The AEG C.III was a prototype reconnaissance biplane designed as a two-seater by the German manufacturer Allgemeine Elektricitäts-Gesellschaft (AEG) during World War I for use by the Imperial German Army's air arm, the Luftstreitkräfte. It evolved from the earlier C.II model but featured a redesigned fuselage that completely bridged the gap between the upper and lower wings. To optimize the observer's field of fire, the upper wing was mounted directly atop the fuselage, positioning the observer in the front cockpit with enhanced visibility. Although one or two prototypes were commissioned in late 1915, the C.III did not proceed to operational deployment.

Development

The design incorporated a distinctive fuselage configuration inspired by the Roland C.II, where the body filled the space between the two-bay wings, eliminating the typical gap found in biplanes. The upper wing was affixed to the fuselage's upper longerons while the lower wing connected to the lower longerons. This arrangement aimed to reduce aerodynamic drag by removing cabane struts that usually supported the upper wing attachment. Positioned ahead of the pilot and above the upper wing, the observer enjoyed an unobstructed field of view for operating his flexible-mounted 7.92 mm (.312 in) machine gun. However, since no interruptor gear was installed, firing through the propeller arc was not possible. Power was provided by the same water-cooled 150-horsepower (110 kW) Benz Bz.III straight-six engine used in the C.II.

The initial prototype conducted its maiden flight in December 1915, but subsequent testing revealed that the reduced gap between wings caused aerodynamic interference, which negatively impacted performance and handling characteristics. Due to these limitations, further refinement of the model was discontinued.
