[4] The aircraft can be configured to carry from 11 to 18 passengers over a range of 7,000 nautical miles [nmi] (13,000 km; 8,100 mi) at a top speed of Mach 0.925 (530.6 kn; 982.7 km/h; 610.6 mph).

The G650ER is an extended-range version of the G650, adding about 500 nmi (930 km; 580 mi) by modifying the fuel system, an upgrade offered for existing G650 aircraft.

Introduced in October 2019, the G700 stretched the airframe by 10 feet (3.0 m) and increased its top speed to Mach 0.935 (536.3 kn; 993.3 km/h; 617.2 mph) using a new wing and improved Rolls-Royce Pearl 700 engines.

At the public announcement occasion, company executives stated the new model would become Gulfstream's largest, fastest and most expensive business jet on entry to the market.

[15] Gulfstream reported on August 26, 2010, that the G650 hit a maximum speed of Mach 0.995 during a dive as part of its 1,800-hour flight test program.

[24] Also in May 2014, Gulfstream confirmed that the G650 would be offered to the United States Air Force for its program to replace the E-8C JSTARS air-to-ground surveillance and targeting aircraft.

[25] However, during the fiscal 2019 budget rollout briefing it was announced that the Air Force will not move forward with an E-8C replacement aircraft.

Funding for the JSTARS recapitalization program will instead be diverted to pay for development of an advanced battle management system.

[26][27] In September 2018, Gulfstream was conducting testing at London City Airport to certify the aircraft to perform steep approaches.

[29] On May 18, 2014, Gulfstream announced at the annual European Business Aviation Association exhibition, that it had developed an extended range version 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.

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.

[31] The same year, a G650ER set a new record for the longest non-stop flight by a purpose-built business jet, flying 8,010 nautical miles (14,835 km; 9,218 mi) from Singapore to Las Vegas with four passengers and crew.

[33] On the eve of the October 2019 NBAA Convention & Exhibition in Las Vegas, Gulfstream announced its new flagship, the G700, showing a video of the aircraft taxiing under its own power in Savannah.

[36] The G700 should share its fly-by-wire cockpit with the G500/G600: active control sidesticks and Honeywell Primus Epic flight deck with synthetic and enhanced vision systems for a common type rating.

[40][41] On April 23, 2024, Gulfstream began customer deliveries of its new G700 aircraft, less than a month after obtaining Federal Aviation Administration (FAA) certification.

It can be equipped with a full kitchen and bar as well as a variety of entertainment features including satellite telephones and wireless Internet.

To better use the main cabin space, Gulfstream designers rejected the usual circular fuselage cross-section in favor of an oval which uses a flatter lower portion.

The fuselage and wing are constructed mostly of metal while composite materials are used for the empennage, winglets, rear pressure bulkhead, engine cowlings, cabin floor structure and many fairings.

[62] The G650 became airborne briefly at a high angle of attack before its right wingtip hit the runway; then it slid on the ground, struck a concrete berm, and caught fire.
