    Actually, no one is very concerned about the Stage 1. It is superior to the F-35 as it is, but it has not reached anywhere close to what it is supposed to be.

    The Stage 2 IOC is most likely 2020 or 2021. That's the real version of the aircraft. The FGFA IOC is 2023 or 2024.

    The first S2 prototype with the 117 engine took off in July, and we still haven't seen pictures of this prototype. So the main R&D is yet to start, and it will start once the FGFA contract is signed, so it will happen this year.

    Yeah right. Performance maybe, avionics, stealth, EW no.

    K-30, R-74 replacement. Based on ASRAAM, which Russians were very impressed with.

    Can you give more info on it ? I couldn't find any. Difference with K74M ?
    What will be primary BVR for PAKFA phase 2 ? @randomradio

    Basically an equivalent to Western WVR missile capability. 90deg HOBS, LOAL, IIR etc.

    In every way, even stealth. In fact, the F-35's stealth will be obsolete.

    Everything on PAK FA Stage 1 is already GaN.

    Many new missiles coming up. There is an initial low end version which is public knowledge and there's the secret high end version.

    BVR
    Low end: K-77M - GaN seeker, dual pulse motor etc. Ramjet version is also probably in the works.
    High end: Unknown. Could be ramjet, scramjet, hybrid, anything.

    WVR
    Low end: K-74M/M2 - QWIP seeker, probably dual pulse motor.
    High end: K-30. Unknown beyond the project name.

    LRAAM
    Low end: K-37M. Unknown, but pics are available.
    High end: Project 810. Unknown.

    K-77s are not reliable.Even they don't use it during this syrian conflict.
    K-37 is not a PAKFA missile, it will not fit in weapon bay.

    Oh yeah, nobody has even seen this PAK-FA AESA radar yet. And if you think it's stealthier with that IRST system, thing again. That alone has an RCS bigger than an F-35's, even without the rest of the aircraft. Then there's the visible engine face.

    K-77 isn't a missile. And the Russians don't operate the R-77 family anyway.

    The K-77M is expected to enter production this year end. This missile will be the first in the R-77 family for the RuAF. The older RVV-SD is an export version with basic tech, a bit inferior to the Aim-120D.

    K-37 isn't a PAK FA missile, but the K-37M is made for Mig-31BM and PAK FA. The one for PAK FA comes with foldable fins and can carry 4 of those internally.

    However the fact is none of the above missiles are meant for Stage 2. They were made for the Stage 1 program. More than 12 weapons are being developed. Stage 2 will come with PAK FA-specific weapons.

    Russia Testing New Engine for T-50 PAK-FA Stealth Fighter

    Russia expects to start testing a new engine for its stealthy Sukhoi T-50 PAK-FAfifth-generation fighter toward the end of 2017.

    Currently, the Russian stealth fighter is powered by a derivative of the Saturn AL-41F1S engines that are installed on the Sukhoi Su-35S Flanker-E called the AL-41F1, which was formerly known as the izdeliye 117. Though the AL-41F1 produces roughly 33,000lbs of thrust with full afterburner, the engine is not powerful enough to realize the full potential of the PAK-FA airframe. Thus, the Russians are developing a new engine that is currently designated as the izdeliye30 for eventual installation on the T-50.

    “The engine for the PAK FA should begin flight testing onboard the aircraft in the fourth quarter of 2017 to complete the remaining work,” Alexander Artyukhov, chief executive officer for United EngineCorporation told the Moscow-based TASS news agency. “The engine will be deployed between 2018 and 2020 after it passes state tests in 2020.”

    Under ordinary circumstances, an appropriate engine would have been under development for the PAK-FA before work started on the airframe design. However, the Russian defense industry was in a state of chaos in the aftermath of the collapse of the Soviet Union. As such, Moscow was not able to start developing an appropriate engine for the new aircraft ahead of time during the 1990s—which in many ways was a lost decade for the Russian defense industry.

    While there are few details available about the izdeliye 30 engines, the powerplant is expected to deliver 24,054lbs dry thrust and 39,566lbs of afterburning thrust. With the new engine installed, the PAK-FA should be able to offer kinematic performance comparable to the Lockheed Martin F-22 Raptor—cruising without afterburner at speeds exceeding Mach 1.5 with a maximum speed greater than Mach 2.0 at altitudes of around 60,000ft. “Performance-wise it certainly looks to compete with the Raptor,” one senior military official with extensive experience on U.S. fifth-generation fighters told me some time ago.

    Overall, while the Russians place less emphasis on stealth while focusing more on maneuverability and raw kinematic performance, the new Sukhoi-built jet appears to have a comprehensive suite of avionics. “The analysis that I have seen on the PAK-FA indicates a pretty sophisticated design that is at least equal to, and some have said even superior to U.S. fifth-generation aircraft,” former U.S. Air Force intelligence chief Lt. Gen. Dave Deptula told me a few years ago. “It certainly has greater agility with its combination of thrust vectoring, all moving tail surfaces, and excellent aerodynamic design, than does the F-35.”

    But while the Russians have developed active electronically scanned array(AESA) radars, infrared sensors and excellent electronic warfare systems, one of the big questions that remain is how well the Russians have integrated the jets’ avionics. It took the United States decades of effort and billions of dollars to develop the complex integrated avionics suite and sophisticated pilot vehicle interfaces that make the Raptor the fearsome weapon that it is. And indeed,sensor integration problems and software challenges still bedevil the F-35 program even as that aircraft enters operational service with an interim configuration.

    Ultimately, the Russians will probably be able to resolve technical glitches with the PAK-FA and field a capable operational aircraft. There is little doubt about that. The real question is when that will happen and how many jets the Kremlin can afford to buy.

    In the meantime, with the long and tedious F-35 development process nearing completion, the United States is gearing up to start development of next-generation fighters to replace the F-15C, F-22 and the F/A-18E/F Super Hornet.And the cycle starts anew.
