The Dornier Do 19 was a German four-engine heavy bomber that first flew on October 28, 1936. Only one prototype flew, and it was converted to a transport in 1938. The other two were scrapped. The Luftwaffe had a shortcoming in the lack of an efficient heavy bomber fleet. Generalleutnant Walther Wever, the Luftwaffe's first Chief of Staff, was the most persistent advocate of a German long-range strategic bomber fleet. It was built for the Luftwaffe's Ural bomber program under General Walther Wever. The RLM Technisch Amt issued a specification for a four-engine heavy bomber. But after Wever's death in an airplane crash in June 1936, Wever's successor, Albert Kesselring, canceled Germany's long-range bomber projects to concentrate on tactical bombers.
