Gulfstream-IV is a VIP transport aircraft with a seating capacity of 14-19 people. It has Max Speed of Mach 0.88 (505 knots, 581 mph,
935 km/h at altitude) and Range of 4,220 nmi (7,820 km; 4,860 mi).
The Gulfstream IV wing has a more swept outboard shock resulting in lower drag. Other benefits arising from this design are a lower root bending moment due to the more inboard center of pressure, a lower stall speed due to washout and a larger fuel volume due to increased chord. These aerodynamic improvements result in an increase in range of over 300 nautical miles.
