Model & Market Context
This entry covers Gulfstream airframe N251HR, a Gulfstream G450 (GIV-X) built in 2005 with manufacturer serial number 4027. The aircraft is registered in the US and is listed as owned by the corporation JOHNSON BREEDERS INC, located in Rose Hill, NC, US; currently registered to that corporate owner. Public registry filings or notable transfers are not published for this specific airframe in the supplied data. The airframe is valued at $12,298,000, reflecting market condition and outfitting typical of late-production G450s.
The cabin for this particular G450 is described as a typical executive fit with a 12–16 place layout as standard, with forward or aft galley options and a maximum certified seating capacity of 19–22 depending on specific outfitting; this airframe is equipped to accommodate up to 22 seats when configured to the maximum certification. Avionics are fitted in the common G450 arrangement, typically Honeywell Primus Epic / PlaneView, supporting advanced flight management, integrated displays and required business-jet navigation capabilities. Operational profiles for this airframe would include long-range corporate missions up to 4,350 nm, transcontinental and intercontinental legs at an economical cruise around 459 kts, operating from the owner/operator base in Rose Hill, NC or regional business hubs. Maintenance considerations align with mid-2000s G450s powered by Rolls-Royce Tay engines, emphasizing scheduled engine and airframe checks consistent with corporate charter or private-use cycles.
The Gulfstream G450 (GIV-X) occupies a performance niche as a large-cabin, long-range business jet capable of transoceanic flights without refueling for many city-pair routes, competing with types such as the Bombardier Challenger 605/650 family and the Dassault Falcon 2000/900 series. Demand in the pre-owned market is driven by range, cabin size, and avionics fit; the Honeywell Primus Epic / PlaneView suite and Rolls-Royce Tay engines are factors that influence maintenance scheduling and resale pricing. For this airframe, the listed valuation of $12,298,000 reflects age, equipment, and potential interior variation; buyers and operators typically weigh refurbishment costs, engine life, and avionics upgrades when assessing fleet additions or replacement.
