The Heinkel He 74 was a light fighter aircraft developed in Germany in the early 1930s. It was a conventional, single-bay biplane with staggered, unequal-span wings braced with an I-type interplane strut. The pilot sat in an open cockpit, and the undercarriage was of the fixed, tailskid type.
It was designed in response to a RLM requirement for a Heimatschutzjäger - a light fighter aircraft suitable for purely defensive duties and which would have a secondary role as an advanced trainer for fighter pilots. Although it was not strictly a requirement of the specification, firms submitting designs were urged to use a monoplane layout.
During trials in 1934, the He 74 outperformed its competitors, but in the end, the RLM awarded it third place, behind the Focke-Wulf Fw 56 and Arado Ar 76, believing that since the fighters then being developed were all monoplanes, this configuration was essential for an advanced trainer as well.
