The Sukhoi Su-35 is dramatic evidence that Russia can still create advanced warplanes. It is a further development of the Su-27, giving Moscow a new "top gun" with no PUBLICALLY KNOWN equal in the West. The Su-35 introduces new flight systems and the super-long-range KS-172 missile, able to span vast distances to destroy AWACS aircraft. This is one of the world's hottest fighters.
