Farman three-engine flying-boat

The Farman three-engine flying-boat, also called the High Seas Flying Boat, was an otherwise unnamed and undesignated flying boat built by Farman for the Aéronavale, the French Navy air service, of which two examples were operated for a short time. It was of conventional flying-boat layout, influenced by the designer Maurice Blanchard's time with Georges Lévy, an unequal-span unstaggered two-bay biplane with two pilots side by side in an open cockpit and two gunners, one at the bow and one amidships. Three piston engines of 250 kilowatts each sat in the interplane gap, the centre one above the hull driving a pusher propeller. It answered the French service requirement of 1 January 1918 for a long-range maritime patrol flying boat, first flew in 1921 and formed the short-lived escadrille H401 in 1922 and 1923.
