19 Squadron on 1 April 2021,[37] and continues to operate the Control and Reporting Centre from RAF Boulmer in Northumberland.

This combination of radar; fighters; anti-aircraft guns; and the operations rooms that tied them all together was credited with ultimate success during the Battle of Britain.
