Farman F.40

The Farman F.40 was a French pusher biplane reconnaissance aircraft.

Development
Developed from a mix of the Maurice Farman designed MF.11 and the Henry Farman designed HF.22, the F.40 (popularly dubbed the Horace Farman) had an overall smoother outline and smoother crew nacelle. A pair of upper tail booms supported a horizontal tailplane and a curved fin. The aircraft went into production in 1915.

Operational history
Forty French Air Force escadrilles (squadrons) were equipped with F.40s. They operated for just over a year, but were replaced in early 1917.

The F.40 was also operated by the No. 5 Wing of the Royal Naval Air Service, Belgian forces in France, and also by the Russians

Italian aircraft maker Savoia-Marchetti built F.40s for use by the police force until 1922.
