Messerschmitt M 22

The Messerschmitt M 22, also called the BFW M.22, was a twin-engined medium bomber designed by Willy Messerschmitt for the German Ministry of Transport. It was the second of the only two biplanes Messerschmitt ever designed, both unsuccessful, and it came out of the 1927 arrangement under which he joined BFW and the Ministry pressed him to build military aircraft. The biplane had broad-chord I-form interplane struts, ailerons on both wings, an externally braced tailplane, and an upper wing raised on a long faired pylon that separated the pilot's cockpit and nose gunner from a dorsal gunner. Two 500 hp Siemens-built Bristol Jupiter radials, designated Sh-20 or Sh-21, were mounted between the wings. It first flew in 1928, was very different from Messerschmitt's trademark high-wing monoplanes, and received no production order, so only one was built.
