G400
G400 at a glance
The Gulfstream G400 flies 4,200 nautical miles nonstop, covering the US coast-to-coast mission and transatlantic crossings such as New York to London, and is the smallest of Gulfstream's new-generation family. The aircraft first flew in August 2024, and certification work continues with an entry-into-service date the manufacturer has not yet announced.
The G400 brings the Symmetry flight deck and the wide G500-derived cabin cross-section into the large-cabin entry class, a segment Gulfstream left when the G450 ended production in 2018. The company is betting that operators of aging mid-size fleets will pay a premium, list price around $34.5 million, for a cabin and cockpit shared with jets three classes above.

Market position
The G400 re-enters a class Gulfstream abandoned, competing with the Challenger 3500 and the top of the Praetor line, and its pitch is simple: the only entry-level large-cabin jet with a flagship cockpit. As Gulfstream looks to pull super-midsize owners up into its family, the G400's shared type-rating path toward the G500 and G600 is the strategic point of the airplane, more than any single specification.
Gulfstream Aerospace, the Savannah, Georgia-based business jet unit of General Dynamics, has been building large-cabin jets since the Gulfstream II of 1966 and delivers from final assembly lines in Savannah and Appleton, Wisconsin.
