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.
In a wonderful piece of national 'peace dividend' cashing-in, while making a mockery of 'joined-up NATO defence planning', we closed down Saxa Vord on the Shetlands while the Danes removed the radar from the Faroe Islands, well and truly putting the 'gap' back in to the GIUK Gap! Since that far-sighted decision, the RAF has continued to toy with the idea of making further budgetary savings by removing more UK ASACS radars.
But radars don't look sexy at airshows (unless rotating on the top of an E3D, and even that's a minority view).
