Royal Observer Corps

From Wikipedia, the free encyclopedia

ROC Crest. With its roots from the Elizabethan coast watchers organised and paid for by the County Sheriff to light and care for the beacons used to give warning of the approach of enemies – such as the Spanish Armada. The coast watcher holds aloft a torch, the whole encircled by a wreath of gilt laurel and surmounted by the royal crown, the motto being Forewarned is Forearmed.

The Royal Observer Corps (ROC) was a defence warning organisation operating in the United Kingdom between 1925 and 31 December 1995 when it was stood down. The Corps was manned mainly by civilian sparetime volunteers who wore a Royal Air Force style uniform and were latterly under the administrational control of RAF Strike Command and operational control of the Home Office. The 10,500 ROC volunteers were trained and administered by a small cadre of seventy uniformed full time professional officers under the command of a serving RAF Air Commodore.

In 1924 the introduction of the "Air Defence of Great Britain" led to the provision of a Raid Reporting System delegated to a committee with representatives from the Air Ministry, Home Office and the Post Office. This was later to become known as the Observer Corps and awarded the title Royal by King George VI in 1941 as a recognition of its service during the Battle of Britain. The corps was created to provide a system for detecting, tracking and reporting aircraft over Britain. During World War 2 it was complementary to and often replaced the radar system in that it provided an 'over land' element while radar handled the 'over water approach' requirement.

In 1955 the detection and reporting of nuclear blasts and fall-out was introduced. By 1965 the aircraft role was no longer needed and the corps formed the field force for the United Kingdom Warning and Monitoring Organisation (UKWMO) until both organisations were disbanded in the early 1990s when the Cold war ended.

[edit] Early days and the First World War

The ROC had its beginnings during World War I. At the beginning of the war the need for an air raid warning system was not envisioned, but raids by Zeppelin airships starting in 1915 indicated that a warning system was needed. A system of observers was soon organised with a series of some 200 posts established in strategic areas, initially these were manned by troops, but these were soon replaced by police, coordinated by area with telephone contact to anti-aircraft (AA) defences. This system proved to be reasonably successful in combating the Zeppelin.

In 1917 Germany started using fixed wing bombers and the number of airship raids diminished rapidly. To answer this new threat Major General Edward Bailey Ashmore ^[1], a First World War pilot and had later been in command of an artillery division in Belgium, was appointed to devise improved systems of detection, communication and control. A system to be called the Metropolitan Observation Service was created, this covered the London area, known as the London Air Defence Area, and was soon extended towards the coasts of Kent and Essex. The system met with some success and although it was not fully working until late summer 1918 (the last air raid took place on 19 May) the lessons learnt were to provide valuable grounding for later developments. Major General Ashmore is deemed to be the founder of what would become the Royal Observer Corps.

[edit] Between the wars

After the Armistice it was intended that the knowledge and skills learnt during the war should be kept alive. These plans came to nothing and by the end of 1920 all networks and associated anti-aircraft hardware had disappeared.

In 1922, responsibility for air defence was transferred from the War Office, which was responsible for the Army, to the Air Ministry. Major General Ashmore, who had been responsible for matters during World War I, now reported to a new Air Raid Precautions (ARP) committee set up in January 1924. Experiments were now carried out around Romney Marsh and the Weald. These were intended to optimise the arrangement of observation posts and control centres. In 1925 these experiments were extended to cover parts of Essex and Hampshire and by October a sound methodology had been worked out. On 29 October 1925 the Observer Corps came into official existence. Within a year four Groups existed in SE England, covering much of Kent, Sussex, Hampshire and Essex. The plan was that the country would be covered by 18 of these groups. The involvement and cooperation were needed between the Royal Air Force (RAF), the Army, the British police forces and the General Post Office (GPO), then responsible for the national telephone system.

In January 1926 observers were being recruited as special constables by county constabularies. Each post was to be manned by a sergeant and six constables, recruits were to be part-time volunteers with no pay, no uniform and no allowances; lapel badges would be issued, but would have to be paid for. In 1929 the control of the Observer Corps passed to the Air Ministry, although chief constables retained responsibility for personnel and recruitment matters.

During the 1930s the number of groups increased until, by 1936, England was covered south east of a line drawn from Flamborough Head to Poole Harbour. Also in 1936 Headquarters of the Observer Corps moved to its final home at RAF Bentley Priory. By 1939 practically the whole of Great Britain was covered, the western extremities of the West Country, Wales and Scotland were included in 1940, in 1941 the last group Portree was formed in the Western Isles

[edit] World War II

[edit] Preparation

At the end of September 1938 the crisis which resulted in the Munich Agreement led to the Corps being called out for a week. This exercise proved to be invaluable as it drew attention to organisational and technical problems and gave time for solutions to be sought. Exercises held throughout 1939 enabled necessary modifications to methods and structure. The Observer Corps would evolve over the coming years, a process aided by the keenness with which Corps members from every walk of life addressed the process.

The only uniform items issued to the observers were army steel helmets (with the letters 'O C' stencilled on the front and armbands also bearing the O C legend. High quality naval binoculars were issued. Observation posts often consisted of nothing more than a wooden garden shed located next to a telegraph pole so that a communications tap could be inserted onto the telephone line and linked to a centre via manual switchboards at local rural exchanges.

[edit] Early days of the war

On 24 August 1939 Chief Constables issued mobilisation notices to all members of the Observer Corps. War was eventually declared on 3 September, posts and centres would be manned continuously until 12 May 1945, four days after VE Day on 8 May 1945.

The first months of World War II were known as the Phoney War. There was little significant enemy aircraft activity over Britain. The Battle of Dunkirk started at the end of May 1940, Allied troops were cut off by the German army in north-east France. This resulted in the evacuation of British troops in Operation Dynamo which ended on 4 June. During this time the RAF lost 944 aircraft, half of these being fighters. Observer Corps posts in Kent and around the Thames estuary were able to play some part by plotting aircraft while they were over England. It was however an extremely useful period for training and practice which proved to be extremely valuable within a few months. Standard reporting posts were contructed, usually two storey with an open topped observation platform above a lower level crew rest room.

Obviously it was essential that observers could correctly identify an aeroplane. In 1939 aircraft recognition was not yet the highly prized skill it was to become in the Observer Corps. The other services felt that accurate identification was impossible. Observers realised that this was a deficiency and the raised profile of aircraft recognition was driven from below. Identification literature with aircraft silhouettes and data, started almost entirely as a private club initiative instigated by observers and only much later spreading to the armed forces.

[edit] Battle of Britain

After the Fall of France the German aim was air superiority over Britain, to be achieved by destroying RAF fighters in the air and on the ground, and by bombing aircraft factories. Winning the Battle of Britain, as it was soon called, was Germany's prerequisite in preparation for the invasion of Britain, Operation Sealion.

The British Chain Home  radar system was able to provide warning of enemy aircraft approaching the British coast, but once they had crossed the coastline the Observer Corps provided the only means of tracking them. During the period from July to October 1940 the Corps was fully stretched 24 hours a day plotting aircraft and passing this essential information to RAF groups and sectors. The Battle of Britain saw the start of the Blitz, the shift of German bombing from airfields to cities, the Observer Corps provided the information which enabled air raid warnings to be issued. The Blitz itself continued until early in the summer of 1941 and bombing on a reduced scale continued until March 1945.

After the successes of 1940 and early 1941 the corps was retitled the Royal Observer Corps (the ROC); it was to continue as a civilian organisation and be administered by the Royal Air Force, and for the first time women members would be recruited. Members of both sexes were employed in two forms: Class A who were required to work for 56 hours a week, and Class B members who undertook up to 24 hours duty per week. Initially the only uniforms provided were RAF overall boiler suits with an ROC breast badge, commonly referred to as the "soup plate" because of its size. Proper No 2 battledress uniforms were issued in a rolling programme over the next two years.

[edit] Seaborne observers

For the rest of the war the ROC provided an essential part of Britain's air defences. In 1944, during preparations for the invasion of France called Operation Overlord, a request for volunteers produced 1,094 highly qualified candidates, from which 796 were selected to perform valuable aircraft recognition duties as seaborne volunteers.

These Seaborne Observers were organised by Group Commandant C.G.Cooke and trained at the Royal Bath Hotel Bournemouth before the volunteers temporarily joined the Royal Navy with the rank of Petty Officer (Aircraft Identifier). The volunteers continued to wear their ROC uniforms, but wore SEABORNE shoulder flashes and a Royal Navy brassard with the letters RN. During the D-day landings two Seaborne observers were allocated to each warship of the US Navy and any armed merchantmen. The ROC volunteers were given control of each ship's anti aircraft batteries, thereby reducing the previously high level of friendly fire, or collateral damage incidents as they are now known. Their success is measured by a signal from Wing Commander P.B. Lucas, Air Staff Officer who reported:

"The general impression amongst the Spitfire wings, covering our land and naval forces over and off the beach-head, appears to be that in the majority of cases the fire has come from British Navy warships and not from the merchant ships. Indeed I personally have yet to hear a single pilot report that a merchant vessel had opened fire on him"

Twenty two Seaborne observers survived their ships being sunk, two lost their lives and several more were injured during the landings. The Seaborne operation was an unqualified success and in recognition, His Majesty King George Vl approved the wearing of the SEABORNE flash as a permanent feature of the uniform. In addition, ten Seaborne members were mentioned in despatches. After the invasion and just before his death Air Chief Marshal Trafford Leigh-Mallory wrote the following to be circulated to all ROC personnel:

"I have read reports from both pilots and naval officers regarding the Seaborne volunteers on board merchant vessels during recent operations. All reports agree that the Seaborne volunteers have more than fulfilled their duties and have undoubtedly saved many of our aircraft from being engaged by our ships guns. I should be grateful if you would please convey to all ranks of the Royal Observer Corps, and in particular to the Seaborne observers themselves, how grateful I, and all pilots in the Allied Expeditionary Air Force, are for their assistance, which has contributed in no small measure to the safety of our own aircraft, and also to the efficient protection of the ships at sea.

The work of the Royal Observer Corps is quite often unjustly overlooked, and receives little recognition, and I therefore wish that the service they rendered on this occasion be as widely advertised as possible, and all units of the Air Defence of Great Britain are therefore to be informed of the success of this latest venture of the Royal Observer Corps."

Today there is a Seaborne Observers’ Association for the dwindling number of survivors. Air Vice-Marshal George Black CB OBE AFC RAF (Rtd), a former Commandant ROC, is the honorary President.

[edit] Flying bombs

During Operation 'Totter' , the ROC fired ‘Snowflake’ illuminating rocket flares from the ground to identify V-1 flying bombs to RAF fighters.^[2]

[edit] Organisation and methods

The headquarters of each Group operated from a Centre and controlled about 30 to 40 Posts each of which would be some 10 km to 20 km from its neighbour. By 1945 there were 40 centres covering England, Wales and Scotland, controlling in total more than 1,000 posts, The ROC did not operate in Northern Ireland until 1954.

The Colchester (No 18) Group - Post organisation in 1944

If you know the height of an aircraft it is possible, from its horizontal bearing and vertical angle, to calculate a position. Posts were equipped with a mechanical sighting Micklethwaite post instrument mounted over a gridded map. After setting the instrument with an estimate of the aeroplane's height, the observer would align a sighting bar with the aircraft. This bar was mechanically connected to a vertical pointer which would indicate the position of the aircraft on the post map.

Observers in posts reported the map coordinates, height and number of aircraft for each sighting to their Centre. At each Centre plotters sat around a large table map, they had head sets continuously connected to a Cluster of posts, usually three in number.

The plotting table consisted of a large map with grid squares and posts marked. Counters were placed on the map at the reported positions, each of which indicated the height and the number of aircraft represented, a colour coding system indicated the time of observation in 5 minute segments. The table was surrounded by plotters, each communicating with a cluster of posts. Over time the tracks of aircraft could be traced, the colour coding enabled the extrapolation of tracks and the removal of stale ones. From 1942 long range boards were introduced to centre operations rooms, tellers in contact with neighbouring groups could handover incoming and outgoing tracks which were plotted on this map.

Duties in the operations room included: plotters working on the plotting table and on the long range board; tellers communicating with neighbouring ROC groups, with fighter operations rooms, with anti-aircraft and searchlight units; alarm controllers in contact with the police, with the national alert system, with the Ministry of Home Security and with local factories; an interrogator liaising with the ground controlled interception (GCI) radar units; and the Duty Controller, his assistant and a post controller who supervised the plotters and posts.

On 12 May 1945, when it was certain that all Luftwaffe aircraft were grounded, the ROC temporarily stood down, to be quickly re-activated to meet post-war threats.

[edit] The cold war years

[edit] A change of role

In September 1947, over a year after VE Day, the ROC held its first small scale exercise in southern England, which included for the first time substantial numbers of jet aircraft. Another year later the first large scale exercise took place; in the last two of its four days of this radar only was used. By the mid-1950s the greater speed of aircraft and the improved performance of radar led to a reduced need by the RAF for the ROC's services in tracking aircraft; another role in defence against nuclear weapons was announced in June 1955. The first significant exercise involving the ROC in handling nuclear data was in 1956. In 1957 the British government's policy became clear and reliance would be placed on the nuclear weapons, within ten years any pretence that there was an aircraft recognition and reporting role for the ROC had all but gone.

In 1957 the United Kingdom Warning and Monitoring Organisation (UKWMO) was set up under Home Office control. It was intended that UKWMO would provide civil and military authorities in Britain with information during a nuclear attack. The ROC would provide the first data on the positions and extent of the attack. This data would be used by UKWMO, in conjunction with weather information from the Meteorological Office, to produce a forecast of radioactive  fallout. As this fallout occurred its strength and position would be mapped using data from posts, enabling further fallout forecasts to be given.

In 1962 the Groups were reorganised with their number being reduced from forty to thirty one, with a further reduction to twenty five in 1968 with the Corps' coverage extended to Northern Ireland for the first time. It would now be necessary for Centres and posts to be occupied for between seven and twenty one days after any nuclear event. Age limits of 16 to 65 were introduced for the first time, some wartime observers having served into their seventies and eighties. Now service after the age of 65, where suitable local replacements could not be recruited, was extremely rare and had to be applied for on an annual basis together with medical certificates.

In the early 1970s the Royal Observer Corps was honoured by the RAF with the writing of its own dedicated march Skywatch which was composed by Wing Commander Roy Davies, then leader of the Central Band of the Royal Air Force. From 1978 the uncomfortable wartime "hairy mary" battledress uniforms were replaced in a rolling programme with modern zip fronted comfortable No 2 RAF uniforms (immediately christened as 'mothercare suits' by observers due to the shapeless and baggy jackets), shirts with collars attached, practical woollen jerseys and (additionally for post observers) new style green overalls and nylon foul weather suits.

[edit] The building programme

To enable the ROC to operate in a nuclear environment changes were necessary to both centres and posts to provide protection against blast effects and radiation from nuclear bursts.

Between 1960 and 1968 a countrywide building programme constructed a chain of 870 underground monitoring posts roughly ten square miles apart all over England, Scotland, Wales and Northern Ireland. The posts were excavated down to twenty five feet, a reinforced concrete monococque building was cast and bitumen tanked (or waterproofed), before the whole structure was recovered by a compacted soil mound. Entered down a steel ladder in a vertical shaft the posts provided a single room accommodation for three observers to live and work in and a separate toilet compartment with a chemical closet. Air was circulated from grilled ventilators at both ends of the post and electricity was provided by a 12 volt car battery charged occasionally by a portable petrol electric generator. New instrumentation detected the peak overpressure from any nuclear burst, photographic indications of the burst location and subsequent radiation levels. Conditions in these spartan posts was cramped, cold and in many cases also damp. It was fortunate for the volunteer observers that long operational occupation never became necessary.

ROC centres were renamed as Controls and provided with bomb proof nuclear protected buildings ^[3]. A small number were converted from suitable and existing Second World War anti aircraft operations rooms (AAORs), with the remainder specially constructed as above ground or semi-sunk blockhouse buildings to a standard layout, depending on the subsoil composition at the chosen sites. The controls provided living and operational accommodation for up to a hundred observers and the Home Office UKWMO warning team members. There were male and female dormitories, kitchen and canteen provision, life support systems and decontamination facilities together with a communications centre and a split level central operations room with balcony positions.

[edit] Nuclear Reporting Cells

During the 1970s, in addition to the post observers and control observers, a new class of observers were created to man specialist Nuclear Reporting Cells at selected major armed forces Headquarters all over the UK. These NRC observers provided the army, navy and air force with comprehensive visual displays and scientific interpretation of the information provided by the ROC controls. Their role combined basic ROC training and duties with some of the scientific skills and training of the Home Office warning teams. Higher levels of security clearance and specialist training were needed for the limited number of NRC observers.

[edit] Instrumentation

For the detection of nuclear bursts

• Atomic Weapons Detection Recognition and Estimation of Yield known as AWDREY was a desk mounted automatic instrument, located at controls, that detected nuclear explosions and indicated the estimated size in megatons. Operating by measuring the level of electro magnetic pulse (EMP) the instruments were tested daily by wholetime ROC officers and regularly reacted to the EMP from lightning strikes during thunderstorms. ^[4] AWDREY was designed and built by the Atomic Weapons Establishment at Aldermaston and tested for performance and accuracy on real nuclear explosions at the 1957 Kiritimati (or Christmas Island) nuclear bomb test (after being mounted onboard a ship). Reports following a reading on AWDREY were prefixed with the codeword "Tocsin Bang".

• The Bomb Power Indicator or BPI consisted of a peak overpressure gauge with a dial that would register when the pressure wave from a nuclear explosion passed over the post. When related to the distance of the explosion from the post this pressure would indicate the power of the explosion. Reports following a reading on the BPI were preceded by the codeword "Tocsin".

• The Ground Zero Indicator, or GZI or shadowgraph, consisted of four horizontally mounted cardinal compass point pinhole cameras within a metal drum, each 'camera' contained a sheet of photosensitive paper on which were printed horizontal and vertical calibration lines. The flash from a nuclear explosion would produce a mark on one or two of the papers within the drum. The position of the mark enabled the bearing and height of the burst to be estimated. With triangulation between neighbouring posts these readings would give an accurate height and position. The altitude of the explosion was important because a ground or near ground burst would produce radioactive fallout, whereas an air burst would produce only short distance and short lived initial radiations (but no fallout).

For the measurement of ionising radiation

• The Radiac Survey Meter No 2 or RSM was a 1955 meter which counted the particles produced by radioactive decay. This meter suffered from a number of disadvantages: it required three different types of obsolete batteries, it also contained delicate valves that were liable to failure and it had to be operated from outside the protection of the post. These were favored as they had been tested on fallout in Australia after the Operation Buffalo nuclear tests, and remained in use until 1982 by commissioning a manufacturer to regularly produce special production runs of the obsolete batteries. Within the ROC the RSM was superseded in 1958 by the FSM and the RSM retained only for post attack mobile monitoring missions.

• The Fixed Survey Meter or FSM introduced in 1958, could be operated from within the post with a cable leading to the detector mounted externally and protected by a polycarbinate dome. The FSM used the same obsolete high voltage batteries as the RSM. In 1985 this instrument was replaced by the PDRM 82(F).

• The PDRM82 or Portable Dose Rate Meter and the desktop fixed PDRM 82(F) version of the same meter, that were manufactured by Plessey and introduced during the 1980s, gave more accurate readings and used standard 'D' cell torch batteries that lasted many times longer, up to 400 hours of operation. The compact and robust instruments were housed in sturdy orange coloured polycarbinate cases and had clear liquid crystal displays.

• The Dosimeter pocket meters were issued to individual observers for measuring their personal levels of radiation absorption during operations. Three different grades of dosimeter were used, depending on ambient radiation levels. The original hand wound and tempremental dosimeter charging units were replaced during the 1980s by battery operated automatic charging units.

[edit] Communications and modern developments

Initially communications between posts and controls were by ex-army head and breast sets over above-ground telephone lines that had to be manually switched by Post Office engineers prior to exercises and operations. The head and breast sets were replaced in 1964 by metal housed “Teletalk” units that only permitted one way communications when the talk switch was depressed. The teletalks again used manually switched telephone lines, but with integral transistorisation to boost transmission and reception power. During the 1980s a new design of teletalk was introduced by British Telecom together with underground, permanently wired, landline connections that were hardened against the effects of Electromagnetic pulse (EMP) from nuclear bursts.

Posts were organised in “clusters” of three, four or five posts with one in each cluster designated as the “Master Post”. To cover the possibility of a cluster being disconnected from its parent control, the master posts were provided with radio equipment that was capable of communicating with the parent control and up to three adjacent controls on different frequences.

Inter-group control to control exchange of burst and radiation data was initially as voice messages by "tellers" over telephone lines between adjacent groups. In 1971 this was replaced by punched tape data exchanges by telegraph teleprinters located in the communications centre. Between 1981 and 1985 the teleprinters were replaced again, this time with modern computerised AD9000 message switch equipment, operating over a permanent and EMP hardened landline network that permitted direct communication with every other group in the country. In the late 1980s the manually operated PMBX switchboards were replaced with computerised direct dial SX2000 equipment.

During the years immediately before the announcement of the Corps’ standdown there were trials in progress that would have provided monitoring posts with remotely operated above ground petrol generators that would provide constant electricity, “black” heaters to provide a warmer environment underground and new sealed ventilators to allow air changes without opening the post to a contaminated air flow.

[edit] ROC Association

In 1986 the Royal Observer Corps Association (ROCA) was established with membership open to both serving and ex-observers of the ROC to provide close and continuing links between the Corps and its previous members. The association was organised on a regional basis with a chapter in each of the twenty five groups. Each chapter produced and distributed a monthly or quarterly magazine to keep the membership informed of developments and both local or national news. ^[5]

The stated aims of the Association is to:

• To maintain esprit de corps and promote comradeship among ex-Corps members.
• To help ex-Corps members and their dependants who are in need, to obtain assistance from the Royal Observer Corps Benevolent Fund. ^[6]
• To raise money for the Royal Observer Corps Benevolent Fund.
• To give support to any future re-establishment of the Royal Observer Corps as a voluntary organisation.
• To represent the interests of members with other national organisations.
• To preserve the heritage of the Royal Observer Corps including memorabilia and artifacts.

The Association has actively continued since the ROC disbanded and still provides an additional contact point for ex-observers or their dependants. ROCA also organises the annual reunion weekend each October at a suitable holiday resort hotel and provides an ROC contingient to the annual Remembrance Sunday event at the Cenotaph in London's Whitehall.

Many control and post crews have formed sub-chapters of ROCA and have continued to meet on a weekly or monthly basis for the sixteen years since stand down. They meet at local RAFA Clubs or hotels and invite interesting visiting speakers, or arrange visits to local places of interest. Local ROCA members turn out for Remembrance Sunday parades all over the country. Ex members are permitted to wear the ROC beret and cap badge, together with any medals.

During early 2008 the ROCA chapters in 4 Group Colchester and 17 Group North Wales closed due to the lack of organising committee members. ROCA members in those areas may join adjacent group chapters of the association.

[edit] After the Cold War and the Corps stands down

The main field force of the ROC's monitoring post and group control personnel were stood down on 30th September 1991 and the ROC's original 1966 Royal Banner was laid up at St Clement Danes Church in the Strand, London where it remains on display, a new banner having been presented by HM Queen Elizabeth II in July 1991 at a Royal Review of the ROC. The Corps was disestablished along with the UKWMO following what was described by the Queen at the Royal Review as "the end of the Cold War" and linked to a Government press release that referred to "possible future developments and improvements in automated nuclear explosion and fallout detection from remote sensors".

ROC Banner is marched into St Clement Danes church, London for laying up on 29 September 1991. The banner bearer was Observer Lieutenant Terry Giles of No 1 Group Maidstone

Only the Nuclear Reporting Cell (NRC) elements of the Corps remained in service, working alongside major armed forces headquarters and they entered a new and highly-uncertain phase. Reduced to less than 300 members in total over the whole UK, the original retained NRCs now found themselves tasked with the daunting challenge of providing a comprehensive Nuclear, Biological and Chemical (NBC) warfare analysis and warning service for the Military Home Commands, on a reserve-manned basis as NBCCs but without the countrywide flow of data from posts and controls.

The removal of any Home Office involvement in the ROC from 1991 onwards resulted in the "Remnant Elements" becoming effectively a single reserve Directly Administered Unit within RAF Strike Command (RAFSTC), commanded by a Group Captain (General Duties Branch). All still-serving members were required to remove their original ROC Group designations from their RAF uniforms, and to accept moves towards a change in conditions of service during any Transition-To-War (TTW) that would make them effectively members of the Royal Auxiliary Air Force (RAuxAF), with protected rights, and closer links were made with the war-appointable flights of the Royal Air Force Volunteer Reserve (RAFVR).

Despite having successfully built upon the extensive NBC reporting trials, undertaken with the RAF Regiment and meeting full NATO standards and evalutions (STANAGs and OPEVALs), the conclusion reached by the UK MoD was that retention of the Corps in its NBC Cell role was "desirable, but not essential in the existing format". As a consequence, the remaining part-time members of the ROC were stood-down on 31 December 1995 after a laying-up ceremony for the 1991 ROC Banner in the Rotunda at RAF College Cranwell in Lincolnshire on 8 Dec 1995. The ROC Banner remains on display in the RAFC Cranwell rotunda alongside other stood-down Air Force units and squadrons that are subject to liability for reactivation in the future. Headquarters ROC at RAF Bentley Priory finally closed on 31 March 1996 after all administrative winding up tasks were completed.

Several monitoring posts across the UK have been bought by ex-observers, re-equipped and opened as permanent amateur museums. Most of the control buildings have been sold into private ownership and converted to other uses or demolished. HQ 20 Group York's semi-sunk control building has been adopted by English Heritage and is open to the public in Acomb, York as a museum of the Royal Observer Corps' cold war activities (10am till 5pm Saturdays, Sundays and Bank Holidays. Weekday visits only with prior booking).

[edit] ROC rank structure and details

ROC Rank	Insignia	Abbreviation	RAF Equivalent	Whole Time Appointments	Sparetime Appointments	Notes
Senior Officers
Air Commodore		Air Cdre		Commandant ROC		A serving RAF (General Duties) Officer. With only two exceptions during the ROC's history all Commandants were ex-Pilots. Until 1978 the majority of the Air Commodores were in their final appointment before retirement. After 1978 many went on to Air Vice Marshal rank or higher after their ROC duties. A rank of Observer Commodore would have been held if an ROC officer had ever commanded the corps
Group Captain		Gp Capt		Commandant ROC		A serving RAF (General Duties) Officer. The ROC was commanded by a Group Captain between 1992 and stand down of the NRCs in December 1995. Royal Observer Corps officers' rank braid was identical to RAF braid, but redyed midnight black after manufacture to remove the pale blue centre lines.
Observer Captain	Four midnight rings	Obs Capt	Group Captain	Chief of Staff	Area Commandant (5)	The most senior rank held by a member of the ROC. The wholetime appointment was known as Deputy Commandant ROC between 1941 and 1983. The sparetime area commandant, Observer Captain Joyce Shrubbs MBE, was the only female to hold the rank in the history of the ROC.
Observer Commander	Three midnight rings	Obs Cdr	Wing Commander	Senior Admin Officer HQROC Senior Ops Officer HQROC Deputy Area Commandant (5)	Group Commandant (25)

The problem had been that Squadron Leader did not convert comfortably to Observer Leader, which sounded like something more akin to a Boy Scout troop. The Area Staff Officers were known as Area Training Officers from 1941 until 1975.
Junior Officers
Observer Lieutenant	Two midnight rings	Obs Lt	Flight Lieutenant	Ops Trg 2 HQROC Admin Officer HQROC Group Staff Officer (25)	Crew Officers NRC Officers Group Officers	The Group Staff Officers had been known as Group Training Officers until 1975. Sparetime officers received this promotion on merit. Obs Lts were often mistaken as Air Commodores by RAF airmen when in shirtsleeve order on RAF stations, the two midnight bands separated by a band of pale blue shirt material. Obs Lt was the entry level rank for wholetime ROC officers who attended the four week long Specialist Entrant and Re-entrant (SERE) Officers Course at the RAF Staff College Cranwell.
Observer Officer	One midnight ring	Obs Off	Flying Officer		Crew Officers NRC Officers Group Officers	Basic rank for a sparetime officer. All officers wore small gold "ROC" titles on both lapels of the raincoat, No 1 Dress jacket, No 2 tunic and No5 Mess Kit. The beret or forage cap badge changes from silver to gold. As uniformed civilians ROC officer rank was held under Royal Warrant rather than a Queen's Commission. ROC officers were subject to a rather odd combination of Queens Regulations for the RAF and Civil Service Staff Regulations.
Other ranks

[edit] Uniform notes

• When the ROC was first issued with uniforms in 1941 the RAF was able to provide the majority of the uniform items but held insufficient stocks of RAF blue berets. However the army had a surplus of Royal Tank Regiment berets, so the ROC was issued with the black army berets that remained part of the corps' uniform throughout its history.
• There was a similar shortage of sergeant and corporal stripes. However, there was a large surplus of rank badges for the quasi-military Royal Canadian (Volunteer) Storekeeper Corps serving during the war in UK dockside warehouses. The badges of bars within laurel leaves were adopted and Chief Storekeeper became Chief Observer and Leading Storekeeper became Leading Observer. The four bar rank of Master Storekeeper was considered but discounted. The four bar rank was again under consideration in 1990 to create RAF Warrant Officer equivalent Master Observer assistants to Crew, Group and NRC officers, but the decision was overtaken by the stand down announcement.
• Many observers joined the ROC after service in other armed forces. Aircrew brevets from the RAF, Army Air Corps and Royal Navy Air Service were permitted to be worn on ROC uniforms along with any medal ribbons from British or Empire (later Commonwealth) countries. Other permitted badges were specialist ‘trade’ badges such as parachute brevets, marksmen badges, radio operator badges etc.
• The 800 volunteer observers who served on board ships during the D-Day landings were entitled to wear a Seaborne shoulder flash for the remainder of their ROC career, even when promoted to officer ranks. There were a handful of Seaborne observers still in service when the majority of the corps stood down in 1992, many having lied about their ages in 1941 to make themselves older than they really were.

[edit] Royal Observer Corps Medal

Royal Observer Corps Medal

Prior to the Second World War observers were employed by police forces and qualified for the award of Special Constable Long Service Medal for twelve years continuous service. That qualification ceased in 1941 when RAF Fighter Command took control of the ROC.

In 1950 His Majesty King George Vl granted permission for the award of the Royal Observer Corps Medal for twelve years continuous service in the corps. Each subsequent service of twelve years was recognised by the award of an RAF eagle clasp sewn to the medal ribbon. Wholetime officer service counted for half qualification, therefore requiring twenty four years service to qualify for a medal or clasp, but with any previous sparetime service counting in full.

The medal was cast in a silver coloured cupronickel metal with the Monarch's head and since 1953 the legend ELIZABETH II DEI GRATIA REGINA F:D: on the obverse and the ROC crest, motto and the words Royal Observer Corps Medal on the reverse. The recipient's rank, initials and surname was stamped into the rim. The medal ribbon was a mix of pale blue, dark blue and silver vertical stripes, representing the pale blue of the daytime sky with a seachlight in a night sky at its centre.

The medal is suspended under an articulated brooch consisting of the RAF eagle.

Miniature ROC medals were eventually licenced and manufactured and may be worn at formal Black Tie events where the invitation indicates that medals are allowed.

[edit] ROC '"Spitfire" proficiency badging

ROC Red Spitfire badge awarded for 25 master test passes, the badge also appeared in pale blue and gold versions

ROC other ranks were entitled to wear the "Spitfire" proficiency badge to mark successes in the annual "Master Test" examination. Initially a test of aircraft recognition with photographic slides projected onto a screen by a "Flash Trainer" projector, between 1956 and 1966 the test became a mix of aircraft recognition and written answers to questions relating to the nuclear detection role. Latterly the master test was a 100 question multiple choice test and separate specialist papers were provided for post, crew and NRC observers.

There were four levels of result ranging from fail, basic pass, intermediate pass to master pass. A score of 90% was required for the award of a master pass. The first time a master pass was achieved the Blue Spitfire badge was awarded, each subsequent five passes rated a blue star badge until the twenty fifth pass when a Red Spitfire badge replaced the original blue spitfire. After the award of the red spitfire each subsequent five master passes was recognised by a red star badge until the fiftieth pass when the red spitfire was replaced by a Gold Spitfire, the gold spitfire badge only being introduced in 1989.

The age limits of service meant that fifty was the maximum number of passes possible for any observer to achieve, but needed a master level pass during every year of an observer’s ROC service. Only a handful of gold spitfire badges were ever awarded.
