Friedrichshafen FF 29
Built in small quantity from November 1914, the FF 29 and FF 29a (powered with 120 h.p. Mercedes D II engine) were used for coastal patrol and sometimes carried a small bomb load. No other armament was carried. The FF 29a had modified tail surfaces and floats.

SOME FRIEDRICHSHAFEN "MILESTONES"

   PROBABLY no other German aircraft firm can show such a series of seaplanes as that produced by the Friedrichshafen Aircraft Works (Flugzeugbau Friedrichshafen) during the War, and for this reason a brief reference to the various types, illustrated by photographs, may not be without interest to readers of FLIGHT. The illustrations have been published in Flugsport, and the following is a translation of the descriptive matter accompanying the photographs :-
   "The Friedrichshafen Aircraft Works is the oldest German firm which has devoted its energies almost exclusively to the production of seaplanes. The firm was founded in 1912 and has produced a great number of seaplane types, under the efficient leadership of its founder and managing director, Dipl. Ing. Theodor Kober, who has been ably supported by his associates, in close co-operation with the Naval authorities and with various scientific institutions. The main sphere of activity of the firm was the construction, testing, and quantity production of seaworthy single-engined seaplanes of the types used by the German Navy for reconnaissance flights over the North Sea and the Baltic. That the firm was successful in this is proved by the fact that they have been able to supply practically all the requirements of the German Navy, and that a number of other firms have built their machines under licence. Among these may be mentioned the Luftfahrzeug Gesellschaft, the Sablatnig Aircraft Works, the Gothaer Waggonfabrik and the Warnemunde Aircraft Works. As the seaworthiness of a machine depends not only on the right shape of float, but also upon the strength of the floats and undercarriage, on the correct amount of buoyancy and on controllability when alighting, it will be seen what an abundance of experience has to be collected in order to fulfil the specifications for a seaworthy seaplane. A large proportion of the experiments was formed by tests on floats, of which over 100 types were produced. The F.F. machines, which have been well proved during the War, are all of the twin-float type, although before the War single-float machines and flying boats were also tried.
   "One object of the experiments was, among other things, to determine the number and placing of steps which best suited the different types of machines for starting and landing, and what float shape gave the best results for taxying. At the same time the floats should combine small air resistance and great rigidity with small weight, while the most suitable, strongest, and lightest construction of float details also required much work and very many experiments. The following are the most important types of seaplanes produced by the Friedrichshafen Aircraft Works :-

"The F.F. 29
   is a bomber with a 120 h.p. Mercedes engine (Fig. 1). The main floats are comparatively short, and a tail float is therefore fitted under the stern of the fuselage. The radiator is placed above the engine, and the exhaust pipes are passed under the lower plane. The pilot occupies the rear seat, while the observer sits in front, where are also the bomb releases. The petrol gravity tank is hung on the cabane struts.

Friedrichshafen FF29 Marine Number 211 was an FF29 powered by a 120 hp Mercedes D.II.
This type, equipped with a 120 hp Mercedes D.II engine, was an enlarged version of the FF.19. Series 1 comprised 20 aircraft, series 27 (with Argus engine), series 3-5 a total of 17 aircraft. The FF29 was replaced by the FF35 from March 1915.

Friedrichshafen developed a superb series of seaplanes during the war. The FF29, as here, was produced from late 1914 for coastal patrol duties.

Marine Number 419 was a Friedrichshafen FF33A, while Marine Number 294 was an FF29. The early FF33 and FF33A were virtually FF29 aircraft; later FF33 variants used more powerful engines, mostly the 150 hp Benz Bz.III.

When HMS Maori, engaged in sketching salient features on the Belgian coast, hit a mine off Blankenberghe and sunk on 7 May 1915, her yard-arm and this flag remained above the water. Despite rough seas, Oberleutnant zur See Drekmann (right) landed his Friedrichshafen FF29 209. Then, with his observer, Fahnrich zur See von Bliicher, hanging on to the starboard front interplane strut with an open clasp knife held in his teeth, pirate fashion, Drekmann managed after several attempts to position von Blucher so that he could cut the flag free. A hazardous take-off followed and the plucky fliers brought their booty back to Zeebrugge. (British destroyers at sea flew either the Red Ensign or the Union Flag from their yard-arms for recognition purposes, but the Germans did not know this and were puzzled as to why a Royal Navy vessel should be flying the 'Red Duster'!)

Built in early 1914, the Oertz F.B.3 was purchased by the Navy and assigned Marine Number 46. Here it is shown at Zeebrugge in early 1915, after national markings and Marine Number have been applied between Friedrichshafen FF29 floatplanes #208 and #204. Marine Number 407 in the background is another Friedrichshafen FF29.

Following the occupation of the Belgian coast, a seaplane base was established at Zeebrugge in December 1914. Aircraft were kept in the railway station hall at the end of the Mole, fully assembled on specially constructed flat railway cars which carried tools, fabric, dope, etc for minor repairs, as well as supplies of water, fuel and oil. Locomotives were kept with steam up and were always available to pull the trains out on to the Mole and up to the cranes used to lift and lower the seaplanes to the water. In this early 1915 scene no national insignia are displayed on the upper wing surfaces of these Friedrichshafen FF29 seaplanes or the Oertz flying-boat numbered 46, but wing undersurfaces were marked spanwise with the straight-sided cross, as seen on the Oertz's rudder.

LAUNCHING A GERMAN SEAPLANE. - Before the war a good many attempts were made by German constructors at producing a combined wheel and float undercarriage so as to enable machines to start from or alight on either land or sea. In the above photograph, however, the wheels and tackle on top of the floats appear to be detachable to be used probably for running the machine short distances over land, and left behind when she takes the water. The floats, it will be observed, are of the two-stepped type, the first two sections being flat-bottomed, while the portion behind tbe rear step has a Vee bottom. The flags on the lower wing tips are in all probability fitted to a cable, and movable for signalling purposes.

Early on 6 January 1915 an FF29a was lashed to the deck of the U-Boat U-12 as an experiment to see if the submarine could take the aircraft out into the North Sea where it could perform reconnaissance duties for the submarine. The machine had to be lashed with the wings parallel to the submarine's length. Despite a fairly heavy sea the FF29a was launched successfully about 30 miles out from Zeebrugge. Unfortunately, the conditions deteriorated such that the pilot of the seaplane did not try to make the rendezvous with the submarine but flew back to base. While the idea had worked it was apparent that much more work would be required to develop a true integration of the submarine and an aircraft. This photo may have been related to that experiment.
