GE90 Engine Family

The Epitome of Aviation Engineering Excellence

The GE90 engine family stands as a pinnacle of jet engine innovation, designed by GE Aerospace for the Boeing 777 series. With thrust ratings spanning from 81,000 to 115,000 pounds-force, the GE90 engines are celebrated for their exceptional performance and reliability. They are the preferred choice for the 777-200, -200ER, and -300 variants, and are the exclusive engine option for the -200LR, -300ER, and 777F models. The GE90-115B variant, in particular, is recognized for its record-breaking thrust, making it one of the most powerful and efficient engines in commercial aviation.
