Hansa-Brandenburg W.11 Explained

The Hansa-Brandenburg W.11 was a fighter floatplane built in Germany in 1917 as a more powerful version of the KDW. Similar in general configuration to its predecessor, the W.11 shared the same unusual interplane strut arrangement, and featured fins above and below the fuselage. Only three examples were built.
