The Gulfstream IV is a long-range, large-cabin business jet developed by Gulfstream Aerospace, a division of General Dynamics. It first flew in 1985 and entered service in 1987, representing a significant advancement over its predecessor, the Gulfstream III, with improved range, fuel efficiency, and passenger comfort. Powered by two Rolls-Royce Tay turbofan engines, the GIV introduced a new supercritical wing design and advanced avionics, giving it the ability to fly transatlantic routes nonstop. The aircraft typically seats 12 to 19 passengers in a spacious cabin and can cruise at high subsonic speeds. The Gulfstream IV spawned several variants, including the G400 and the stretched G450, extending the platform's production life well into the 2000s. It has been widely used by corporations, governments, and charter operators around the world.
