Until I was about 20 I lived only 3 miles away from a Regional Seat of Government bunker. It was reasonably well known in the village what was going on and the understanding was that we'd be fried in the first strike. Some years later and as the threat diminished whilst more information was made public, it transpired that this RSG was for a period of time the place where government ministers would be evacuated if Turnstile etc were deemed infeasible.
I have a copy of an autobiography from a Russkie in the upper echelons of the Rocket Corps and he talked about some of the first strike targets - was weird to hear the name of this RSG being targeted with a multi-MT strike.
When I was in my mid-teens myself and some mates gained access to the bunker which was pretty cool. During the mid-80s a defence review decided that the bringing the whole complex up to current standards was too expensive, so they partitioned off a smaller central chunk of the complex and made that compliant as a RGHQ, but basically left the rest to grow mould, making it pretty easy to get in.
At the time we didn't really realise how lucky we were to get chance to explore something in such good (literally untouched) condition. Over the following years it got progressively trashed until the Govt Estates sold it off for storage. There is an old paper photograph of me somewhere standing inside one of the tunnel entrances surrounded by a load of 80's Ban The Bomb style protester signs. Got to say their painting skills were a bit poor
but it was a bit weird seeing all these protester's signs inside one of the security offices inside the bunker.
And many years later I found some suggestions that in-transit warheads were overnighted here. The suggested location (don't know if anybody ever found conclusive evidence, but based on the geographical location it made sense as a secure overnight transport stop) inside the bunker where the trucks would stop is also the scene of another snapshot of me
We eventually got caught, but it was nothing like nowadays where you'd probably be up before an
in camera court session charged with terrorism offences
A family member was responsible for the NHS services in this region upto the last 90s and had regular Cold War Goes Hot drills BITD. Hearing about them made pretty grim listening - the basic plan was that on a best-efforts basis vans would turn up in major population centres that were still standing post-strike and hand out meds which were nothing more than thinly disguised suicide kits, the logic being that these were the people who couldn't be saved due to their exposure.
Grim times.
