RADAR ESTIMATE
What N154G is worth, and where it’s heading.
Radar's value model doesn't cover the Gulfstream IV on its own yet, so this borrows the Gulfstream G450 curve, scales it to N154G's listing-based estimate and widens the range to match. An estimate, not an appraisal.

RESEARCH NOTES
About N154G
Compiled with AI assistance from the public sources listed below, November 2025. Not checked against the aircraft's logbooks.
Overview
The airframe bearing tail number N154G is a 1987-built Gulfstream G-IV with serial number 1044, delivered from Gulfstream Aerospace Corporation and currently owned by GLF4 1044 LLC, an LLC based in Fort Lauderdale, FL, US. Recorded ownership by GLF4 1044 LLC places the jet under an LLC operating base in Fort Lauderdale, FL, and registry listings note the airframe as a typical mature late-1980s G-IV example. Maintenance and valuation notes on listings emphasize its executive interior and avionics fit when assessing condition and market comparables.
Operations & Cabin
The cabin of this specific G-IV is reported as a 13-place executive layout featuring a forward 4-place club, a mid-cabin 4-place club, and an aft 3-place divan, with forward and aft lavatories and a full galley, supporting long-range executive missions and group charters within the aircraft’s transcontinental and intercontinental capability. Avionics listings describe a Honeywell PlaneDeck / SPZ-8000 IFCS installation with dual Honeywell NZ-2000 FMS units and a Collins communications suite, a fit indicating upgraded navigation and flight management capability relative to original production equipment. Typical operations would include owner/operator or charter flights out of its Fort Lauderdale home base on missions leveraging the G-IV’s ~4,200 nm range and 459-kt cruise speed; maintenance planning will reflect the airframe’s 1987 vintage and the Rolls-Royce TAY engine type.
Model & Market Context
The Gulfstream G-IV family occupies the large-cabin, long-range business jet niche, offering transcontinental or transoceanic capability for groups and corporate operations. Competing models span later large-cabin types with newer engines and avionics; within the used market, a 1987 G-IV such as N154G is assessed on interior condition, avionics upgrades, and engine program status, factors that strongly influence resale and charter demand. Maintenance and parts support remain well established for the G-IV platform, but prospective buyers evaluate the airframe against modernization costs to bring systems and cabin amenities in line with newer competitors.
