    AL-41F1S (izd.117S) have 14 500 kg of thrust which matches even the most optimistic figures for Su-37's engine. Either way Su-37 was simply larger frame, ie heavier and draggier. As to the speed, that is incredibly moot point. Su-37 or Su-27 could maybe go to Mach 2.35 but for only a few min. With M2.25 and newer canopy materials Su-35S is probably able to sustain it for longer, which is more important than the absolute top speed.

    Another aspect is that if the Su-35S with its new engines can supercruise... even with just a light AA payload it should vastly increase its range and flight performance and ability to move around the battle space quickly but without using too much fuel or generating too much of an IR signature.

    The Su-35S is just a much better aircraft.... and I would expect further upgrades later in its operational life. The new engines for the PAK FA could be fitted later and newer radar antenna and other electronics like towed decoys and other bits could be added later too. It has plenty of growth potential.

    Supercruize per USAF definition is M1.5+. Su-35S can't do that, it was more like M1.1 in clean config on a prototype. Even if it still can fly barely supersonic without AB (not certain at all) it would be in completely clean config.

    First of all, not to be snippy, but could care less about USAF definitions of anything.

    Being able to fly faster than the speed of sound without constant use of afterburner is what is relevant... even if afterburner is needed to get supersonic... I don't really care... flying fast without AB is what I was referring to with a light load of say 6-10 AAMs.

    Over time, as engines evolve and get more powerful, even if they can't do it now, they might be able to do it in the near future.

    Even if it still can fly barely supersonic without AB (not certain at all) it would be in completely clean config.

    It is hardly a draggy configuration... and if the Europeans can claim their eurocanards can supercruise I don't think it is unrealistic to suggest the Flanker might achieve the same at some stage.

    Of course even if it never supercruises then it still is a very large aircraft with very long flight range without external fuel tanks...

    Let's be honest here: Not a single Su-35 deal have been signed yet. Not one. It's pretty premature to speak about the Su-35 as some kind of export success.

    Are there plans to equip Su-35s, Su-30s with AESA radars? or does RF intend to use AESA only on PAK FA and succeeding aircrafts?

    India is asking for AESA in their Su-30MKI "Super Sukhoi". If they actually get it remains to be seen. 

    As for the RF, I doubt it unless there is a further updated Su-35 released.

    If I remember correctly, Sergei Bogdan confirm, that Su-35S can supercruise, but it was never mentioned, at what speed. PAK FA can supercruise at M1.6, so we could assume Su-35S supercruise at lower speed, maybe around M1.3 or 1.4.

    They can go supersonic without AB and loadout because they were designed to, with particular aerodynamics. Not everything needs to be brute forced.

    If Russia planned to put the L-band radar on Su-35 wing like T-50, or any kind of unusual shape radar on the aerodynamic surface... then AESA will be needed.

    For now, with conventional nose-mounted radar, PESA is more than enough. It provides more powerful, cleaner and better quality for the radio waves, and radars like Ibris and Bars already have dynamic shifted phase.

    Flying at mach 0.98 or 1.1 without AB makes no real difference in real world.

    Flying at Mach 1.2 without AB instead of mch 0.8 without AB is a significant different in flight speed without additional fuel burn... for a large aircraft like a Flanker, that carries a lot of fuel anyway, that can mean a significant increase in flight range... for most aircraft flying supersonic reduces flight range by half or more.

    And again, it doesnt go supersonic without AB with a light load, missiles are just too draggy.

    Is that official statement or your opinion?

    the Flanker is a very big aircraft and in comparison a half dozen AAMs would hardly increase drag that much... they are designed to be supersonic too.

    Draggy would be fuel tanks... which it likely would not be carrying.

    Em, look how long it took to upgrade Al-31F, it was 12.500kg for aaaages before any modifications ever that had greater thrust made it to serial production. (not counting Al-31F in Su-33) There is no reason to update 117S in near future thrustwise, only reliability wise.

    They are already developing new more powerful engines for PAK FA, besides actual power is not that important for supercruising, it is the type of power that is important AFAIK.

    They can go supersonic without AB and loadout because they were designed to, with particular aerodynamics. Not everything needs to be brute forced.

    The engines on an An-124 are rather more powerful than most jet fighter engines but would be useless for supercruising.

    The Flanker is aerodynamic enough and already more aerodynamic than the F-22, the problem is dry thrust velocity/power.

    Here KNAAPO confirm, that Su-35 have multi axis TVC, what is 3D TVC as 2D TVC have only one axis.

    All ESA Radars be it PESA or AESA have phase shifters to steer beam, for fighter radar application we may have analog ferrite or digital phase shifter.

    The real future however is true time-delay beamsteering optically steered ESA's (This is not quantum radar) which use laser for beamsteering and beamforming instead of traditional feed network seen in older ESA's. But for now it seems it still complicated.

    It enables the radar to quickly oscillate the beam compared to the antenna surface.

    That means the radar can stand still while the radar beam quickly oscillate. Unlike static shifted phase radar, people has to oscillate the radar antenna to change the direction of the beam.

    Irbis and Bars use both dynamic shifted phase and mechanical oscillation of the radar antenna to enlarge the angular vision. The radar beam can oscillate in a 120 degree angle on the antenna, and the antenna can oscillate in a 120 degree angle. That mean Su-30/35 can "see" 240 degree.

    In dynamic shifted phase, the radar beam can oscillate very fast, much faster than the mechanical oscillation. But as the beam move far away from the perpendicular position compare to the antenna surface, its cross-section area decreases. That means you need a relatively big radar in order to effectively carry out dynamic shifted phase. Su-30/35/27 have relatively large radar, 90cm - 1,1m diameter.

    Sorry for my bad English.

    All ESA radar be it Irbis or US APG-77 Is able to change beam direction without moving its antenna.


    There are no "Static shifted phase radar" You might be confused it with Slotted Planar Array antenna. Yes technically given that it also an "array of antenna that has a feed network with same length to equalize phase" It can be considered as "Phased array" But since the antenna does not contain phase shifter..it cannot steer the beam electronically.

    That is ok. Nonetheless it's rather confusing. "Oscillate" may not be the correct term to use because it's often associated with wave not mechanical movement. Just use "Scan"

    and about the aperture foreshortening due to beamsteering. well it has no relationship to antenna size. The effect of aperture foreshortening is same be it at large or small antenna.

    Not sure if this is new news

    The Russian Defense Ministry and the United Aircraft Corporation (UAC) will sign a contract for the delivery of 48 Sukhoi Su-35 aircraft (NATO reporting name Flanker-E) at the MAKS-2015 air show in late August, local media reported Tuesday.

    MOSCOW (Sputnik) — According to the Vedomosti newspaper citing defense and industry sources, the contract may amount to 100 billion rubles ($1.6 billion at current exchange rate).

    Earlier this year, Russian media reported that the Sukhoi aircraft manufacturer, a subsidiary of UAC, was planning on transferring 14 Su-35S fighter jets to the Russian Defense Ministry this year.

    According to military expert Konstantin Makienko cited by Vedomosti, this deal will be the largest one for the Russian Air Force since 2012, when it signed contracts for the delivery of 92 Su-34 bombers and 60 Su-30SM fighter jets.

    I expect Russian MoD will order around 60 Su-35S as it was mentioned months ago. They need 60 planes to form 4 combat regiments as one squadron is in Lipetsk and in Akhtubinsk.

    Not going to sound like doomsayer or anything, but they can and should sign during MAKS rather than "at a later date, sometime this year". We heard this about various aircrafts (MiG-35s come to mind). I fear that Russian government wont sign for anymore and they will either opt for something else or just stop buying new aircrafts.

    http://foxtrotalpha.jalopnik.com/russias-stealthy-new-fighter-was-ok-but-the-su-35-stol-1727983756

    Russia’s biennial super air show and arms bazaar wrapped up last weekend and the highlight of the show wasn’t Russia’s newish stealthy fighter, the Sukhoi T-50. Instead it was the breathtakingly maneuverable ultimate version of Sukhoi’s renowned Su-27 Flanker series of fighters, the Su-35S Super Flanker. Watch what it can do.

    Although the Sukhoi T-50 flew a more energetic routine at the MAKS show this year than its inaugural appearance in 2013 when the jet was still in its early prototype stage, it could not compete with with seemingly physics bending pedal turns, somersaults and nose pointing capabilities of the Su-35S, the T-50’s generational predecessor.

    Watch the videos below to get an idea of just how wild this display was. Be sure to keep an eye on the Su-35’s 3D thrust vectoring nozzles that work independent of one another.

    If you are a fan of vapor capes and wing vortices, the Su-35 flew on Friday right as the cloud cover was breaking up, which offered some incredible atmospherics. Considering the Su-35 weighs over 40,000 pounds empty, that is a lot of mass rumbling through the sky.

    Here is the T-50’s demo for comparison with the top video shot on a fair weather day and the bottom shot on Friday among the breaking clouds.

    Here is also a the carrier-borne MiG-27K’s demo which seemed like an exact mix between the Legacy Hornet demo and the F-16 Viper demo back here in the states.
    The Su-30 has been sort of a canvas for which Sukhoi has painted their most aggressive Flanker dreams on for almost three decades. Different versions have flown over the years, some with canards, experimental systems, wild paint jobs and all with increasing levels of technology. Now that the Flanker has reached maturity, the Su-35BM configuration has rolled into a final production example in the guise of the Su-30S, of which Russia currently a few dozen in service out of an initial order of 48 aircraft. An additional 48 Su-30S order was announced at MAKS this year.

    This number will probably grow even further in the not so distant future as the T-50’s high cost and Russia’s faltering economy have become barriers to putting the 5th generation fighter into widespread production. Russia has also been working for close to a decade at finding a buyer internationally for the Su-35 without success.

    Regardless of if the jet ever flies in another nation’s colors, it will remain the king of fighter air show demonstrations for the foreseeable future.

    Assurances for future Mig-35 orders have been giving numerous time, but still nothing concrete, so let's say around the time hell freezes over would be my best guess, give or take. Mad
