The Gulfstream G150 was announced at the 2002 National Business Aviation Association (NBAA) convention and is a derivative of the G100. Changes to the G150 include a wider cabin, upgraded avionics and a redesigned nose. The eight-passenger G150 has an additional 95 cubic feet of cabin space, including an extra 12 inches of width, 2 inches of height and 7 inches of length compared to the G100. The G150 has oval side windows like the G200 and a larger windshield in the cockpit. Collins Pro Line 21 avionics are installed instead of the G100’s Pro Line 4. The nose is modified to be more aerodynamic and looks more like that of the G200. The G150 is powered by two Honeywell TFE731-40AR turbofans. The G100 wings and empennage have been retained.
certification was obtained in 2006 and deliveries started the same year.
