Gulfstream Takes Wraps Off Super-midsize G300

Gulfstream Aerospace launched the G300, a $28.9 million derivative of the super-midsize G280, this morning during a customer event at its Savannah, Georgia headquarters. Notably, the long-rumored new model has 10 Gulfstream-signature panoramic cabin windows and Honeywell Epic 2-based “Harmony” avionics. During the event, Gulfstream president Mark Burns revealed a full-scale mockup of the G300 and showed photos of the first aircraft in production in Tel Aviv, where IAI manufactures super-midsize jets under license for Gulfstream.

To date, nearly 22,000 hours of ground testing on the G300 have been conducted at Gulfstream’s lab facilities, including an integration test facility with iron bird capability. That facility also completed a virtual first flight last month. Meanwhile, nearly 2,000 ground test hours have been logged on the first aircraft, which is “being prepared for first flight,” a company spokeswoman told. In addition, IAI has begun manufacturing two more test aircraft. Gulfstream has not provided an estimate for service entry, but industry sources point to first-half 2028 for initial deliveries.

Besides structural changes needed to accommodate the larger cabin windows, the avionics switch from the G280’s Collins Pro Line Fusion to a Honeywell system denotes the biggest certification hurdle for the G300. Specifications and performance include 3,600-nm range at Mach 0.80; 45,000-foot ceiling; and 4,800-foot cabin altitude at FL410. Its two-zone cabin can seat up to 10 passengers. Courtesy of AIN.
