RAF Calshot was a Royal Air Force (RAF) station located on the Calshot peninsula near Southampton Water in Hampshire, England. Established in 1913 as a Royal Naval Air Service (RNAS) air station, it later became part of the RAF upon the service’s formation in 1918.
Key historical points
| Period | Designation | Primary role |
|---|---|---|
| 1913–1918 | RNAS Calshot | Seaplane and flying boat training for the Royal Naval Air Service. |
| 1918–1939 | RAF Calshot | Maritime aviation training, including flying boat conversion and rescue. |
| 1939–1945 | RAF Calshot | Coastal Command operations; notably anti‑U‑boat patrols and aircraft maintenance during World II. |
| 1946–1961 | RAF Calshot | Post‑war training of aircrew for maritime patrol and rescue; also hosted the RAF Marine Craft Unit. |
| 1961 onward | Decommissioned | The site was transferred to civilian use, becoming the Calshot Activities Centre and the site of the Solent Sky Museum. |
Location and facilities
The station occupied a peninsula between the Solent and Southampton Water, providing direct access to sheltered waters ideal for seaplane operations. Facilities included slipways, hangars for flying boats, a seaplane base, and support buildings for crew training and aircraft maintenance.
Notable units and aircraft
- No. 4 Flying Boat Training School (1919–1939) – trained crews on the Felixstowe F.2A and other flying boats.
- No. 422 (General Reconnaissance) Flight – operated during WWII with Short Sunderland flying boats.
- RAF Marine Craft Unit – maintained motor launches and rescue boats for maritime operations.
Post‑military use
After the RAF vacated the site in 1961, the area was redeveloped for recreational and educational purposes. The Calshot Activities Centre uses former RAF buildings for water sports, while the Solent Sky Museum preserves historic aircraft and memorabilia related to British aviation, including items from RAF Calshot.
Legacy
RAF Calshot played a central role in the development of British maritime aviation, particularly in the training of seaplane and flying‑boat crews throughout both World Wars and the early Cold War period. Its conversion to civilian facilities reflects broader post‑war demilitarisation of coastal RAF stations.
