Dornier Do X

The Dornier Do X was the largest, heaviest, and most powerful flying boat in the world when it was produced by the Dornier company of Germany in 1929. First conceived by Dr. Claude Dornier in 1924, planning started in late 1925 and after over 240,000 work-hours it was completed in June 1929.

During the years between the two World Wars, only the Soviet Tupolev ANT-20 Maksim Gorki landplane of a few years later was physically larger, but at 53 metric tons maximum takeoff weight it was not as heavy as the Do X's 56 tonnes.

The Do X was financed by the German Transport Ministry and in order to circumvent conditions of the Treaty of Versailles, which forbade any aircraft exceeding set speed and range limits to be built by Germany after World War I, a specially designed plant was built at Altenrhein, on the Swiss portion of Lake Constance.

While the type was popular with the public, a lack of commercial interest and a number of non-fatal accidents prevented more than three examples from being built.

Dornier Do 217

The Dornier Do 217 was a bomber used by the German Luftwaffe during World War II as a more powerful version of the Dornier Do 17, known as the Fliegender Bleistift (German: "flying pencil"). Designed in 1937 and 1938 as a heavy bomber but not meant to be capable of the longer-range missions envisioned for the larger Heinkel He 177, the Do 217's design was refined during 1939 and production began in late 1940. It entered service in early 1941 and by the beginning of 1942 was available in significant numbers.

The Dornier Do 217 had a much larger bomb load capacity and had much greater range than the Do 17. In later variants, dive bombing and maritime strike capabilities using glide bombs were explored in depth, with considerable success in the latter role. Early Do 217 variants were more powerful than the contemporary Heinkel He 111 and Junkers Ju 88, having a greater speed, range and bomb load. Owing to this it was designated a heavy bomber rather than a medium bomber. The Do 217 served on all fronts in all roles. On the Eastern Front and Western Front it operated as a strategic bomber, torpedo bomber and reconnaissance aircraft. It also performed tactical functions, either direct ground assault or anti-shipping strikes during the Battle of the Atlantic and Battle of Normandy. The Do 217 was also converted to become a night fighter and saw considerable action in the Defence of the Reich campaign until the last day of the war.

Dornier Do J

The Dornier Do J Wal ("whale") was a twin-engine German flying boat of the 1920s designed by Dornier Flugzeugwerke. The Do J was designated the Do 16 by the Reich Air Ministry (RLM) under its aircraft designation system of 1933.

Design and development

The Do J had a high-mounted strut-braced monoplane wing with two piston engines mounted in tandem in a central nacelle above the wing; one engine drove a tractor and the other drove a pusher propeller. The Do J made its maiden flight on 6 November 1922. The flight, as well as most production until 1932, took place in Italy because of the restrictions on aviation in Germany after World War I under the terms of the Treaty of Versailles. Dornier began to produce the Wal in Germany in 1931; production went on until 1936.

In the military version (Militärwal in German), a crew of two to four rode in an open cockpit near the nose of the hull. There was one machine gun position in the bow in front of the cockpit and one or two amidships. Beginning with Spain, military versions were delivered to Argentina, Chile and the Netherlands for use in their colonies; examples were also sent to Yugoslavia, the Soviet Union and to the end of production Italy and Germany. The main military users, Spain and the Netherlands, manufactured their own versions under licence. Several countries, notably Italy, Norway, Portugal, Uruguay, Great Britain and Germany, employed the Wal for military tasks.
