No. 11 Group. It is a Royal Air Force group, most famously operational during the Second World War as a key component of RAF Fighter Command. Throughout its history, it has been primarily responsible for the air defence of London and South East England. The group played a decisive role during the Battle of Britain and has been reformed multiple times in the post-war era to meet evolving air defence needs.

History

The group was first established on 1 April 1918, within the framework of the newly independent Royal Air Force, following the amalgamation of the Royal Flying Corps and the Royal Naval Air Service. Its initial formation was short-lived, as it was disbanded in 1923 during the inter-war period's military reductions. The group was reformed on 1 May 1936 as part of the expansion of RAF Fighter Command, a direct response to the growing threat from Nazi Germany under Adolf Hitler. This reformation placed it under the overall command of Hugh Dowding, who was instrumental in developing the Dowding system of integrated air defence.

Second World War

During the Second World War, the group became the epicentre of British fighter operations, particularly throughout the pivotal Battle of Britain in 1940. Under the command of Keith Park, it bore the brunt of the Luftwaffe's attacks, coordinating squadrons from vital sector airfields like RAF Biggin Hill, RAF Hornchurch, and RAF Kenley. The group's operations were integral to the success of the Dowding system, which utilized Chain Home radar stations and the Observer Corps. Following the battle, it participated in offensive sweeps over Occupied France, such as Circus operations, and provided crucial air cover for the Dieppe Raid and the Normandy landings during Operation Overlord.

Post-war era

After the war, the group continued its air defence role within RAF Fighter Command during the Cold War, transitioning to jet aircraft like the Gloster Meteor and later the English Electric Lightning. It was disbanded in 1961, only to be almost immediately reformed that same year within RAF Strike Command to control tactical fighter forces. This iteration was short-lived, disbanding again in 1963. The group was resurrected in 1968 as part of UK Air Defence Region, controlling all United Kingdom based fighter squadrons until its final disbandment in 1996. It was briefly revived between 2000 and 2006 to oversee RAF training and support helicopter forces.

Air Officers Commanding

Notable commanders have included several distinguished Royal Air Force officers. During its most critical period, Air Vice-Marshal Keith Park led the group through the Battle of Britain. He was succeeded by Air Vice-Marshal Trafford Leigh-Mallory, who later commanded the Allied Expeditionary Air Force. Post-war commanders included Air Vice-Marshal Johnnie Johnson, the RAF's top Allied fighter ace, and Air Vice-Marshal Peter Squire, who later served as Chief of the Air Staff.

Notable personnel

Many renowned individuals served within its squadrons. Fighter aces such as Douglas Bader, who flew with No. 242 Squadron RAF despite his disability, and Sailor Malan of No. 74 Squadron RAF were key figures. Johnnie Johnson scored many of his victories while serving with units under its control. Other notable figures include Robert Stanford Tuck, a high-scoring ace, and Richard Hillary, author of The Last Enemy, who flew with No. 603 Squadron RAF.

Bases

Its headquarters was famously located in the underground Battle of Britain Bunker at RAF Uxbridge, which housed the group's operational control room. Key sector stations during the Battle of Britain included RAF Tangmere, RAF Middle Wallop, and RAF Debden. In the post-war period, it also operated from stations like RAF Bentley Priory (the headquarters of RAF Fighter Command), RAF West Malling, and, during its later incarnations, RAF Boulmer and RAF Neatishead.
