Kampfgeschwader 51 "Edelweiss" (KG 51) (Battle Wing 51) was a Luftwaffe bomber wing during World War II.
The unit began forming in May 1939 and completed forming in December 1939, and took no part in the invasion of Poland which started the war.
It first served in the Phoney War then the Battle of France in May and June 1940. From July to October 1940, it fought in the Battle of Britain and then in the night intruder role during the Blitz until March 1941.
It supported the Balkans Campaign in April 1941 and served on the Eastern Front from June 1941 until December 1943.
In 1944 and 1945, it served exclusively in the West; in the Defence of the Reich, Western Front and in Operation Steinbock. All Groups and squadrons of KG 51 disbanded and reformed during the course of the war. Few remained active by the German surrender in May 1945.
The wing operated the Dornier Do 17, Heinkel He 111 and Junkers Ju 88 light and medium bombers, the Messerschmitt Me 410 heavy fighter and the Messerschmitt Me 262 jet fighter.
