    Yup ! the tail cone? Maybe an additional radar at the end, looks like a radome?

    Yup, correct answer.
    It is T-50-1 with screw-dumping parachute container in the tail boom.

    Cool! That's a pretty uncommon capability, but kind of essential for us cold weather climate countries, though Sweden uses canard braking instead. Among the F-16 and F-35, ours are outfitted with a parachute for landing on icy runways, which is unique on the F-35, but shared with a few other countries on the F-16, so it makes sense for Russia to do the same.

    Notice the stinger on the Norwegian F-16? That's a hold for a drogue chute.

    Given previous Russian aircraft had one, it's hardly a surprise they'd retain the capability.

    Ok, that's enough out of me on this thread.

    How is Russia planning this as a stealth aircraft when IRST will spot it at full ramge given the size of those engines.

    Dirty fighter as being speculated.

    Plus as engines are exposed and obviously wont be coated or shielded normal radar will also pick it up at normal ranges thereby cancelling any stealth capability.

    it is still waiting for its engine which is specially designed for it...

    I edited my post.

    But your answer covers that query as well.

    The RCS of PAKFA is the same as that of Rafael at 0.5 m2. I doubt the new engines will make any difference to the RCS as their is no provision to shield the engines like F-22. F-35 also shares the same problem.

    RCS of PAK-FA is still a hypothetical figure because it is still in developmental phase.
    But for RAFALE, My understanding is that Rafale had features that help suppress the IR signatures like extra engine cooling channels that most aircraft don't have.
    Rafale’s infrared signature is less than that of its competitor due to it’s two channel engine cooling ,a blast of cool air bypasses from fan of jet engine to around the engine exhaust which makes it difficult to lock on with infrared missiles a the cooler air shields hot exhaust to some extent , thus preventing higher infrared emissions.
    The F-35 meanwhile has a massive IR signature.

    May be, but that numbers are for the Clean configuration, and after arming the Rafale with the externally mounting weapons on its pylons, the RCS number you just shared will be highter, but in case of the PAK FA the weapons will/could be internally mounted, giving a clean config RCS.

    Anish the one which is flying is the T-50 Prototype only, and for the PAK FA the engines will be shielded with the Composite panels. Second the PAK FA/ PMF is designed to have the stealth from the front and Russian design sacrifice some of the Stealth for the Aerodynamic superiority. Third no one except USA have the 5th Generation turbofan engine with the square nozzle. forth F22 Raptor design shielded the engine from the sides, but the matter of the fact, the aircraft surface too generates the heat due to the air friction, and even F22 is not the exception. If you really wants the all round, Real Stealth that the Plane design is pretty close to the B2 and size equal to it.

    Not seeing B2 challenging air space controlled by S-400.
    Why dont USA check its stealth in Sryia - Assad office & residence is well known.

    Stealth only works against 3rd world/weaker countries, B2 will hardly be stealthy against S500

    Stealth won't be there if the radar is working on bigger amplitude say 1 mt long, this is exactly what the Serbian technician did with its Buk's targeting system's Radar. B2 example was given because it gives you stealth features from all aspects, and its size allows it to give the low RCS characteristic even with the said modification, plus its Subsonic Speed with lower down the low IR detection. Hope you get the idea.

    Don't give me the example of Asad, Russia, and the US led coaliation and Turkey-Saudi plans in the Syria and Iraq. What ever we are seeing in the news is far different that the background tussle over the so called planned oil line from Saudi to Turkey for the European market, thus challenging the Russian interest.
