Hansa-Brandenburg W.17

The Hansa-Brandenburg W.17 was a German flying boat fighter of the World War I era, designed and built by Hansa-Brandenburg.

Design and development
Two W.17 prototypes were built for the Austro-Hungarian Navy. The first prototype (A49/I) was a biplane with a cantilever lower wing, while the second prototype (A 49/II) was a triplane with interplane bracing struts. Armament consisted of two 8 mm Schwarzlose machine guns. Gottfried Banfield, who oversaw evaluation of the W.17, judged the aircraft unsuitable for service due to its poor maneuverability. The second W.17, meanwhile, was evaluated by the Austro-Hungarian Navy in July 1917 but was not ordered into production.
