The Gulfstream G450 is an upgrade from the Gulfstream IV (G4 / GIV) and was approved by the FAA in August of 2004. After approximately 14 years in production, Gulfstream has shipped more than 360 aircraft before shifting their focus towards the G500.
Despite the upgrade, the G450 has a number of similarities to the GIV. However, it does incorporate many aspects of the GV as well. For example, the nose of the aircraft was modeled very similar to the G550. Along with that, the GV’s automated pressurization and electrical systems have also been included.
