The Hawker 800XPR started life in 2010 as an upgrade for the Hawker 800XP series. The 800XPR upgrade program features an engine upgrade to Honeywell TFE 731-50R power plants, each offering 4,669 pounds of thrust. The new engines have a 6,000 time between overhauls (TBO) compared to the original engines' 4,200 hour time between overhauls (TBO). The upgrade also added company-designed winglets. Both upgrades offer substantial performance improvements over the stock 800XP and an optional avionics upgrade is also available for the XPR.
The Hawker 800 is a variant of the world's longest running corporate jet production program.
The HS 125-700 and Hawker 800 are direct developments of the DH-125 (later the HS- 125), which first flew in August 1962. This aircraft was developed into a number of variants through to the HS-125-600, all of which are powered by the Rolls-Royce Viper turbojet and are described separately under Hawker Siddeley.
The introduction of the HS-125-700 in 1976 brought with it significant performance and fuel economy benefits with the Honeywell TFE-731 turbofans. The 125-700 first flew on June 19, 1976, and the model remained in production until it was replaced by the 125-800 in 1984.
The 125-800 first flew on May 26, 1983, and introduced a number of improvements. Aerodynamic changes included a re-profiled nose and windscreen, extended fin leading edge and greater span wing, which decreased drag and increased lift and fuel capacity. Range was further boosted by a larger ventral fuel tank. More powerful TFE-731s improved field performance and a redesigned interior made more efficient use of the space available. The 800 was also the first corporate jet to feature an electronic flight instrument system (EFIS) cockpit and is now available with the Collins Pro Line 21 avionics suite. The 800A was specifically aimed at the U.S. market, the 800B for non-U.S. markets.
The 125-800 became the Hawker 800 in mid-1993 when Raytheon purchased BAE's Corporate Jets division. Production was transferred to Wichita, KS, and the first U.S.-built 800 flew on November 5, 1996. The last UK-built 800 flew on April 29, 1997.
