RAF Menwith Hill in the context of Harrogate

⭐ Core Definition: RAF Menwith Hill

Royal Air Force Menwith Hill (RAF Menwith Hill) is a Royal Air Force station near Harrogate, North Yorkshire, England, which provides communications and intelligence support services to the United Kingdom and the United States. The site contains an extensive satellite ground station and is a communications intercept and missile warning site. It has been described as the largest electronic monitoring station in the world.

RAF Menwith Hill is owned by the Ministry of Defence (MoD), but made available to the US Department of Defense (DoD) under the NATO Status of Forces Agreement 1951 and other, undisclosed agreements between the US and British governments. His Majesty's Government (HMG) is entitled to possession of the site and retains control over its use and its facilities, though the administration of the base is the responsibility of the US authorities, with support provided by around 400 staff from Government Communications Headquarters (GCHQ), in addition to United States Air Force (USAF) and US National Security Agency (NSA) personnel. In 2014, the number of American personnel was reduced as part of a streamlining of operations due to improvements in technology.

RAF Menwith Hill in the context of Signals intelligence

Signals intelligence (SIGINT) is the act and field of intelligence-gathering by interception of signals, whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). As classified and sensitive information is usually encrypted, signals intelligence may necessarily involve cryptanalysis (to decipher the messages). Traffic analysis—the study of who is signaling to whom and in what quantity—is also used to integrate information, and it may complement cryptanalysis.
