Airfield
RAF Northolt in West London is one of the oldest RAF stations in Britain and one of the most operationally enduring, having served continuously from its establishment in 1915 through both world wars, the Cold War, and into the present day. During the Battle of Britain it was a frontline Fighter Command station credited with 14 destroyed enemy aircraft in a single day. Today it serves as a base for VIP and government transport flights, military training, and is the second-busiest airport in the London area after Heathrow.
R AF Northolt's history stretches back to 1915, when the Royal Flying Corps established an airfield on common land in West London to serve as a training and home defence base during the First World War. After the RFC merged into the Royal Air Force in 1918, Northolt was retained as a permanent station and gradually developed as one of London's primary military airfields.
Between the wars, Northolt was used for various roles including squadron training, experimental work, and as a base for the Prince of Wales and royal flights. The station was modernised and expanded in the late 1930s in preparation for the coming conflict, receiving the new Hawker Hurricane and Supermarine Spitfire as Fighter Command prepared to meet the Luftwaffe.
During the Battle of Britain in 1940, No. 1 Squadron RAF — one of the oldest and most distinguished squadrons in the RAF — operated from Northolt, famously engaging Luftwaffe formations on 18 August 1940 in some of the most intense fighting of the campaign. In a single day's action, the squadron was credited with destroying 14 enemy aircraft, contributing significantly to the defence of London. The intensity of operations at Northolt made it a priority target for the Luftwaffe, and the station was subjected to regular bombing raids throughout the Battle of Britain.
The station's wartime history extended beyond the Battle of Britain. During the Allied invasion of Normandy in 1944, Northolt served as a key base for fighter sweeps and armed reconnaissance over the invasion beaches and northern France. In the immediate post-war period, the station was used for transport operations, part of the Berlin Airlift, and as a base for the RAF's rapid deployment capabilities.
In the latter half of the 20th century, Northolt transitioned to serving as the primary RAF base for VIP and government transport, a role that brought it into regular use for high-level state flights, royal travel, and diplomatic missions. This role continues today, with the station operating alongside civilian London Heathrow and RAF Northolt handling a significant volume of military and government flying alongside its civilian partners.

RAF Northolt remains an active military airfield with a remarkable degree of continuity — the station has been in continuous military aviation use since 1915, making it one of the oldest actively operated military aerodromes in the world. The original 1930s runway infrastructure has been maintained and upgraded, with the current runway (originally built in the late 1930s and extended post-war) still in use for both military fast jets and government transport aircraft.
Many of the original wartime buildings survive, including the station's iconic control tower — one of the few surviving examples of a pre-war RAF operations building still in active use. The original hangars from the Fighter Command era have been maintained and incorporated into current operations. The dispersal pans and taxiway network from the Battle of Britain period retain much of their original geometry, though surfaces have been upgraded.
Of particular historical significance are the surviving wartime sector operations facilities, which directed the Battle of Britain squadrons from Northolt. These form part of the station's contribution to the RAF's historic command infrastructure. The proximity of the station to West London — having literally been swallowed by the city's urban expansion — means that Northolt sits in a remarkable position as an enclave of military aviation surrounded by suburban development.
As the RAF's primary London base for VIP and government transport, the station regularly hosts aircraft including the Royal Flight, Voyager aircraft for government ministers, and training flights. The blend of heritage infrastructure and active military operations gives Northolt a unique character among British military airfields.
The main runway at RAF Northolt is approximately 1,688 metres (5,538 ft) in length, oriented 07/25. This is a substantial runway for a station of its type, built to accommodate a wide range of aircraft from wartime fighters to modern military transport. The runway was originally constructed in the late 1930s as part of the Fighter Command expansion programme and has been maintained and resurfaced continuously since then. Its length was sufficient to accommodate fully-armed Hurricane and Spitfire fighters during the Battle of Britain, and it has been upgraded to handle heavier aircraft including jets and transport aircraft post-war.
The taxiway network retains much of its original wartime dispersal layout, with hardstandings arranged around the perimeter taxiway allowing aircraft to be dispersed away from the main runway to reduce their vulnerability to attack — a principle that was tested repeatedly during the Battle of Britain bombing raids on Northolt. The original 1930s hangars remain in active use, their steel frames and high roofs designed for the maintenance of biplane and early monoplane fighters, now serving a broader range of aircraft types.
