Defence Intelligence (DI) is an integral part of the Ministry of Defence (MOD) and the main provider of strategic defence intelligence to the department and the armed forces.
DI provides timely intelligence products, assessments and advice to guide decisions on policy and the commitment and employment of the armed forces; to inform defence research and equipment programmes; and to support military operations.
DI is an essential element of the UK’s central intelligence machinery (along with the Government Communications Headquarters (GCHQ), the Secret Intelligence Service (SIS) and the Security Service) contributing staff and resources to the Cabinet Office in support of the Joint Intelligence Committee (JIC), the UK’s national intelligence committee, and also to the Joint Terrorism Analysis Centre (JTAC).
DI supports other government departments with advice and intelligence assessments. Its assessments also support intelligence analysis and operations undertaken by NATO and the EU.
DI staff are located at sites in Central London as well as at Feltham, Chicksands, RAF Wyton and RAF Northolt where they are an integral part of the local communities.
