This infographic illustrates the Dowding System, Britain’s groundbreaking air defense network that played a critical role in winning the Battle of Britain during World War II. Designed by Air Chief Marshal Hugh Dowding (1882–1970), it was the world’s first fully integrated air defense system, combining radar detection, communication lines, and centralized command to create a coordinated national shield against German air raids.

At the heart of the system were radar stations, notably the Chain Home network, which provided early warnings of incoming enemy aircraft. These signals were funneled through filter rooms to strip out false positives, then relayed to operations rooms, where commanders directed fighter squadrons with precision and accuracy. Sector control rooms managed local defenses, while group headquarters coordinated multiple sectors across Britain. This real-time data flow enabled rapid, calculated interceptions, transforming chaos into coordination and giving Britain a vital edge in the skies.
