Representative imageUltra-long-range flagship
The G650ER held the title of the world's longest-range business jet for most of a decade: 7,500 NM at Mach 0.85, or Mach 0.925 when time matters more than fuel. The cabin is the widest Gulfstream had built, with panoramic windows and a cabin altitude low enough to make fifteen-hour sectors civilised.
It remains the benchmark the newest flagships are measured against, and record city pairs — Singapore–Tucson among them — were set on the type.
The aircraft
Gulfstream announced the G650 in March 2008 as its first genuinely clean-sheet design in decades — a wider, faster answer to Bombardier's Global family rather than another evolution of the GV line. The prototype flew on 25 November 2009, FAA certification came in September 2012, and deliveries began that December. The programme set out to hold two titles at once — longest range and highest cruise speed in business aviation — and for most of a decade it held both.
The ER followed in 2014: additional fuel capacity and higher weights stretching range from 7,000 to 7,500 NM, offered both on new aircraft and as a retrofit to existing G650s. That same year the G650 programme won the Collier Trophy, the award's citation pointing at exactly what buyers experience — performance, cabin comfort and safety advanced together rather than traded against each other.
Production wound down as the clean-sheet G700 entered service in 2024, and the final G650-series aircraft was completed in February 2025, closing the line at roughly 590 to 600 airframes across both versions with the G800 positioned as its successor. The end of production has, if anything, sharpened the type's standing: a settled, fully supported fleet of known quantity, no longer competing against new-build examples of itself.
Key figures
Standard published figures for a typically equipped Gulfstream G650ER. Individual airframes vary with configuration and modification — the specification on a listing is what governs.
We do not hold a Gulfstream G650ER on the books this week, but we place the type regularly. Tell us the specification, hours and budget, and we will come back with airframes that are genuinely available.

The broker’s view
The pre-owned G650/G650ER market is thin, international and fast-moving; the best airframes trade quietly between brokers before a listing ever appears. Many G650s have been converted to ER specification — verify the paperwork, since the modification is a fuel-capacity and weights change, not a badge.
If your missions genuinely run past 6,500 NM, almost nothing else pre-owned competes.
The family
The 2012 original with 7,000 NM range. Most have since been converted to ER specification — the change is fuel capacity and certified weights, so it must appear in the aircraft records, not just the sales listing.
The definitive version from 2014: 7,500 NM at Mach 0.85. Factory-built ERs and properly documented conversions trade at effectively the same level; an unconverted G650 prices below both.
The stretched successor, in service from 2024 with a five-zone cabin. It sits well above the G650ER on price; its arrival is what brought pre-owned G650ER values into reach for more buyers.
The G650 line's formal replacement — G700 technology on a shorter fuselage chasing maximum range. Context for where Gulfstream is heading, not yet a factor in the pre-owned market.
Common questions
Published range is 7,500 NM at Mach 0.85 — about sixteen hours, enough for Johannesburg–Los Angeles or Sydney–London-class sectors with reserves.
The ER carries roughly 4,000 lb more fuel at a higher maximum takeoff weight, stretching range from 7,000 to 7,500 NM. Most G650s can be converted; the aircraft records must show it.
Maximum operating speed is Mach 0.925 — among the fastest civil aircraft flying — with normal long-range cruise at Mach 0.85.
It is a flagship, and runs like one — crew, hangarage, insurance and reserves all price at the top of the pre-owned market. Set against that, the BR725s have an excellent service record, and the fleet's support network is mature worldwide. Programme-covered engines are effectively expected at this level.
The 7500 offers a longer, four-zone cabin and slightly more range; the G650ER counters with a deeper pre-owned pool, longer support history and lower capital cost. Both are superb. The honest deciding factors are cabin priorities, budget and which specific airframes are actually available.
The type's record is strong — values held unusually well through its production life, and a fixed fleet with continuing demand from buyers priced out of the G700 supports residuals. No aircraft is immune to cycles, but the G650ER's floor has repeatedly proven firmer than the class norm.
Buying or selling, the conversation costs nothing. Tell us the mission and the budget and we will tell you honestly whether the G650ER — or something else — is the right airframe for it.
