G650 The Gulfstream G650 was formally launched as an internal company project in May 2005, and publicly unveiled on March 13, 2008. 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. 2012 The wing design was completed in 2006. A total of 1,400 hours of
wind tunnel testing was completed by 2008. A pressure-test fuselage was built and tested, including an ultimate-pressure test of . The G650 taxied under its own power for the first time on September 26, 2009. A public rollout ceremony was held on September 29, 2009. The G650 had its
maiden flight on November 25, 2009. Flight testing for the maximum operating speed of Mach 0.925 was announced as completed on May 4, 2010. 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. In April 2011, a G650 crashed shortly after liftoff. The cause was determined to be related to the speeds carried out for the single engine takeoff run. The G650 test aircraft were grounded until May 28, 2011, when the remaining test aircraft were allowed to return to flight testing. On September 7, 2012, the G650 received its
type certificate from the US
Federal Aviation Administration (FAA). Its first delivery was to an American customer,
Preston Henn, on December 27, 2012. The G650 had a nominal list price of $64.5 million in 2013, but there was a three-year waiting list. Some aircraft produced for delivery in 2013 sold for more than $70 million to buyers that wanted to take immediate delivery. After rising to $71-73 million in 2014, initial enthusiasm dissipated and the value of pre-owned G650s stabilized at $50 million after the competing
Bombardier Global 7500 was certified in 2018. 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. The still emerging requirements call for an aircraft with a 10 to 13 man crew and a belly-mounted radar long. 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. The G650 aircraft project was named the 2014 winner of the
Collier Trophy, for having "strengthened business aviation through significant technological advancements in aircraft performance, cabin comfort, and safety." In September 2018, Gulfstream was conducting testing at
London City Airport to certify the aircraft to perform
steep approaches. In 2023, its equipped price was $68.5M for the G650, and $70.5M for the G650ER. The 400th was delivered in December 2019, seven years after the type's introduction. The 500th was delivered by Gulfstream's
Appleton completions facility in September 2022. In February 2025, the final G650 was completed; it is being replaced by the G800.
G650ER 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 at Mach 0.85, due to its increase in fuel capacity. Gulfstream stated that in March a G650ER development aircraft had flown non-stop from Hong Kong to Teterboro, New Jersey in the United States, a distance of ; it had also flown non-stop from Los Angeles to Melbourne in Australia. 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. The G650ER attempted two world records from New York to Beijing to Savannah in February 2015. The same year, a G650ER set a new record for the longest non-stop flight by a purpose-built business jet, flying from Singapore to Las Vegas with four passengers and crew. The record was surpassed by a Bombardier Global 7500 in March 2019, before the G650ER retook the record in April 2019 by flying 8,379 nmi (15,518 km) from Singapore to Tucson. Production on the G650 ended in February 2025, with it being replaced by the G800.
G700 2023 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. It should fly at Mach 0.85 or at Mach 0.90. Its longer cabin can accommodate up to five areas and has 20 windows. It is powered by
Rolls-Royce Pearl 700 engines and has new winglets. Customer deliveries were originally planned to start in 2022. In July 2023, FAA approval was expected to be received in the autumn. The $75 million jet is a stretch of the G650. The aircraft completed its first flight on February 14, 2020. 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. The jet is long, about longer than the G650ER and about shorter than the competing
Bombardier Global 7500. Its main cabin is long, high and wide; longer, wider and slightly taller than the 7500's cabin. It should carry 19 seated passengers or sleep 10. It will have a
MTOW of and the 18,250 lbf (81.2 kN) turbofans should burn 2–3% less fuel than the G650's R-R
BR725s. The aircraft should need a runway at MTOW in ISA conditions at sea level and land in at a typical landing weight. It has the same wing with its 33° wingsweep but the more outboard canted winglets are wider. The
basic operating weight increases from and the
wet wing fuel capacity increases slightly by . The Pearl 700 turbofan is an improved version of the BR725, with one more low-pressure turbine stage, an
overall pressure ratio over 50:1, and a
bypass ratio higher than 6.5:1 for a 3–5% better
thrust specific fuel consumption. After flight tests, G700 bested its competitor's range and reached up to . The maximum operating speed of the G700 has increased from Mach 0.925 to Mach 0.935, ranking it as the fastest in the Gulfstream product line. In 2023, its equipped price was $79.9M. The FAA issued its certificate on 29 March 2024, and the first two deliveries, to US-based customers, took place on 23 April 2024. On April 23, 2024, Gulfstream began customer deliveries of its new G700 aircraft, less than a month after obtaining
Federal Aviation Administration (FAA) certification. The first two G700s have begun service. The G700 was nominated for the 2024 Collier Trophy, ultimately awarded to the
Parker Solar Probe. In 2026, the Gulfstream G700 received certification from India's Directorate General of Civil Aviation, while Transport Canada approved both the G700 and G800 models, allowing them to operate and be registered in those markets.
G800 On October 4, 2021, Gulfstream unveiled in Savannah the Gulfstream G800, with the G700 wing and Pearl 700 engines, offering 8,000 nmi (14,800 km) range, four living areas, and 16 windows, with deliveries planned to begin in 2023. Priced at $72.5 million, The G800 first flew on June 28, 2022 and FAA certification was expected in the first half of 2025. The G800 received FAA and EASA certification in April 2025, with the maximum range of 8,200 nmi (15,200 km) and maximum speed of Mach 0.935, increased from the original announcement. The first G800 was delivered in late August 2025. ==Design==
