The Gulfstream IV / IV-SP in-service business-jet fleet has surpassed three million flight hours. In service for 20 years, the GIV/GIV-SP remains the best-selling large-cabin, long-range business jet in its class with 535 aircraft of that family sold.
“The GIV significantly raised the bar in terms of what customers expected of their business jets,” said Joseph T. Lombardo, president, Gulfstream. “Today, these jets continue to serve their owners and operators well.”
At 99.92 percent dispatch reliability, the GIV continues to achieve one of the highest reliability ratings in the industry. For nearly two decades, the GIV, and later the GIV-SP, was the long-range aircraft of choice for business-jet aircraft customers, including heads of state, private individuals and air charter companies around the world. Gulfstream modeled two of its current in-production business-jet aircraft – the long-range G450 and the mid-range G350 – after the GIV/GIV-SP design.
The GIV was certified by the Federal Aviation Administration on April 22, 1987, and entered service on June 8, 1987. Gulfstream introduced the “special performance” GIV-SP in September 1992. The enhanced aircraft featured an updated landing package and increased takeoff and landing weight that allowed for heavier payloads and more flexibility in outfitting. The GIV/GIV-SP aircraft was manufactured for 16 years, with the last GIV entering service on September 13, 2003.
