No it isn't old chap.
As much as I agree it is an extremely worthwhile and important role, it is not the primary role of the RAF.
In suggesting otherwise, you are rubbishing the Typhoon by inference.
I agree we need a good CAS platform. Amongst other things.
Defence of UK airspace remains a vital role and a GR9/GR4/A-10 just doesn't cut the mustard in that respect.
