UK’s RAF achieves SAF air-to-air refuelling of Typhoon and C-130 Hercules aircraft

In the UK, The Royal Air Force has used sustainable aviation fuel blended with regular jet fuel to achieve the first sustainable aviation fuel blend air-to-air refuelling of a Typhoon and C-130 Hercules aircraft.

A RAF Voyager delivered the fuel to the Typhoon and Hercules. The Voyager was previously used in successful initial trials in November 2022 where it flew on 100% sustainable aviation fuel. The leftover fuel from the Voyager trial was mixed with regular fuel at around 46-48%. The RAF worked with Air BP to re-certify the fuel and achieve the required standards needed for a safe and effective mission.
