**RNAS Capel** (later **RAF Folkestone**) was a [First World War](/source/World_War_I) airship station operated by the [Royal Naval Air Service](/source/Royal_Naval_Air_Service) near [Folkestone, Kent](/source/Folkestone%2C_Kent), England.[1]

## History

When Germany declared in February 1915 that it would commence unrestricted submarine warfare, the Royal Navy responded with the building of airship stations around the coast.[1] Being close to the Dover Straits the open fields east of [Capel-le-Ferne](/source/Capel-le-Ferne) were seen as ideal location for a base and work began in April 1915.[1] Although not entirely completed, the base was officially opened on 8 May 1915, under the command of Lt. A.D. Cunningham.[1] The first airship for Capel was to have been SS-1 the first of a new [sea scout class](/source/SS_class_blimp) of non-rigid airships, on delivery to Capel from [RNAS Kingsnorth](/source/RNAS_Kingsnorth) on 7 May it hit telegraph wires and was destroyed. Despite the accident, more sea scouts were soon delivered to Capel.

## Airship production

SSZ-37 a type designed at Capel

Following the successful repair to SS-10 at Capel production of the airships moved from Kingsnorth to Capel, although by 1916 production had moved again to Vickers at Barrow and RNAS Wormwood Scrubs.[1] The engineering section at Capel went on to design an improved variant of the SS airship, which would be known as the [SSZ](/source/SSZ_class_blimp).[1] The SSZ had an improved aluminium covered ash-framed car and was fitted with a 75 hp [Rolls-Royce Hawk](/source/Rolls-Royce_Hawk) aero-engine, it was fitted with a 70,000 cu ft (2,000 m3) envelope and test flown in August 1916.[1] When the Admiralty were informed about the new airship they censured the air station for carrying out unauthorised modifications, but on the other hand ordered the type into production.[1]

## Operations

The airships carried out patrols along the English coast, and escorted shipping across the channel as a lookout for submarines.[1] In April 1918, the Royal Air Force was formed and Capel became RAF Folkestone. By then it had three large airship sheds and a grass landing area.[1] On 16 September 1918, while under the command of a [United States Navy](/source/United_States_Navy) officer, SSZ.1 [depth-charged](/source/Depth_charge) and sank submarine [UB-103](/source/SM_UB-103).[1]

Two sub-stations were used: at [Godmersham Park](/source/Godmersham_Park) north of [Wye](/source/Wye%2C_Kent), and [Wittersham](/source/Wittersham) south of [Tenterden](/source/Tenterden). The sites were used as mooring-out bases where airships could be secured in a sheltered area.[1]

## Closure

Following the end of the First World War, the station closed during the summer of 1919. In the [Second World War](/source/World_War_II) the site was used as a [radio monitoring station](/source/Y-stations).[1]
