The Su-35, as well as the Su-34 and Su-57, are produced at the Komsomolsk-on-Amur facility in Russia’s Far East. “We produce Su-35S aircraft at the highest technological level thanks to the large-scale modernization of production, which has been carried out at the Komsomolsk-on-Amur plant in recent years and is still ongoing,” said UAC General Director Yuri Slyusar.
