Gulfstream G300 Super-Midsize Jet Achieves Successful Maiden Flight
Gulfstream Completes Maiden Flight of New G300 Super-Midsize Jet
Gulfstream announced on December 5, 2025, that its highly anticipated G300 super-midsize jet has successfully completed its maiden flight, marking a crucial milestone in the aircraft’s development program and validating years of engineering and design work.
The historic first flight originated from Ben Gurion International Airport in Israel at 8:05 a.m. local time, with the test aircraft returning to the same location approximately two hours later. During the flight, the prototype reached an altitude of 30,000 feet and sustained a speed of Mach 0.75 for 25 minutes, all proceeding nominally according to flight test objectives.
This achievement represents the culmination of extensive preparation, with the prototype undergoing more than 2,000 hours of ground testing prior to taking to the skies. The successful first flight validates Gulfstream’s development approach and sets the stage for an expanded flight test program that will incorporate two additional test aircraft in the coming months.
The G300 represents a significant evolution in Gulfstream’s midsize jet portfolio, designed to replace the venerable G280. Unveiled at a company event in Savannah, Georgia, last September, the new aircraft introduces several notable advancements. Powered by dual Honeywell HTF7250G engines, the G300 can accommodate up to 10 passengers while maintaining a range of 3,600 nautical miles at Mach 0.80 cruise speed, or 3,000 nautical miles when flying at the faster Mach 0.84.
The cabin experience receives particular attention in the G300’s design. According to Gulfstream, the aircraft features the largest interior in its class combined with the lowest cabin altitude, reducing passenger fatigue on longer missions. Additional cabin amenities include a plasma air ionization system for enhanced air quality and Gulfstream’s proprietary Harmony Flight Deck and Predictive Landing Performance System.
The manufacturing partnership between Gulfstream and Israel Aerospace Industries represents a strategic collaboration that leverages IAI’s production capabilities for final assembly in Israel, followed by outfitting at Gulfstream’s completion center in Dallas, Texas. This distributed manufacturing approach optimizes production efficiency while maintaining Gulfstream’s quality standards.
It’s worth noting that while the G300 designation is new to the current market, Gulfstream previously used this name for a short-range variant of its G-IV jet from 2002 until production ended in 2004. The new G300, however, represents an entirely modern platform reflecting current technology and market demands.
With successful first flight validation now achieved, the G300 program moves into the next phase of its development cycle. The introduction of two additional test aircraft will expand the scope of flight testing, enabling Gulfstream to validate performance across a broader envelope and expedite the path to certification.
