The Messerschmitt P.1112 was a proposed German jet fighter, developed by Messerschmitt AG during the closing stages of World War II, and intended for use by the Luftwaffe. The progress of the war prevented the completion of a prototype before the fall of Nazi Germany. Its design, however, had a direct influence on post-war US Navy carrier fighters.[3]

Design and development[edit]

The work on the Me P.1112 started on 25 February 1945 after Willy Messerschmitt decided to halt the development of the Messerschmitt P.1111 that would have required as standard equipment a pressurized cockpit and ejection seat.[4][5] Designed by the head of the Messerschmitt Project Office Woldemar Voigt (1907–1980), between 3 and 30 March 1945 as an alternative to the Me P.1111, the Me P.1112 design was less radical than P.1111's and incorporated the lessons learned from the development of the Messerschmitt P.1110 design.[2][4][6] Voigt estimated that the Me P.1112 would commence flight testing by mid-1946.[3]

Intended to be powered by a single Heinkel HeS 011 turbojet, three design concepts of the Me P.1112 were developed.[5] The last proposed design was the Me P.1112/V1 using a V-tail design and fuselage lateral intakes; the two first were the Me P.1112 S/1, with wingroot air intakes, and the Me P.1112 S/2, with fuselage lateral intakes, both with a larger, single fin; both designs lacked conventional horizontal stabilizers. All three had a fuselage maximum diameter of 1.1 metres (3 ft 7.307 in).[7] The aircraft's wing design was similar in appearance to that of Messerschmitt's Me 163 Komet rocket fighter. The pilot was seated in a semi-reclined position, and was equipped with an ejection seat.[6]

A partial mockup of the Me P.1112 V/1,[8] consisting of the aircraft's forwards fuselage section, was constructed in the "Conrad von Hötzendorf" Kaserne at Oberammergau, but the Messerschmitt facilities there were occupied by American troops in April 1945, before construction of the prototype could begin.[6][9]

Although the Me P.1112 was never completed, follow-on designs were already proposed even as design work on the type itself was done. These included a proposed night fighter version, which was intended to be fitted with twin engines mounted in the wing roots of the aircraft.[6]

Following the war, Voigt's experience in tailless aircraft design was put to use by the Chance Vought company in the United States, where he was involved in the design of the F7U Cutlass fighter.[6]

Notes[edit]

  1. ^ a b The P 1112/V1 design of 30 March 1945 had an overall length of 9.24 m (30 ft 4 in) and a span of 8.16 m (26 ft 9 in).[8]

  3. ^ The long-barreled Mauser MK214 50mm cannon was developed in an effort to create the ultimate bomber-killers, capable of attacking from a long distance, protected from the defensive fire of the bombers. A MK 214 mounted on a Me 262 was used only time against American bombers on 16 April 1945 by the special fighter unit Jagdverband 44 (Forsyth 2008, p. 62; Jenkins 1996, p. 48). The MK 214 was planned to be mounted asymmetrically on the P1112 front, necessitating an asymmetric seating (Griehl 1988, p. 86).
