The Gulfstream IV is a large-cabin, long-range business jet developed by Gulfstream Aerospace, a subsidiary of General Dynamics. It entered service in the late 1980s and represented a significant advancement over its predecessor, the Gulfstream III, featuring a redesigned supercritical wing and more fuel-efficient Rolls-Royce Tay turbofan engines. The aircraft is configured primarily for private and corporate transport, typically seating 14 to 19 passengers in a luxurious cabin environment. It is capable of transatlantic and intercontinental missions, making it a preferred choice for business executives, governments, and charter operators worldwide. The Gulfstream IV spawned several variants, most notably the G-IV-SP (Special Performance), which offered enhanced capabilities. The platform eventually evolved into the Gulfstream G450. While production has ended, many examples remain in active service globally.
