Key Takeaways:

Gulfstream and Rolls-Royce successfully completed the first ultralong-range business jet flight by an OEM powered entirely by 100% Sustainable Aviation Fuel (SAF).
The flight demonstrated that current Rolls-Royce BR725 engines can operate on 100% SAF, laying the groundwork for future certification, despite current limits of 50% SAF blends.
This milestone significantly advances both companies' sustainability goals towards decarbonizing aviation and achieving net-zero carbon emissions using SAF derived from waste fat, plant oils, and plant-based sugars.

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.
