RNAS Anthorn (Also known as HMS Nuthatch)

The airfield was built in February 1918 as a Fleet Air Arm (FAA) airfield. It was abandoned after World War I ended, however the RAF reinstated the airfield at the beginning of World War II as an emergency landing ground for nearby RAF Silloth.

The site was taken over by the Royal Navy in December 1942, and renamed as RNAS Anthorn. It was commissioned in September 1944 as ‘HMS Nuthatch’. The airfield served as No.1 ARDU (Aircraft Receipt and Dispatch Unit), a unit that accepts aircraft from their manufacturers and prepares them for operational use. The last official flight took off from the airfield in November 1957. It was then put on Care and Maintenance, before it closed down in March 1958.

In 1961 the site was chosen to become a NATO VLF transmitting site for communicating with submarines. One of its main functions is to transmit Greenwich Mean Time to the rest of the world. This time signal is heard as ‘pips’ on the radio and is used by everything from train companies to speed cameras. The aerial masts can be seen from miles around, especially at night with their distinctive red lights.

This remains a secure site so please only view from public roads.
