Question to the Ministry of Defence:
To ask the Secretary of State for Defence, what estimate he has made of the cost differential of powering RAF flights by sustainable fuel compared with traditional fuel.
While the RAF conducted a test flight on 15 November 2022 using 100% Sustainable Aviation Fuel, we have made no estimate of the cost differential for all RAF flights to use such fuel as it is not available at scale and is not yet manufactured in industrial quantities.
