Key Takeaways:

A Gulfstream G650, powered by Rolls-Royce engines, successfully completed the first flight of an ultralong-range business jet fueled entirely by 100% Sustainable Aviation Fuel (SAF).
This test demonstrated that current Rolls-Royce engines can operate on 100% SAF as a "drop-in" fuel, even though they are currently certified for blends up to 50%.
The flight significantly advances Gulfstream and Rolls-Royce's sustainability goals, laying critical groundwork for moving 100% SAF towards certification and contributing to aviation decarbonization.

A Gulfstream G650 with twin Rolls-Royce powerplants in special testing mode recently departed Savannah, Georgia, fueled on 100 percent sustainable aviation fuel (SAF), according to the aircraft manufacturer.

The flight advances both Gulfstream’s and Rolls-Royce’s sustainability goals, and also marks the first time an ultralong-range business jet flight by an original equipment manufacturer was fueled completely by SAF, according to Gulfstream.
