   Various two-seater seaplanes were designed and built in ones and twos by the Imperial Naval Yards (Kaiserlicht Werft) as follows: Danzig: Nos. 404-405, 467-470, 1105-1106 and 1650. Kiel: Nos. 463-466. Wilhelmshafen: Nos. 401-403, 461-462, 945 and 947.

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.

Kaiserliche Werften Type 945

  The only Kaiserliche Werften Type 945 was built at Kaiserliche Werft Wilhelmshaven. This was an armed, two-seat fighter powered by a 150 hp Benz Bz.III engine; other details have not survived. The aircraft was clearly inspired by the Brandenburg W12. The photograph proves it was completed but SVK records are missing for the period after June 1918 so the actual delivery date is unknown but after June 1918. By this time the fast Brandenburg monoplane W29 and W33 were in combat, so the biplane Type 945, which was undoubtedly slower, had no prospects of quantity production.
