The United Kingdom Warning and Monitoring Organisation (UKWMO) was a British civilian organisation operating to provide UK military and civilian authorities with data on nuclear explosions and forecasts of fallout across the country in the event of nuclear war.[1]

The UKWMO was established in 1957 and funded by the Home Office and used its own premises which were mainly staffed by Royal Observer Corps (ROC) uniformed full-time and volunteer personnel as the fieldforce. The ROC was administered by the Ministry of Defence but mainly funded by the Home Office. The only time the combined organisations were on high alert in the Cold War was during Cuban Missile Crisis in October and November 1962. The organisation was wound up and disbanded in November 1992 following a review prompted by the government's Options for Change report.
Its emblem-of-arms was a pair of classic hunting horns crossing each other, pointed upwards, with the enscrolled motto "Sound An Alarm", a title also used for the latter of two contemporary public information films (the earlier one was called "Hole in the Ground"). Members of the UKWMO qualified for the Civil Defence Medal for fifteen years continuous years service, with a bar for each subsequent twelve years.
The United Kingdom Warning and Monitoring Organisation had five main functions in the event of nuclear war. These were:
Headquarters UKWMO was located in a converted barracks building at Cowley Barracks in Cowley, Oxfordshire,[2] and was headed by a Director and Deputy Director supported by a small administrative staff. Five professional Sector Controllers and five Assistant Sector Controllers were co-located at the five UKWMO Sector Controls.
At each of the twenty five UKWMO group controls[3] the UKWMO was represented by volunteer and specially trained members. In the event of war the senior UKWMO volunteer present would command the group as Group Controller. Assessing the nuclear burst and fallout information and data provided by the ROC was a team of ten or more Warning Officers led by a Chief Warning Officer.
The members of the warning team were recruited from mainly local secondary school science teachers, or commercial engineers and technicians with a scientific education and background. They trained every two weeks from printed materials provided by the Home Office scientific branch and through lectures or practical training organised by the Assistant Sector Controller who was the area UKWMO training officer.
The Director UKWMO was located at the United Kingdom Regional Air Operations Command (UK RAOC) at RAF Booker tasked with instigating the four-minute warning.[4] The Deputy Director would be located at a standby UK RAOC, described at the time as being "elsewhere in the UK". It's since been revealed as being at Goosnargh, Lancashire, within the UKWMO Western Sector nuclear bunker. Warnings were instantly distributed around the country by the Warning Broadcast System via 250 Carrier Control Points located at major police headquarters and 17,000 WB400 (later WB1400) carrier receivers in armed forces headquarters, hospitals, post offices, ROC posts and private homes in remote rural areas where hand-operated sirens replaced the power sirens in the urban towns.
Sparetime warning team members were activated, through a rehearsed transition to war telephone calling card procedure, by wholetime Royal Observer Corps officers located at the twenty five group headquarters. UKWMO communications used private wires (PWs) (permanently available and with greater protection) or emergency circuits (ECs) (switched for exercises or in the event of an emergency) for data and voice with a radio back up option. Some other UKWMO telephone lines and the warning broadcast system were protected by the Post Office's Telephone Preference Scheme that kept the lines active while the general public's system could be progressively attenuated under wartime regulations.
Both wholetime and sparetime UKWMO personnel undertook specialist residential training at the Emergency Planning College, The Hawkhills, Easingwold, Yorkshire. Several major war simulation exercises were held each year 2 x WARMON (Warning and Monitoring) one day UK exercises and the two-day INTEX (International exercise) along with other NATO countries.
Four times a year minor and limited exercises called POSTEX were held on a stop – start basis across three evenings of a week, Monday to Wednesday. Realistic simulation material was provided for realtime simulations of a nuclear attack.
Approximately every four or five years each group was subjected to a "no notice" and in depth assessment similar to an RAF "TACEVAL" or Tactical Evaluation, where a mixed team of UKWMO and ROC full-time staff would appear and evaluate all aspects of the group's planning and operations under realistic wartime conditions over a period of 48 hours.
A large amount of work was completed from the mid 1980s to bring the UKWMO up to date. Modern detection instruments were provided to the ROC together with back up detectors at certain Sector or Group Controls known as Atomic Weapons Detection Recognition and Estimation of Yield (AWDREY) equipment. Updated warning equipment was installed in most government buildings, nuclear bunkers, armed forces HQs, police and fire stations and private houses in remote areas. Major police stations were used as the area control points for power operated sirens, so these were equipped with new WB1400 carrier control warning equipment.[5] If a warning was received then the police could operate the sirens via remote control, the carrier warning signal did not automatically operate the warning sirens (a few of which were those used in the Second World War). Many of the sirens are still in operation in coastal areas and are now used for emergency flood warning. Between 1985 and 1990 all communications links used by the warning system, the UKWMO and the ROC were upgraded and hardened against the effects of electromagnetic pulse damage. Point-to-point SX2000 automated telephone exchanges were installed in the UKWMO Sector and Group Controls and old fashioned telegraph equipment was replaced with modern computerised message switching equipment.
Ballistic missile air raid warnings for the UK would have originated from the shared UK/USA Ballistic Missile Early Warning System in England, (the site is now upgraded and still operational at RAF Fylingdales, on the North York Moors) and disseminated through UKRAOC to the carrier warning system. This was commonly, and slightly erroneously, known as the Four minute warning.
The Civil Defence Medal was instituted March 1961 and awarded for 15 years service in a variety of different organisations including; Auxiliary Fire Service, National Hospital Service Reserve, Civil Defence Corps and the United Kingdom Warning and Monitoring Organisation.
UKWMO training effectively ceased in the summer of 1991 after the Home Secretary's stand-down announcement. When the UKWMO was disbanded, and the ROC stood down, the government referred to "possible future developments and improvements in automated nuclear explosion and fallout detection from remote sensors", but it is unlikely that any such system has yet to be developed or installed. Civil nuclear defence since 1992 has been devolved to UK local authorities as an addition to their routine emergency planning responsibilities and under direction of the government's Civil Contingencies Secretariat but the four-minute warning air raid alert system no longer operates.
