The innovative design of the Me P.1111 was completed in January 1945, and was intended as an improvement to the Messerschmitt P.1110Ente.
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. It was equipped with a pressurized cockpit for a single pilot. The planned powerplant was a Heinkel HeS 011turbojet engine, and armament was to be four 30 mm MK 108 cannon.
Only one wooden model was built. The project was later further developed into the Me P.1112.
