N450BT

The airframe bearing tail number N450BT is a 2006-built Gulfstream GIV-X (G450), serial number 4065, manufactured by Gulfstream Aerospace. The aircraft is recorded as owned by TW AVIATION LLC with a listed location in Jupiter, FL, US, and is registered in the United States. The registry entry for this specific airframe notes a seating configuration of 22 seats, which contrasts with the more common executive layouts; this registry detail is a notable administrative record for the airframe. No additional public valuation or condition history is published in the supplied data.

This specific GIV-X is described with a registry-listed seating capacity of 22, although common executive cabin fits for the type typically range from 12–16 in a comfortable business configuration; registry notes indicate that the airframe can also support forward/aft galley and forward/aft lavatory options. The airframe is commonly outfitted with Honeywell Primus Epic / PlaneView avionics in this model family, a system widely used for advanced flight management and situational awareness. Operationally, a G450 with a 4,350 nm range and high cruise speed of 459 kts is capable of transcontinental and many intercontinental missions, making it suitable for owner-operator or charter roles based out of Jupiter, FL. Maintenance considerations for this airframe align with twin-engine long-range business jets, including engine-specific support for the Rolls-Royce Tay series.

The Gulfstream GIV-X (G450) occupies a long-range large-cabin business jet niche, offering high cruise speed and a 45,000 ft service ceiling that support efficient, high-altitude routing. Competing models in the segment include offerings from Bombardier and Dassault that target similar mission profiles and cabin sizes. Buyer and charter demand for this family typically emphasizes range, cabin flexibility, and avionics capability; the registry’s atypical 22-seat listing for this airframe may affect typical resale comparables and operator fitment decisions during remarketing or refit. Maintenance and resale considerations for the model generally reflect lifecycle support needs for Rolls-Royce Tay engines and avionics commonality with Honeywell Primus Epic installations.
