J.Herris Friedrichshafen Aircraft of WWI (A Centennial Perspective on Great War Airplanes 21)

Friedrichshafen FF19

   Although a later design, the FF19 actually flew in April 1914 before the FF17. It featured a three-bay biplane wing cellule that was simpler than the FF17, perhaps one reason it was flown earlier. A tractor floatplane powered by a 100 hp Mercedes D.I, it was the first Friedrichshafen pre-war design to go into limited production, a total of 16 being built.
   The first FF19 order for five aircraft, Marine Numbers 25-29, was built in the period 17 May to 18 June 1914 in Kiel. The second order was for 10 aircraft, Marine Numbers 76-85, immediately after the outbreak of war. The FF19s, together with 3 Agos ordered at the same time, were then the only naval maritime aircraft capable of fulfilling a combat role. The 16th airframe was used for static load testing.
   The FF19 was historically significant as the first German aircraft from which successful wireless tests were carried out.

11. The F.F. (Flugzeugbau Friedrichshafen) Seaplane
is a biplane of the tractor type, having a rectangular section body, and main planes which are straight as seen in plan but which are set at a dihedral angle. The engine - a 135 h.p. N.A.G. - is mounted in the nose of the body, and long exhaust pipes carry the exhaust gases down below the lower plane. Immediately behind the engine is the passenger's seat, whilst further back, to the rear of the trailing edge of the planes, is situated the pilot's seat. The two main floats are of the single stepped type, and are spaced comparatively wide apart in order to increase the lateral stability of the machine on the water. In previous models a single central float was fitted. A small float fitted under the rear part of the body takes the weight of the tail planes when the machine is at rest.

The FF19 was the first Friedrichshafen design to be produced in quantity. A total of 16 airframes were built; 15 were delivered to the Navy and one airframe was used for structural testing.

Friedrichshafen FF19 Marine Number 25 at Borkum wearing late-style insignia. Research by Frits Gerdessen reveals that, on 14 August 1914, Friedrichshafen FF19 seaplane #28 beached at Schiermonnikoog. The plane was later acquired for the Netherlands Navy and the crew, Oberleutnant zur See Hubert Waldemar Klein and Fahnrich zur See Carl Georg Philipp, was interned at Bergen. This was the first of many naval aircraft interned by the Netherlands during the war.

Friedrichshafen FF19 seaplanes 25 and 26 enjoying unusually calm sea conditions in the Heligoland Bight. They were part of a five-aircraft order placed in February 1914, harbingers of the three-bay Friedrichshafen seaplane layout that became the FF33 when powered by the 150hp Benz and the FF49 when the 200hp Benz was used. This basic design, developed over the following two years, had not been improved upon for general workaday duties by the time of the Armistice, and the later models were the most widely used reconnaissance seaplanes in service.

Mobilization seaplanes on the ramp at Kiel-Holtenau in August 1914. Aircraft identified in this early wartime photograph include: Rumpler 4B11 (150hp Benz) from Warnemunde, Sopwith Bat-Boat 44 (which was never used operationally but merely for short local flights), Friedrichshafen FF19 23 and Albatros B I on floats, which was another machine taken over on the outbreak of war at Warnemunde. All aircraft are carrying red streamers from the bottom wings near the tips for identification purposes and are marked with the Iron Cross type of national insignia.
