[edit] Development
Developed from a mix of the Maurice Farman designed Farman MF.11 and the Henry Farman designed Farman H.F.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.
[edit] 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.
