Gulfstream Aerospace has delivered its 400th combined G500 and G600.
The milestone aircraft was a G600 outfitted at Gulfstream's St. Louis completions centre. It went to an unnamed customer in the Asia-Pacific region. Gulfstream announced the figure on 20 July 2026, coinciding with the opening day of the Farnborough International Airshow.
The G500 and G600 fleet has now logged more than 519,000 flight hours and over 200,000 landings since entering service. The programme has set more than 190 city-pair speed records. That contribution takes Gulfstream's fleet-wide total to 815.
Mark Burns, president of Gulfstream, said reaching 400 deliveries reflected the continuing confidence customers place in the two aircraft. He described the G500 and G600 as central to the company's vision of an aircraft for every mission. The G500 entered service in 2018. The G600 followed in 2019.
Gulfstream also used Farnborough for the European debut of its next-generation G300 and G400. The in-flight-test G400 flew into the show. A G300 full-scale mock-up appeared alongside static G500, G600, G700 and G800 airframes. Both new platforms sit between the G280 and the ultra-long-range G800 in the line-up.
For G500 and G600 owners, the 400-aircraft mark signals a scaled installed base and a mature service footprint. The two aircraft share the Symmetry Flight Deck architecture with the G700 and G800, easing type transitions inside a mixed Gulfstream fleet.
