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 crew nacelle. An open tail boom truss 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. The Portuguese Forces in Mozambique included a small squadron of F.40, which participated in the East African Campaign.
Italian aircraft maker Savoia-Marchetti built F.40s for use by the police force until 1922.
