The Sukhoi Su-35 is a single-seat, twin-engined supermaneuverability 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.
Among the Su-35 design features, worth of note is the absence of an overhead brake flap, a standard characteristic of the Su-27. Its functions are performed by an active rudder.
The Su-35 chassis has been reinforced because of the increased takeoff and landing weight of the aircraft. For the same reason, the front bearing has two wheels. The improved radar stealth reduces the reflectance of the Su-35 in the X radio waveband and in the angle range of ±60°.
Another important difference of the Su-35 from predecessors from the Su-27 family is the use, in its power plant, of new engines with an increased thrust. Those engines, known as 117S.
