Gulfstream has officially unveiled its newest business jet, the G300, marking the company’s return to the modern super-midsize category. The G300 is set to replace the long-serving G280 in Gulfstream’s lineup, bringing new levels of cabin comfort, range, and avionics to this highly competitive market. Gulfstream is positioning the G300 as a fresh alternative for operators looking for transcontinental performance in a smaller, more efficient package—one that still offers the signature oval windows, cabin quietness, and long-range capability associated with the brand.
In terms of market competition, the G300 enters the super-midsize jet segment, where it will go head-to-head with aircraft like the Bombardier Challenger 3500, Embraer Praetor 600, and Cessna Citation Longitude. Gulfstream aims to stand out with what it claims is the longest cabin in its class, along with more advanced avionics and better fuel efficiency. For current Gulfstream operators, the G300 provides a sense of continuity with common systems and design language that align with the company’s larger jets.
The G300 is designed to fly up to 3,600 nautical miles at Mach 0.80 with four passengers and NBAA IFR reserves. Its maximum operating speed is Mach 0.85, and it can cruise at altitudes up to 45,000 feet. The aircraft features takeoff distances under 4,800 feet and supports up to 10 passengers across two cabin zones. It is powered by a pair of Honeywell HTF7250G engines, each delivering approximately 33.9 kN of thrust.
Among the key innovations in the G300 is the new Harmony Flight Deck, which includes six large touchscreen displays, synthetic vision, a predictive landing performance system, and Gulfstream’s latest phase-of-flight interface design to streamline pilot workload. The cabin includes 100% fresh air, plasma ionization air purification, and an ultra-low cabin altitude of around 4,800 feet at cruising levels. The aircraft’s wing design and engine pairing also contribute to significant fuel-efficiency improvements, helping operators reduce costs and emissions.
Gulfstream reports that development of the G300 is well underway, with over 22,000 hours of lab testing already completed and multiple flight test aircraft under construction. Taxi tests have begun on the first prototype, and first flight is expected soon. Certification and customer deliveries are targeted for 2027, pending a successful flight test program and regulatory approval. Once in production, the G300 will be assembled by partner Israel Aerospace Industries (IAI) in Tel Aviv. Cabin outfitting will take place at Gulfstream’s Dallas facility.
