This tailless plane was developed in 1944, when in Germany there were already jet aircraft in production. The decision to fit a conventional engine to the aircraft was made because the existing jet engines had not yet reached the desired performance. Thus the project went ahead in such a way that the design could be re-fitted with a jet engine when the technical difficulties were solved, eventually leading to the Blohm & Voss P 212 jet aircraft project. The engine was fitted at the back of the cockpit with the propeller pushing the plane forward. The tail unit was incorporated into the swept wings, which provided an improved performance. In order to withstand the added stress the wings had steel reinforcements. Three different variants of the plane were designed. All had a retractable tricycle landing gear. **** UPDATED**** Improved stability American Airforce Version / 4 blade prop / tail installation
