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 462
  
  The Kaiserliche Werften Type 462 was built at Kaiserliche Werft Wilhelmshaven (two aircraft, Marine numbers 461 & 462) and KW Kiel (four aircraft, Marine numbers 463-466). These were unarmed, two-seat trainers powered by 150 hp Benz Bz.III engines. They were conventional, two-bay biplanes with the wire-braced, fabric-covered wood structures typical for the time but cleanly designed. The photos show that the interplane bracing of #461 differed notably from that used on #462 and #463.

Kaiserliche Werften Type 462 Specifications
Engine: 150 hp Benz Bz.III
Wing: Span 14.9 m
Wing Area 52 m2
General: Length 9.5 m
Height 3.9 m
Empty Weight 1,016 kg
Loaded Weight 1,585 kg
Maximum Speed: 143 km/h
Climb to 1,000 m: 10.7 min.


Kaiserliche Werften Type 467

  The Kaiserliche Werften Type 467 was built at Kaiserliche Werft Danzig (four aircraft, Marine numbers 467-470). These were unarmed, two-seat trainers powered by 150 hp Benz Bz.III engines. They were conventional, two-bay biplanes with the wire-braced, fabric-covered wood structures typical for the time. These Danzig-built floatplanes were supplied to the nearby naval base at Putzig.

Kaiserliche Werft Wilhelmshaven

Aircraft Development:

<...>
  The KW Wilhelmshaven Marine Numbers 461 and 462 (Type 461, also known as W 10) were of the unarmed, two-seat floatplane (B-type) genus according to the Kaiserliche Marine’s aircraft group classification.

Kaiserliche Werft Kiel

Foundation:

  When the Kaiser Wilhelm Canal was finally completed in 1895, the Kaiserliche Werft Kiel moved to Kiel-Gaarden-Ost in 1899. Between 1899 and 1904, the area of the shipyard expanded to such an extent that the Germania shipyard in the south had to cede part of its site to the Kaiserliche Werft. The operation also continued to grow to the north, and in 1904 the last remnants of the old fishing village of Ellerbek disappeared with the expansion of the shipyard. To connect the two parts of the shipyard, the suspension ferry was completed in 1910 and soon became a landmark in Kiel.


Aircraft Development:

  Kaiserliche Werft Kiel received an order for four seaplanes in October 1915. The first aircraft of this batch (# 463) was delivered to the seaplane testing unit (SVK - Seeflugzeug-Versuchskommando) at Warnemunde near Rostock the following summer. It remained there under test for well over one year and was not finally accepted for service until summer 1918. This lengthy delay was possibly due to the aircraft being used as a trainer at Warnemunde itself.
  Marine number 463 was a conventional, two-bay biplane with unstaggered wings of equal span and two open cockpits for the pilot and instructor. The undercarriage consisted of twin pontoons. The large, square rudder was hinged to the rear end of the fuselage and extended below the ventral line of the fuselage.
