The Do17 is the least known of the trio of German twin-engined bombers used during the Battle of Britain. The He111 was numerically the superior, the Ju88 and Do17 were about equal in numbers. The Ju88 was a far more adaptable and high performance machine, which is why the Do17 had largely been withdrawn from front-line service by 1942. Another aircraft that was originally conceived as a passenger aircraft, the prototype made its first flight in the autumn of 1934. The slim fuselage was unsuitable for passenger carrying and the aircraft were mothballed. The following year, the type was prepared for a new role as a fast bomber, and by 1937 new versions of the Do17 were entering service with the Luftwaffe as bombers and reconnaissance-bombers.
Foreign observers at a military aircraft competition in 1937 were impressed with the aircraft's speed (248 mph / 400km/h) as it could out-pace some contemporary fighters. Like the He111, the aircraft saw service in the Spanish Civil War and fared equally as well against the Republican's fighters. The major production version was the Do17Z which appeared in 1939, capable of carrying up to eight machine guns and an increased crew of five.
