An Iranian indigenous built Shahed 278, a lightweight helicopter that resembles the Bell models. Iran's Aviation Industries Research Center (AIRC) describes the Shahed-278 as a purely civilian design, but later it said that the platform will be used as a light reconnaissance helicopter, armed with weapons and sensors. Test flights of the Shahed-278, in military service designated Oh-78, began in late 2004. The Shahed 278 makes use of airframe and dynamic components of the Bell 206 Jet Ranger. When produced, this helicopter will be built by Iran Aircraft Manufacturing Industrial Company (HESA).
