The AEG C.I was a two-seat biplane reconnaissance aircraft produced in small numbers from March 1915. It was essentially an 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. A more powerful 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.
