Used	1939–1959
Occupants	Royal Air Force Coastal Command

RAF St Eval was a Royal Air Force station on the north Cornwall coast that operated as a coastal patrol and anti-submarine base during the Second World War and early Cold War era. It supported long-range maritime reconnaissance, convoy escort, and air-sea rescue operations, contributing to Atlantic defence and anti-U-boat campaigns alongside other RAF Coastal Command bases. The station's strategic location near the Celtic Sea enabled interactions with Allied naval forces and aircraft from across Europe and the Atlantic theatre.

History

St Eval opened in 1939 to serve RAF Coastal Command requirements and expand Britain’s maritime patrol network as the Second World War escalated. During the Battle of the Atlantic, it worked in concert with bases such as RAF Pembroke Dock, RAF Sullom Voe, RAF Ballykelly, and RAF Limavady to counter the Kriegsmarine submarine threat and protect transatlantic convoys escorted by elements of the Royal Navy and United States Navy. The station experienced German aerial attacks during the Blitz period and was part of broader defensive and offensive operations coordinated with commands in RAF Bomber Command and Royal Navy Fleet Air Arm units. Post-1945, St Eval adapted to Cold War maritime surveillance demands, supporting NATO-era patrols and cooperating with allied commands such as SHAPE until downsizing and closure decisions linked to defence rationalisation in the 1950s.

Operations and Units

St Eval hosted squadrons from RAF Coastal Command including storied units like No. 53 Squadron RAF, No. 224 Squadron RAF, No. 201 Squadron RAF, No. 217 Squadron RAF, and No. 120 Squadron RAF. These squadrons flew patrols against U-boat wolfpacks and escorted convoys bound for ports like Liverpool, Greenock, Falmouth, and Plymouth. The station worked closely with RAF Transport Command detachments and elements of Air Sea Rescue units, coordinating with Royal Navy escort vessels, HMS Ark Royal, and Convoy HX series operations. Training and maintenance units such as RAF Flying Training Command and depot detachments provided logistic support; liaison occurred with Coastal Command Development Unit and allied squadrons from the Royal Australian Air Force and Royal New Zealand Air Force.

Infrastructure and Architecture

Construction at St Eval involved runways, hangars, control facilities, technical sites, and accommodation dispersed to reduce vulnerability to attack, reflecting design principles used at bases like RAF Scampton and RAF Leconfield. Structures included Type-C hangars, hardened dispersal pens, and a control tower with visual and radio-navigation equipment paralleling installations at RAF Benson and RAF Lossiemouth. The base incorporated fuel storage, bomb disposal areas, and maintenance workshops similar to those at RAF Harwell and RAF Mildenhall. Defensive features and perimeter works owed design influences from pre-war Air Ministry standards and wartime adaptations seen elsewhere across Royal Air Force infrastructure.

Aircraft and Equipment

Aircraft types operated from the station ranged from flying boats to landplanes: long-range patrol types such as the Consolidated PBY Catalina, Short Sunderland, Lockheed Hudson, Armstrong Whitworth Whitley, Avro Lancaster adapted for maritime roles, Handley Page Halifax variants, Vickers Wellington, and later Avro Lincoln and Boeing B-17 Flying Fortress detachments in special operations. Anti-submarine armament and sensor fitments included depth charges, airborne radar sets like ASV radar installations, Leigh Lights for night interceptions, and radio direction-finding equipment comparable to wartime innovations at Bletchley Park-linked signals facilities. Ground support equipment comprised tugs, fuel bowsers, bomb trolleys, and workshop tools parallel to those at RAF Waddington.

Accidents and Incidents

The tempo of maritime patrols and wartime operations produced accidents and operational losses involving aircraft from squadrons stationed at St Eval, some resulting from enemy action, weather over the Irish Sea and Celtic Sea, or navigational error. Notable incidents included crashes during anti-submarine sorties, forced ditchings, and collisions during foggy approaches similar to events recorded at RAF Coastal Command stations such as RAF Thornaby and RAF Calshot. Casualties involved aircrew drawn from the Royal Air Force Volunteer Reserve, Royal Canadian Air Force, Royal Australian Air Force, and Royal New Zealand Air Force who served on exchange or attachment. Crash investigations invoked procedures maintained by the Air Ministry and influenced subsequent safety, training, and search-and-rescue doctrine adopted by Air Sea Rescue services.

Post-war Use and Preservation

Following decommissioning, parts of the site passed to civil authorities and private owners, with some technical areas repurposed for agriculture and industrial use, mirroring conversions at former stations like RAF Hemswell and RAF Upottery. Heritage groups and local historians from Cornwall and organisations such as the Imperial War Museum and regional archives documented the station’s wartime role, salvaging artefacts and maintaining memorials to aircrew who perished. Debates over redevelopment balanced economic interests with conservation of aviation archaeology similar to discussions around Duxford Airfield and Orfordness; remnants of runways, hangars, and dispersal areas remain visible in landscape surveys and aerial photography used in studies by heritage organisations.
