Gulfstream Aerospace G450

Name: Gulfstream Aerospace G450
Brand: Gulfstream Aerospace

The G450 modernized the GIV line with a lengthened forward fuselage, the PlaneView cockpit and upgraded Tay engines. Produced from 2005 to 2018, it delivered a 4,350 nm range and Gulfstream's signature large oval windows at a price point well below the G550, and it remains a popular value proposition on the used market.

In short: The Gulfstream Aerospace G450 is a Large Jet with a range of 4,350 nm, a cruise speed of 476 knots and room for 12 passengers. Pre-owned examples trade around $8M–$18M and costs roughly $4,700 an hour to operate (estimate).
