Sturzkampfgeschwader 3 (StG 3—Dive Bomber Wing 3) was a Dive bomber wing in the German Luftwaffe during World War II and operated the Junkers Ju 87 Stuka. The wing was activated on 9 July 1940 using personnel from German medium bomber and other dive-bomber units. StG 3 was one of the few dive bomber units created during the war. StG 3 fought its first campaign in the Battle of Britain a short time after formation. In 1941 it served in the Balkans Campaign and then some groups served on the Eastern Front, from 1943, until disbanded. The wing operated through most of the North African Campaign and some of its units fought to destruction there. StG 3 also served in the Battle of the Mediterranean and spearheaded the last German campaign-sized victory in the Dodecanese campaign in autumn 1943. The wing redesignated to Schlachtgeschwader 3 (Battle Wing) on 18 October 1943. The Luftwaffe possessed several dive-bomber wings equipped with the Junkers Ju 87 Stuka in mid-1940; the Ju 87 having proved its effectiveness. StG 1, StG 2 and StG 77 were most experienced. A fourth wing, aside from smaller units such as StG 5, 76 and 151, was formed to increase dive bomber capability and organisation. A Stabsstaffel (command staffel) was formed from Stab./KG 28 (Kampfgeschwader 28 — Bomber Wing 28) at Dinard, France on 9 July 1940. According to strength reports, the command staff had four Dornier Do 17Z, one Do 17M, and two Heinkel He 111H aircraft all previously operated by KG 28. There is no mention of any Ju 87s with the Stab./StG 3 in 1940. By 13 August 1940 StG 3 had been subordinated to Fliegerkorps IV under Luftflotte 3. The command unit was relocated to Brètigny, south of Paris. Oberst Karl Angerstein became the wing's first commanding officer (Geschwaderkommodore) but was replaced on 27 July by Oberstleutnant Hermann Edert. I./StG 3 was formed near Barly, southwest of Arras. The strength of the group is unknown, but the experienced Major Walter Sigel as commanding officer (Gruppekommandeur). II./StG 3 was formed from I.
