Gotha WD.8
German reconnaissance floatplane World War I, 1915
From Wikipedia, the free encyclopedia
The Gotha WD.8 (Wasser Doppeldecker - "Water Biplane") was a single-engine maritime patrol floatplane developed during World War I by Gothaer Waggonfabrik for the Imperial German Navy's (Kaiserliche Marine) Naval Air Service (Marine-Fliegerabteilung). The WD.8 was a single-engine version of the WD.7 developed for comparative purposes. The single prototype built was deemed "totally unsuitable" by the Naval Air Service and was later sold to the Ottoman Empire.

Design and description
The airframe of the WD.7 was used to create the WD.8 reconnaissance floatplane, substituting a single water-cooled 240-horsepower (180 kW) Maybach Mb.IVa straight-six engine in the nose for the two wing-mounted 120-horsepower (89 kW) engines of the earlier aircraft.
