The Gulfstream G450 entered production in October 2004. Twelve years later, its reliability, performance, and value continue to impress those in the aviation industry, and it remains a leader in its class. Here is a breakdown of the costs you should expect to incur, if you choose to own and operate a Gulfstream G450.


The G450 replaced the G400 in the Gulfstream line up. The G400 had grown out of the Gulfstream IV (GIV), which first entered service in 1987 and set several world records in its class.

Purchase Prices

A new Gulfstream G450 will currently cost between $38m to $43m. A pre-owned model will typically cost anywhere in the $14m to $35m range. A model built between 2006 and 2009 can be found for approximately $15m, while a newer model, from 2011 or thereabouts is typically in the $20m to $25m range. Prices of pre-owned aircraft will vary according to age, use, maintenance, records, and the level of upkeep.


The main cabin is 45ft 1 in (13.74m) in length, or 40ft 4in (12.29m) excluding baggage space, with a height of 6ft 2in (1.88m). It can carry up to 19 passengers and can sleep up to 6, depending on the internal configuration. The cabin is spacious enough for 3 living areas, 2 bathrooms, and a full galley.

A satellite phone, wireless local network, and multifunction printer are all standard, as is the 7-channel Honeywell satellite communications system. Advanced sound suppression reduces cabin noise by an additional 18%, compared to the aircraft’s predecessors, while the specially-designed oval windows double the amount of natural light in the cabin (as compared to comparable aircraft in its class). The designers of the Gulfstream G450 have also optimized fresh air circulation and cabin pressure in a way that reduces in-flight fatigue, thereby ensuring that you will reach your destination feeling refreshed and productive.

Gulfstream G450 Interior


The Gulfstream G450 operates with two Rolls-Royce Tay Mk 611-8C engines, each capable of producing 13,850 lb of thrust. The maximum range, based upon 8 passengers, 3 crew, IFR reserves and mach 0.80, is 4,350nm (8,056km). With 14 passengers and accompanying luggage, the range is 3,700nm (6,852km), or the equivalent of flying from Singapore to Dubai. The baggage compartment provides 130 cu ft of space. Takeoff distance is 5,600 ft (SL, ISA, MTOW).


The cockpit uses the Gulfstream PlaneView avionics system, which is based on Honeywells Primus Epic integrated avionics system. The cockpit is equipped with some of the most advanced current technology, including 4 display units, an Enhanced Vision System, and a Head-Up Display. A Synthetic Vision-Primary Flight Display is available as an optional extra.
