The DB-240 retained little apart from the general layout of the Stal-7 as the structure was almost completely redesigned. The pilot's cockpit was offset to port to improve his downward view and the navigator/bomb aimer sat in the extensively glazed nose with a 7.62-millimeter (0.300 in) 595: 666: 258: — "Factory for Special Constructions at the Scientific Test Institute for the Civil Air Fleet"). The performance of the Stal-7 was exceptional, particularly in respect to its payload: at gross overload weight over 56% of the total weight was payload. During flight trials with maximum all-up weight the prototype crashed on takeoff in early 1938, resulting in the arrest of Bartini and his imprisonment in a 325:

However, these did not offset its virtues of a heavy bomb load and long-range (4,100 kilometers (2,548 mi) carrying 1,000 kg (2,205 lb) of bombs). It was ordered into production at Factory No. 18, in

The DB-240 prototype flew for the first time on 14 May 1940 and began its State acceptance tests on 27 September 1940. The weaker engines prevented the DB-240 from reaching its designed performance. It could only attain 445 km/h (277 mph) at 4,250 m (13,944 ft) instead of the
