The '''SET 7''' was a military trainer & reconnaissance aircraft that was produced in Romania in the mid-1930s. It was originally designed as a conventional single-bay biplane, with slightly staggered wings, a standard undercarriage with fixed tailskid, and a tandem open-cockpit arrangement for the pilot and instructor or observer. Power was supplied by an [[Armstrong Siddeley Jaguar]] radial engine, and, from the outset, the aircraft was equipped for wireless & photographic reconnaissance duties.

An armed version followed in 1934, adding a trainable machine gun for the observer and a fixed machine gun for the pilot. This version, the '''7K''', was powered by a neatly cowled [[Gnome-Rhône 7Ksd]] engine, and the '''7KB''' (fitted with bomb racks) & '''7KD''' were specialised subtypes that followed it. A floatplane version was produced as the '''7H'''.
