The AEG C.III was a two-seat biplane reconnaissance aircraft, a single prototype of which was built during World War I. The aircraft featured an unusual fuselage design that completely filled the gap between the upper and lower sets of wings, to provide the pilot with improved vision, and to allow the observer a wider field of fire for his 7.92 mm (.312 in) machine gun. The pilot sat to the rear of the observer, who was stationed over the upper wing. This design was not as successful as had been hoped, and the C.III was never entered into service. Despite being heavier than the C.II, its maximum speed increased to 158 km/h (98 mph).
