Gulfstream Introduces G300: The Next-Gen Super-Midsize Jet to Replace the G280

With 3,600 nm range, advanced avionics and elevated comfort, Gulfstream’s G300 aims to reshape the super-midsize segment

Gulfstream Aerospace has unveiled the G300, a new super-midsize business jet designed to succeed its current G280 model. The announcement marks Gulfstream’s continued push to modernize its product line with enhanced performance, technology, and passenger comfort.

Why the G300? Replacing the G280 with a Next-Generation Platform

• The G280 has been a strong performer in Gulfstream’s midsize portfolio, but Gulfstream sees room to advance its capabilities.
• The G300 is intended as a full replacement: Gulfstream positions it as the successor to the G280 with a design refresh, new systems, and upgraded performance.
• With the G300, Gulfstream aims to “re-energize the category” by combining safety, efficiency and the hallmark Gulfstream cabin experience.

Performance & Range: Eyes on 3,600 Nautical Miles

• Gulfstream puts the G300’s range at 3,600 nm (6,667 km) when cruising at Mach 0.80.
• At a higher cruise speed of Mach 0.84, the range is estimated at 3,000 nm.
• The G300 will cruise up to 45,000ft, and Gulfstream claims it will deliver the lowest cabin altitude in its class (equivalent to ~4,800 ft) to enhance passenger comfort. Gulfstream also emphasizes “short-field agility” and trans-Atlantic capability as part of the aircraft’s mission envelope.

Avionics & Systems: The Harmony Flight Deck

• The G300 introduces the new Harmony Flight Deck, with six touchscreen displays and several advanced pilot support systems.
• Among its features are synthetic vision 3D runway/terrain displays and a Predictive Landing Performance System to help pilots manage runway overrun risk.
• Its avionics draw lineage from the “Symmetry Flight Deck” used in Gulfstream’s larger aircraft, promising a degree of familiarity and transition ease for pilots moving between models.

Cabin, Comfort & Layout

• The G300 retains Gulfstream’s signature Panoramic Oval Windows, now expanded in the new cabin.
• The aircraft offers two living areas and configurations for up to 10 passengers.
• Gulfstream emphasizes a quiet, healthy cabin with 100 % fresh air, a plasma ionization purification system, and optimized pressurization to reduce fatigue.

Development Progress, Testing & Timeline

• Gulfstream reports having conducted ~22,000 hours of testing in its integration test and laboratory facilities, including simulations and “iron bird” systems.
• For the initial G300 aircraft, nearly 2,000 ground-test hours have already been logged, and two additional test airframes are in ongoing manufacturing.
• Gulfstream has not publicly committed to a first flight date or a formal entry-into-service timeline, citing safety and certification uncertainties.
• A starting price was mentioned in some coverage: US $28.7 million (approx.) for base configuration.

Strategic Implications & Market Positioning

• With the G300, Gulfstream seeks to solidify its offering in the super-midsize class where competitors like Bombardier, Embraer, and Cessna also focus.
• The combination of trans-Atlantic reach, short-field performance, and advanced avionics could give the G300 a competitive edge in demanding mission profiles.
• The replacement of the G280 with a fully modernized platform may help Gulfstream better manage obsolescence, streamline support, and renew customer interest.
• For current G280 owners or prospective buyers, the G300 offers a clear upgrade path while retaining cabin appeal and Gulfstream design language.

Conclusion

The launch of the Gulfstream G300 signals a major step forward in the company’s super-midsize strategy. With its ambitious range, cutting-edge flight deck, and refined cabin, Gulfstream is betting the G300 will raise the bar for performance and passenger experience inits class.
