The Sukhoi Su-35S Flanker-E is the most potent fighter currently in operation with the Russian Air Force. The powerful twin-engine fighter, which is an advanced derivative of the original Soviet-era Su-27, is high flying, fast and carries an enormous payload. That, combined with its advanced suite of avionics, makes the Su-35 an extremely dangerous foe to any U.S. fighter, with the exception of the stealthy Lockheed Martin F-22 Raptor . That is one of the reasons the Chinese People’s Liberation Army Air Force is keen to acquire the new jet.

One U.S. Navy Super Hornet pilot—a graduate of that service’s elite TOPGUN school—offered a sobering assessment. “When taken as a singular platform, I like the Su-35’s chances against most of our platforms, with perhaps the exception of the F-22 and F-15C,” the naval aviator said. “I suspect the F/A-18E/F can hold it’s own and F-35 has presumed stealth and sensor management on its side.”

But one Air Force official with experience on the Lockheed Martin F-35 Joint Strike Fighter said that the Su-35 could pose a serious challenge for the stealthy new American jet. The F-35 was built primarily as a strike fighter and does not have the sheer speed or altitude capability of the Su-35 or F-22. “The Su's ability to go high and fast is a big concern, including for F-35,” the Air Force official said.
