Although RAF stations are usually associated with aircraft, RAF Fylingdales was established for a different purpose. It became operational in September 1963 as part of a network designed to provide early warning of ballistic missile attacks. Despite the seeming lack of observable military activity, this particular station has always attracted a constant wave of sightseers eager to snap photos of its listening devices, even after transitioning away from the traditional ‘golf ball’ design in the early 1990s.

                                 

                                         

RAF Fylingdales located on the North Yorkshire Moors around 10 miles south of Whitby, is synonymous with the Cold War. It is essentially a giant monitoring device providing a 24/7 service to Britain and its allies, warning of any missiles launched towards the West. Declared operational in September 1963, the station initially comprised three radomes. These giant ‘golf ball’ structures allowed NATO to eavesdrop on the Soviet Union, providing the country and its allies with an ominous four-minute warning ahead of any attack.

The station’s motto is, perhaps unsurprisingly, Vigilamus, which translates from Latin as “we are watching” or “we are awake”. The Fylingdales unit badge consists of the White Rose of Yorkshire and a flaming torch, representing its role as a sentry against any sudden surprise attack.

Remembered by those of a certain age for its much-loved yet eerily ominous radomes, the original structures were eventually replaced by a Solid-State Phased Array Radar (S-SPAR). Dubbed by some as the ‘giant toaster’, this new device was declared operational in 1992 and is capable of detecting an item the size of a drinks can 3,000 miles into space.

Thirty years before the arrival of the S-SPAR, Fylingdales’ three original listening devices were constructed to form one part of a triumvirate of centres making up the Ballistic Missile Early Warning System (BMEWS). The station went online around the same time as Thule in Greenland and Clear in Alaska. It quickly became a slightly macabre tourist attraction, considering its role in predicting the near-certain deaths of millions of people across the globe.ce

Initial plans were to site Fylingdales on a cliffside a few miles north. However, concerns about a potential attack from enemy craft operating off the coast saw it moved inland. The site retained the Fylingdales name but was built instead at Snod Hill—a choice likely driven by a limited desire to call the base RAF Snod!

Snod Hill was originally a wartime mortar range and a post-WWII munitions dump. The RAF Bomb Disposal unit cleared the site before construction work began in 1960 as a joint operation between Britain and the US. The Radio Corporation of America (RCA) developed the site, and RCA (Great Britain) maintained it.

The three original radomes each housed an 84-foot-diameter parabolic dish antenna. The protective shells surrounding them were made up of more than 1,600 individual panels around six inches thick. This gave them their giant ‘golf ball’ appearance and prevented both the enemy and the public from seeing where they were pointed.

Two of the radomes tracked side to side, with the first detecting targets at an elevation of 2.5 degrees above the horizontal, and the second at 5 degrees above the horizontal to catch a missile reaching its boost phase. The third radome would then track the missile, calculating its trajectory and determining its potential impact point. While most people were unaware of the exact nature of the work at Fylingdales, it soon became a must-see attraction for those holidaying on the North Yorkshire coast.

However, security at this strategically important site was tight during the 1960s. Armed personnel routinely moved on any motorists who parked near the base for any prolonged period.

In the late 1980s, work began to upgrade the station's listening capabilities. The three radomes were replaced by the S-SPAR tetrahedron (pyramid) structure, a 120-foot (37-metre) high radar built by the US defence contractor Raytheon.

Since becoming operational in 1963, RAF Fylingdales has played an important role in missile warning for the United Kingdom and United States. Its work has also included tracking satellites and space debris, connecting its Cold War origins with the development of military space surveillance. Behind that work has been a longstanding partnership between RAF personnel, American counterparts and the civilian specialists supporting the station’s radar systems.
