Gulfstream G450 Specifications
Performance
With a maximum range of approximately 4,350 nautical miles, a high-speed cruise capability near 500 knots, and a 45,000 ft service ceiling, the G450 is built for transcontinental, transatlantic, and high-utilization corporate missions. It remains especially attractive in the pre-owned market because it delivers large-cabin Gulfstream comfort without the acquisition cost of newer long-range models.
Powerplant
The G450 is powered by two Rolls-Royce Tay 611-8C turbofan engines, each producing 13,850 pounds of thrust. This engine installation gave the aircraft improved reliability, FADEC control, and performance refinements compared with earlier Gulfstream IV variants, helping the G450 earn a reputation as a dependable workhorse for private and corporate flight departments.
Operating Weights
Operating weights dictate the structural limits and mission profile of the aircraft. With an MTOW of 74,600 lbs, the Gulfstream G450 offers a high payload-to-range ratio.
