The AEG C.I was a two-seat biplane reconnaissance aircraft produced in small numbers from March 1915 by the German company Allgemeine Elektrizitäts-Gesellschaft (AEG).
It was essentially an AEG B.II armed with a single 7.92 mm (.312 in) Parabellum or Bergmann (rarely) machine gun mounted at the rear of the cockpit for the observer and a more powerful engine.
The Benz engine increased maximum speed to a more respectable 130 km/h (81 mph).
By October 1915, it had begun to be replaced by the AEG C.II.
The AEG C.II was a German two-seat biplane reconnaissance aircraft produced in small numbers from October 1915.
It was a slightly smaller version of the C.I with better performance, redesigned cockpit for both pilot and observer/bombardier, new rear mounting for a 7.92 mm (.312 in) Parabellum MG14 machine gun, and the ability to carry four 10 kg (22 lb) bombs for light attack duties.
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).
