12/31/2012. Built in July 1915, the three-bay WD 3 (WD = Wasser-Doppeldecker, sea biplane), intended for bomber training and reconnaissance, had a central nacelle housing the 160 hp Daimier D.III engine, driving a pusher propeller. The observer sat in the extreme nose and was armed with a 0.312 in (7.92 mm) Parabellum machine gun; a radio transmitter was also installed. The aircraft had two tail booms, which were interconnected at the rear by the tail plane, on top of which was a third fin. Only one example was built, serialed 259.
