From the Manufacturer

The Hawker 400 is a small twin-engine corporate aircraft which was designed by Raytheon's Beech Aircraft Company subsidiary (now a part of Hawker Beechcraft). The aircraft was originally designed as the Mitsubishi MU-300 Diamond. Beechcraft bought the production rights and began manufacturing it as their own model. The Hawker 400 was initially redesignated as the Beechjet 400 and was certified by the FAA in May 1985. Beechcraft further developed their own improvements to the Beechjet 400 model leading to the 400A in 1990. In 1993, Beechcraft purchased Hawker business jet products from British Aerospace. The Hawker 400XP is the latest model, incorporating further aerodynamic, mechanical and interior improvements gleaned from the Hawker 800XP. Hawker 400XP general characteristics include 2 pilot seats for crews, capacity of 7 passengers and a maximum speed of 518 mph. The Hawker 400XP is a unique aircraft offering value, flexibility and low operating costs combined with the ruggedness, spaciousness and technological sophistication of a much larger jet. The Hawker 400XP is powered by Pratt and Whitney Canada engines. The aircraft is the fastest light-jet market. Its innovative design includes a well-equipped galley, four-space center-club seating and has the largest cabin of any comparable aircraft.
