RADAR ESTIMATE

What N999TR is worth, and where it’s heading.

Radar's value model doesn't cover the Gulfstream IV-SP on its own yet, so this borrows the Gulfstream G450 curve, scales it to N999TR's listing-based estimate and widens the range to match. An estimate, not an appraisal.

RESEARCH NOTES

About N999TR

Compiled with AI assistance from the public sources listed below, November 2025. Not checked against the aircraft's logbooks.

Overview

The aircraft is a Gulfstream IV-SP built in 1994, registered in the United States as N999TR and bearing manufacturer serial number 1248. It is operated and owned by N999TR LLC, an LLC based in Lewes, DE, US, and appears on U.S. civil registers under that ownership. Routine registry entries and platform summaries report avionics and capability listings, but no separate publicized change-of-ownership events beyond the current LLC ownership are provided.

Operations & Cabin

The cabin is described as a typical executive stand-up layout designed to accommodate 14-19 passengers in normal executive configurations, with an approximate cabin length of 45.1 ft; the exact onboard layout for this airframe is not published. Avionics summaries for this specific registration report a Honeywell SPZ-8000 fit and note capability for FANS/CPDLC and WAAS/LPV operations, indicating the airframe is equipped for modern airspace and navigation procedures. With a long-range capability of 4,091 nm and cruise speed of 459 kts, the aircraft is operated for long cross-country or transoceanic-capable missions from its base in Lewes, DE, under the single LLC owner. Maintenance considerations for this airframe focus on aging-aircraft systems and the twin Rolls-Royce Tay 611-8 engines typical of G-IV airframes; specific on-board amenities or unique modifications for N999TR are not published.

Model & Market Context

The Gulfstream IV-SP airframe represented by N999TR fills a long-range, large-cabin business jet niche with a high operational ceiling (45,000 ft) and transcontinental range (4,091 nm) relative to its era. The airframe’s seating for 22 and executive cabin length (~45.1 ft) align it with operators prioritizing capacity and comfort on extended missions.
