The 400XP has a long pedigree, beginning with its origin as a Mitsubishi Diamond jet. It was acquired by Beechcraft and later rebranded as a Hawker, while the design was continually tweaked and updated. The XP strikes a balance between speed, comfort, and value popular with charter and fractional operators as well as private owners and corporate flight departments. The swept wing adds to high cruise speeds, and the squared-oval cabin shape maximizes head and shoulder room. Internal baggage space provides access to essentials in flight, while an external cargo bay holds up to six sets of golf clubs plus bags.
