The RAFAC does not have a strategic footprint. All of the units that exist now are there as an accident of history. They are the ones that have survived since the end of WW2.
In my wing since I was a cadet 5 units have closed in my wing, 4 because of lack of staff or cadets and one because the RAF station it was on became a Army camp. The units that have survived are either in the ones in the largest towns or cities or in the past have kept going because they have had good staff and have had good numbers or rescued by parachuting staff in from another unit having the big relaunch.
As a result the units are not all in the largest population centres but where they have survived. There are a few town of over 10,000 people without a Sqn, a few small villages of less than 2500 inhabitants with units and quite a few town of between 5,000 and 10,000 without squadrons. E.G. A town of 14,000 people without a sqn and 20 miles away a village of less than 2,000 inhabitants with a sqn. Then there are 2 units who are 5 minutes apart because over the years they have moved from their original locations to where they are now on the closest edge to each other of their towns.
With the review of the strategic footprint will squadrons be moved to larger town or new units opened. Will there be a minimum distance between units and rationalisation take place. Will account of the travel times of the cadets to the new unit be taken into account.
