Hansa-Brandenburg W.11

The Hansa-Brandenburg W.11 was a prototype floatplane fighter designed by the Hansa-Brandenburg Aircraft Company (Hansa Brandenburgische Flugzeugwerke) for the Imperial German Navy's (Kaiserliche Marine) Naval Air Service (Marine-Fliegerabteilung) during World War I. It was a slightly enlarged version of the KDW fitted with a more powerful engine. Only three examples were built during 1916 and no production order followed. Their activities are not known with any detail, but one survived to the end of the war and was probably scrapped afterward.
