Model & Market Context
This airframe, registered as N458FX, is a Gulfstream GIV-X (G450) built in 2011 with manufacturer serial number 4238. The aircraft is owned by FLEXJET LLC, an LLC based in Cleveland, OH, US, and is registered in the US; the registry lists a full passenger configuration of 22 seats. The platform is valued at approximately $25,000,000 and is equipped and certified as a fixed-wing multi-engine business jet. Ownership by FLEXJET LLC places this airframe within a fractional and charter operating environment typical of the operator’s network.
The cabin of N458FX follows a typical executive layout that is model-configurable; common outfitting for this model runs 12–16 pax, though the registry for this airframe lists 22 seats, indicating a maximum-certificated seating arrangement rather than a representative executive fit. Avionics are listed as Gulfstream PlaneView, supporting modern flight-deck functionality and common operational procedures used by Gulfstream-equipped fleets. Operational use for this specific airframe is consistent with fractional ownership and charter missions—medium- to long-range executive transport—leveraging its 4,350 nm range and cruise speed of 459 kts from a hub in Cleveland, OH. Maintenance and configuration choices are driven by operator standards and the GIV-X platform’s established support network.
The Gulfstream GIV-X (G450) occupies the large-cabin, long-range segment of the business-jet market, offering transcontinental and some intercontinental capability with a service ceiling of 45,000 ft. Competing models in the same niche include other large-cabin business jets offering similar ranges and cruise speeds; buyer and charter demand often favor proven avionics suites such as Gulfstream PlaneView and reliable powerplants like the Rolls-Royce Tay Mk 611-8C. Resale and maintenance considerations for this airframe reflect typical G450 economics: a robust secondary market for well-maintained examples and value influenced by configuration, total time, and operator maintenance standards.
