The Fairey Ferret was a 1930s British general purpose biplane designed and built by the Fairey Aviation Company.[1] It performed well in trials but it was not ordered into production.[1]


The Ferret was designed to meet a Fleet Air Arm requirement defined by specification 37/22[2] for a reconnaissance aircraft; it was the company's first all-metal design.[1] With a lack of interest from the FAA the company proposed the design to meet a Royal Air Force requirement for a general-purpose biplane.[1]

The company built three prototypes, two were three-seaters (to meet the naval requirement) and the third was a two-seater.[1] The two-seater Ferret III was also fitted with a new Fairey-designed high-speed gun mounting in the rear cockpit.[1] The first prototype first flew in June 1925 powered by a 400 hp (298 kW) Armstrong Siddeley Jaguar IV radial engine.[1] The other two aircraft had a 9 inch extension to the wing span and were both fitted with a 425 hp (317 kW) Bristol Jupiter radial engine.[1]

The aircraft performed well during trials at RAF Martlesham Heath but was not ordered into production.[1]
