GULFSTREAM IV-SP

Proven Luxury and Long-Range Power

The Gulfstream IV-SP is a long-range business jet that offers outstanding performance, exceptional cabin comfort, and a reputation for reliability. As a refined version of the original GIV, the IV-SP includes upgrades in avionics, payload, and runway capability. As a result, it remains a highly respected choice for corporate travel and intercontinental missions.

Performance and Range

Powered by two Rolls-Royce Tay 611-8 engines, the Gulfstream IV-SP produces 13,850 pounds of thrust per side. Thanks to this power, the jet can cruise at Mach 0.88 and reach distances of up to 4,220 nautical miles. That range allows nonstop flights between cities such as New York and Paris or Dubai and Tokyo.

Moreover, the aircraft’s maximum ceiling of 45,000 feet ensures smoother flight by cruising above weather systems and commercial air traffic. In comparison to earlier Gulfstream models, the IV-SP offers improved takeoff performance—making it ideal for operations at shorter or high-elevation runways.

Cabin Design and Comfort

The Gulfstream IV-SP cabin features an executive layout for 13 to 14 passengers. It spans 45.1 feet in length, 6.1 feet in height, and 7.3 feet in width. Therefore, passengers enjoy more space for productivity and relaxation throughout their journey.

Additionally, the three-zone cabin can include:

– Club seating and divan lounges
– A full-service galley for hot and cold meal prep
– A private lavatory, forward or aft
– In-flight accessible baggage compartment
– Optional crew rest area for extended-range trips

Thanks to Gulfstream’s renowned craftsmanship, the cabin offers excellent insulation and large windows that enhance light and reduce fatigue.

Avionics and Flight Deck

Originally equipped with the Honeywell SPZ-8400 suite, many Gulfstream IV-SPs have been upgraded for modern operations. Newer systems may include:

– ADS-B Out, WAAS/LPV navigation, and GPS modernization
– Dual flight management systems
– High-definition EFIS displays and integrated weather radar
– TCAS II for traffic avoidance

As a result of these enhancements, the GIV-SP continues to meet current international standards and provides pilots with improved situational awareness.

Ownership and Market Value

The Gulfstream IV-SP represents strong value in today’s long-range jet market. As of 2025, prices typically range from $2.5 million to $5.5 million, depending on engine program status, avionics upgrades, and interior condition.

Furthermore, Gulfstream’s global service network provides dependable maintenance and parts availability. When compared to models like the Falcon 900EX or Challenger 604, the GIV-SP holds its own in terms of range, cabin volume, and total cost of ownership.
