Gulfstream announced at the annual European Business Aviation Association exhibition, that it had developed an extended range version of the G650 called the G650ER. The G650ER is capable of flying 7,500 nautical miles (13,900 km; 8,600 mi) at Mach 0.85, due to its 4,000 pounds (1,814 kg) increase in fuel capacity and carry between 11 and 18 passengers. The extra fuel is housed in existing space inside the G650's wings and aircraft already built may be quickly upgraded to the ER version. The G650ER received its certification in October 2014 and began deliveries in late 2014 ahead of its 2015 target.
The Gulfstream G650ER has a range of 7,437 nautical miles. Type in your city or airport identifier for a visual representation of the NBAA IFR Range (NM) for this aircraft.
