Design and Development
The Dornier Do.24 was designed to meet a Dutch navy requirement for a replacement of the Dornier Wals being used in the Dutch East Indies. It was an all-metal monoplane with a broad-beamed hull and stabilising sponsons. The aircraft was powered by three wing-mounted radial engines. The first two aircraft built were fitted with 447 kW (600 hp) Junkers Jumo 205C diesel engines. The next two had 652 kW (875 hp) Wright R-1820-F52 Cyclones, this was to meet a Dutch requirement to use the same engines as the Martin 139. The third aircraft (with Cyclone engines) was the first to fly on 3 July 1937. Six Dutch aircraft (designated Do 24K-1) were built in Germany, followed by a further aircraft built under licence by Aviolanda in the Netherlands (designated Do.24K-2).
Only 25 aircraft had been built on the Aviolanda assembly line before the German occupation. The Luftwaffe were interested in the completed and partially completed aircraft. The Dutch production line continued to produce aircraft under German control. 11 airframes were completed with Dutch-bought Wright Cyclone engines, but later models used the BMW Bramo 323R-2. A further 159 Do.24s were built in the Netherlands during the occupation, most under the designation Do.24T-1.
Another production line for the Do.24 was established in the old CAMS factory at Sartrouville, France, during the German occupation. This line was operated by SNCAN and was able to produce another 48 Do.24s. After the liberation, this facility produced a further 40 Do.24s, which served with the French Navy until 1952.

“I begin with a design for a hearse.
For Christ’s sake not black—
nor white either—and not polished!
Let it be weathered—like a farm wagon—”

“Fascism, the more it considers and observes the future and the development of humanity, quite apart from political considerations of the moment, believes neither in the possibility nor the utility of perpetual peace.”
