hansaw11


A heavier and more powerful derivative of the KDW, the 1917 W.11 single-seat twin-float fighter biplane was powered by a 220hp Benz Bz IVa water-cooled engine and retained the "star" interplane bracing arrangement of its predecessor. Armament consisted of two synchronised LMG 08/15 machine guns, and two prototypes were completed during February-March 1917. No series production was undertaken.
