Georgia-based manufacturer showcases super-midsize aircraft with transatlantic range and advanced cockpit technology at Savannah headquarters
Gulfstream Aerospace revealed its latest business jet late last month, introducing the G300 as a successor to the company’s G280 model.
The aviation manufacturer displayed a full-scale mock-up of the super-midsize aircraft during an invitation-only customer gathering at its Savannah, Georgia facility on Sept. 30, 2025.
“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,” company president Mark Burns said during the unveiling event.
The company hasn’t announced target dates for the aircraft’s maiden flight or when customers can expect deliveries.
Performance and capacity
The G300 will carry 10 passengers plus crew members, flying 3,600 nautical miles at Mach 0.80 or covering 3,000 nautical miles at the faster Mach 0.84 speed. At maximum range, the jet can reach destinations like Abuja, Nigeria; Dubai in the United Arab Emirates; and New York from London, according to company route maps.
The aircraft requires just 4,780 feet of runway for takeoff and climbs to a maximum altitude of 45,000 feet. With a maximum takeoff weight of 39,750 pounds, the jet carries up to 3,820 pounds of payload.
Twin Honeywell HTF2570G turbofan engines will power the aircraft, which Gulfstream says combines “transatlantic range with short-field agility.”
Cabin features and air quality
Ten signature Panoramic Oval Windows dot the fuselage, a design element Gulfstream describes as streaming “abundant natural light into a spacious, refined environment.”
The cabin ventilation system circulates 100% fresh air and employs plasma ionization technology to purify the air inside the aircraft.
Advanced flight deck technology
Six touchscreens dominate the Harmony Flight Deck, paired with what the company calls “phase-of-flight intelligence” to simplify pilot controls during different stages of flight.
A synthetic vision primary flight display renders runways and terrain in three-dimensional images, helping pilots maintain better situational awareness. The cockpit also features Gulfstream’s Predictive Landing Performance System, which shows the runway stopping point in real time as conditions change.
“With an ideal combination of size, advanced avionics and aerodynamic design, the G300 is primed for fast, efficient flight with its high-thrust Honeywell engines, coupled with the clean, swept Gulfstream wing to support fuel-efficiency,” the company said in a statement.
Testing already underway
Gulfstream disclosed the G300 is already deep into development work. The first aircraft had logged nearly 2,000 ground test hours by late September at the company’s Integration Test Facility in Savannah.
Using static “iron bird” testing equipment, the G300 completed what the manufacturer called its “first flight” in August 2025, though the aircraft remained on the ground during these evaluations.
“The G300 programme is making great progress and the vision for this aircraft is well on its way to becoming a reality for our customers as they look for an aircraft that will exceed their expectations in the super-midsize class,” Burns said.
Two additional G300 aircraft are now under construction for flight testing, according to the company.
Product line positioning
The G300 sits at the entry level of Gulfstream’s current business jet lineup, offering the shortest range and smallest passenger capacity in the fleet.
The next step up, the G400, accommodates 12 passengers and flies up to 4,200 nautical miles. That model completed its first flight from Savannah on Aug. 15, 2024.
Two larger models, the G500 and G600, each seat 13 passengers and offer ranges of 5,300 and 6,600 nautical miles respectively. The G700, also configured for 13 passengers, extends the range to 7,750 nautical miles.
The G800 tops the lineup with capacity for 15 people and an 8,200-nautical-mile range. Gulfstream delivered its first customer G800 to an undisclosed buyer on Aug. 27, 2025, following Federal Aviation Administration and European Union Aviation Safety Agency certifications on April 16, 2025.
Gulfstream says it “offers an aircraft for every mission” in business aviation, with more than 3,300 of its aircraft currently operating worldwide.
