The innovative design of the Me P.1111 was completed in January 1945, and was intended as an improvement to the Messerschmitt P.1110 Ente.

[1] The Messerschmitt P.1111 was an 8.92 m-long tailless airplane with nearly delta-shaped wings, swept back at a 45-degree angle, and a wingspan of 9.12 m.[2] It was equipped with a pressurized cockpit for a single pilot.

The planned powerplant was a Heinkel HeS 011 turbojet engine, and armament was to be four 30 mm MK 108 cannon.

During a design review comparison conference in Oberammergau on February 27 and 28, 1945, the P. 1111 fared outstanding in the area of performance in high-speed flight capability, take-off, climb and landing performance.

The experts held the opinion that these qualities demonstrated a fundamental superiority of the flying wing construction type.
