Gulfstream G280 vs Gulfstream G400 vs Gulfstream G500 vs Gulfstream G600 vs Gulfstream G650er

The Gulfstream G280 is a super-midsize business jet, best suited for regional and transcontinental missions, with roughly 3,600 nautical miles of range and typically seating about 8–10 passengers. The Gulfstream G400 and G500 step into the large-cabin category: the G400 targets long-range missions at about 4,200 nautical miles with around 10–12 passengers in typical layouts, while the G500 offers a larger-cabin, longer-legged option at roughly 5,300 nautical miles, commonly arranged for about 10–14 passengers. The Gulfstream G600 sits above the G500 as a large-cabin, long-range jet, reaching about 6,600 nautical miles and usually configured for roughly 12–16 passengers. At the top of this set, the Gulfstream G650ER is an ultra-long-range, ultra-large-cabin aircraft, designed for true global missions at about 7,500 nautical miles, with typical passenger configurations around 14–18 depending on cabin layout. Overall, capability and cabin volume scale steadily from the G280 through the G650ER, with the biggest jump in global reach at the G600 and especially the G650ER.
