SASless,
Seeing as we only have a total of 18 F-35B Lightning FG1's at the moment and the carriers are not even operational, we don't need to, BUT, WHEN both are fully operational, and the F-35B squadrons are formed, yes, the RN could easily support both carriers with T45/T23 and SSN and RFA tankers and Store ships along with RAF P-8A and Typhoon support to boot.
