He 111Z-1 "Zwilling"
In the early 1930s, the idea of a high-speed bomber capable of outrunning modern fighters appeared in the world. One of the objectifications of this concept was the He 111 twin-engine bomber, developed by the German company Heinkel Flugzeugwerke AG. From May 1941, He 111H-6 aircraft were produced with liquid-cooled Jumo 211F-2 engines of increased power, with larger VS 11 wooden propellers and more powerful armament. The He 111H-6 was the most produced variant of the Heinkel medium bomber. Heinkel He 111Z-1 Zwilling (Gemini) – two He 111H-6s joined together by a new wing section on which a fifth engine is mounted. It was designed to tow an Me 321 or two Go 242 gliders. By the end of spring 1942, 12 aircraft had been built. The He 111Z-1 was used mainly on the Eastern Front as tow gliders and transport aircraft.
