Model & Market Context
This entry covers airframe N455KH, a Gulfstream G450 (GIV-X) built by Gulfstream Aerospace in 2008 with manufacturer serial number 4120. The airframe is registered in the US and is owned by REGIAN SERVICES LLC, a corporation based in Encino, CA, US; the current record reflects this corporate ownership and associated registry listing. The aircraft carries a market valuation of $11,495,000, reflecting its configuration and equipment, and is categorized as a fixed-wing multi-engine aircraft. Ownership has been held by REGIAN SERVICES LLC under U.S. registration since the noted registry action.
The cabin of N455KH is arranged in a 14-passenger layout with a forward four-place club; a mid-cabin four-place couch opposite two club seats; and an aft four-place conference group opposite a credenza, complemented by an aft galley. Avionics fit consists of Honeywell Primus Epic / PlaneView (enhanced navigation package), supporting enhanced navigation and systems integration for long-range business missions. Typical operational use for this airframe is consistent with long-range corporate transport enabled by its 4,350 nm range and 459 kts cruise speed; the Rolls-Royce Tay propulsion and avionics suite support transcontinental or extended point-to-point missions. Based at the owner’s location in Encino, CA, US, maintenance and operational considerations reflect the aircraft’s high-performance engines, complex avionics, and executive interior servicing needs.
As a member of the GIV-X/G450 production run, N455KH embodies the series’ blend of transcontinental range (4,350 nm), high cruise speed (459 kts), and a high-altitude ceiling (45,000 ft). The twin Rolls-Royce Tay Mk 611-8C engines provide the rated thrust that underpins the aircraft’s mission capability and operating performance. Buyer and operator considerations for this specific airframe include the value point of $11,495,000, the 14-place executive interior, and the installed Honeywell Primus Epic / PlaneView (enhanced navigation package), all factors that influence maintenance planning, aftermarket support, and resale positioning.
