Gulfstream G550

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. As of January 2016, there were 450 G550s in service.[4] The final G550 commercially available unit is to be delivered in 2021.[5] A version of the airplane with reduced fuel capacity was marketed as the G500.

This article is about the GV-SP based G500. For current G500, see Gulfstream G500/G600.

Development
G550 cabin

The G550 (GV-SP) with improved engines received its FAA type certificate on August 14, 2003.[6] In 2014, Gulfstream looked at a re-engine with the Rolls-Royce Pearl BR700 development announced in May 2018 for the new Global Express 5500 and 6500 variants but preferred the BR725-powered, 7,500 nmi G650.[7] The 500th Gulfstream G550 aircraft was delivered in May 2015.[8]

As it is replaced by the $54.5 million Gulfstream G600 with a lower 6,200 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.[9] In May 2017, early 2003 G550s are valued $14 million against more than $45 million new, flying an average of 425 h per year.[10] In December 2018, a 2012-2013 G550 is valued $28-31 million, and it costs $7,135 per hour for 400 hours a year.[11]

As it was replaced by the Gulfstream G600 by October 2019, the G550 was kept in limited production for long-term special missions applications and government orders.[12]

Design
G550 flight deck

Compared to the Gulfstream V, drag reduction details boost range by 250 nmi (460 km) and increase fuel efficiency. Maximum takeoff weight (MTOW) is increased by 500 lb (230 kg) and takeoff performance is enhanced. A seventh pair of windows is added and the entry door is moved 2 ft (0.61 m) 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.[10]

Initial long-range cruise altitude is FL 400-410, first hour fuel burn is 4,500–5,000 lb (2,000–2,300 kg) decreasing for the second hour to 3,000 and 2,400 lb (1,400 and 1,100 kg) 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.[10]

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.[6] 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 CAEW
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.[17] Israel has also acquired a number of G550s dubbed SEMA (Special Electronic Missions Aircraft) with systems integration also carried out by IAI.[18] 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.[19] Singapore ordered four similar G550 CAEW aircraft equipped with the EL/W-2085 sensor package from Gulfstream and IAI.[20]

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.[24] 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.[24][25] 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.[26][27] In March 2019, the Minister for Defence and Minister for Defence Industry in a joint statement announced the procurement of four modified Gulfstream G550 aircraft for use in electronic warfare missions. The aircraft, to be designated MC-55A Peregrine in Australian service, are to be modified in the U.S. and delivered to RAAF Base Edinburgh in a deal worth US$ 1.7 billion.[28]

gollark: I think systemd actually does roughly that, but with targets.
gollark: I mean, yes, I *could* just use a folder of "services" and a folder of "enabled services" and some symlinks, and that *would* probably work.
gollark: Oh, I have a fun idea, I can use SQLite3 for storing data like which services are enabled.
gollark: Obviously this will have to know when a process exits so it can restart it, but people want to be able to stop/start/restart a service.
gollark: I see. So for my thing I suppose I'll just have to have a thread waiting for each process (ugh, but what can you do) and then... hope that if I kill that, `wait` will handle it okay.
