New Super-Midsize Gulfstream G300 Takes Flight

Gulfstream Aerospace has commenced the flight test program for its latest aircraft, the Gulfstream G300, after a successful first flight on 5 December 2025. This important achievement highlights the advanced development stage of the super-midsize jet, which was introduced slightly more than two months earlier on 30 September. Set to transform its category, the G300 is a significant enhancement to Gulfstream’s next-generation lineup.

The inaugural flight of the first G300 test aircraft commenced at 8:05 a.m. local time from Ben Gurion International Airport, lasting 2 hours and 25 minutes. Throughout this maiden voyage, the aircraft attained a cruising speed of Mach 0.75 and an altitude of 30,000 feet.

Mark Burns, president of Gulfstream, hailed the achievement, emphasising the aircraft's revolutionary impact on its category. “With its combination of safety, technology, performance and cabin comfort, the G300 is a game changer for the super-midsize category,” said Burns. “This latest investment, designed to exceed our customers’ expectations for large-cabin features in a mid-cabin aircraft, brings another new category leader to our next-generation fleet. With the addition of the G300, Gulfstream truly offers an aircraft for every mission. Achieving first flight at this stage in the program is a remarkable achievement.”

The G300 is poised to be a leader in passenger experience within its segment, boasting the largest interior in the super-midsize category. The roomy cabin can comfortably seat up to 10 passengers across two separate living areas, featuring a well-equipped galley and plenty of baggage space. The ambience is further enriched by natural light pouring in through 10 of Gulfstream's signature Panoramic Oval Windows.

Establishing a new benchmark for passenger comfort, the G300 boasts the lowest cabin altitude in its class at only 4,800 feet (1,463 meters) when flying at 41,000 feet. This is complemented by a 100% fresh air system, a standard plasma air ionisation system, and remarkably quiet sound levels, providing an outstanding and invigorating flight experience.

In addition to comfort, the G300 offers exceptional range and speed capabilities. The aircraft can travel 3,600 nautical miles at Mach 0.80 or extend its high-speed journey to 3,000 nautical miles at Mach 0.84. This remarkable performance is made possible by the combination of Gulfstream’s sleek, swept-wing design and the efficient Honeywell HTF7250G engines, which enhance fuel efficiency.

Safety is of utmost importance in the G300 design, especially in its state-of-the-art Harmony Flight Deck. This sophisticated cockpit features Phase-of-Flight intelligence alongside six user-friendly touchscreens. A key element of the safety suite is the Synthetic Vision-Primary Flight Display, which provides high-quality 3D images of runways and nearby terrain. Additionally, the aircraft includes Gulfstream’s award-winning Predictive Landing Performance System, giving pilots improved awareness and guidance during crucial flight phases.

The successful inaugural flight comes after an extensive preparation period. Before takeoff, the G300 program had accumulated over 2,000 hours of ground testing, highlighting the significant maturity emphasised by the company. The flight test program is strongly supported, with two more test aircraft currently in production, reflecting Gulfstream's strong dedication to a thorough and efficient certification process for the G300. The aircraft is now set to introduce a new standard of large-cabin luxury and super-midsize performance to the global business aviation market.
