Formerly known as the Su-27M, the Su-35 is an advanced development of the highly successful Su-27. The Su-35 features more powerful engines, improved radar and avionics, integral ECM pods, two-dimensional thrust vectoring, and a rearward-facing radar similar to that in the Su-34. Also, like the Su-34, the Su-35 can carry specially modified, rearward-firing AA-11 missiles in addition to more conventional munitions.%n
