The Gulfstream G600, certified in 2019, is the ultra-long-range sibling of the G500. Sharing the same Symmetry Flight Deck and cabin cross-section, the G600 extends the fuselage by approximately 1 meter and carries additional fuel for a range of 12,038 km — sufficient for nonstop flights between virtually any major city pair.

The G600 fills the gap between the G500 and the larger G650ER, offering ultra-long-range capability in a more cost-effective package. Its three living areas, low cabin altitude, and 100% fresh air make it ideal for long overnight crossings where passenger comfort directly impacts productivity at arrival.

The G600 cabin extends to 13.66 m in length, enabling three distinct living areas: a forward conference/dining zone, mid-cabin lounge, and aft rest area with divan convertible to a bed. The full-size forward galley can prepare multi-course catering for overnight flights.

The cabin altitude at maximum cruise altitude of 51,000 ft is approximately 1,310 m — the lowest in business aviation. Combined with 100% fresh air, this dramatically reduces fatigue and jet lag on transcontinental and intercontinental flights.

The G600 competes with the Bombardier Global 6500, Dassault Falcon 8X, and the Gulfstream G550 (pre-owned). Against the Global 6500, the G600 offers a more modern flight deck and lower cabin altitude, while the Global counters with a wider cabin. Against the Falcon 8X, the G600 offers greater range and speed.
