Gulfstream G300 Super‑Midsize Jet Unveiled

On October 2, 2025 Gulfstream unveiled the Gulfstream G300, a super-midsize business jet set to replace the G280.

The G300 introduces a package of upgrades aimed at corporate flight departments and charter operators across the United States and Europe, with Gulfstream highlighting improvements in range, cabin comfort and avionics. The company positioned the model to compete in the high end of the super-midsize segment while maintaining Gulfstream’s emphasis on long-range performance and cabin experience.

Gulfstream said deliveries will begin once the G300 completes certification; a formal timeline for certification milestones was not provided in the announcement. The G300 replaces the G280 in Gulfstream’s product lineup, reflecting the company’s ongoing investment in next-generation business aviation platforms.

What the Gulfstream G300 brings

The new model focuses on three priorities: more usable range compared with the outgoing G280, a quieter and more comfortable cabin layout for passengers, and modernized avionics to improve crew situational awareness. Gulfstream is pitching the G300 to corporate users and charter operators who need regional-to-transatlantic flexibility without stepping up to ultra-long-range aircraft.

Replacement model: the Gulfstream G300 will replace the G280 in Gulfstream’s lineup.
Target markets: corporate flight departments and charter operators in the US and Europe.
Key upgrades: enhanced range, improved cabin comfort and updated avionics.
Delivery plan: Gulfstream expects deliveries to begin after regulatory certification is complete.

The announcement underscores Gulfstream’s strategy of iterative platform updates rather than radical redesigns — improving what customers value most while keeping operational commonality for operators that already fly Gulfstream twinjets. More technical specifications and a certification schedule are expected to follow in Gulfstream’s formal release cycle.
