It's also the fastest certified civilian aircraft, reaching an average speed of 568.5 miles per hour.
To prove it, Gulfstream took the G650 on a record-setting flight, circling the globe in just 41 hours, 7 minutes.
That's the fastest time for a westbound flight to circle the globe in a non-supersonic aircraft.
The National Aeronautic Association (NAA) and the Fédération Aéronautique Internationale recognized the record in September.
Gulfstream's president Larry Flynn called it a momentous occasion for business aviation, showing off both the speed and range of the G650.
"The aircraft performed flawlessly," pilot-in-command Tom Horne said in a Gulfstream press release.
Covering 20,310 nautical miles, the G650 started and ended its around-the-world flight in San Diego, with stops in Guam, Dubai and Cape Verde. Five pilots shared the journey.
