Cold War Civilian Communications
Home Page

This website has become a fascinating repository of information on the U.K. Communications Networks, the United Kingdom Warning and Monitoring Organisation (U.K.W.M.O.) and Royal Observer Corp. (R.O.C.), thanks entirely to the wonderful feedback of information and photographs from visitors since its inception in 2001. I wish to express my thanks to all those who have helped over the years and encourage others to share anything they know as this might be the little missing piece of the jigsaw needed to complete the full picture.
The 30th September 2021, was the thirtieth anniversary of the standdown of the Royal Observer Corp. (ROC) and the United Kingdom Warning and Monitoring Organisation (UKWMO). After stand-down, the HANDEL warning system giving the four minute warning was turned off. Detailed descriptions of all these defunct systems are drawn from declassified documents, once protected by the official secrets act.
