The Hawker 800 is a mid-size corporate aircraft developed from the British Aerospace BAe 25 by Hawker Beechcraft. The Hawker 800A is the first of the series 800 and had its first flight on May 26, 1983. The 125-800 series would become a sales success. 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 800B in the most basic translation was a European edition aircraft.
The Series 800 includes increased wingspan, streamlined nose, tail-fin extension, increased fuel capacity, an EFIS cockpit, and upgraded engines. The Hawker 800B has a number of modifications and changes over the Model 700, the most noticeable being the redesigned cockpit windscreen. Accompanying this are a modified rear fuselage fairing, as well as a glass cockpit and upgraded Honeywell TFE731-5R engines with 4,600 pounds of thrust. British Aerospace also improved the wing by incorporating new outer wing sections. This helped to reduce drag and improve aerodynamic efficiency.
Primary operators of the Hawker 800B include Japan Air Self-Defense Force, Brazilian Air Force, and Royal Saudi Air Force.
