In the mid-1950s, Dornier Flugzeugbau GmbH of West Germany developed the single engine Do 27 Short Take-Off and Landing (STOL) lightweight utility-minded aircraft. This little high-wing cantilever aircraft went on to a very successful service life with many variants and operators through both civilian and military markets. From this design came a new offering, a two-engine version of the Do 27 which became the Do 28 of 1959. This model emerged with the same high-wing layout and a pair of underslung Lycoming engines driving three-bladed propellers. The Do 28 retained many of the key qualities of the Do 27 before it including its STOL capabilities.
