The Underground post

Back to Time Period
The Underground post

During the 1960s, as tensions between the East and West grew, Britain made some preparations for the event of nuclear attack.

Underground posts, manned by the Royal Observer Corps, were built in the countryside at approximately 10 miles apart. Each post was fitted with equipment to record the location and strength of a nuclear explosion. The post would also plot nuclear fall-out as it arrived and would alert the public using sirens and maroons. This model was used by the Exeter ROC in instructing its members about the workings of these newly-built posts; it was issued around 1965.
