RAF Bishopscourt

Military drawdown and strategic realignment following the end of the Cold War. As a key radar station designed to provide early warning against Soviet threats, its primary mission became redundant with the dissolution of the Warsaw Pact. The closure was part of the UK's 'Peace Dividend' defence cuts.

The site has been extensively redeveloped and is now used for multiple purposes. The most prominent use is the Bishopscourt Racing Circuit, a major motorsport venue that utilizes the former runways and perimeter tracks for car and motorcycle racing. Parts of the site have been converted into the Bishopscourt Industrial Estate, housing various commercial and industrial businesses in the former military buildings. Additionally, a large portion of the airfield has been developed into a solar farm. The iconic radome still stands as a landmark but is no longer operational for military or civilian air traffic control purposes.

RAF Bishopscourt was initially opened in 1941 during World War II as a satellite airfield for RAF Downpatrick. It primarily served as a training facility, hosting units like the No. 7 Air Gunnery School. Its most significant role came during the Cold War. In the 1950s, it was redeveloped into a major Control and Reporting Centre (CRC) and a key radar station in the UK's air defence network. It was equipped with powerful early-warning and height-finding radars, housed within a distinctive large white dome, or 'radome', which became a local landmark known as 'the golf ball'. The station's mission was to detect and track potentially hostile aircraft, primarily Soviet bombers, and to coordinate RAF fighter interceptions over the Atlantic and the Irish Sea.

There are no known plans or prospects for reopening RAF Bishopscourt as an active airfield. The site's infrastructure has been fundamentally altered for its current uses, including the construction of a permanent motorsport circuit, an industrial park, and a solar farm. Reverting the site to aviation use would be prohibitively expensive and would require the removal of significant existing commercial and energy infrastructure. Its original military purpose is obsolete, and there is no identified need for a new civilian airport in the immediate area.
