W.Green, G.Swanborough The Complete Book of Fighters
BRANDENBURG KF Germany
The first fighter to be designed by Ernst Heinkel as chief designer for the Hansa- und Brandenburgische Flugzeug-Werke, the KF two-seater appeared early in 1916, and was a two-bay, twin-boom biplane powered by a 150 hp Benz Bz III six-cylinder water-cooled engine installed as a pusher and driving a two-bladed propeller between the tailbooms. The KF was of wooden construction with plywood-covered fuselage nacelle and tailbooms, and armament was intended to consist of a single 7,92-mm Parabellum machine gun on a flexible mounting in the forward cockpit. Work on the KF was discontinued as it offered no advance in performance over the similarly-configured Ago C I which served in the reconnaissance role.
