Gulfstream Aerospace has achieved a milestone with its G600/G500 series, logging the 300th delivery of the large-cabin business jets. The G500 achieved FAA certification in 2018, followed by approval for its larger sibling a year later, with both models being issued with their type and production certificates simultaneously.

The aircraft were purposely designed to increase manufacturing efficiencies through commonality with the rest of the Savannah, Georgia-based OEM’s new models—the G400, G700, and G800—that feature the Honeywell Epic-based Symmetry flight deck.

Both the G500 and G600 are powered by Pratt & Whitney Canada PW800 engines and feature a maximum operating speed of Mach 0.925. At Mach 0.85, the former has a range of 5,300 nm while the latter model can fly 6,600 nm.

In June the two aircraft families each surpassed 100,000 flight hours and within the past year both received FAA certification for steep approach operations.

“Delivering 300 aircraft is a clear indication of strong interest in the G500 and G600 around the world,” said Gulfstream president Mark Burns, adding the advanced efficiencies established by this program have provided flexibility to expand the airframer’s production line and support the success of its next-generation fleet well into the future. “Thanks to investments from our parent company, General Dynamics, these aircraft continue to achieve new milestones as customer demand remains steadfast.”
