Mission Profile
About the Gulfstream G150
The Gulfstream G150 was produced by Gulfstream Aerospace (manufactured by Israel Aerospace Industries). It is a wide-cabin evolution of the G100/Astra SPX, noted for its speed (Mach 0.85 max) and ability to fly coast-to-coast in the US. The G150 features a wider fuselage than its predecessor, offering improved passenger comfort. It is powered by two Honeywell TFE731-40AR engines and uses Rockwell Collins Pro Line 21 avionics. Production ran from 2005 to 2017.
Key Features for GA Buyers
- Performance Leader: The G150 was marketed as the fastest mid-size business jet, capable of reaching Mach 0.85 and cruising comfortably at Mach 0.80.
- Transcontinental Range: With a range of nearly 3,000 nm, it can easily fly coast-to-coast in the US (e.g., New York to Los Angeles) or connect London to Moscow non-stop.
- Cabin Comfort: It features a wider, oval-shaped fuselage compared to its predecessor (the G100), offering significantly more seated headroom and shoulder room (seating 6-8 passengers comfortably).
- Avionics: Equipped with the Rockwell Collins Pro Line 21 avionics suite, which is highly regarded for its reliability and situational awareness features.
Trade-offs
- Out of Production: Production ended in 2017 (superseded by the G280), which may factor into long-term depreciation and support considerations compared to current production models.
- Runway Requirements: While decent for its class, its takeoff distance (5,000 ft at MTOW) requires longer runways than some lighter jet competitors, limiting access to smaller general aviation airfields.
- Cabin Height: While wider than the G100, the cabin height (5 ft 9 in) is not fully “stand-up” for taller passengers compared to super-midsize jets.
