The MN ordered 37 Rafale Ns for the CdeG. I would expect a similar but slightly larger number ordered for the FAA. 800/801 are now going to spend most of their time at sea until QE is launched and the transfer of personnel to F35 and the new carriers begins in earnest. Who said that we would ever have more then one CVF operational in a fixed wing role? I don't see that anywhere in any official statement and certainly the Navy never thought so.
Post Herrick the role of the RAF's share of JFH is less clear/justifiable in the current financial climate.
