Breguet 17

  In November 1916 the STAe formulated a requirement for a two-seat lighter designated the Type C. Breguet submitted a variant of the type AV prototype intended to meet this specification. This two-seater was eventually developed into the Breguet 17. A fighter version of the Breguet 14 bomber would have ensured that the Breguet 14 bomber formations contained escort planes of comparable performance.
  In early 1918 Breguet started design work on the new escort fighter. Initial attempts included a Breguet 14 with a 370-hp Lorraine-Dietrich engine. Other designs were greater departures from the classic Breguet 14 layout, including an aircraft with a 400-hp Renault 12J engine and one armed with a cannon in a turret.
  The new fighter, designated Breguet 17 C2 (two-seat fighter) appeared in the summer of 1918. Given serial 022, it was powered by a 400-hp Renault 12R. Externally, it was almost identical to the standard Breguet 14 A2. Major changes included a horizontal exhaust stack mounted to starboard in order to improve the pilot's vision, a smaller wing span and area, altered bracing wires, a new fin and rudder, and greatly increased armament. The latter consisted of two fixed 0.303 Vickers machine guns for the pilot and twin Lewis guns on a swivel mount for the observer. In addition, there was a third Lewis gun mounted in the belly of the aircraft that also was used by the observer.
  The prototype flew in mid-1918, but its performance seems to have been considered inadequate. Modifications were introduced, including a more powerful 450-hp Renault 12R1 engine and redesigned wings with a deeper under-camber. Although still not of completely satisfactory performance, the Breguet 17 C2 entered series production. A night fighter variant was designated the Breguet 17 Cn 2.
  Apparently only about ten of the aircraft were ever built, as the contemporary Hanriot HD.3 was believed to be a superior fighter. The few Breguet 17s built were not available for service until 1919. The aircraft produced in series had horn-balanced ailerons of reduced chord and an enlarged, horn-balanced rudder. As there were not enough aircraft to form a single escadrille, the Breguet 17s were sent to individual escadrilles for record-breaking and long-distance flights. Notable flights include a high-altitude record achieved on 12 February 1923 when Lt. Benoit flew a Breguet 17 to 5,516 m with a 500-kg load, a flight from Paris to Stockholm in 8 hours 15 minutes, and a series of long distance flights in 1923.
