Janab False Flagger there is no way I can answer your query, and the country you support and its all whether friend is getting SU 35 which have RCS of 1 sq metre for sure. But to answer your post here it is
Super Sukhoi will most probably goes with the upgraded Bar N01 AESA Radar, if so the cannard is not going to be removed. If you are considering the use of the cannard in Rafale and still have low RCS, then the Rafale's cannard is designed well and positioned in the perfectly as compared to MKI. In case of EF the cannard is very small.
The size of the MKI also makes it difficult to reduced its RCS considerably. Now if you argue Su 35 then pls read my earlier post for the answer.
Super Sukhoi rull reports have not yet released, but what we heard or what we speculate from its model, is that Super Sukhoi well be upgraded with internal Jammer- virgilus jammer, 2 wing tip Escort jammer, ariel decoy, MAW, RWR,LWS, Shiva ASPJ Pod, upgraded mission computer, upgraded display computer, glass cockpit. As far as the airframe strengthening is concerned, the Super Sukhoi after strengthening could carry KH-31, KH-35 for SEAD mission and for DEAD with 3 Brahmos NG(mini).
Now Super Sukhoi Su30MKI would be carrying out SEAD, DEAD, and Anti-ship role and ground attack but still it won't be the strike fighter, like Su-35, nor dedicated ground attack fighter like Su-34 because it is not certified to fly at low level with full load, and will be delivering the weapons from the strandoff range. And during SEAD and DEAD mission, the Virgilus Aesa based jammer, Escort jammer, and aerial decoy and its sensors will help Super Sukhoi when flying at high altitude.
