First Flight of the all-new Gulfstream G300 redefines expectations and marks the start of an ambitious new chapter in Super-Midsize Business Jets

On December 5, 2025, Gulfstream Aerospace Corporation proudly announced that its brand-new Gulfstream G300 super-midsize business jet had successfully completed its first flight, a defining moment in the aircraft’s development and a key milestone for Gulfstream’s next-generation fleet.
Departing Ben Gurion International Airport in Israel at 8:05 a.m. local time, the G300 prototype remained airborne for 2 hours and 25 minutes, reaching an altitude of 30,000 feet and cruising at Mach 0.75 before returning safely to its departure field. This inaugural flight demonstrated the maturity of the programme and officially launched the aircraft’s flight test campaign — a structured series of evaluations that will lead toward certification and entry into service.
A NEW BENCHMARK IN THE SUPER-MIDSIZE SEGMENT
Gulfstream characterises the G300 as a significant evolutionary step for the super-midsize category, integrating the company’s latest design, technology and comfort achievements. The aircraft will feature signature Gulfstream Panoramic Oval Windows as well as an all-new Harmony Flight Deck, which includes next-generation avionics to enhance safety and operational efficiency.

Introduced to the world on September 30, 2025 at Gulfstream’s Savannah, Georgia headquarters, the G300 is intended to succeed the highly successful Gulfstream G280 and elevate expectations for performance, avionics and cabin experience. At its core, the G300 is engineered to serve the demanding missions typical of super-midsize operators — those who require intercontinental range, efficient performance, advanced avionics and a premium cabin environment, all within a versatile and cost-effective package.
DESIGN AND TECHNICAL ATTRIBUTES
From the outset, Gulfstream emphasised that the G300 embodies its “visionary fleet” philosophy: a family of aircraft that blends innovation with proven engineering principles across all size classes.
The G300’s airframe and systems are designed to deliver a compelling mix of distance capability and operational flexibility:
“WITH ITS COMBINATION OF SAFETY, TECHNOLOGY, PERFORMANCE AND CABIN COMFORT, THE G300 IS A GAME CHANGER FOR THE SUPER-MIDSIZE CATEGORY”
—MARK BURNS, PRESIDENT, GULFSTREAM
AVIONICS AND PILOT-CENTRIC INNOVATION
Central to the G300’s cockpit philosophy is the Harmony Flight Deck, Gulfstream’s latest avionics suite designed to enhance situational awareness, ease of operation and safety. The aircraft’s navigation and control systems are expected to feature highly intuitive interfaces, integrated automation and advanced predictive tools that streamline pilot workload and decision-making.
This approach builds on Gulfstream’s established strategy of offering cutting-edge avionics that not only meet but often exceed regulatory and customer expectations in business aviation, contributing to operational consistency across the Gulfstream fleet.
CABIN COMFORT AND PASSENGER EXPERIENCE
Passenger experience sits at the heart of the G300’s design. Gulfstream’s official material highlights the aircraft’s cabin environment as a defining strength of the programme:

These elements collectively reflect Gulfstream’s longstanding commitment to setting premium standards in cabin design, where comfort, aesthetics and passenger well-being are integral to the overall experience.
MARKET POSITIONING AND TARGET CUSTOMERS
As the successor to the G280, the G300 is positioned to attract a broad cross-section of super-midsize business jet buyers:
The G300 targets a segment where aircraft must balance size, operational efficiency and premium service quality — a balance that Gulfstream aims to achieve through its integrated design and technology choices.
BUILDING ON THE HIGHLY SUCCESSFUL G280 PROGRAMME, THE G300 WILL REENERGISE THE CATEGORY WITH ITS HEIGHTENED TECHNOLOGY AND SAFETY ENHANCEMENTS, ALONGSIDE THE LEGENDARY COMFORT AND STYLING OF A GULFSTREAM—MARK BURNS, PRESIDENT, GULFSTREAM
PATH TO ENTRY INTO SERVICE
Following its first successful flight, Gulfstream’s next major objective is to carry the G300 through its flight test programme, a comprehensive process that will validate performance, safety and reliability across all phases of operation. Successful certification will pave the way for customer deliveries, currently anticipated in 2027.
The deployment of additional test aircraft will accelerate data collection and fine-tuning, ensuring the G300 meets both regulatory requirements and customer expectations.
CONCLUSION: A STRATEGIC LEAP FORWARD
The first flight of the Gulfstream G300 stands as a testament to Gulfstream Aerospace’s enduring commitment to innovation within business aviation. With its combination of trans-continental range, advanced avionics, refined cabin environment and rigorous development process, the G300 is poised to become a compelling choice in the competitive super-midsize segment.
As the programme transitions from early flight testing to certification and customer delivery, industry observers and prospective operators will be watching closely to see how Gulfstream’s new entrant reshapes expectations for performance, comfort and operational excellence in its class.
