GE9X Engine
Born of power and efficiency
The largest and most powerful commercial aircraft engine ever built
The GE9X is the largest and most powerful commercial aircraft engine ever built, incorporating advanced technologies that enable more efficient, quieter flight with fewer emissions. Designed specifically for the new twin-engine Boeing 777X family, the GE9X is the most fuel-efficient engine in its class, delivering unmatched reliability and performance.

Purpose built for the Boeing 777X family of aircraft
The GE9X represents a multi-generational technology development chain, supported by millions of hours of field experience. We have pulled learnings from other engines, including the GE90 and GEnx, to enable a more efficient, more reliable, quieter engine with lower emissions.
GE9X
Combined with the Boeing 777X, the GE9X delivers the best airline economics and profitability via reduced fuel consumption, emissions, and associated costs, and lowest environmental impact.

Ceramic Matrix Composites provide greater durability
Expanded use of epoxy resin composites verse the GE90 is used for lighter weight and improved fatigue durability.
Engineered with the environment in mind
Environmental performance
The GE9X features the same world-class reliability as the GE90-115B, with noise and NOx emissions well below anticipated regulation standards.

Lower emissions: All emission values at or below current regulatory requirements. 50% lower emissions (CO, Particulate, NOx).
Quietest
Turbofan engine: Per pound of static thrust produced, the GE9X is the quietest turbofan engine GE Aerospace has ever produced, and is designed to meet current and anticipated next level of noise certification standards on the B777X Family.
There is no substitute that can achieve the combination of size, power and fuel efficiency of the GE9X. This engine will deliver unsurpassed value and reliability to our airline customers.
Tested, Validated, Certified
GE9X received FAA certification in September 2020
The GE9X has been through the most rigorous testing program of any GE commercial aircraft engine in history. The engine accumulated close to 5,000 hours and 8,000 cycles of ground testing plus 72 test flights totaling more than 400 hours on GE’s 747 Flying Test Bed.
