The Fairey Aviation Company Limited was a British aircraft manufacturer of the first half of the 20th century based in Hayes in Middlesex and Heaton Chapel and RAF Ringway in Lancashire. Notable for the design of a number of important military aircraft, including the Fairey III family, the Swordfish, Firefly, and Gannet, it had a strong presence in the supply of naval aircraft, and also built bombers for the RAF. After World War II the company diversified into mechanical engineering and boat-building. The aircraft manufacturing arm was taken over by Westland Aircraft in 1960. Following a series of mergers and takeovers, the principal successor businesses to the company now trade as FBM Babcock Marine Ltd., Spectris plc, and WFEL (formerly Williams Fairey Engineering Limited), the latter manufacturing portable bridges.
