Gulfstream IV

Listing-based estimates for the 22 IVs on Radar run from about $2M to $5.8M, with a middle estimate of $4.5M. They are rough estimates from public listings and market reports, not appraisals.

What moves the price of any one IV: total time and engine time, engine program enrollment, damage history, avionics and equipment, and complete logbooks. Build year sets the baseline; a IV with high hours, an engine near overhaul or gaps in its records sells below it, and one with low time, recent inspections and full records above it.

Radar does not list aircraft for sale. It tracks all 214 US-registered IVs by tail number, each with its registration record and a value estimate, so you can check a listing against the value of its build year and look up the aircraft's own history before you call.

214 IVs are on the US civil aircraft register (FAA file of October 2026), built 1991 to 2002. Aircraft registered in other countries are not counted. Radar has a page for each US registration.

As published for the Gulfstream IV-SP: up to 19 passengers, a range of 4,220 nm (4,856 statute miles), a high-speed cruise of 500 ktas (575 mph), a cabin 6 ft 1 in high, 7 ft 4 in wide and 2 × Rolls-Royce Tay 611-8 engines. A given aircraft varies with its completion, weight and modifications.

The IV's published range is 4,220 nautical miles (4,856 statute miles), with m0.80, 8 passengers, 3 crew, NBAA IFR reserves (same figure on both the GIV and GIV-SP pages). Winds, payload, cruise speed and the reserves a flight carries change what a given trip can do.

Yes. New York to London is about 2,986 nm, inside the IV's published range of 4,220 nm, so the crossing can be flown nonstop.

Yes. Los Angeles to Honolulu is about 2,217 nm, well inside the IV's published range of 4,220 nm.

The IV cruises at up to 500 knots true airspeed (about 575 mph), as published for the Gulfstream IV-SP.

Up to 19 passengers, the most the type is published for (Gulfstream IV-SP). Many aircraft are completed with fewer, larger seats, so a given IV may seat fewer.

Of the 214 US-registered IVs, 208 (97%) are registered to companies, trusts and other entities and 6 to individuals. Radar names entity owners only; individuals are shown as privately registered. The most common states of registration are CA (39), DE (34), FL (26).

Radar covers the IV (built 1987 to 2004), the IV-SP (built 1991 to 2002) and the G400 (built 2004). They share this page because people search for them as one aircraft; each has its own section with its specs, value and tail numbers.
