Gulfstream G550

Updated: October 2026 – Two engines at the rear, a T-tail, a long, slim fuselage and a row of oval windows: on the GA apron that looks like “some Gulfstream.” If you count seven windows per side, you are very likely looking at a Gulfstream G550 – the long-range business jet that shaped the image of large private jets for almost two decades. But it is exciting for spotters for another reason, too: it serves several air forces as a special mission platform. Here you will learn how to identify the G550 reliably, how to tell it from the GV, G650 and competitors, and which military versions you should know.

What is the Gulfstream G550?

The G550 is a twinjet long-range business jet from Gulfstream Aerospace of Savannah in the US state of Georgia. Technically it is not a new design but the thoroughly revised Gulfstream GV. In the certification documents it is therefore called the GV-SP; it was sold as the G550. The US aviation authority FAA granted the type certificate on August 14, 2003, and service with the first customers began shortly after.

According to the manufacturer, the G550 flies up to 6,750 nautical miles, or a good 12,500 kilometers. That lets it fly routes such as Geneva–Singapore or Munich–Los Angeles without a stopover. Depending on layout, the cabin holds 14 to 19 passengers, but in everyday use most cabins are generously fitted with seating groups, a dining table, a galley and a rest area. It is flown by two pilots, often supplemented by cabin crew on long routes.

What changed compared with the GV? Gulfstream moved the entry door about 60 centimeters forward and thereby gained usable cabin length. Added to this was a seventh pair of windows. Smaller aerodynamic improvements brought about 250 nm of additional range. In the cockpit the PlaneView system arrived, with Honeywell Primus Epic avionics, a head-up display and an Enhanced Vision System from Elbit – an infrared camera that projects an image of the surroundings into the pilots’ field of view in poor visibility.

The G550 is powered by two Rolls-Royce BR710 engines with about 68 kilonewtons of thrust each. The BR700 family comes from the Rolls-Royce Deutschland plant in Dahlewitz south of Berlin. You can read more about the engine maker on the page for Rolls-Royce, and more about the aircraft manufacturer at Gulfstream Aerospace.

A success story with staying power

The G550 hit the market at the right time. In May 2015 Gulfstream already delivered the 500th aircraft. Competitors were mainly the Bombardier Global 6000 and the three-engine Dassault Falcon 7X. With the larger and more modern G650 it got strong competition from within its own company.

From 2019 the newly developed G600 took its place in the lineup. The last civil G550 went to its customer in June 2021; in total more than 600 aircraft left the halls in Savannah. Production ended shortly afterward. The existing fleet is large and keeps flying – as a spotter you will be encountering it for a long time.

A curiosity on the side: starting in 2004 Gulfstream offered a G550 with smaller tanks and about 5,800 nm of range as the G500. This early G500 hardly sold and has nothing to do with today’s Gulfstream G500 – that is a completely new design from the G600 and G700 family.

The three features that are enough to identify it

Large business jets look alike: rear engines, T-tail, white paint, often without a logo. With Gulfstream the horizontal oval windows give you a strong identifying mark. The art lies in telling the generations apart.

How type codes are structured and why several variants share the same code is explained in the article ICAO type codes explained. How to read a registration and assign it to a country is covered in Understanding aircraft registrations.

GV, G550, G650 or G600?

Gulfstream develops its models in generations that look strongly alike at first glance. The table helps you sort them out.

Feature	GV	G550	G650/G650ER	G600
ICAO type designator	GLF5	GLF5	GLF6	own code
Windows per side	6	7	8 (large)	large, new shape
Engine	Rolls-Royce BR710	Rolls-Royce BR710	Rolls-Royce BR725	Pratt & Whitney Canada PW800
Cockpit	classic	PlaneView	PlaneView II	Symmetry Flight Deck
Range (manufacturer)	–	6,750 nm	7,000 / 7,500 nm	–

The GV is the direct predecessor from the late 1990s. Outwardly it is extremely similar to the G550 – the missing seventh pair of windows and the door sitting slightly farther aft are the main differences. One generation older still is the G450, which is based on the GIV: it is shorter and flies with Rolls-Royce Tay engines.

The G650 is a true new design with a wider fuselage and a more strongly swept wing. The G600, finally, replaced the G550 in the lineup. It comes from a new family and carries different engines; in the cockpit it flies with sidesticks, and from the outside the larger panoramic windows help most. If you want to go deeper, the guide Telling business jet types apart covers the differences between Gulfstream, Global, Falcon, Citation and Challenger.

G550, Global 6000 or Falcon 7X?

During its active sales period the G550 had two main competitors, both designed for long range. You meet all three regularly on the same aprons in Europe. The finder narrows them down with three questions.

You rule out the Falcon 7X fastest: its third engine sits in the middle of the tail. Trickier is the Global 6000, which, like the G550, carries two rear engines and a T-tail. But it looks more stretched, and its windows are not as distinctly oval. Its predecessor, the Global Express, looks very similar.

The G550 as a special mission platform

Long range, a high service ceiling of 51,000 feet, lots of space and a robust aircraft with worldwide support – this mix made the G550 interesting for air forces. Its military offshoots are correspondingly versatile.

VIP transport (C-37B): In the US armed forces the G550 flies as the C-37B. It carries government members and senior officers around the world and hardly differs outwardly from the civil model – apart from the government paint scheme and the military serial. More on how to catch such aircraft during state visits is in the article Spotting government aircraft.

Early warning aircraft (CAEW): Israel Aerospace Industries converts the G550 into an early warning aircraft with the EL/W-2085 radar. Instead of a rotodome like on the Boeing E-3 Sentry, the antennas sit in conformal fairings attached directly to the fuselage: on the sides of the fuselage as well as in an enlarged nose and in the tail. Israel operates these aircraft under the name Eitam, Singapore operates four examples that have been fully operational since 2012, and Italy flies them as the E-550A. Once you have seen a G550 like this, with fat cheeks and a bulbous nose, you never forget the sight.

Electronic warfare (EA-37B Compass Call): The US Air Force is replacing its old EC-130H Compass Calls with a G550-based version. L3Harris and BAE Systems integrate the jamming electronics. The aircraft was originally called the EC-37B and was renamed the EA-37B in November 2023. The first aircraft for training operations went to Davis-Monthan Air Force Base in Arizona in August 2024.

Reconnaissance (MC-55A Peregrine): The Australian air force is acquiring a G550 version for electronic warfare and reconnaissance under the name MC-55A Peregrine; the first aircraft arrived in January 2026 at RAAF Base Edinburgh in South Australia. How US military serials are structured is explained in the article US military serials.

How to tell early warning and reconnaissance aircraft apart in general is explained in the guide Identifying AWACS and reconnaissance aircraft. A modern comparison with a large flat radar is the Boeing E-7 Wedgetail. You will find tips on tracking military flights in Tracking military aircraft online.

Where you will find the G550

Business jets do not fly fixed routes. The G550 turns up wherever owners, companies, charter customers or governments want to go – timed by business trips, trade fairs, summits and vacation periods. With more than 600 built, it is among the most common large long-range bizjets of all. Because many aircraft are now 15 to 20 years old, they change owners more often – and thus often registration and home country. For collectors that is appealing: the same serial number can turn up under several registrations – more on this in the article Collecting registrations.

Switzerland: At Geneva Airport, international organizations, banks and private travelers provide a lot of business jet traffic all year. At Zurich Airport, the rush peaks around the World Economic Forum in Davos in January.

Germany: In Munich, trade fairs and the Munich Security Conference in February bring additional business and government traffic. Frankfurt, Düsseldorf, Hamburg and Berlin also regularly see Gulfstreams.

Austria: In Vienna, keep an eye on international conferences; in Salzburg, on the festival season and ski season.

Location	Chance of success	Why
Geneva	high	Strong business jet traffic year-round
Zurich (January, WEF)	high	Many long-range jets in a short time
Munich	medium	Trade fairs, security conference, business traffic
Vienna	medium	Conferences and international organizations
Salzburg (season)	medium	Festival and winter sports

The matching vantage points: in Geneva the observation deck, in Zurich the Butzenbüel, in Munich the visitors’ hill (Besucherhügel), in Salzburg the observation deck and in Vienna the observation deck at Vienna Airport. General tips for catching bizjets are provided by the guide Spotting business jets, and location-specific advice is in the guides Plane spotting in Geneva and Plane spotting in Zurich. How to find a specific aircraft is explained in Tracking an aircraft by registration.

Photo tips specifically for the G550

At just under 30 meters long, the G550 is smaller than any airliner but big enough for impressive pictures. Its slim fuselage looks especially elegant in profile.

You calculate in advance when the light suits your spot – the guide Planning sun position for your photo spot shows how. Whether your vantage point is legally unproblematic is covered in the article Is plane spotting allowed?.

Common mix-ups and how to rule them out

Conclusion

The G550 is the classic among the large Gulfstreams: widespread, reliable and, thanks to the seven oval windows, easy to identify if you look closely. Its real appeal for collectors, though, lies in its variety – from corporate jet to government aircraft to an early warning aircraft with conformal radar. Production has ended, but the fleet will stay with you for many years.
