The Hawker 400 is a small twin-engine corporate aircraft, designed by Raytheon’s Beech Aircraft Company subsidiary, now part of Hawker Beechcraft.
It is a small, low-winged, twin-turbofan aircraft of all metal construction, flown by a crew of two pilots and accommodating up to eight passengers (depending on seating configuration) in a pressurized cabin. Its wings use a computer designed, supercritical airfoil in order to minimize drag. Its two Pratt & Whitney Canada JT15D turbofans are mounted on the rear fuselage.
Raytheon/Beechcraft steadily developed improvements to the model, leading to the 400A in 1990. Improvements in the 400A include longer range, higher take-off weights and improved luxury appointments.
In 1993 Raytheon purchased the Hawker business jet product line from British Aerospace. The Beechjet 400 was eventually renamed the Hawker 400 to map it into the Hawker product line. The Hawker 400XP incorporates further aerodynamic, mechanical and interior improvements gleaned from the Hawker 800XP.
