Gulfstream G IV (G4)

Large‑Cabin Intercontinental Jet

“4 000 + nautical miles of nonstop possibility—land rested, ready, and ahead of schedule.”

LEGENDARY PERFORMANCE, TIMELESS PRESTIGE

For more than three decades the Gulfstream G IV has been the gold standard for transcontinental business travel. Twin Rolls‑Royce Tay engines, a swept supercritical wing, and an aerodynamically clean fuselage let you cruise above weather and airline traffic at 45 000 ft while enjoying a whisper‑quiet, stand‑up cabin built for productivity—or pure relaxation. With Alta Aviation’s upgraded avionics and refreshed interiors, the G4 remains a flagship that outperforms many newer jets in its class.
