Hawker 400XPThe History behind this Exclusive Jet
The aircraft was originally designed as the Mitsubishi MU-300 Diamond, an all-new, all-jet development to complement and slot above the Mitsubishi MU-2 and provide Mitsubishi Heavy Industries with their top-of-the-line corporate aircraft model (hence the name “Diamond”). It first flew on August 29, 1978. Mitsubishi went on to produce 97 MU-300s, all of which were assembled by the company’s United States subsidiary.
In 1985 Mitsubishi sold the rights and a number of unfinished airframes to Beechcraft, who began manufacturing it as their own model, initially re-designated as the Beechjet 400, certificated by the Federal Aviation Administration in May 1986. Raytheon/Beechcraft developed improvements for the 1990 400A for longer range, higher take-off weights, luxury appointments and offering an all-glass flight deck.
Beechcraft developed the T-1 Jayhawk version for the United States Air Force, used as a trainer for crew of large aircraft like tankers and strategic transports: 180 were delivered between 1992 and 1997. The Japan Air Self-Defense Force 400T trainer shares the T1-A Type certificate.
In 1993 Raytheon purchased the Hawker business jets from British Aerospace, renamed the Beechjet 400 as the Hawker 400 to include it in the line and the Hawker 400XP incorporated aerodynamic, mechanical and interior improvements from the Hawker 800XP. In October 2008, Hawker Beechcraft upgraded it as the Hawker 450XP including new, more fuel efficient Pratt & Whitney PW535Ds with 2,965 pounds of thrust each but it was canceled in June 2009 due to poor economic conditions.
The Hawker 400XP is a small, low-winged twin-turbofan aircraft of all metal construction, flown by a crew of two pilots and accommodating eight passengers in a pressurized cabin. Its wings use a computer designed, supercritical airfoil in order to minimise drag. Its two Pratt & Whitney Canada JT15D turbofans are mounted on the rear fuselage.
Powered by JT15D-5/-5R, it can fly 1,351 nmi (2,502 km) with four passengers, cruising at Mach 0.71–0.73, and most pilots are comfortable flying it over three hours, about 1,175 nmi (2,176 km) cruising at Mach 0.73–0.76, typical missions are 1.5 to 2.0 hours with 400 kn (740 km/h) block speeds. It burns 1,500 lb (680 kg) of fuel the first hour, dropping to 1,100–1,200 lb (500–540 kg) for the second. Basic operating weights range from 11,000 to 11,100 lb (4,990 to 5,030 kg), full tanks payload is less than 500–600 lb (230–270 kg) but the average passengers are three, it can fly six passengers 1,100 nmi (2,000 km).
Comfort & Size
The cabin of the 400XP is more spacious thanks to the aforementioned refinements. Carrying 7 or 8 passengers and a crew of two, the interior dimensions measure: 15.6 ft long, 4.8 ft high and 4.9 ft wide.
Passengers enjoy seats that swivel up to 180 degrees. A cabin baggage area and refreshment cabinet have been added. Newly located engine mounts and the addition of sound-dampening materials allows for a much more enjoyable and quieter cabin environment.
As with every feature in this jet, the attention to detail in its design is apparent. The cabin has a flat floor and an oval shape, maximizing the amount of usable space. Its internal and external baggage space totals fifty-three cubic feet. It holds seven passengers comfortably in a seating arrangement that has been redesigned since the previous model. Although many of the exact details of its design slip by clients unnoticed, no one can avoid enjoying the experience of flying in the truly classy cabin of the Hawker 400XP.

With such strong design features, it is not surprising that the Hawker 400XP roots back to the basis for the military T-1 Jayhawk tanker and transport aircrew trainer. 180 of the T-1 Jayhawks were delivered between 1992 and 1997 for military training. The 400A has been continuously redesigned, and has now evolved into Raytheon’s successful Hawker 400XP. With such successful pedigree it is no surprise that the 400XP remains a strong contender in its class, and is ideal for corporate or individual travel.
