The Hawker 800 is a series of mid-size corporate aircraft developed from the British Aerospace BAe 25 by Hawker Beechcraft. It has a number of modifications and changes over the 700, the most noticeable being the redesigned cockpit windscreen. Accompanying this are a modified rear fuselage fairing, as well as a glass cockpit. The 125-800 series proved to be successful on the market. It took nineteen years until the 500th BAe 125 airframe was sold, while in a little over five years British Aerospace were registering the 200th sale of the 800 series. The Hawker 900XP is a direct development of the Hawker 850XP and was introduced to the market in 2007.

The Hawker 900XP improves on some of the best traits of the Model 850XP, including fuel efficiency, aerodynamics, and performance capabilities. Updated winglets improve hot-and-high performance, range, and takeoff distance. Powered by two Honeywell TFE731-50R engines with 4,660 pounds of thrust, this aircraft has a full range of 2,733 nm with full fuel under NBAA IFR.

One of the most noticeable similarities between the Hawker 900XP and the 800XP is the Collins Pro Line 21 avionics suite. including terrain awareness warning systems, weather, reduced vertical separation minimum, and enhanced ground proximity warning systems. The interior features LCD lighting, touch-screen seat controls, plenty of in-cabin storage, and stand-up headroom.

Production of the Hawker 900XP ended in 2012, with a total of 183 aircraft being delivered. 13.1% of the fleet is currently for sale on the market, where they usually spend an average of 183 days. North America holds the largest percentage of Model 900XP aircraft with 63%, and Asia follows with 16%. An additional 11% is operated in Europe.
