RAF Boulmer in Northumberland is a critical component of the RAF Battlespace Management Force and home to the Air Surveillance and Control System (ASACS).
The Control and Reporting Centre (CRC) at RAF Boulmer uses ground-based military and civilian radars to monitor, detect and identify all aircraft in and around UK airspace - 24/7, 365 days a year. This is called the Recognised Air Picture (RAP). The Quick Reaction Alert Typhoons at RAF Lossiemouth and RAF Coningsby can be scrambled to intercept unidentified aircraft.
RAF Boulmer is also home to the ASACS Operational Conversion Unit (OCU), a worldwide centre of excellence on leading-edge battlespace management training and education for the UK Armed Forces, NATO and other foreign national military personnel.
Around 1,000 Service, civilian and contracted personnel work at RAF Boulmer.
