Radar coverage?
Sitting here on a wet Sunday afternoon reading the broadsheets two questions come to mind:
I seem to recall that as part of our cashing in of the "peace dividend" UK plc closed a number of early warning radar sites up in the North of Scotland and various islands as the USSR and it's threat had disappeared never apparently to return.
I've also read the RAF has been unable to keep its Sentry fleet updated to the latest spec and one of the airframes is no longer airworthy!
Assuming one or both of these statements is correct (from open sources) how secure is UK airspace from Russian visitors should the wheel start to fall off?
