Confounding the Reich: the Raf's Secret War of Electronic Countermeasures in Wwii

On 23 November 1943, 100 (Bomber Support) Group of RAF Bomber Command was formed. The object was to consolidate the various squadrons and units that had been fighting a secret war of electronics and radar counter-measures, attempting to reduce the losses of the heavy bombers--and their hard pressed crews--in Bomber Command. This secret war involved the use of air and ground radaris, homing and jamming equipment, special radio and navigational aids, and intruding night-fighters to seek our and destroy their opposite numbers.
