Both the Global 6000 and the Global 5000 have the exact same cabin height and width, but the Global 6000’s 48.35-foot length is nearly 6ft longer than the Global 5000’s. The Gulfstream G650 has the greatest length of the study group at 53.6 feet.
The Gulfstream G600 was unveiled on the 14th of October, 2014. It was introduced as the successor to the G550, which had a production run of 600 units, making it the top-selling inter-continental business jet globally. A feat that the company expects the G600 to match. To set it up for success, Gulfstream has given the G600 a larger footprint wPNcOW2.
