The Albatros C.III was a German two-seat general-purpose biplane of World War I, built by Albatros Flugzeugwerke.
The C.III was a refined version of the successful Albatros C.I and was eventually produced in greater numbers than any other C-type Albatros.
Like the Albatros C.I, the C.III was a popular aircraft with rugged construction and viceless handling.
The most prominent difference between the two was the revised vertical stabilizer.
The C.III had a lower, rounded tail compared to the large, triangular tail of the C.I, which, combined with smaller weight, gave the C.III greater agility.
The power plant was either a 110 kW (150 hp) Benz Bz. III or a 120 kW (160 hp) Mercedes D.III inline engine and, like numerous other two-seaters used during the war, the cylinder head and exhaust manifold protruded above the front fuselage, limiting the pilot’s forward visibility.
The observer, who occupied the rear cockpit, was armed with a single 7.92 mm (0.312 in) Parabellum MG14 machine gun.
C.III aircraft were typically fitted with a gun synchronizer and a single forward-firing 7.92 mm (0.312 in) LMG 08/15 machine gun.
The C.III could also carry a bomb load of up to 90 kg (200 lb) in four vertical tubes in the fuselage or external racks.
Between 1926 and 1927, two Mercedes D.III engined copies were built from saved parts and components of the destroyed aircraft by Bulgarian state aircraft workshops DAR as the DAR 2 for use as trainers.
According to D. Nedialkov, twelve DAR-2 were built (at least nine are confirmed by a photograph).
