Benbradagh (from Irish Binn Bhradach 'treacherous peak')[2] is a large hill near Dungiven in County Londonderry, Northern Ireland.

[1] Benbradagh was used from the 1940s to the early 1970s as a United States Military communications base for its North Atlantic fleet.

US forces also built underground stores for high explosives at Benbradagh.

In the early 1980s, Col Buckley, of the Directorate of Military Intelligence (Ireland), believed the UK could use the facility to store nuclear weapons.
