It explores how radar stations, Royal Observer Corps posts, and operations rooms worked together to detect and respond to incoming enemy aircraft.Moving beyond the well-known events of the Battle of Britain, the book traces the evolution of Scotland’s air defence network throughout the war, highlighting advances in technology and tactics. For the first time, it also incorporates the role of Gun Operations Rooms under Anti-Aircraft Command into the broader narrative.Detailed accounts of each operations centre and a full listing of Royal Observer Corps posts across Scotland allow for local-level research into the contributions of individual communities. Drawing on first-hand testimonies and rare wartime photographs – many never published before – this book offers valuable insights for aviation, military, and local historians, and for anyone interested in Scotland’s wartime experience.
