In 1942, the RLM contacted Junkers to design a four-engined jet bomber, which became the Ju 287. Meanwhile, Heinkel also did some design work on this specification. In June 1943, the RLM issued a different specification for a two seat bomber with a bombload of 2000 kg (4409 lbs) and a speed of  800 km/h (497 mph) over a range of 2500 km (1554 miles). Siegfried Günter of the Junkers Design Bureau in Vienna designed at least four versions of the P.1068 by the end of 1943. Some of this design work was later used for the Heinkel He 343.
          The first design, the P.1068.01-78, featured a mid-wing, slightly swept wing and Fowler flaps were planned to help minimize the landing speed. Four He S 011 jet engines were to be mounted individually along the wing leading edge, but since it was believed that the He S 011 engine would not be ready before mid-1945, the Jumo 004C turbojet could also be fitted. There were three fuel tanks located behind the cockpit that each held 1980 liters (523 gallons) and another fuel tank that held 4850 liters (1281 gallons). A bomb bay was located beneath the forward fuel containers. The main gear retracted to the rear into the fuselage, and the nose wheel retracted to the rear and rotated 90 degrees to fit beneath the pressurized cockpit, where a crew of two was accomodated. No defensive armament was planned at this stage.
