Farman F.40


The Farman F.40 was a French pusher biplane reconnaissance aircraft. The aircraft was also used as light bomber aircraft in the early part of World War I and later it was used as a trainer.

Development

Developed from a mix of the Maurice Farman-designed MF.11 and the Henry Farman-designed HF.22, the F.40 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 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.
A number of 120 Farman F.40s were purchased by Romania. These included the Type 42 and Type 60 variants of which 57 equipped with De Dion engines, 46 with Renault engines, and 17 with Renault engines. The Farmans were assigned to squadrons of Grupul 1, Grupul 2 and Grupul 3 and were used until 1920. A Farman F.40 was also used to deliver some important documents for the Union with Transylvania to the Romanian National Council in 1918.
Italian aircraft maker Savoia-Marchetti built F.40s for use by the police force until 1922.
