OEFFAG TYPE CF (50.14) Austria-Hungary
Late in 1917, the Oesterreichische Flugzeugfabrik (Oeffag) of Wiener Neustadt initiated the design of its first and, in the event, only single-seat fighter, the Type CF. An equi-span triplane of wooden construction with I-type interplane struts, the Type CF was powered by a 225 hp Austro-Daimler six-cylinder water-cooled engine, intended armament comprising two synchronised 8-mm Schwarzlose machine guns. Flight testing began in May 1918, but the triplane was already outmoded by contemporary biplane development, the Type CF being viewed by the K.u.K.Luftfahrttruppen as retrogressive. Nevertheless, the prototype appeared in the Fighter Evaluation held at Aspern in July 1918. In the meantime, the two-piece upper wing had given place to a one-piece wing with ailerons of increased area, a 200 hp Austro-Daimler engine having supplanted the more powerful unit. Too heavy and unwieldy, the Type CF aroused no enthusiasm, having neither performance nor manoeuvrability to commend it, and further development was abandoned.
