The Sukhoi Su-35 (Russian: Сухой Су-35, NATO reporting name: Flanker-E) is a single-seat, twin-engined supermaneuverable multirole fighter. It is a derivative of the Su-27 'Flanker', and was initially known as the Su-27M. More than a dozen of these were built with some used by the Russian Knights aerobatic demonstration team. The Su-35 had been offered to many countries, including India, Brazil and South Korea.
