The Hansa-Brandenburg KDW ("Kampf-Doppeldecker-Wasser") was a German naval aircraft during the First World War .
development
The designer of the Hansa and Brandenburgische Flugzeug-Werke Ernst Heinkel had the KDW - not to be confused with the flying boat Hansa-Brandenburg CC , which was also called KDW by the Austro-Hungarian Navy - in 1916 from the Hansa-Brandenburg DI fighter plane with the latter typical star strut, to which he attached floats and a caudal fin and whose wingspan he increased. To improve the pilot's view, the distance between the upper wing and fuselage had been increased, and small cutouts were made in the lower wing roots. At that time, the Imperial Navy was looking for a seaworthy single-seater fighter to secure its facilities against enemy air attacks.
A total of around 60 machines were built in five different production series by February 1918, each of which differed slightly from one another: The first machines were given the Benz Bz III engine, the following series Daimler engines Mercedes D IIIa , then the Bz III was used again. In the last series, the Maybach Mb III with 160 hp was installed. A variant W.11 with a 200 hp Benz Bz IV engine was also built with three copies. In addition, a W.16 with a 160 hp U.III rotary engine and a W.25 with conventionally braced wings were tested.
From mid-1916 the KDW operated mainly on the North Sea and the Adriatic Sea, where they remained in service until the end of the war. Nevertheless, the machine was already out of date in 1917 and inferior to the Albatros W.4 and the Hansa-Brandenburg W.12 .
