During the dark days of 1940, when Britain faced the might of Hitler s armed forces alone, the RAF played an integral role in winning the Battle of Britain against the Luftwaffe, thus ensuring the country’s safety from invasion.

From setting up the ground-breaking radar systems along the coast of the Southeast of England, to the distribution of spotters of bombing waves coming along the Thames Estuary, the boffins who designed and built the guidance and detection structures to organise a winning defence umbrella, to the Wrens who plotted enemy movements and then conveyed this to the various RAF squadrons stationed in the UK’s zonal defence system.
