RAF Hell's Mouth was commissioned in February 1937 as a Relief Landing Ground, later an Emergency Landing Ground for RAF Penrhos. It took its name from the local coastline which is known as Hell's Mouth due to the 'hellish' conditions for sailors with little shelter from the sea.[1] It was also an air gunnery and bombing range, with targets on the land, floated 1 mile offshore and towed drogues in the air. A small range railway was in use to provide moving targets.[2]

Typical aircraft using the airfield were Bristol Blenheim and Armstrong Whitworth Whitley. In August 1944 a Vickers Wellington was successfully landed by a Polish pilot following an engine failure. Despite the mismatch in size, the aircraft also was able to subsequently take off.[2]

No. 9 (Observers) Advanced Flying Unit RAF was posted here at some point.[3]

Current useEdit

The site was decommissioned in 1945 and returned to agriculture.[3]
