Model & Market Context
This airframe, registered as N450MB, is a 1996 Gulfstream G-IV SP built by Gulfstream Aerospace with serial number 1295. The aircraft is owned by Aircraft Fidelity Corporation Trustee, a corporation based in Dover, DE, US, and is registered in the US. The airframe’s build year, serial and trustee ownership define its documented provenance; ownership has been recorded under a corporate trust based in Dover, Delaware. Public registry entries and operator records indicate standard corporate custodianship and U.S. registration actions for this airframe.
The cabin of this Gulfstream G-IV SP is reported in a 13-place executive layout with a forward crew lavatory, a full aft galley and an aft passenger lavatory; the configuration is also reported to sleep 5–6. Seating and service arrangements reflect executive transport outfitting within the wider 22-seat certification envelope. The aircraft’s U.S. registration and trustee ownership situate its operational base administratively in Dover, DE, though specific operator flight logs or line operations are not published. Avionics fit and detailed operational equipment lists for this specific serial are not published in the supplied data.
The Gulfstream G-IV SP family occupies the long-range large-cabin executive transport niche, offering intercontinental capability consistent with the listed 4,220 nm range and a typical long-cruise speed near 459 kts and service ceiling of 45,000 ft. Powered by a pair of Rolls-Royce Tay 611-8 engines producing 13,850 lbf each, the model competes historically with other late-1990s long-range business jets in charter and corporate markets. For this specific airframe, considerations for buyers or operators would focus on provenance, maintenance history tied to serial 1295, and interior configuration (13-place executive, sleeping provision for 5–6) as principal value and mission-defining attributes.
