No. 100 Group — Bomber Support
Bomber Command
No. 100 (Bomber Support) Group was formed in late 1943 to wage the electronic and night-fighter war in support of the main bomber force. Its squadrons flew radio-countermeasures aircraft that jammed German radar and radio, and long-range de Havilland Mosquito night-intruders that hunted Luftwaffe night-fighters over their own airfields and among the bomber stream. Based in Norfolk, the group’s secret work with devices such as Mandrel, Window and Serrate did much to reduce Bomber Command’s losses in the last eighteen months of the war.
