The Russian Air Force is buying 48 Su-35S fighters. The Su-35S is actually a much upgraded Su-27 (as opposed to the Su-30, which was a redesigned Su-27). The 25 ton Su-35S was designed for maximum maneuverability. And even sports a new type camouflage pattern. The Su-35S is also a very capable bomber, and can carry eight tons of bombs and missiles. It has a 30mm autocannon and is equipped to deliver smart bombs and air-to-ground missiles. Some have compared the Su-35S to the U.S. F-15E (an F-15 fighter upgraded into a very capable fighter-bomber).
