For a lot of interesting background to Britain's <GW Bush> Noocular Detergent </GW Bush>, I'd recommend a read of The Secret State: Whitehall and the Cold War by Peter Henessey.
(Penguin Books; ISBN: 0141008350)
In it, there's list of assumed UK targets from about 1968 in which each V force base and dispersal would be thoroughly dealt with.
Mark.
