In the beginning of 30s it was appeared in the world an idea of high-speed bomber that could outstrip contemporary fighters. One of the objectifications of this conception became the twin-engine bomber He 111 designed by a German Heinkel Flugzeugwerke AG company.
Since the May of 1941 it were produced He 111H-6 planes with liquid-cooled Jumo 211F-2 engines of increased power, with VS 11 wooden wider horde propellers and more powerful armament. This variant could carry SC 1800 kg bombs or two LT F5b torpedoes externally.
The He 111H-6 was the most produced variant of Heinkel’s medium bomber. It were produced approximately 1800 aircraft up to the end of 1942. He 111H-6s saw service on all fronts as level bombers, torpedo bombers, reconnaissance aircraft, transports, and mine layers.
