Background
The Douglas A-20 is a United States three-man crew, twin-engined bomber of World War II. Its main role being a light bomber/attack aircraft, it was also used for intruder operations and for reconnaissance. The A-20 was developed and manufactured by the Douglas Aircraft Co. first as the Douglas DB-7, with multiple other variants made during its production years (1939-1944). Of the 7478(or 7385) aircraft produced 2908 were sent to the Soviet Union.

The A-20C was an attempt to develop a standard, international version of the DB-7/A-20/Boston, produced from 1941. It reverted to the slanting nose glass, and it had RF-2600-23 engines, self-sealing fuel tanks, and additional protective armor.
