The DFW C.IV, C.V, and C.VI were a family of German reconnaissance aircraft first used in 1916 in World War I. They were conventionally configured biplanes with unequal-span unstaggered wings and seating for the pilot and observer in tandem, open cockpits. Like the C.II before them, these aircraft seated the gunner to the rear and armed him with a machine gun on a ring mount. Compared to preceding B- and C-class designs by DFW, however, the aerodynamics of the fuselage were more refined, and when coupled with more powerful engines than these aircraft resulted in a machine with excellent performance.

Design and development
The C.IV had a single-bay wing cellule and was powered by a 112 kW (150 hp) Benz Bz.III. It was soon replaced in production by the definitive C.V with a two-bay wing cellule and either a 112 kW (150 hp) Conrad C.III or 149 kW (200 hp) Benz Bz.IV. Predictably, the latter, more powerful engine gave significantly better performance.
The C.V's main designer was Heinrich Oelerich, and it was produced in larger numbers than any other German aircraft during World War I. About 2000 were manufactured in DFW and about 1250 licence maufactured by the Aviatik (DFW C.V (Av), designated also as Aviatik C.VI), Halberstadt, LVG, and Schütte-Lanz.
A further and final development was C.VI, a sturdier aircraft powered by a 164 kW (220 hp) Benz Bz.IVa.
Operational history
It was used as a multirole combat aircraft, for reconnaissance, observation, bombing by Germany and Austro-Hungary during World War I. They were also used by the Ottoman Empire in Palestine. In the hands of a skilled pilot it could outmaneuver most allied fighters of the period. It remained in service until early 1918 though 600 were still in use by the Armistice of 11 November 1918. Most were thereafter scrapped according to Versailles Treaty in 1919.
Poland seized 11 aircraft in 1919 and manufactured further 13 in 1920 from seized parts. Several other D.Vs were bought in 1920. They were used by the Polish Air Force in Polish-Soviet war.
Two were used post-war in Finland, four in the Netherlands, two in Switzerland and a number in Estonia. Eight aircraft were converted to civilian ones and used by Deutsche Luft Rederei. A number of copies were built by the Bulgarian state aircraft workshops after the war as the Uzunov-1
Only one fuselage of DFW C.V(Av) survived in the Polish Aviation Museum in Kraków.
Operators
- Finnish Air Force operated two DFW C.V. aircraft during 1918-1921.
- Polish Air Force operated up to 34 aircraft.
Description
It was a biplane of mixed, mostly wooden construction. A fuselage of a wooden frame, covered with plywood. Two-spar rectangular wooden wings, canvas covered. Upper wing of slighlty greater span, with extended ends with ailerons. Tail of metal frame, covered with canvas. Straight engine in a fuselage nose, with a chimney-like exhaust pipe (LVG-produced planes had horizontal exhaust pipe). Engine was initially covered with an aerodynamic cover, but it was often abandoned. Two-blade wooden propeller, 2.8 m diameter. Water radiators on both fuselage sides, later water radiator before upper wing. Fixed conventional landing gear, with a straight common axle and a rear skid.
