Design

The Dornier Do 217 was a larger and faster version of the Dornier Do 17.1,3 It had better aerodynamics with a wider and longer fuselage.3

A requirement for the Do 217 was that it should be able to act as a dive bomber and some had large air brakes in the tail.2 This requirement was eventually withdrawn.2

Do 217K and Do 217M

In early 1942 the Do 217K and Do 217M were being developed and produced at the same time.2 The were basically the same except for the engines.2 The nose was enlarged and glazed.2

Do 217J and Do 217N

Night fighters that were converted on the production line.2 They had a stepped windscreen and solid noses containing the primary armament.2

Prototype

The Do 217V1 prototype first flew in August 1938.1,2,3 The prototype had problems with directional stability and controls that were sluggish.2 It crashed after having only flown a few flights.2
