Royal Observer Corps
The Royal Observer Corps (ROC) was a civil defence organisation intended for the visual detection, identification, tracking and reporting of aircraft over Great Britain. It operated in the United Kingdom between 29 October 1925 and 31 December 1995, when the Corps' civilian volunteers were stood down. (ROC headquarters staff at RAF Bentley Priory stood down on 31 March 1996). Composed mainly of civilian spare-time volunteers, ROC personnel wore a Royal Air Force (RAF) style uniform and latterly came under the administrative control of RAF Strike Command and the operational control of the Home Office. Civilian volunteers were trained and administered by a small cadre of professional full-time officers under the command of the Commandant Royal Observer Corps; latterly a serving RAF Air Commodore.
RAF Holmpton
Throughout its years as a Radar Station and through the years of Support Command & CCIS, the site also contained an operations area for the Royal Observer Corps (ROC) and although the Corps was 'stood down' in 1992 with some ROC units remaining as NBC cells until the end of 1995, one last Monitoring Unit remained at RAF Holmpton until December 1997, during the planning and implementation of a new electronic monitoring system. This made RAF Holmpton the very last place in the UK where any members of the Royal Observer Corps ever served, and is a unique part of the site's history. In 1997 this project was abandoned and the site was then maintained under contract until 2003 by AQUMEN Defence. During this time it was used for occasional training by the RAF Regiment & the TA. In 2003 the site was leased for 25 years by the Ministry of Defence to RL(FRAFS)BLC Limited and the day-to-day management passed to HIPPO (The Holmpton Initiative Project Planning Office). By late 2003 plans were underway for a public exhibition on the site which opened to visitors in 2004.
