One of the initial two C.VII prototypes equipped with a straight upper wing

The AEG C.VII was a two-seat biplane reconnaissance aircraft prototype constructed by Allgemeine Elektricitäts-Gesellschaft (AEG) amid the First World War for use by the Imperial German Army's (Deutsches Heer) air service, the Luftstreitkräfte. Derived from the earlier AEG C.IV, this model did not proceed to mass production. During testing, the aircraft was evaluated with two wing configurations: one featuring straight wings and another with a swept upper wing.

Development

The design of the C.VII responded to the specifications issued by the Inspectorate of Flying Troops (Inspektion der Fliegertruppen or Idflieg), which sought a smaller two-seat aircraft compared to existing C-type models. These planes were intended for deployment within protection flights (Schutzstaffeln) tasked with escorting reconnaissance units. In October 1916, three prototypes were commissioned, with the first completed by December of that year. The C.VII was approximately 20 percent smaller than its predecessor, the C.IV, and incorporated single-bay wings. Both aircraft utilized the same 160-horsepower (120 kW) water-cooled Mercedes D.III straight-six engine and were armed with one fixed forward-firing machine gun plus a flexible-mounted gun operated by an observer. Compared to the C.IV, the C.VII achieved an increase in speed of about 20 kilometers per hour (12 mph) and demonstrated improved climb performance. The initial two prototypes featured upper wings with straight leading edges; however, the third prototype adopted a swept upper wing design aimed at enhancing the observer’s field of fire.

Flight evaluations took place in early 1917. According to an Idflieg report dated 30 April, the aircraft’s performance was deemed adequate but fell short of expectations. It was considered suitable primarily for operations on the less demanding Eastern Front, yet it was regarded as inferior compared to competing designs submitted by Hannoversche Waggonfabrik and Halberstädter Flugzeugwerke.
