Kampfgeschwader 76 (KG76) was formed on 1 May 1939 in Austria and fought in most of the WW2 battles. After being trained on Dornier Do.17 E at the end of 1939, the formation adopted the Dornier Do.17 Z, used during the Battle of Britain.
Designed in the early 1930s, the Dornier Do.17 was one of the most important German bombers during the first years of the war. The Do.17 Z was its most advanced version, with a new cockpit design, extended to insert a rear firing gunner, new more powerful engines, and more effective defensive armament. First adopted in 1939, the Z-version was also used for reconnaissance missions and as a night fighter. The Z-version was extremely resistant to enemy weapons and able to execute disengagement dives at high speed.
