The trouble with your analysis suggestions SLXOwft, by the time you've progressed with that lot, the airfields you've lost have gone forever. If you dared try and open any again because you were in a hurry to do so, the only thing to count will be the money you've wasted. What you suggest is a bean counter's dream and a military planner's nightmare. We're trying to be too modern and consumed by the idea that we should have progressed way beyond manned planes etc. Squeezing what's left onto very few bases is a problem for personnel, and I appreciate this kind of pure functional thinking has no room for things like Messing according to rank, but these things have their place.
Bases have a strategic importance within, even now and a role if only for dispersal, should it be required. You can't dismiss such things so sweepingly as all part of yesteryear.
After you've reduced the asset to such a cramped basing system and crowded airspace here and there, don't think the Dominic Cummings' won't come looking for more base closures again. Its gone way too far already. If you want a defence posture which tailor fits the country's needs, well there isn't one. The UK doesn't have a uniquely radical defence and security requirement diverse from the other NATO countries or anywhere else in the world.
