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 last of the P.1068.01 designs was also the only one that featured a swept wing. The wing was swept back at 35 degrees, and four He S 011 jet engines were mounted along the fuselage, two in front and below the wings and two behind and above the wings. Although wind tunnel testing showed a marked improvement of flight handling at slower speeds and during landing (due to the engine arrangement), the swept wing version offered only a slight increase in speed over the other straight winged versions.
