RAF 100 GROUP THE BIRTH OF ELECTRONIC WARFARE

Wartime operations under RAF No.100 (Bomber Support) Group were highly secret. Not even the RAF or main bomber forces which they protected knew of their existence. The principal tasks for No.1 00 Group were: to provide direct support to the RAF bomber offensive by using RCM, Window and night intruder operations with Mosquitoes; to exploit enemy air and ground RCM; to investigate the development of enemy radar and radio equipments by airborne signals intercept, done by lead Squadron No. 192; to build a body of knowledge as a basis for planning future operations; and to make use of immediate information about enemy fighter movements. Also vital were RAF Y-Service – the progressive analysis and interpretation of German Air Force radio traffic and Bletchley Park Air Section – the Intelligence output from the Air Section at Bletchley Park supplying Bomber Command with knowledge of enemy night fighter intentions and their execution. At the end of the war, Bomber Command held the view that No.100 Group’s operations had saved at least 1,000 bomber aircraft and their aircrews and brought the war to an early conclusion. 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.
