The Gulfstream G650ER: Why It Remains the Ultra-Long-Range Benchmark

A decade after launch, the G650ER still defines the segment

Introduction\n\nThe Gulfstream G650ER, certified in 2014, remains the aircraft against which every ultra-long-range design is judged. Even with the arrival of the Global 7500 and the forthcoming G700, the 650ER continues to dominate residual values and active utilisation.\n\n## Why it endures\n\nThree reasons explain the longevity: a clean wing optimised for high cruise, a cabin volume that hits the sweet spot for transcontinental missions, and a global support footprint that newer entrants are still building.
