The Messerschmitt Me 328 was a prototype pulsejet-powered fighter aircraft designed and produced by the German aircraft manufacturer Messerschmitt AG. The Me 328 was originally designed as the P.1073 in 1941, having been envisioned as a parasite aircraft that would protect Luftwaffe bomber formations from Allied fighter aircraft. Being largely composed of wood, the Me 328 was forecast to be several times cheaper than the cost of traditional German fighter aircraft, such as the Focke-Wulf Fw 190 or Bf 109. It was proposed to use various forms of propulsion, including a single Jumo 004 turbojet engine, either two or four Argus As 014 pulsejets (as used on the V-1 flying bomb), and even as an unpowered glider. The Deutsche Forschungsanstalt für Segelflug (DFS - "German Research Institute for Sailplane Flight") was also involved in its development.
