The Gulfstream G450 is a direct descendent of the Gulfstream G400/GIV-SP series. It comes with upgraded engines (Rolls-Royce Tay 611-8C) with FADEC, and redesigned thrust reverser, nacelle and pylon that, coupled with aerodynamic improvements, increase range and payload. It was designed using the G400 airframe with the G550 nose section grafted on, and the fuselage is 12 inches longer than the Gulfstream IV.
As of May 2021, 60% of all Gulfstream G450 aircraft were purchased pre-owned by their current owners, the other 40% new. 7.3% are for sale with the majority of those (92%) under an exclusive broker agreement. When for sale the average time on the market is 288 days.
In 2001 Gulfstream began working on the Gulfstream G450 model, an improved version of the GIV-SP. Flight-testing of the Gulfstream G450 started in April 2003 and FAA certification was completed in August 2004. The Gulfstream G450 entered service in May 2005 and production ended in January 2018.
There are 354 Gulfstream G450 aircraft in operation today. The majority of those (323) are wholly owned with 8 in shared ownership and 23 in fractional ownership. 12% are currently leased. North America has the largest percentage of wholly owned Gulfstream G450 aircraft (67%), followed by Asia (23%) and Europe (7%).
