The Emergency Fighter Program (EFP) was begun in July of 1944 by the German Luftwaffe to help produce efficient and effective fighters to combat the growing threat of enemy bombers wreaking havoc on German war-making infrastructure. This produced a myriad of "paper" airplanes, wind tunnel models, and mockups though very few of the designs would ever actually see the light of day before the end. Messerschmitt remained a key contributor to Luftwaffe interests throughout the war - having delivered its important Bf 109 piston-driven fighter before the war - though they were never to repeat success after the arrival of their famous Me 262 "Schwalbe" jet powered fighter.
The P.1110 was one of the company's many late wartime projects and a submission for consideration into the EFP. This aircraft was designed as a high-altitude interceptor with propulsion provided for by a single turbojet engine. It featured swept wing surfaces (the mainplanes low-mounted) and a well-streamlined fuselage with twin intake ducts aspirating the Heinkel HeS 011A powerplant of 2,866lb thrust within. The jet would exhaust through a single ring at the base of the tail unit. The tail unit would have carried a single tail fin with low-set horizontal planes.
By early 1945, the primary threat on German radars was becoming the new Boeing B-29 "Superfortress", the sleek successor to the famous B-17 "Flying Fortress" and capable of carrying a greater war load at higher altitudes and to far greater ranges. While the "People's Fighter", the Heinkel He 162 single-seat, single-engine jet fighter had already taken root in the Luftwaffe inventory, this design was already of an older generation of jets despite its advanced form and a new, all-modern interceptor solution was sought. The P.1110 joined other Messerschmitt designs in attempting to satisfy the new Luftwaffe requirement.
Messerschmitt engineers estimated maximum speed at approximately 630 miles per hour thanks to its sleek design, swept surfaces and contoured intakes (no other numbers were available). Dimensions were to include a length of 30.7 feet, a wingspan of 27 feet and a height of 8.8 feet. Projected armament was to be 3 x 30mm MK 108 series autocannons fitted to the nose for a hefty punch against the most stubborn of enemy bombers. The aircraft would require only a single pilot and this person set under a simplified two-piece canopy with little framing to obstruct all-around vision. Overall construction was to use as much wood as possible due to limitations in raw war materials - particularly metal. The undercarriage was an all-wheeled, retractable tricycle arrangement.
Despite the seemingly impressive nature of the design, the aircraft was not selected by German authorities for further work (this honor fell to the intriguing Junkers EF 128 pseudo-flying wing interceptor). During the design stage, Messerschmitt also developed its aircraft along several slightly different lines - the P.1110/II was to feature a unique "ring-shaped" intake design aft of the cockpit as well as a V-shaped tail arrangement while the Me P.1110 "Ente" ("Duck") was given something of a complete rewrite - its cockpit was moved forward to take up the entire nose and small wing foreplanes (canards) fitted ahead of standard mainplanes aft. None of these additional products was given much steam before the German surrender of 1945.
