Gulfstream Aerospace G400

Twin Jet

The Gulfstream G400 represents the latest evolution in the storied lineage of mid-cabin business jets from Savannah, bridging the gap between the smaller G280 and the flagship ultra-long-range G650. Launched in 2018 and certified in 2023, the G400 replaced the earlier G350 and G450 models with an all-new design featuring Pratt & Whitney Canada PW812D engines, advanced fly-by-wire flight controls, and the Symmetry Flight Deck derived from Gulfstream's military programs. The aircraft delivers a maximum range of 4,200 nautical miles at Mach 0.85, enabling nonstop city pairs like New York to London or Los Angeles to Hawaii, while maintaining the signature Gulfstream oval windows and low cabin altitude that have defined the brand since the 1960s. What sets the G400 apart in the crowded large-cabin market is its combination of speed, range, and operating economics. With a maximum cruise speed of Mach 0.85 and a ceiling of 51,000 feet, it matches or exceeds most competitors while burning less fuel than the legacy G450 it replaced. The cabin accommodates up to 12 passengers in typical configurations, with Gulfstream's signature 100-percent fresh air system cycling the entire cabin volume every two minutes. The aircraft's advanced wing design and powerful engines enable steep approaches into challenging airports like Aspen and Lugano, expanding operational flexibility for fractional operators and corporate flight departments. Since entering service, the G400 has found favor with fractional ownership providers and high-net-worth individuals seeking a balance between transcontinental range and operating costs. The type competes directly with the Bombardier Global 5500 and Dassault Falcon 6X in the large-cabin segment, though Gulfstream's reputation for dispatch reliability and residual values continues to command premium pricing. SkyMeter has tracked 24 flights across 1 airframes and 1 operators, with NETJETS SALES INC the largest observed operator.
