RAF Acklington sat on open Northumberland farmland a little way inland from the coast, close enough to smell the sea on the wrong wind and near enough to the convoy routes to make its purpose obvious. On paper it began as “Southfields”, a First World War landing ground. In practice it became something broader: a Fighter Command station that alternated between sharp moments of activity and long stretches of watchfulness, then a post-war training and support base that lasted into the 1970s, before opencast mining and prison walls erased most of what had been built.
What makes RAF Acklington worth attention is that it shows how an airfield could be repeatedly repurposed without ever becoming famous. It was rarely glamorous. It was often busy. And, as with many northern stations, its story ends not with a ceremony but with the landscape being physically rearranged.
Southfields and the early habit of “somewhere to put the aeroplanes”
Acklington’s first life was as a simple landing ground used for home defence during the First World War. It was taken up in late 1916 and used by No. 36 Squadron for night landing and local defence work, with the sort of modest dimensions you would expect of a field adapted in a hurry. It served through to the end of the war period and then slipped back into peacetime quiet.
That pattern, a wartime need followed by neglect, mattered later. When the Air Ministry began building and re-opening airfields in the late 1930s, a remembered patch of level ground could suddenly become a “site” again.
Reopening in 1938: training first, then the war arrives
Acklington reopened on 1 April 1938, not as a front-line fighter base but under Training Command. In its first months it hosted specialist training and armament work, and by the time war broke out it had already been through one of those quick pre-war transformations that turned fields into stations: hangars, buildings, stores, a proper administrative shape.
Then September 1939 changed the priorities. The training units moved, and RAF Acklington was transferred to Fighter Command as part of the northern air-defence system. It became a working fighter station, one that could take squadrons shifting around the country, bolster the defence of the North-East, and provide a ready base near the approaches to Tyneside, the Tyne and the Forth convoy routes.
In the summer of 1940 RAF Acklington is often described as a “rest” or reinforcement station within the wider Battle of Britain picture. That phrase can mislead. “Rest” did not mean silence. It meant squadrons arriving tired, refitting, flying patrols, scrambling for unidentified aircraft, and doing the routine flying that wears airframes and men down just as surely as headline battles.
From day fighters to night fighters
By 1941 the character of the work began to shift. The threat was not only daylight raiders but night intrusion, and the RAF’s response was to develop night fighting properly rather than improvised. From May 1941, Bristol Beaufighter night fighters were based at Acklington, part of the counter to nocturnal raids and a sign that the station was now plugged into the growing radar-led, night-interception system.
This is where Acklington’s international cast becomes clear. Canadian squadrons operating in Fighter Command’s night-fighter role passed through, and contemporary photographs show Beaufighters and crews based at the station. It is a small reminder that the “home front” air war was never solely British in manpower, even when it was being fought over British fields and coastline.
For much of the later war, Acklington’s work settled into a mixture of convoy patrols, night-fighter duties, aircraft conversion and the constant coming-and-going of units. A range of types operated from the airfield as requirements changed, including Defiants, Havocs, Typhoons and Mustangs. The names can read like a list, but they point to a practical reality: Acklington was a station that could absorb change without fuss.
The 1944 rebuild: hard runways for a different kind of RAF
In 1944 the airfield was upgraded in a way that physically altered it. Work created three paved runways and an improved perimeter track, the classic “A” pattern layout of many wartime expansions, along with dispersals and additional hangarage. The timing matters. By then Allied air power was being concentrated for operations on the Continent, and the northern airfields were being reshaped to support training, movement and flexible use rather than the frantic expansion of 1940.
Late in the war Acklington hosted operational training work, including a brief period in 1945 when Typhoons were flown in that role. After that came another change in atmosphere: the return of front-line squadrons with Mosquitoes and early jets. For a station that had begun with grass and biplane-era habits, that was a long way travelled.
Post-war: targets, jets, training and helicopters
After 1945, Acklington did what many RAF stations did: it stayed open by becoming useful in the less-photographed business of keeping the force sharp.
An Armament Practice Station became established from 1946, running air-to-air firing and associated work for visiting squadrons. That phase lasted into the mid-1950s. In 1956 the station shifted again, becoming a mixed jet fighter and search-and-rescue helicopter base. It hosted front-line jets and, later, training units. No. 6 Flying Training School became resident in the early 1960s and remained for several years, while helicopter units continued flying after the fixed-wing rhythm had faded.
There is a particular northern texture to the search-and-rescue story. The North Sea is not forgiving, and the practical value of SAR detachments based close to the coast was obvious to anyone who watched the weather come in. Helicopters continued operating from Acklington into the 1970s.
Closure and the afterlife: prisons, mining, fragments
By the late 1960s the station’s future was being discussed in Parliament, with the Ministry of Defence stating that closure had been decided after examining possible alternative uses. Plans for non-flying use followed. In the 1970s, the runways were lifted and the landing ground was effectively destroyed by opencast mining. What remained was not an airfield waiting for re-use, but a landscape that had been physically consumed.
A prison complex grew into the site, later including HMP Acklington and Castington, and then merging into HMP Northumberland. Some station buildings survived because they were convenient to reuse. Much else vanished because the ground itself was worked.
If you visit the area now, “RAF Acklington” is something you reconstruct from perimeter-track traces, surviving structures in use, local memory, and the occasional object saved from demolition. There is also an explicit act of remembrance: a memorial plaque in a nearby church honouring aircrew who served at Acklington and died in local crashes, a quiet counterweight to the way the airfield’s fabric was stripped away.
Acklington’s story, then, is not a single celebrated episode. It is an account of British air power doing its steady work in the north, adapting to changing threats and aircraft, and then being overtaken by post-war economics and land use. The aerodrome did not simply close. It was dismantled, mined, and rebuilt into something else. That, in its own way, is as revealing as any dramatic combat narrative.
