No. 205 Group

No. 205 (Heavy Bomber) Group was a long-range, heavy bomber group of the Royal Air Force (RAF) established on 23 October 1941 by boosting No. 257 Wing to Group status.

During the North Africa Campaign in Egypt and Libya, the successful coordination of No. 205 (Heavy Bomber) Group under Air Commodore Alan P. Ritchie with No. 201 (Naval Co-operation) Group under Air Vice Marshal Hugh Lloyd, and Air Headquarters (H.Q.) Western Desert under Air Vice Marshal Arthur Coningham, provided a functional organization of the air forces using a "tri-force" model. At the Casablanca Conference in January 1943, British Prime Minister Winston Churchill, American President Franklin D. Roosevelt, and their staffs reorganized the Allied air forces in the North African and Mediterranean Theater of Operations on this model. The result of this reorganization was the Mediterranean Air Command commanded by Air Chief Marshal Sir Arthur Tedder and its major sub-command, the Northwest African Air Forces (NAAF) under Lieutenant General Carl Spaatz, was structured according to the tri-force model.

This model which separated the command into strategic, coastal, and tactical air forces was presented to the Casablanca planners by Tedder who along with primarily Ritchie, Lloyd, and especially Coningham, implemented and developed the tri-force model in Egypt and Libya during 1942. As the strategic component of the original tri-force, No. 205 Group contributed significantly to these developments.

No. 205 Group units were part of the attempted resupply of the Polish Home Army during the Warsaw Uprising Airlift.
