The unarmed Lohner B.VII and its armed derivative the C.I were military reconnaissance aircraft produced in Austria-Hungary during World War I.

The B.VII appeared in August 1915 and finally provided a machine suitable for service use.

Many B.VIIs in operational service were equipped with machine guns on flexible mounts for the observer,[2] and this led to the armed C.I version being produced at both the Lohner and Ufag factories.

Aside from its factory-installed armament, the C.I also sported a streamlined cowling around the engine, whereas the B-types had their cylinders exposed to the airstream.

Notable missions carried out by these aircraft included the raid on the Porta Volta power station in Milan on 14 February 1916 (a 378 km/276 mi round trip for 12 B.VIIs)[3] and Julius Arigi sinking an Italian steamer at Valona in a B.VII in 1916.
