Description from luft46.com:
"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. On the third design, the P.1068.01-83, the wings and fuselage were reduced in size in order to increase the speed but keeping the same payload. Of course, the smaller fuselage meant a reduced fuel supply, and so the range was less than the first design's (He P.1068.01-78). Four He S 011 turbojets located on the leading edge of the wing were to provide the power. Remote controlled, rear firing armament was included with this design also. However, the aircraft was lighter by four metric tons, which was of a benefit given Germany's scarcity of raw materials at this stage in the war."
