K.W. (Wilhelmshafen) No.945

   The Naval Shipyard at Wilhelmshafen built a small number of prototype seaplanes, none of which were produced in quantity. One prototype built there was the K.W. No.945, a two-seat naval fighter clearly inspired by the Brandenburg W12. It was powered by a 150 hp Benz Bz.III engine, a powerplant used by many Brandenburg W12s. Other than its engine, few details survive.
