Airfield
RAF Biggin Hill in Kent is one of the most famous fighter stations in RAF history. During the Battle of Britain in 1940, it was one of the three most heavily engaged airfields in Fighter Command's 10 Group, hosting No. 72 Squadron and No. 32 Squadron among others, and earning a reputation as one of the Luftwaffe's most targeted sites. The airfield was fortified with the legendary Hawker Hurricane and Supermarine Spitfire, and its underground operations room — still surviving — directed thousands of interceptions against German raiders.
R AF Biggin Hill's aviation history dates back to the early 1900s when it was used as a base for early aviation pioneers. The Royal Flying Corps established a station there in 1916, and after the First World War it became a civil aerodrome before being reactivated in the 1930s as the threat from Nazi Germany became undeniable. By 1938, the airfield had been rebuilt and re-equipped as a Fighter Command station, and its proximity to London made it strategically vital.
During the Battle of Britain in the summer and autumn of 1940, Biggin Hill was at the very centre of Britain's air defence. As part of Fighter Command's No. 10 Group, the station fielded multiple Spitfire and Hurricane squadrons in almost constant action against the Luftwaffe's efforts to achieve air superiority over Southeast England and London. The airfield was subjected to heavy bombardment — the Luftwaffe recognised that destroying Biggin Hill would severely degrade the RAF's ability to defend the capital. The attacks were so persistent that the station earned the nickname "The Hill of Hell." Despite the bombing, operations continued almost without interruption, a testament to the determination of ground crew and the resilience of the hardened underground sector operations room.
The underground operations room at Biggin Hill — a massive bunker built into the chalk hillside — was the nerve centre of the station's air defence. From here, controllers coordinated squadron scrambles, tracked incoming raids using radar and observer reports, and directed fighters into combat. The operations room could accommodate hundreds of personnel and was equipped with the plotting tables and communication systems of the era. Its survival through the Battle of Britain and the subsequent decades makes it one of the most important tangible heritage assets of any RAF station.
Following the Battle of Britain, Biggin Hill continued as an active RAF station through the Cold War, operating progressively from fighter aircraft to more modern jets, and eventually to serving as a base for communications and training aircraft. As London's urban expansion reached Kent, the station's operational future became increasingly constrained, and RAF Biggin Hill closed as an active military airfield in the early 2000s. Today, the site operates as Biggin Hill Airport — a civilian aerodrome with significant heritage status — and the underground operations room is preserved and open to the public.

The most significant surviving feature at Biggin Hill is the underground Sector Operations Room, carved into the chalk hillside on the eastern side of the airfield. This bunker — with its multiple levels, communications rooms, and plotting chamber — is one of the finest surviving examples of RAF WWII command infrastructure. It has been preserved and opened to the public as a heritage site, giving visitors an extraordinary window into how the Battle of Britain was directed in real time. The room's original equipment, plotting boards, and communications arrays are still in place, providing an almost complete picture of 1940s air defence operations.
The airfield surface has been partially preserved. The runways and taxiways of the former RAF station are still clearly visible, and the overall airfield layout — including the original fighter dispersal pans, taxiways, and hardstandings — retains much of its 1940s geometry. Some of the original wartime hangars have survived and are used by the current civilian airport operations. The control tower, though modified for civilian use, is still standing and is a landmark feature of the site.
As Biggin Hill Airport, the site continues to serve aviation, with private aircraft, flight schools, and corporate aviation operations using the runways. However, the heritage buildings — the operations room entrance, the original station buildings, the surviving hangars — create a layered landscape where the civilian present coexists with the military past. Memorials to the Battle of Britain and the squadrons that served there are installed around the site, making Biggin Hill one of the most visited heritage aviation sites in the United Kingdom.
The original RAF Biggin Hill had two runways: a main strip of approximately 1,280 metres (4,200 ft) oriented east-west, and a shorter crosswind runway. These grass and tarmac runways were adequate for the fighter aircraft of the era — Hurricanes and Spitfires — which required relatively short take-off and landing distances compared to the heavy bombers that operated from other station types. The runways were supplemented by a network of dispersal hardstandings located around the perimeter, designed to spread aircraft out and reduce their vulnerability to bombing attacks — a layout that can still be traced in the surviving airfield geometry today.
Following the closure of RAF operations, the airfield was converted to civilian use and the runway was extended to approximately 1,782 metres (5,847 ft), allowing the site to accommodate a wider range of general aviation aircraft. The current runway retains the general alignment of the original main strip. The old wartime dispersal pans and taxiway network, many of which have been preserved, form the current airport aprons and hangars, creating a landscape where the physical memory of the Battle of Britain is encoded into the current civilian aviation infrastructure.
