RAF 100 Group 1939-43 : The Birth of Electronic Warfare
Air battles over Germany were becoming intense and complex by the Autumn/Winter of 1942. There was deep concern about the escalating losses of RAF night bombers and the ever increasing effectiveness of the German air defence system. Something drastic was called for, and this came in the concept of establishing a specialist RAF unit to become responsible for the operational development, application and co-ordination of all RCM (Radar Countermeasure) programmes, from the air and from the ground.
Bomber Command suggested the role for what became No.100 Group in June 1943, to include specialist RCM aircraft from the 8th USAAF. The Group was officially inaugurated on 8 November 1943. Its first operation was in December 1943.
However, those who served under RAF 100 Group received no medal, and even to the present day, is not recognised for the work they achieved.
