Both Dornier and Junkers were competitors for the contract, and each received an order for three prototypes in late 1935. The Dornier design was given the project number Do 19, while the Junkers prototype became the

The V1 prototype flew on 28 October 1936. After ''Generalleutnant'' Wever died in an airplane crash on 3 June 1936, the heavy bomber program lost its momentum, and never recovered. When the ''Luftwaffe'' was given its heavy blow over the skies of England, the error of not having heavy bombers became apparent. By then, however, it was too late to develop the bombers required.
Albert Kesselring, Wever's successor, believed that what Germany required were more
fighters and tactical bombers.
Also Kesselring and Jeschonnek had suggested to Göring that it would be better to drop heavy bomber projects due to material shortages. Around 2.5 tactical bombers could be built with the same material as one heavy bomber. In May 1937 Göring is reported as saying to Milch ‘The Führer does not ask me how big my bombers are, but how many there are’

Therefore, the V2 and V3 prototypes were scrapped. The original V1 became a transport in 1938. The Dornier Do 19 had a disappointing performance: it was slow, carried only a 1,600 kg bombload, and had only medium range. In fact, the whole Ural bomber concept had already been abandoned, not only because the required range was impossible, but also because existing navigation and bombsights were not up to the task.
