Gulfstream G300: Buyer’s and investor’s guide
Gulfstream unveiled its new G300 super-mid in September 2025.
Gulfstream’s new G300 is its latest super-midsize model designed to replace the G280 in its “next-generation” fleet.
Unveiled at its Savannah, Georgia base on 30th September 2025, the G300 completes the manufacturer’s goal of “a Gulfstream for every mission”.
The new $28.9m aircraft combines transatlantic range with short-field capability and a range of 3,600nm (6,667km) at Mach 0.80 or 3,000nm (5,556km) at Mach 0.84.
It also claims the longest cabin in its class with two living areas and the capacity to accommodate up to 10 passengers.
“Fuelled by a decade of investment and our future-forward approach, the Gulfstream next-generation fleet offers our customers the most innovative family of aircraft,” said Gulfstream president Mark Burns.
He added: “We know how important the super-midsize cabin segment is to our customers, so building on the highly successful G280 programme, the G300 will re-energize the category with its heightened technology and safety enhancements, alongside the legendary comfort and styling of a Gulfstream.”
Final testing is under way and construction of the second and third aircraft has begun. The aircraft is built in Israel, completed in Dallas, Texas and serviced in Savannah. The first customer delivery is scheduled for the beginning of 2027.
