Gulfstream G450: Complete Specs, Performance, and Buyer's Guide (2026)
The Gulfstream G450 (designation GIV-X, in production from 2004 to 2018) is the direct successor to the Gulfstream G400/GIV-SP series and the platform that established Gulfstream's modernized large-cabin standard with the PlaneView cockpit, upgraded Tay engines with FADEC, and G550 nose section design heritage. The G450 demonstrated its speed in 2005 by setting a city-pair record flying Washington DC to Luton, England in 6 hours 12 minutes at Mach 0.85 average. Work began on the G450 in 2001. Flight-testing of the Gulfstream G450 started in April 2003 and FAA certification was completed in August 2004. Production began later that year. The G450 was designed using the G400 airframe with the G550 nose section grafted on - the fuselage is 12 inches longer than the original GIV, with the cabin entry door moved 3 feet to the right creating a cockpit that is 30% larger. Per Wikipedia / FlyCraft: "The Gulfstream G450 is a direct descendent of the Gulfstream G400/GIV-SP series. It comes with upgraded engines (Rolls-Royce Tay 611-8C) with FADEC, and redesigned thrust reverser, nacelle, and pylon that, coupled with aerodynamic improvements, increase range and payload." Powered by two Rolls-Royce Tay Mk 611-8C turbofan engines (each producing 13,850 lbf of thrust with FADEC, 12,000-hour TBO per some sources / 8,000-hour standard), the G450 delivers Mach 0.88 max speed (586 knots), Mach 0.85 cruise (476-533 knots), 4,100-4,350 nm range NBAA IFR (4,328 nm per Altivation NBAA 4 pax, 4,425 nm ferry range), 45,000 ft service ceiling, 3,760-3,850 ft/min climb rate, 712 ft/min single-engine climb. Climb to 41,000 ft in 23 minutes. Cabin: 45.1 ft length, 7.3 ft width, 6.2 ft height, 1,525 cu ft volume, 169 cu ft internal baggage. 9.5 psi cabin pressurization (sea-level cabin to 22,000 ft). 14-16 passengers typical (up to 18 high-density), sleeps 6. Three distinct cabin zones. Mix of single + double leather seats + four-person divan + large enclosed aft lavatory + well-appointed forward galley. PlaneView cockpit (Honeywell Primus Epic with Honeywell SPZ-8400 six-tube EFIS - 14-inch landscape LCD screens). Fly-by-wire flight controls. Enhanced Vision System standard. Head-Up Display standard. 4,015-4,300 gal fuel capacity. 465 GPH fuel burn. MTOW 74,600 lb (+1,400 lb vs G400). 5,450-5,770 ft balanced field length. 3,260-3,373 ft landing distance. Aircraft: 89 ft 3 in - 89 ft 4 in length, 77 ft 9-10 in wingspan, 25 ft 2 in tail height. Two Rolls-Royce Tay engines easily meet FAR Part 36 Phase III noise (79.1 EPNdB takeoff) and SFAR Part 27 emissions. 800+ hours wind tunnel testing. Total production: 360-365 G450s delivered worldwide. Production ended 2018 (transition to G500). New price at manufacture: $39-43M. Pre-owned market (per Guardian Jet 2024 data): $8.35M-$19.995M ask range (2005-2017 model years). Hourly charter rate per FlyCraft: $7,500. Per Air Charter Advisors: $3,695-$3,975/hr operating cost. The G450 became Gulfstream's most successful transitional large-cabin platform.
For operators wanting Gulfstream's modernized GIV/GIV-SP/G400 successor with the iconic G550 nose section design heritage, two upgraded Rolls-Royce Tay Mk 611-8C engines with FADEC (13,850 lbf each), PlaneView cockpit with industry-first standard Enhanced Vision System, 4,100-4,350 nm transcontinental and transatlantic range, fly-by-wire flight controls, 45,000 ft service ceiling, 1,525 cu ft three-zone cabin, premium 365-aircraft Gulfstream heritage, and $8.35M-$30M pre-owned market accessibility, the G450 represents Gulfstream's most successful modern legacy large-cabin platform.

History as Gulfstream's Most Successful Heritage Large-Cabin
The G450 represents Gulfstream's strategic decision to modernize the G400/GIV-SP platform with PlaneView avionics, FADEC engines, and the G550 nose section design.
Platform timeline:
- 1987: G-IV enters service (Tay 611-8 engines, glass cockpit, 4,091 nm)
- 1993: GIV-SP introduced (improved variant)
- 2002: G400 designation introduced (rebranded GIV-SP)
- 2001: G450 program begins
- April 2003: G450 flight testing starts
- August 2004: FAA certification
- Late 2004: Production starts
- 2005: First delivery; G450 sets DC-Luton city pair record
- 2018: Production ends (transition to G500)
- 365 G450s produced over 14 years
Per Aerocorner: "The G450 first flew in 2003 and entered service in 2004. Although derived from the GIV family, it incorporated a redesigned flight deck and aerodynamic refinements. Gulfstream positioned the aircraft as a dependable intercontinental platform capable of linking major business centers nonstop... The model represents one of Gulfstream's most successful transitional large-cabin jets."
