The Sukhoi Su-35S Flanker E is a highly modified and improved derivative of the Su-27. About 20 years later a heavily modified member of the Flanker family was produced and given the title of Su-35S Flanker E. Considered by many to be the most capable fourth generation fighter in the sky and equipped with many fifth generation technologies. This probably will be the last of the Flanker family when the fifth generation Russian aircraft arrive.
