British Aerospace 125 series / Hawker/Raytheon 700/800/800XP/850/900

The British Aerospace 125 series is a twin-engine business jet that originated with the de Havilland DH.125 in the early 1960s. It passed through several corporate identities — Hawker Siddeley, British Aerospace, Raytheon, and Hawker Beechcraft — evolving through numerous variants while retaining a recognizable fuselage lineage. The ICAO designator H25B broadly covers the Hawker 700 through 900 family used in commercial and business aviation contexts. The series is best known for its robustness, all-weather capability, and transatlantic range in later variants. The Hawker 800 and 800XP became the most commercially successful members of the family, widely adopted by charter operators, fractional ownership programs, and corporate flight departments worldwide. The Hawker 900XP introduced winglets and updated Honeywell TFE731-50R engines, improving fuel efficiency and range. Production effectively wound down after Hawker Beechcraft filed for bankruptcy in 2012, ending new deliveries of the 900XP. The type remains widely in service globally, valued for its proven reliability and mature support infrastructure. The 850XP variant added winglets to the 800XP airframe as an interim step before the 900XP.
