RNAS St Merryn

RNAS St Merryn was a Royal Naval Air Station near St Merryn, Cornwall, commissioned as HMS Vulture during the Second World War. The station served as a land-based training and operational base for the Fleet Air Arm, hosting a range of squadrons and aircraft types engaged in pilot training, anti-submarine patrols, and deck-landing practice. The airfield's coastal location placed it among other notable Cornwall aviation and military sites, supporting wartime maritime operations in the Atlantic Ocean and the English Channel.

History

The site was requisitioned following the outbreak of World War II and development was overseen by the Admiralty in coordination with local authorities in Cornwall and the Civil Aviation Authority. Commissioned as HMS Vulture, the base opened to accommodate expanding Fleet Air Arm requirements after losses in the Battle of the Atlantic and the need to train aircrew for operations related to the Royal Navy and Western Approaches Command. During wartime, the station interacted with nearby RAF stations such as RAF Predannack and RAF St Eval while supporting escort carriers and Royal Navy aircraft carrier operations operating from Portsmouth and Plymouth. Postwar reductions in force and the 1940s–1950s reorganisation of United Kingdom military aviation led to gradual drawdown, culminating in decommissioning as an active naval air station in the mid-1950s as the Royal Air Force and Fleet Air Arm rationalised airfields.

Layout and Facilities

The airfield featured multiple concrete runways, hangars, technical accommodation, and dispersed hard standings typical of wartime Royal Navy shore establishments. Air traffic and maintenance were coordinated from a control tower sited alongside fuel storage and armament sheds, echoing layouts at contemporaneous bases such as HMS Daedalus and HMS Sparrowhawk. Resident barrack blocks, medical facilities, and a sick quarters serviced personnel drawn from Royal Navy ratings, Royal Naval Volunteer Reserve aircrew, and attached technical trades from Fleet Air Arm Training School elements. Proximity to the Cornish coast allowed use of nearby beaches and cliffs for navigational exercises and provided access to overwater training ranges used by units rotating through from RNAS Lee-on-Solent and HMS Seahawk.

Operations and Units

Throughout its operational life the station hosted a succession of Fleet Air Arm squadrons, operational training units, and conversion flights. Squadrons deployed to the station included carrier training and anti-submarine warfare detachments drawn from numbered FAA squadrons, with personnel transfers common between HMS Argus-based flights and unit rotations returning from Mediterranean Sea deployments and the North Atlantic convoy theatre. The base provided deck-landing training for aircrew destined for service aboard Illustrious-class and Implacable-class carriers, supporting pilots who would serve in campaigns such as the Norwegian Campaign and operations in the English Channel. The station also hosted maintenance flights from Royal Naval Air Service-era reserve units and collaborated with Admiralty experimental and trials establishments on armament and airframe modifications.

Aircraft and Equipment

Aircraft types operating from the field ranged from early-war biplanes to later monoplane fighters and anti-submarine aircraft. Examples included carrier-capable types and training variants similar to the Fairey Swordfish, Supermarine Seafire, and Fairey Barracuda used across the Fleet Air Arm inventory, alongside multi-role aircraft like variants of the Avro Anson for navigational training. Engine and airframe servicing facilities supported Rolls-Royce and Bristol powerplants common to FAA types, while ordnance stores handled bombs, depth charges, and machine gun/60 lb rocket fittings as used in anti-submarine warfare and deck-attack training. Ground equipment included recovery cranes for airframe salvage, aviation fuel bowsers, and instrument landing aids comparable to systems installed at RNAS Yeovilton and RNAS Culdrose.

Postwar Use and Legacy

After decommissioning, the site entered a period of civilian reuse, with portions converted to agricultural use, industrial units, and limited civil aviation activity reflecting patterns seen at other former wartime airfields across England. Surviving structures, including perimeter tracks and hangar foundations, became focal points for local heritage groups and aviation historians documenting Second World War naval aviation. The station's contribution to Fleet Air Arm training and coastal defence has been commemorated in regional archives and local museums alongside exhibits covering Cornwall wartime history, the Royal Navy, and naval aviation pioneers. Its legacy continues through veteran associations connected to squadrons that served there and through ongoing research by enthusiasts associated with organisations such as the Imperial War Museums and regional historical societies.
