The Defence Intelligence Fusion Centre (DIFC) is based at RAF Wyton in Cambridgeshire. Largely created from the staff of the National Imagery Exploitation Centre (formally known as JARIC) and then known for several years as the Defence Geospatial Intelligence Fusion Centre, it can trace its history back to clandestine reconnaissance operations at the beginning of World War II by Sydney Cotton on behalf of MI6 and then MI4, and the formation of the Allied Central Interpretation Unit at RAF Medmenham (sister to Bletchley Park). Today, DIFC's role has grown beyond just imagery intelligence. Part of the Joint Forces Intelligence Group (JFIG) within Defence Intelligence, DIFC’s primary role is to support Defence planning, current operations and the intelligence assessment process. DIFC still provides specialist imagery intelligence, but also conducts multi-disciplinary intelligence fusion for the armed forces and other UK Government partners. The integrated multi-disciplinary Task Groups at DIFC use data and reporting from various sources (including satellite imagery), together with other advanced technologies, to provide critical information and over-watch to tactical, operational and strategic decision makers. DIFC is a joint service and civilian organisation under the command of an RAF Group Captain.
Following a series of successful covert air reconnaissance operations run by the United Kingdom’s Secret Intelligence Service (MI6) prior to World War II, the Photographic Development Unit (PDU) was established on 19 January 1940 (codenamed MI4) and later renamed Photographic Interpretation Unit (PIU) on 11 July 1940.
Through a series of War Ministry reorganisations the PIU was renamed the Central Interpretation Unit (CIU) on 7 January 1941 and changed again to the Joint Air Photographic Intelligence centre (UK) JAPIC[UK] in August 1947. On 17 December 1953 the unit was given the name of Joint Air Reconnaissance Intelligence Centre [UK] - JARIC[UK].
The JARIC Photographic Wing moved to Brampton near Huntingdon in Cambridgeshire from locations at Medmenham, Nuneham Park, Wyton and Wembley in 1956 where they were joined by the Joint School of Photographic Interpretation (JSPI) in December.
In 1980 the (UK) was dropped from the name to reflect the closing of the Cyprus-based JARIC (ME), later JARIC(NE) in April 1975. On 19 April 1996 the unit ceased to fall under operational control of the Royal Air Force and became an agency under the operational control of the Director General Intelligence and Geographic Requirements, taking a more centralised government role within the Ministry of Defence.
