Gulfstream Aerospace’s G450 is a large-cabin business jet developed by the Savannah, Ga., manufacturer. From a design standpoint, it is a derivative of Gulfstream’s GIV airframe. While the G450 was derived from that airframe, it bears a new type designation (GIV-X) that it shares with the lower-weight and lower-fuel-capacity G350.

Among the changes that were certified on this second-generation airframe were upgrades in avionics, propulsion and aerodynamics.

Currently, the G450 is the only in-production derivative of the Gulfstream GIV. As of mid-2016, more than 350 G450s had been delivered from Gulfstream’s Savannah facility. However, that production will come to an end in early 2018, when the company delivers the final G450 and turns its focus to the all-new G500.
