The Yakovlev AIR-13 was a projected twin-engined racing aircraft designed during 1935 in the Soviet Union, intended to participate in air races planned for 1936. Contemporary sketches show that the design bore a close similarity to the de Havilland DH.88 Comet, that had proved successful in the 1934 MacRobertson Trophy Air Race. The design did not progress beyond the drawing board.[1]
