There were wartime bases in Scotland that have gone. My Dad flew from Tain occasionally, and once crashed at Sumburgh, while there was Turnhouse, Dyce, etc. But Scotland seems to have escaped late- and post-Cold War cuts entirely unscathed, when the strategic rationale for ASW at Kinloss and for AD at Leuchars has vanished.
The logic of locating JSF as far as it's physically possible to get from the carriers it will serve also escapes me.
And on top of all that, there seems to be a slow but inexorable drift towards greater devolution for the 'Porridge Wogs' and with that in mind, it would seem sensible to limit the amount of national infrastructure on territory that may one day be part of some-one else's nation. Especially if the cost of doing so is that we throw away infrastructure on our own soil.
