The British Aerospace BAe 125 is a twin-engined mid-size corporate jet, with newer variants now marketed as the Hawker 800. It was known as the Hawker Siddeley HS.125 until 1977. It is also used by the British Royal Air Force as a navigation trainer (as the Hawker Siddeley Dominie T1), and was used by the United States Air Force as a calibration aircraft (as the C-29).

Development
In 1961, de Havilland began working on a revolutionary small business jet known as DH.125 Jet Dragon. The first of two prototypes flew on 13 August 1962 powered by the Bristol Siddeley Viper turbojet
The aircraft went through many designation changes during its service life. Originally DH.125, it was renamed the HS.125 after de Havilland became a division of Hawker Siddeley in 1963. When Hawker Siddeley Aircraft merged with the British Aircraft Corporation to form British Aerospace in 1977, the name changed to BAe 125. Then, when British Aerospace sold its Business Jets Division to Raytheon in 1993, the jet acquired the name Raytheon Hawker. The fuselage, wings and tail-fin are to this day fully assembled and partially equipped (primary and secondary flight controls) in Airbus UK's Broughton plant, on the outskirts of Chester, sub-assemblies are produced in Airbus UK's Buckley (Bwcle in Welsh) site. All these assembled components are then shipped to Wichita, Kansas in the United States, to where final assembly was transferred in 1996.
Over 1,000 aircraft have been built.
