Brandenburg W
  Although actually a pre-war design of 1914, twenty-seven aeroplanes of this type were supplied to the German Navy for reconnaissance and general duties. The crude, dinghy-like appearance of the floats may be noted. Engine, 150 h.p. Benz Bz III. Span, 16.5 m. (54 ft. 1 1/3 in.). Length 9.4 m (30 ft. 10 1/8 in.). Area, 57.85 sq.m. (625 sq.ft.). Weights: Empty, 1,200 kg (2,640 lb.). Loaded, 1,830 kg. (4,026 lb.). Speed, 90 km.hr. (56.25 m.p.h )

Type W

  The Brandenburg W was a three-bay, two-seat floatplane with the pilot occupying the rear cockpit. The Type W, Heinkel's first seaplane design for Brandenburg, had been designed pre-war as a racing machine.(23) Previously the races had taken place on inland lakes. In 1912, an attempt had been made to have the race on the open sea; however, even the calm Baltic was too much for the aeroplane structures of the day, and, despite the wish of the Navy to hold the contest off the coast of the Baltic or the North Sea, the 1913 race was held on Lake Constance as the aeroplane manufacturers stated that they could not design types to meet the conditions to be expected on the high seas. In 1914 the race was going to again be attempted on the open sea as the Ostseeflug Warnemunde (Flight over the Baltic Sea at Warnemunde). Heinkel was sure he could develop a seaworthy floatplane using the Albatros B.II as the basis for the design. According to his autobiography Heinkel designed the machine in eight weeks. The Type W was at Warnemunde together with 26 other seaplanes for the competition as the Navy had promised a small contract for the successful seaplanes. AEG, Ago, Albatros, Aviatik, Brandenburg, Friedrichshafen, and Rumpler had entered aircraft in the competition. The commencement of the war meant the competition was abandoned. All 26 aeroplanes were impressed into German Navy service.
  Of conventional construction this three-bay biplane was marked by its crude floats. These were 4.850 m long and 0.900 m wide with a single step. The wings had dihedral and a slight sweep-back. The 150-hp Benz Bz.II(24) engine was exposed with Hazet
side radiators mounted under the forward cockpit. The rectangular fuselage tapered to a vertical knife edge. An Avro type comma shaped rudder and tail float completed the fuselage.
  After testing the prototype, the German Navy ordered a total of 23 machines as listed above. The type performed general duties and reconnaissance work.

(23) Although Heinkel's autobiography indicates it was a race, it appears that the contest was more towards a set of conditions for performance on the water and in the air.
(24) Gray &Thetford record the 150-hp Bz.III as the type's engine.

The Type W was a crude looking machine but reflected the state of the art at the time. The ungainly pontoons and two and a half bay bracing are noteworthy.
