Royal Air Force successfully completes Voyager air-to-air refuelling flight on 43% SAF

In the UK, the Royal Air Force has successfully completed a Voyager air-to-air refuelling flight, powered by an approximately 43% blend of Sustainable Aviation Fuel (SAF).

Flying from RAF Brize Norton, over the North Sea and via Farnborough on its return home, the Voyager aircraft also undertook air-to-air refuelling with Typhoons, as part of planned training.

Made from waste-based sustainable feedstocks, such as used cooking oil, SAF reduces lifecycle carbon emissions by up to 80% compared to traditional jet fuel and will be key to reducing the RAF’s reliance on global supply chains and fossil fuels, while improving operational resilience.

This significant moment follows a series of recent milestones achieved by the RAF towards a sustainable aviation future, including the world first RAF Voyager flight fueled by 100% SAF.
