There are many high-value targets in Britain (like RAF Fylingdales, RAF Mildenhall, and RAF Lakenheath) that would then have to be struck in a conventional manner in this plan, though a nuclear strike would be far more effective (and, as the plans show, a preferable option for the Soviet leadership as shown by their strikes in Western Europe). The plan also indicates that USAF fighter-bombers, primarily the long-ranged F-111, would be employed in nuclear strikes, and that they would launch from those British bases.[1][2]
