 In the West, due to the lack of available information, early details of the MiG-21 often were confused with those of similar Soviet fighters of the era.In one instance, "Jane's All the World's Aircraft 1960–1961" listed the "Fishbed" as a Sukhoi design and used an illustration of the Su-9 'Fishpot'.The MiG-21 was the first successful Soviet aircraft combining fighter and interceptor characteristics in a single aircraft.
