    Downed kh-101 used tech from the 80s.

    No need to improve if it works.

    Make more kh-101 than AD missiles is the key to win a war.

    The PIC production starts in 2024 and ROFAR works on PICs, Now of course they did say they had aircraft version prototypes meaning those prototypes had to have PICs in order to function and the 2nd Su-57 phase supposedly has new avionics where the test phase end in 2024 with the new engines. PICs are even highly recommended for 6G wireless networks because the higher the frequency the faster the data transfer. millimeter wave radars on PICs operate 100 times better in performance than millimeter wave radars on MMICs, I even hope the production numbers on PICs would be big enough to supply 100s of Hermes MLRS systems with 100s of those missiles millimeter radar homing heads.

    The volume of deliveries of the fifth generation Su-57 fighters to the Russian Aerospace Forces will increase in 2023
    UAC enterprises fulfilling the state defense order, thanks to state support, received a significant amount of funds under the program of technical re-equipment and modernization of production, said Yury Slyusar, General Director of the United Aircraft Corporation

    MOSCOW, 23 June. /TASS/. The volume of deliveries to the Aerospace Forces (VKS) of Russia of the fifth generation Su-57 fighters will be increased in 2023, Yury Slyusar, General Director of the United Aircraft Corporation (UAC), said on Friday.

    "We will continue to fulfill our obligations under the concluded contracts. Su-35 aircraft of the following batches are in production. In addition, this year the volume of deliveries of the fifth generation Su-57 fighters to the Russian Aerospace Forces will increase," said the head of the UAC, quoted by the press. government service.

    As Slyusar noted, UAC enterprises that fulfill the state defense order received a significant amount of funds through the program of technical re-equipment and modernization of production thanks to state support. They put into operation new production facilities and facilities, which allows increasing serial production and increasing production volumes.

    Powerful weaponry makes Russian Su-57 fighter 'capable of anything': Military Watch , 06.26.2023.

    The new and powerful Russian Su-57 fighter capable of performing a big, Miss, combat with its impressive armament, says the American magazine Military Watch.

    "The weapons on board the fighter are impressive and the aircraft is compatible with a wider range of weapons than any other aircraft of its generation," the article states.

    The Su-57's use of stealth technology during the Ukrainian conflict allowed it to carry out far more complex combat missions than any other stealth aircraft in the world has ever done.

    The Su-57 is a Russian fifth-generation multirole fighter developed by the Sukhoi company.

    The aircraft is designed to destroy all types of air, ground and surface targets.

    The fighter has supersonic cruising speed, intra-fuselage armament, radio wave absorbing coating, as well as the latest set of onboard equipment.

    I don't read Russian... that engine at the bottom with the odd shaped nozzle... is it actually related to the Su-57 or could it be the nozzle for the S-70 drone that we have seen with a stealth rear end?

    Presumably both would have the same engine, but different performance requirements... for instance the Su-57 needs to supercruise and fly quite a bit at supersonic speeds which might make this more stealthy nozzle less useful, but the subsonic only S-70 might use it so it can fly deeper into enemy or contested airspace with a more stealthy rear end.

    About RCS of F22...this is real walues not mambo jambo from lockeed martin bulshit...

    https://servimg.com/view/19411875/4

    For F22 RCS is from 0.3-0.4m², similar to the Su 57s....

    Typical comparisons of RCS you see online of US and Russian fighters are BS. They talk about Lockheed Martin numbers which supposedly are derived from frontal stealth due to shaping and stealth materials plus coatings, and compare with Russian numbers just due to shaping. They do not even compare RCS number with same frequency on US vs Russian fighters. It is just plain BS altogether.

    The Su-57 has a shorter body and way smaller tail. It likely has smaller RCS on the side than the F-22.

    Claims of Su-57 having worse frontal RCS are due to engine blades being more exposed on that design and the IRST being round shaped.

    The US does not even have proper IRST on either the F-22 or F-35 which means those fighters are totally dependent on radar for targeting opposing aircraft at medium distances.

    The AL-41F1 engine uses coatings to reduce frontal RCS. Russia is also working on adding composite fan blades and other RCS reducing features to the Izdeliye 30. Sukhoi explicitly chose this design instead of using S-ducts to hide the fan blades like in the F-22 and F-35 because that comes at a significant performance penalty in terms of speed and overall aerodynamic efficiency.

    The amusing thing is that the story normally pedalled is that the stealth level is log based so to get 1% more stealth it costs 10 times more, to get 10% more stealth is costs 1,000 times more etc etc, so the reason western stealth fighters are so expensive is their higher stealth levels... but it seems that is bollocks too.

    Yes, Russians did serious studies on the F-22 years back, and what is interesting, so did the Chinese and the results are almost identical, and far from the bloated 0,0001m2!

    There is no doubt that the Su-57 is currently the most advanced machine of this class in the world. It promises to be that she will not have an equal competitor for a long time. Unless the US with its NGAD project will make a surprise.

    Even if the Su-57 is not the worlds bestest super plane, it is damn good value for money and an amazing product that most other third world gas stations couldn't produce let alone design.

    The cool thing is when they start exporting them and the west either comes up against them or gets their hands on them and realises how much super new technology Russia must have stolen from the west to be able to make them this good.

    Even more amazing they stole scramjet technology from the west and even made it work so they have hypersonic missiles when the west does not.

    The irony is that a pigs nose is discerning enough to find truffles, so as good as any dog... my understanding is that pigs are also used along with rats and dogs to find landmines, so calling them pigs might be giving them too much credit.

    Russian Su-57 has begun tests of the new "sixth generation engine" with flat nozzles and a variable thrust vector.
    It's apparently the further development of the Izdelie-30 engine. Up to 90% of the nozzle parts are made by additive technologies
    [printed on a special 3D printer].
