The Dornier Do 217 was a bomber used by German Luftwaffe during World War II as a more powerful version of the Dornier Do 17, known as the Fliegender Bleistift (German: "flying pencil"). Designed in 1937 and 1938, its design was refined and production began in 1940. It entered service in 1941 and by the beginning of 1942 was available in significant numbers. The Dornier Do 217 had a much larger bomb load capacity and had much greater range than the Do 17. The early Do 217E variants were more powerful than the Heinkel He 111 and Junkers Ju 88, having a greater speed, range and bomb load. Owing to this it is designated a heavy bomber rather than a medium bomber. The Do 217 served on all fronts in all roles. On the Eastern Front and Western Front it operated as a strategic bomber and reconnaissance aircraft. It also performed tactical functions, either direct ground assault or anti-shipping strikes during the Battle of the Atlantic and Battle of Normandy. The type also served in anti-shipping units in the Mediterranean, attacking Allied Convoys and Sea power during the campaign.

Jagdgeschwader 3 (JG 3) Udet was a Luftwaffe fighter-wing of World War II. The Geschwader operated on all the German fronts in the European Theatre of World War II. It was named after Ernst Udet in 1942.Jagdschwader 3 "Udet" was formed on 1 May 1939 in Bernburg/Saale from JG 231. JG 3 was one of the Luftwaffe's fighter units that took part in the Battle of France. A particularly fruitful period over France occurred from 14 17 May 1940. Allied bombers had attempted to prevent the German armour from crossing the Meuse and sent waves of inadequately protected bombers to do the job. As a result 90 Allied bombers were shot down and the 14 May became known as the "day of the fighters" within the Luftwaffe. I./JG 3 destroyed seven fighters without loss on this day. On 15 May five were destroyed, again for no losses.
