No. 8 Group RAF (8 Gp) was a Royal Air Force group which existed during the final year of the First World War and during the Second World War.
No. 8 Group was formed in April 1918 as a training unit and designated 8 Group (Training). It remained in this function throughout the rest of the war and was disbanded in May 1919.
The Group was re-established as No 8 (Bomber) Group on 1 September 1941 only to be disbanded around five months later on 28 January 1942.
See main article: article and Pathfinder (RAF). 8 Group was re-constituted when Bomber Command's Pathfinder Force was renamed No. 8 (Pathfinder Force) Group on 8 January 1943. The group consisted of specialist squadrons that marked targets for the main attacks of Bomber Command aircraft. The Force, which had been formed in August 1942 with five squadrons from the existing Bomber Command Groups, flew a mix of Short Stirling, Handley Page Halifax, and Avro Lancaster, all four-engined heavy bomber aircraft, along with Vickers Wellington, a twin-engined, long-range medium bomber aircraft. When new aircraft, such as the de Havilland Mosquito, a twin-engined, multirole combat aircraft became available, 8 Group got the first ones. Its aircraft used navigation aids such as Gee, H2S and Oboe to find the targets of attack more accurately than the main force on its own could. Initially formed of five squadrons, 8 Group ultimately grew to a strength of 19 squadrons.[2]
No. 8 Group was also responsible for the Light Night Striking Force, equipped with Mosquito bombers and used for harassing raids on Germany. It was disbanded on 15 December 1945, though its badge and motto ("We Guide to Strike") were subsequently authorized on 11 March 1953. While the majority of Pathfinder squadrons and personnel were from the Royal Air Force, the group also included many from the air forces of other Commonwealth countries. The PFF flew a total of 50,490 individual sorties against some 3,440 targets. The cost in human lives was grievous. At least 3,727 members were killed on operations and 675 aircraft lost.
