About the Gulfstream Aerospace Gulfstream G650

The Gulfstream G650 is the flagship of Gulfstream Aerospace's ultra-long-range business jet lineup, certified in 2012 after a development program that pushed the boundaries of civilian aircraft performance. It holds the distinction of being the largest-cabin, longest-range purpose-built business jet in production when it entered service, capable of connecting New York to Tokyo or Los Angeles to London nonstop at altitudes up to 51,000 feet. Powered by twin Rolls-Royce BR725 engines, the G650 cruises at Mach 0.85 (516 knots) with a maximum operating speed of Mach 0.925—making it the fastest certified civilian aircraft in its class and one of the few business jets cleared to operate above Mach 0.90.

Its 7,000-nautical-mile range at long-range cruise allows true intercontinental missions with eight passengers, while the 99,600-pound maximum takeoff weight places it at the upper end of the medium wake turbulence category. The G650ER variant, introduced in 2014, extends range to 7,500 nautical miles through increased fuel capacity. The type's combination of speed, range, and cabin volume—over 2,100 cubic feet in a three-zone configuration—has made it the aircraft of choice for heads of state, Fortune 500 flight departments, and fractional operators requiring maximum capability.

Its fly-by-wire flight controls, enhanced vision system, and synthetic vision primary flight display represented a generational leap in business aviation technology when introduced. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
