France's "C2" two-seat fighter specification saw several entries, including the Breguet 17, a variant of the Breguet 14 with twin guns for the pilot and an additional downward-firing Lewis for the observer. While it possessed a powerful 420-450hp Renault engine, its flight characteristics must have been very much like the Breguet 14, and it was clearly outclassed by its C2 competitor the Hanriot H.D.3. Only ten were built and they were not available for service until 1919. Had the war continued, it is likely that some would have been built as escorts for flights of Breguet 14 bombers, but the plane would have mostly insurance against inadequate supply of the Hanriot.
