Which Should You Buy: Gulfstream G450 or Gulfstream G550?

Bottom line: Choose the G450 for large-cabin capability at the lowest entry point — a proven Gulfstream with the range for most long-haul missions. Choose the G550 for genuine ultra-long-range reach — a globally supported, time-tested airframe that crosses oceans with ease. Choose the G650 for the flagship — greater speed, longer range and a larger, quieter cabin, at a clear premium. On safety all three are two-crew, large-cabin Gulfstreams with excellent records and twin-jet redundancy; the difference is range, speed and cabin, not safety. Value reach, global range, or the benchmark.

Frequently Asked Questions

What's the difference between the G450, G550 and G650?
They climb in range and capability — the G450 is the shortest-legged of the three, the G550 a true ultra-long-range jet, and the G650 the newer, faster flagship with the longest range and largest cabin.
Which has the longest range?
The G650 — it extended Gulfstream's range and speed beyond the G550, which is itself genuinely intercontinental. The G450 has the shortest range of the three.
Which is the better value?
The G450 carries the lowest price for large-cabin capability; the G550 offers proven global range for less than a G650, which commands a premium as the newest flagship.
Which is better, Gulfstream G450 or Gulfstream G550?
It depends on your mission and budget. The G450 cruises at 476 kts with 4,350 nm range. The G550 cruises at 488 kts with 6,750 nm range. Review the specs table above to find which fits your flying profile.
How do prices compare?
Gulfstream G450: from $9,950,000. Prices vary by year, hours, avionics, and condition. Always get a pre-buy inspection.
What's the difference between Gulfstream G450 and Gulfstream G550?
Seats: 16 vs 18. Cruise: 476 vs 488 kts. Range: 4350 vs 6750 nm.
Which is cheaper to operate per hour?
G450: about $3600/hr variable cost. G550: about $5500/hr variable cost. Variable cost includes fuel, reserves and overhaul accruals. Annual fixed costs (hangar, insurance, annual inspection) add to the total.
Which has more seats and useful load?
G450: 16 seats / 22,000 lb useful load. G550: 18 seats / 27,500 lb useful load. Useful load = max gross weight minus empty weight; it determines how much fuel plus payload you can carry.
How does maintenance compare — TBO and overhaul cost?
G450: 6,000-hour TBO, overhaul ~$700,000. G550: 7,000-hour TBO, overhaul ~$1,300,000. Reaching the time-between-overhaul (TBO) triggers a mandatory engine/airframe rebuild that affects resale value.
