The New Gulfstream G300: Redefining the Super-Midsize Segment

Gulfstream Aerospace has revealed the Gulfstream G300, a super-midsize business jet designed to succeed the G280 and set a new benchmark in its class. With trans-Atlantic range, short-field capability, and an interior that reflects Gulfstream’s legacy of comfort, the G300 is positioned to reshape expectations in the midsize-to-super-midsize category.

Performance and Range

The G300 blends speed, range, and efficiency with advanced aerodynamics and next-generation engines:

• Range: 3,600 nm (Mach 0.80) or 3,000 nm (Mach 0.84)
• Maximum Cruise Altitude: 45,000 ft
• Cabin Altitude: 4,800 ft at 41,000 ft — the lowest in its class
• Engines: High-thrust Honeywell turbofans paired with Gulfstream’s clean, swept wing

These performance numbers make the G300 capable of crossing the Atlantic while maintaining strong runway performance for shorter missions into challenging airports.

Cabin Experience

Gulfstream emphasizes passenger wellness and productivity:

• Longest cabin in its class, accommodating up to 10 passengers
• Two distinct living areas for work and relaxation
• Panoramic oval windows for natural light and expansive views
• Fresh air and plasma ionization purification system for a cleaner cabin environment
• Noise-reduction technology and ergonomically designed seating

The cabin is designed to minimize fatigue and maximize comfort on long-haul flights, while still being practical for shorter domestic missions.

Flight Deck and Avionics

The Harmony Flight Deck introduces Gulfstream’s most advanced avionics suite yet:

• Six touchscreens with Phase-of-Flight intelligence for intuitive pilot workflows
• Synthetic Vision-Primary Flight Display with 3D terrain and runway imaging
• Predictive Landing Performance System that dynamically calculates runway stopping points in real time

These technologies enhance situational awareness, reduce pilot workload, and improve safety margins in challenging conditions.

Development and Testing

The G300 program reflects Gulfstream’s decade-long investment in its next-generation fleet. Key milestones include:

• 22,000 hours of testing completed across lab and integration facilities
• The Iron Bird full-scale structural mock-up has already logged nearly 2,000 ground test hours
• Taxi tests underway, with three aircraft currently in production

Final assembly and completions will be carried out in Dallas, Texas, while servicing and support will be based in Savannah, Georgia. The first customer delivery is expected in early 2027, with a list price near $28 million.

Market Context

The G300 directly targets a crowded market segment that includes the Bombardier Challenger 3500 and Cessna Citation Longitude. Gulfstream’s edge lies in:

• Greater range than many competitors
• Lower cabin altitude for passenger health and comfort
• Brand prestige and a reputation for long-term residual value

Mark Burns, President of Gulfstream, underscored this positioning:
“We know how important the super-midsize cabin segment is to our customers, so building on the highly successful G280 program, the G300 will re-energize the category with heightened technology and safety enhancements, alongside the legendary comfort and styling of a Gulfstream.”

Outlier’s Perspective

For our jet card members and clients evaluating aircraft ownership, the Gulfstream G300 represents an intriguing option. It’s built for versatility — equally suited for short-field operations into airports like Aspen or Telluride as it is for trans-Atlantic travel between New York and London.

As with any new aircraft program, timelines and performance claims will evolve, but the G300 signals Gulfstream’s commitment to the super-midsize category. For those considering ownership or long-term access, our team at Outlier sees the G300 as a model worth tracking closely in the years leading up to its entry into service.
