In 1943 Dornier evolved a series of studies in which a turbojet was fitted into the rear of the Do 335 instead of the normal piston engine. In mid 1944 it was decided to proceed with a mixed-power Do 335 adapted to a night fighter role. The RLM transferred development of this aeroplane to Heinkel because of that firms experience of jet engines and night fighters, plus that fact that they were to make the Do 335 B-6 night fighter at Oranienburg, replacing the He 219.

Designated He 535 the plane was to be fitted with ether standard wings or the newly designed laminar wings (by Dornier) and a much modified fuselage, to take the He S 011 engine and radar operator. The intakes being on each side of the aircraft mid point just behind the wing roots, a radar operator was located between these intakes just between the wing root and engine. A development contract was issued in January 1945, however no aircraft Oranienburg were completed by the war's end.
