Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what recent discussions he has had with aircraft manufactures about the safe use of (a) sustainable and (b) synthetic fuels in the RAF.

The Ministry of Defence (MOD) has discussed the use of sustainable and synthetic fuels in air platforms over a number of years. These discussions enabled the Royal Air Force (RAF) to fly the UK's first military air transport flight using 100% sustainable aviation fuel on one of their operational Voyager aircraft. This was a joint endeavour between the MOD and industry partners, Airbus, AirTanker and Rolls-Royce, with the fuel supplied by Air BP.
