The correct answer is the Arado Ar E.581.4. In 1943, Arado began a work on the Ar E.555 Amerika-bomber project. This flying wing configuration was thought to be the best design to meet the requirements of high speed, heavy load-lifting and long-range aviation. Due to the design acceptance by the Reichsluftfahrt Ministerium (State Ministry for Aviation) in early 1944, the Arado design team scaled down the same configuration to design a smaller size fighter version, the Ar E.581-4. It was a single-seat fighter powered by the single HeS011 turbojet engine. The delta wing with the twin fins were based on the same design as the Ar E.555 bomber. In the fall of 1944, the Reich had been depleted of design resources and concentrated their facilities on the production of existing fighters. Arado was ordered to stop all the new projects, which included the Ar E.581-4 fighter.
