The Hawker 400 is a small twinjet corporate aircraft. Initially designed and built by Mitsubishi, it has been further developed and updated by the Beech Aircraft Company, now part of Textron Aviation.


It 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 minimize drag. Its two Pratt & Whitney Canada JT15D turbofans are mounted on the rear fuselage.

Powered by JT15D-5/-5R, it can fly 1,351 nm with four passengers, cruising at Mach 0.71–0.73, and most pilots are comfortable flying it over three hours, about 1,175 nmi cruising at Mach 0.73–0.76, typical missions are 1.5 to 2.0 hours with 400 kn block speeds. It burns 1,500 lb of fuel the first hour, dropping to 1,100–1,200 lb for the second. Basic operating weights range from 11,000 to 11,100 lb, full tanks payload is less than 500–600 lb but the average passengers are three, it can fly six passengers 1,100 nmi.


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.

Nextant Aerospace re-manufactures it as the 400XT, replacing the JT15Ds with Williams FJ44s and adding new avionics and interior, it was FAA-certified in October 2011.[12] Up to one-third of the 400A/400XP fleet could be retrofitted, enabling improved range, speed and fuel efficiency. It should keep their resale value to remain in economic service for another twenty to thirty years, like Falcon 20s reengined with TFE731s.

Beechcraft Model 400A Beechjet (1992-2002) Serial Numbers RK2 through RK353

Upgraded model, initially produced as the Beechcraft Beechjet 400A, then Raytheon Beechjet 400A, then Raytheon Hawker 400XP, then Hawker Beechcraft Hawker 400XP. One prototype converted from Model 400 and 593 built as of the end of 2009.

Model 400T

Military version of the Model 400A, 180 built for the United States Air Force as the T-1 Jayhawk and 13 built for the Japan Air Self-Defense Force. In Japanese service they are referred to as T-400.

Beechcraft Model 400XP Beechjet / Hawker 400XPR (2003-2010) Serial Numbers RK354 through RK604

A factory engineered and supported upgrade first flown May 2012. The conversion features new avionics, interior, winglets, and Williams FJ44-4A-32 engines. The first fully configured was delivered on July 20, 2017, the upgrade can be performed in 12 weeks with a choice of Rockwell Collins Pro Line 4 to 21 or Garmin G5000 avionics, it provides 33% more range to 2,160 nmi with four passengers, better hot and high performance and a 19 min climb to FL450 at max takeoff weight.
