The Gulfstream G550 is a business jet aircraft produced by General Dynamics' Gulfstream Aerospace unit in Savannah, Georgia, US. The certification designation is GV-SP. There were 450 Gulfstream G550s in active service as of January 2016. A version with reduced fuel capacity was marketed as the G500.

Development
The G550 (GV-SP) with improved engines received its FAA type certificate on August 14, 2003.
Compared to the Gulfstream V, drag reduction details boost range by 250 nmi (460 km) and increase fuel efficiency. MTOW is increased by 500 lb and Takeoff performance is enhanced. A seventh pair of windows is added and the entry door is moved 2 ft. forward to increase usable cabin length. The PlaneView flight deck features cursor control devices, Honeywell Primus Epic avionics, standard head-up guidance system by Rockwell Collins and enhanced vision system by Elbit, improving situational awareness in reduced visibility conditions.
Initial long-range cruise altitude is FL 400-410, first hour fuel burn is 4,500-5,000 lb decreasing to 3,000 lb for the second hour and 2,400 lb for the last hour. Flight hourly budget is $700-950 for engine reserves, $250 for parts and 2.5 maintenance hours. It competes against the Bombardier Global 6000, which has higher direct operating costs and less range but a more spacious cross section, and the Dassault Falcon 7X with fly-by-wire flight controls, better fuel efficiency and a wider but shorter cabin.
The 500th Gulfstream G550 aircraft has been delivered in May 2015. As it is replaced by the $54.5 million Gulfstream G600 with a lower 6200 nmi range but with a better cabin and cockpit, faster long range cruise and lower fuel burn, it could leave production in 2019. Deliveries went from 50 aircraft in 2011 to 19 in 2016 and with 40 units for sale in a fleet of 540, its valuation are falling : a 10-year-old G550 valued $28 million a year before is worth $18-$20 million in January 2017, while a two-year-old went from $40 to $35 million. In May 2017, early 2003 G550s are valued $14 million against more than $45 million new, flying an average of 425 h per year.

Variants
- GV-SP
- The same as the Gulfstream V or GV with a new flightdeck display system, airframe aerodynamic and engine improvements, main entry door moved forward, also marketed as the G-550.
- G500
- The Gulfstream G500 has a reduced fuel capacity. Introduced in 2004 as a shorter 5,800 nautical miles (10,700 km) range version, it has the same exterior appearance, as well as the PlaneView cockpit, but Visual Guidance System (HUD) and Enhanced Vision System (EVS) are options.
- G550
- Marketing name for the GV-SP.
- C-37B
- U.S. military designation for the G550 in a VIP passenger configuration.
- EC-37B
- U.S. military designation for proposed G550 version in an Electronic Warfare configuration to replace USAF's existing EC-130H Compass Call aircraft.
- NP-37B
- U.S. military designation for proposed G550 with the "Conformal AEW" body shape for use as range telemetry aircraft for U.S. Navy.
- G550 Airborne Early Warning
- Israel has acquired a number of G550s, fitted with the IAI EL/W-2085 sensor package (a newer derivative of the Phalcon system) for Airborne Early Warning (AEW) use and named the aircraft Eitam. This aircraft is heavily modified for the AEW role by Gulfstream's partner, Israel Aerospace Industries (IAI), and is also called CAEW (Conformal Airborne Early Warning) by Gulfstream Special Missions Department. Israel has also acquired a number of G550s dubbed SEMA (Special Electronic Missions Aircraft) with systems integration also carried out by IAI. Italy has acquired 2 G550 CAEW as part of a counter-deal to Israel's $1 billion order for 30 Alenia Aermacchi M-346 advanced jet trainers. Singapore ordered four similar G550 CAEW aircraft equipped with the EL/W-2085 sensor package from Gulfstream and IAI.
- Air-to-air refueling variant: Israel Aerospace Industries has studied adapting the G550 for air-to-air refueling use.
Operators
Civil operators
The aircraft is operated by private individuals, companies and executive charter operators. A number of companies also use the aircraft as part of fractional ownership programs.
Government and military operators
- Australia
- In late 2015 the RAAF ordered two Gulfstream G550 aircraft to be delivered by 30 November 2017. The aircraft will be used for SIGINT and ELINT intelligence gathering. It is reported that the aircraft will possibly form the replacement for the electronic intelligence-gathering role performed by two of the RAAF's AP-3 Orions. In June 2017, the sale was approved and the United States confirmed that Australia was interested in purchasing up to five airframes, to be delivered in two tranches from the early 2020s.
- Germany
- German Aerospace Center (DLR) - 1 G550 special mission aircraft. The aircraft is dubbed HALO (High Altitude and Long Range Research Aircraft). The aircraft's primary objective is to explore the atmosphere and its carbon cycle. Its unique configuration allows a flying altitude of more than 15 kilometers (49,500 feet), a range of more than 8,000 kilometers, and a load capacity of three tons.
- Israel
- Israeli Air Force - 2 Eitam CAEW (Conformal Airborne Early Warning) and 3 Shavit SEMA (Special Electronic Missions Aircraft) aircraft
- Italy
