Key point: The Su-35 is really good, but it might not match America's F-35.
The Sukhoi Su-35 Flanker-E is the top Russian air-superiority fighter in service today, and represents the pinnacle of fourth-generation jet fighter design. It will remain so until Russia succeeds in bringing its fifth-generation PAK-FA stealth fighter into production.
Distinguished by its unrivaled maneuverability, most of the Su-35’s electronics and weapons capabilities have caught up with those of Western equivalents, like the F-15 Eagle. But while it may be a deadly adversary to F-15s, Eurofighters and Rafales, the big question mark remains how effectively it can contend with fifth-generation stealth fighters such as the F-22 and F-35.
The Su-35 is an evolution of the Su-27 Flanker, a late Cold War design intended to match the F-15 in concept: a heavy twin-engine multirole fighter combining excellent speed and weapons loadout with dogfighting agility.
An Su-27 stunned the audience of the Paris Air Show in 1989 when it demonstrated Pugachev’s Cobra, a maneuver in which the fighter rears its nose up to 120-degree vertical—but continues to soar forward along the plane’s original attitude.
Widely exported, the Flanker has yet to clash with Western fighters, but did see air-to-air combat in Ethiopian service during a border war with Eritrea, scoring four kills against MiG-29s for no loss. It has also been employed on ground attack missions.
The development history of the Su-35 is a bit complicated. An upgraded Flanker with canards (additional small wings on the forward fuselage) called the Su-35 first appeared way back in 1989, but is not the same plane as the current model; only fifteen were produced. Another upgraded Flanker, the two-seat Su-30, has been produced in significant quantities, and its variants exported to nearly a dozen countries.
The current model in question, without canards, is properly called the Su-35S and is the most advanced type of the Flanker family. It began development in 2003 under the Komsomolsk-on-Amur Aircraft Production Association (KnAAPO), a subcontractor of Sukhoi. The first prototypes rolled out in 2007 and production began in 2009.
