Sukhoi PAK FA

Frankly, I don't see how come some experimental UHF GaN model introduced in 2014 suddenly mean Su-57 will use GaN for its radar and EW system, even ignoring the issue of frequency and architecture the main difference between real life and a video game is things cost money and a lot of time to build and integrate in large scale, and military always needs to care about reliability, cost overrun, so unless the technology was available while the aircraft is in the design phase, you will still have to wait until the first tech refresh till it can be implemented on the aircraft, and that is IF it ever being implemented at all. Things like Rofar are even further down the hypothetical line, assuming it doesn't get cancelled then by the time any fighter got Rofar, our 6 generations probably about to retired. There are much higher chance of we seeing fighter equipped with laser weapons than any of them equipped with Rofar

This is one of those why are such installments made on aircraft and why they would choose it. The IRST has material that has RCS reduction measures(yes they same as the fan blades) But there have QWIP IRST claim capabilities that have seen aircrafts at a way farther distance and with the infrared systems installed on the F-35 no one can decide how far or what kind of aircrafts they can detect with their infrared systems. Also with regards to the LEVCON there is more vortex and lift for the Su-57 as the trade-off with a better angle of attack and quicker stall recovery. But lets move on to why they still chose maneuverability for some features over stealth.

No one cares what your imagination brings you to, it is written in the patent that it comes with partial serpentine ducts. The reduction measures have been given in the patent but knowing the snake oil salesman of other 5th gen aircrafts you wont find an overall RCS reduction measure comparison they would do from 4th to 5th gen aircrafts. Your imagination is running wild again, radar blockers reflect the radio waves away from radar source along with RAM features for the engine, you cant determine any value reductions

I do not know if its a good idea that the F-35 does not have supersonic maneuverability, in fact I would feel sorry for an F-35 dog-fighting an Su-57. But there is one thing that cant be denied here and that is the F-35 is still undergoing block upgrades, even though F-35 production lines zerg rushed 100 aircrafts to come out. Such expenses of refitting new avionics become quite a paysome burden for the F-35. GaN modules for Himalayas, khibliny and tarantula were introduced in 2014. late 2014 the Su-57s were fitted with the himalayas, 2016 new khlibiny were tested in syria for su-35 and in 2018 tarantula was tested fitted for the Su-34. KRET already announced in their articles to have these modules on airborne aircrafts and EW systems. I do not recall the F-35 getting NJGs. KRET has also announced in 2019 photonic EW systems being made with news statements of ROFARs being integrated in the mid-2020s and of course not too long ago there has been announcements of new engines with new avionics. The F-35 did go from 1200 to 1600 modules but that was all done on the early phases and with the amount of aircrafts already produced I have my doubts they would start an avionics upgrade because they would have to re-test 100s of aircrafts with new systems on already operational aircrafts causing expenses to sky rocket.

Go find any article on the web but PICs have better receiver sensitivity than MMICs. Which would allow their aircrafts to quickly find and suppress aircrafts faster than aircrafts fitted with 1600 T/R modules. The Su-57 in early 2009 was given 2,236 modules and that is not counting the radar changes that were done to the Su-57 going from 240 to 360 degrees in a 2019 announcement, ROFAR is an even more monstrous upgrade than what they announced in 2019. With Stealth and far superior EW suppression the F-35 would basically be dog fighting this aircraft.

Materials,RAM don't help much if the design itself is not taken into consideration of reducing the radar waves,IRST like other 4th gen aircraft doesn't conform with main body itself and appears in the front of the main hotspot as a separate surface...let me tell you why they chose maneuverability because of their defensive doctrine,in almost all russain articles they mention su57 as an air defence fighter aircraft,no where they have mentioned it as an aircraft that will go into the enemy airspace.....why bring rhetorics over basic flaw,this is how the engines are exposed,they are kept just behind the intakes and sukhoi's intake has better tradeoff to the fluent air flow than hiding the engines,else the engine's would been kept behind the front fuselage than like the flanker families,moreover in the supersonic speeds the su57 will be way more visible than any other aircraft in the infrared spectrum due to this configuration of the engines.

Radar blockers have several limitations at several angle of attack it would require a very large intakes to provide the good airflow with the blockers on,moreover it's again a surface which is perpendicular to the radar waves,so it might offer good reduction from the same area in the some angle of attack ,it is not the choice for the whole flight envelope....F35 is getting block upgrades and it will till it remains in service,it is a continuous process and every successful aircraft goes into the same cycle, it has seen combat,bombed the so called chinese UHF radar and came out without getting detected... And the joke continues "GaN",a country which doesn't manufacture aesa radar on any of its fighter aircraft is selling GaN dream to many people....The day Russian induct their so called GaN radar and Photonic radars in the large numbers fabricate stories from then only or rather help me to find the foundry where Russians fabricate GaN MMICs....F35 hardware upgrade test is done on the prototype vehicle and upgrading a large fleet is rather less expensive than buying a small amount of 4th gen revamped as 5th gen and claiming it has everything one sees in fantasies.
Smaller size,higher bandwidth,low noise,lower sidelobes,this is what achieved when you progression occurs. Future ICs will definitely be superior to other but does Russians even have a decade old things,among any major airforce Russia is the only country which doesn't have an AESA radar on a fighter aircraft,the latest Su35 has a decade older pesa ...no Sukhoi had aesa in the 2009,it was only a PR claim.....and 360 degree claim of radars,then one must be jumping in l band on the wings, X band on the cheek and all the stuff,it is good to have all sorts of stuff in not so smart fashion,but is not operational as is the Su57...

Geez your starting to remind me of ActionJackson from keyaero. Its quite odd that indian users like haavarla or krivpapa do not have accounts here but over there it became a wasteland forum.
Lockheed Martin literally marketted a HAWC missile as a external missile on a F-35, while the Russians are pushing for a hypersonic air to ground missile to be fitted internally on a Su-57. I thought that someone like you that preaches about stealth like any other snake oils salesman would have not missed a detail like that. If you also compare the F-35 front DAS sensor and EOTS you don't have that luxury they would need to rely only on glass film coat to reduce return of their optical system which Idoubt it is better then RAS RAM combo as for the OLS-50 on the Su-57 which are adustable as the radar blockers that are used. The Su-57 was meant to go into enemy air space as well unless you must have missed its operational flights in Syria?

This is how engines are exposed.....OMFG are you trolling right now? why did you choose an early 2000s image because other prototypes do no look like that. I will repeat this 100 times if I have to but radar blockers prevent exposure, partial serpentine ducts further reduce it with RAM by obscuring the engine fact. The current engines feature thrust vectoring control and optimized radar cross section and infrared signatures for stealth as well. The izdelie-30 provides more stealth reducing enhancements for both of those. You do not have a 1 billion dollar radar chamber as the U.S. does or Russia to find out why they chose these designs......And I am not trying to throw a major insult at you but their designers at Sukhoi seem be ignoring what you and ActionJackson have suggested instead of re-designing ther aircrafts to look more like the F-22 or F-35. But they have their reasons in ignoring internet enthusiasts like yourself that have no calculated values to compare either aircraft.

I am going to summarize this on radars. ROFAR>GaN AESA >GaAS AESA> PESA. Your giving very old information(like the image you provided) about their MMIC industry which of course I agree with you is atleast 10 years behind the west. But the radar upgrade changes have only been done very early before production has hit for those aircrafts. https://ir.qorvo.com/static-files/f3b850ac-b1d4-4935-9236-6a81990ac89b and just like the early Su-57 it had GaAS AESA. But no radar upgrades have been done and you think its cheap to retrofit GaN for 100s of F-35s and even if you did do that your going to have to put operational aircrafts back at the testing lab because of new items. The Su-57 http://www.promweekly.ru/archive/kret/KRET_4-2017.pdf

"In the aircraft industry a role of composites
is increasing, a sixth-generation aircraft will
be possibly designed with use of the composite
materials. On-board radio electronic equipment
is being improved. Now the transmission power
of the transceiver module of the active phased
array antenna is 5–7 watts. After switching
to the use of gallium nitride in microwave
transmitters, the power can increase to 20
watts. Accordingly, the performance parameters
of the radar will improve, and its dimensions
will decrease."

2019 is the announcement of a 360 degree radar view of the aircraft with clams of new avionics.

2014 this was announced and in late 2014 is when the Su-57 got their latest EW system, 2016 new khlibiny was tested in Syria and May 2018 is when new tarantula systems were received for the Su-34. But I am not finished here just yet because the Su-57 that will be fitted with the new engines is getting a avionics upgrade and the one I am currently looking at is this.

“KRET and the Advanced Research Foundation have agreed to implement an advanced sci-tech project, named Development of the Radio-Photonics-Based Active Phased Array Radar (ROFAR). The project implies building a new specialised laboratory and developing a versatile technology that would form the hub of new-generation radars and EW systems. The investments in the project will amount to 680 million rubles. “Nanophotonics is a promising field of research, which will soon determine the vector of dual-use systems’ development in advanced countries,” said KRET’s Director General Nikolai Kolesov. “With the help of cutting-edge technologies as soon as in the 2020s we will be able to make efficient and advanced transcieving devices, radars and electronic intelligence and electronic countermeasures systems, which would replace the existing lineup.” The laboratory will be set up at KRET’s facilities. Making use of the concern’s test benches, it will ensure all the necessary conditions for research. Among other things, the laboratory will have the ‘clean room’ environment with a minimum level of dust, microbes and chemical vapors.”

http://www.promweekly.ru/archive/kret/KRET_4-2018.pdf

“RADIO-PHOTONIC TECHNOLOGIES IN ELECTRONIC WARFARE SYSTEMS In view of the above, much attention is given to the development of EW systems for the land, sea and airspace applications. EW systems cover almost all known types of physical fields – electromagnetic, including optoelectronic, and sound field. Extensive and continuous use of EW systems results in certain specific characteristics of their components, materials, technologies and general system approaches used in their design. One of the essential technological novelties currently being implemented in EW are the ultra-wide bands (UWB) operating within a frequency range of 10 to 100 GHz. Because of limited capabilities of methods and devices for identifying and tracking the enemy’s RE operations in UWB, small-sized efficient EW systems currently cannot be implemented and their development is seriously hindered. This problem can be solved through using a radio-photonic technology that will provide sufficient improvement of EW equipment combat potential and a steady continuous control of a practically unlimited frequency band.”

Would you like a performance comparison on this? I do not know where the U.S. stands right now in this field, but I do know that Italy tested the PHODIR project but their performance results have shown they have not achieved better detection capabilities where the U.S. Navy Lab chimes in saying they have same results as they do.

Cheers I know a counter is difficult to make than remembering the past...
I guess it requires no brainer to judge the size difference of the internal weapons bay of an aircraft which measures 15.7mts and an aircraft which measures over 20mts....even in the front DAS cameras are well conformed within the body and don't appear as a seperate surfaces.......

EOTS by design itself is more stealthier than carrying a full fledged targetting part...it is by
design only stealthier by all sides as it's surface is faceted and will reflect the radar waves on the other direction than too the source itself.....what shame of a comparison...
"operational flight in Syria" ,you mean to say a prototype vehicle with no initial clearance to fly in the combat zone was flying in the combat zone,did it participated in the combat,what missile did it fire,do you have any data of that , propaganda doesn't actually needs to fire weapons....

Lol genius should have bring some good point than pointing the image is of first or last prototype,the intake design has not changed since it was conceptualized,the near production variant has the same intakes...and this how your partial serpentine is looking like,RAM is applied on the internal walls of the intake which degrades the radio waves to a small extent,no RAM or RAS ever makes a protruding surface stealthy..repeating again and again,radar blockers are restricted to the ideal flights and not at all angle of attack....the current engine with thrust vector is nothing new or special,it's an advance variant of the troubled AL31FP...it has no measures of reducing anything when your engine blades are exposed like this...Izdeliye30 is a prototype and is not being operational with the going to produce aircrafts...yes and that's why America has F22 and F35 and Russians can only reach to the Su57 level. It requires capital and capability,dreaming doesn't lead to anything,Sukhoi's dream is limited to the flanker variants and it's advancement....

Tell you a fact bro,a superconductor based radar will be superior to all,ROFAR is a concept,the day Russians operationalize ROFAR that day only it will be worth to mention just like their aesa radar ....even the current Sukhoi 57 has GaA based electronics,they don't have any foundry to fabricate GaNs.

More stealthy based on what? you got a anechoic chamber or do you consider your own opinions as facts? Your shilling more harder than certain users here with multiple accounts on other forums. Videos are not propaganda its just that you keep projecting yourself on saying random shit based on what you think but of course far from reality. https://www.thedrive.com/the-war-zo...-su-57s-on-their-absurdly-short-trip-to-syria.

I want you to go take a look at the Su-70 right now. Do you think that the antenna and exhaust are the final design or do you think that the exhaust will be managed later like what they have shown in the maks 2019 airshow and that frontal antenna would be removed? The so called 1st and last prototype does not even look like that right now so at this point your just here to troll. RAM is not stealthy enough, composite stealth fans are not stealthy enough, RAS RAM combo is not stealthy enough is all based on your opinion which I and of course no one else cares about because you do not work for LM, Sukhoi or even have access to a anechoic chamber. Your just wasting my valuable time on this agan and again. And of course you getting desperate enough to spout more nonsense of radar blockers that come with retractable mesh screens to still receive airflow and increased supersonic efficiency that is not being effected. The partial serpentine ducts(not the very old prototype that you think is the final design XD) obstruct part of the fan blades which of course have stealth composites with the addition of RAM and radar blockers no one can tell what RCS values a particular aircraft will compared to the other.

Tell you a fact bro,a superconductor based radar will be superior to all,ROFAR is a concept,the day Russians operationalize ROFAR that day only it will be worth to mention just like their aesa radar ....even the current Sukhoi 57 has GaA based electronics,they don't have any foundry to fabricate GaNs.

The thing is KRET has stated GaN MMICs are present on aircraft EW systems, along with a working radar back in 2017. UHF still works in the firecontrol frequency and since 2019 they have stated 360 degree radar coverage pretty much points out that the tail where the EW system is located has radar functionality. You know a little deductive reasoning like that never hurts anybody. Deductive reasoning has also shown me that back in 2014-2016 they had plans to integrate ROFAR in the mid-2020s to this aircraft multiple times not just once. And the announcnement of not just new engines but new avionics(which of course include new things like radars) around mid-2020 pretty much is considered a red flag. 2014 there have been no breakthroughs for Italy or the US on PICs, the only breakthrough announcements of better performance than conventional radars has been announced by KRET. KRET and RTI currently do have PIC radar related projects on air balloons and aircrafts. RTI stated 2023-2025 is the expected time frame for PIC production so that basically narrows down the option. To get a hint of the capabilities of this said radar they say a mobile radar on a Kamaz truck has the same efficency as ground building radar. Chinese source has stated background noise gets lowered 100 times basically seeing a .01m2 target from 400kms instead of 1m2. I really do not care as much as what GaAS or GaN equipment is on the Su-57 for the 1st stage but my only concern is the 2nd stage.

I do not feel like talking too much about this even though its available publicly. I had a normal thread created on one forum by just putting up news information than that thread got deleted along with my account. Same story happens to another forum and ironically the admin at that one forum also had an account on that forum browsing that thread along with the other admin that is in control of that forum than of course account deleted for news updates and that is excluding the abnormal behavior when just throwing news updates on missile projects. What I learned from this experience is that there is a likelihood to military related forums that certain administrative authority figures have government related jobs which would make alot of sense because military related forums attract military personnel which would mean some classified information can be spilled which is why they are on the watch. And I can say the same for users that are suspected with multiple accounts. So far this forum along with another forum seem pretty chill so for users out there including yourself stay safe. I am saying this because maybe your opinions are based on the fact that you might work for lockheed martin which is why you know so much about stealth without the need of a anechoic chamber but you just cant state RCS figure estimates on certain features because you might get in trouble.

RAM is not stealthy enough, composite stealth fans are not stealthy enough, RAS RAM combo is not stealthy enough is all based on your opinion which I and of course no one else cares about because you do not work for LM, Sukhoi or even have access to a anechoic chamber. Your just wasting my valuable time on this agan and again. And of course you getting desperate enough to spout more nonsense of radar blockers that come with retractable mesh screens to still receive airflow and increased supersonic efficiency that is not being effected. The partial serpentine ducts(not the very old prototype that you think is the final design XD) obstruct part of the fan blades which of course have stealth composites with the addition of RAM and radar blockers no one can tell what RCS values a particular aircraft will compared to the other.



The thing is KRET has stated GaN MMICs are present on aircraft EW systems, along with a working radar back in 2017. UHF still works in the firecontrol frequency and since 2019 they have stated 360 degree radar coverage pretty much points out that the tail where the EW system is located has radar functionality. You know a little deductive reasoning like that never hurts anybody. Deductive reasoning has also shown me that back in 2014-2016 they had plans to integrate ROFAR in the mid-2020s to this aircraft multiple times not just once. And the announcnement of not just new engines but new avionics(which of course include new things like radars) around mid-2020 pretty much is considered a red flag. 2014 there have been no breakthroughs for Italy or the US on PICs, the only breakthrough announcements of better performance than conventional radars has been announced by KRET. KRET and RTI currently do have PIC radar related projects on air balloons and aircrafts. RTI stated 2023-2025 is the expected time frame for PIC production so that basically narrows down the option. To get a hint of the capabilities of this said radar they say a mobile radar on a Kamaz truck has the same efficency as ground building radar. Chinese source has stated background noise gets lowered 100 times basically seeing a .01m2 target from 400kms instead of 1m2. I really do not care as much as what GaAS or GaN equipment is on the Su-57 for the 1st stage but my only concern is the 2nd stage.

I do not feel like talking too much about this even though its available publicly. I had a normal thread created on one forum by just putting up news information than that thread got deleted along with my account. Same story happens to another forum and ironically the admin at that one forum also had an account on that forum browsing that thread along with the other admin that is in control of that forum than of course account deleted for news updates and that is excluding the abnormal behavior when just throwing news updates on missile projects. What I learned from this experience is that there is a likelihood to military related forums that certain administrative authority figures have government related jobs which would make alot of sense because military related forums attract military personnel which would mean some classified information can be spilled which is why they are on the watch. And I can say the same for users that are suspected with multiple accounts. So far this forum along with another forum seem pretty chill so for users out there including yourself stay safe. I am saying this because maybe your opinions are based on the fact that you might work for lockheed martin which is why you know so much about stealth without the need of a anechoic chamber but you just cant state RCS figure estimates on certain features because you might get in trouble.

First to point out,this is a forum and if you are finding it hard to digest someones opinion for the sake of your fanboysitic fantasies,go and find somewhere else to dance on the stupid beats.......the level of your talk,you certainly didnt visit any of the forum...these is not mine but USAF F104 veteran's "Bruce Gordon"opinion on Su57 stealth...only the idiots will go on believing on the bullshit that a prototype aircraft was going in the warzone,and like I said do you have any proof of that prototype firing anything,any Sukhoi statement as they are the developers.....use some brain and go on analysing through the first and the last prototype,apart from color scheme better manufacturing and partial coverup of the exposed engine,do you find any thing which is different,don't bring S70 here,it is not Su57.....Even with the eyes one can't see that engine is right behind the intakes,that sums up who is a troll and a fanboy ...cut the crap and tell where does Russia fabricates GaN based semiconductors....and which UHF radar is been used for the fire control fire purpose...Your cry on ROFAR is not new for many,GaN breakthrough happened in 90s and yet their are only few vendors who are able to make GaN MMIC.... Do chinese have an operational ROFAR ,if no then it is all speculation and claims as it suit for the posterboys....Their is a thing called scientific paper,books,and other related stuff on various aviation core,try reading that,that might help you to prevent rhetorics and might help you to counter something without labelling someone in the desperation....you certainly don't even know what you're quoting and talking......and meanwhile for now UHF band for fire control was the best.....

I think LM is already have a prototype for autonomous wingman. It was seen flying using F18 ... I can't recall but I've seen the video. LM is also working on there sixth gen fighter program. Leaked images have shown that it could be a tailless design, with control surface morphing when required.

The problem is none of the Jets have been thought to be designed for Area denial type missions. Chinese are using AD/CC strategy and for that you cannot send squadrons of jets in a highly contested airspace. For that loyal wingman would be much better equipped and will be in very large numbers. You can say at-least a squadron dedicated for ECCM, and active decoying.

Sixth gen jets would have a laser weapon pod or would be inside its IWB.

Ahh no you seem upset that I keep stating RCS reduction features with also the benefit of efficient maneuverability. Than you seem to be trusting a USAF pilot who has served in the vietnam war opinion for an adversary nation. Thats like trusting John McCain and we all know how that guy is saying some very positive stuff about Russia so your opinion is already easily discarded. Thats like asking a random Pakistani or Chinese soldier what they think about India on this thread. You do not even know that there are different Su-57 prototypes(go figure) with different features that have reduced RCS estimates on engines and IRST systems and that has also became quite apparent with your su-70 statement that I will address here later. I can bring up the Su-70 here because that is the loyal wingman of the Su-57 but of course U.S. fanboys have a tendency like yourself to go bring up different aircrafts like F-35s on this thread. 2014-2015 was the creation of the ROFAR radar with 3.5 years of testing, than further testing has to be done on an aircraft which they are pushing to be integrated in the mid-2020s the same god damn timeframe they announced new avionics(you cant be that dense I hope). Getting an avionics update with this upgrade can be done. The F-22 had a 3rd generation radar that was integrated to the aircraft in 1998 than had a 4th gen radar integrated in 2005 than 2 years after testing it became functional with the aircraft. And for some reason you like to believe that it is stuck with a 2009 radar with no replacements in 2022 with 2 years of additional testing. This is why no one can here can take you seriously like this next post for example.

Certainly it will not have that exposed and rounded nozzle in the production variant and all those antennas which are coming out of the body.....

I already addressed this to you this was their goal image and that the antenna was to be removed.

Look at the X-47A and X-47B even though its a cancelled project it has undergone changes in its design. And that is the other reason no one can take you that seriously because you do not think that they are capable of putting new designs and replacements and that they stick with original even though you have already been proven wrong constantly here. As a snake oil salesman your reputation has been hurt.

Once testing is down the defense industry will have to plan orders next which by that time there is already a full scale production of photonic integrated circuits. This is why ROFAR is already considered a candidate for that new avionics upgrade to be tested. KRET has claimed back in 2015 that GaAS and GaN is present in their EW systems but they seem more interested in the photonics field relating to this. Raytheon has shown interests back in 2018 so I am wondering what kind of radars will be on the F/A-XX program. For all we know they might present the radar in 2021, 2023 or 2025 MAKS airshow or they might want to keep the appearance classified like a propeller from their new submarines or the Zircon missile.

Also that same company can provide feature like this as another possibility.

A simple picture of the prototype of the radar doesn't require that much effort...still where is the picture...

 

[Neptune]

Cheers I know a counter is difficult to make than remembering the past...
I guess it requires no brainer to judge the size difference of the internal weapons bay of an aircraft which measures 15.7mts and an aircraft which measures over 20mts....

Firstly the SU-57 doesn’t have 15.7 meter weapons bay, that’s over 51 feet. Secondly. Is it the SU-57s fault now that it can store long range cruise missiles internally but the F-35 can’t. Notice how you are attacking the SU-57s better capabilities by making excuses for the F-35s short falls.

even in the front DAS cameras are well conformed within the body and don't appear as a seperate surfaces.......

Wrong, the DAS is a discontinuity. Which creates corner reflectors from obtuse angles as well as edge diffraction. Even rough flat surfaces create RCS spikes. Everything on an aircraft has a potential to be seen on radar depending on angles, range and frequency. A ground based radar is more likely to see a RCS ‘hot spot’ from the F-35 DAS then from the SU-57s IRST based on location of sensors.

EOTS by design itself is more stealthier than carrying a full fledged targetting part...it is by
design only stealthier by all sides as it's surface is faceted and will reflect the radar waves on the other direction than too the source itself.....what shame of a comparison...

The DAS probably has a smaller RCS but as I mentioned earlier it is a discontinuity that creates large corner reflectors. The DAS is also about 20x larger then the IRST found on the SU-57, size and location also plays a role and those are things that are not in the DAS favor. The most stealthy sensor is one that doesn’t exist.

"operational flight in Syria" , in the combat zone was flying in the combat zone,did it participated in the combat, what missile did it fire,do you have any data of that , propaganda doesn't actually needs to fire weapons....

“No initial clearance” who decides that? Did Russian pilots hijack the SU-57 and fly it to Syria, did they need your permission for clearance?

Your second question. The SU-57 launched an Kh-59MK2 cruise missile. The Russian Ministry of Defense released a short clip and if that is “propaganda” then the F-35 surpasses the SU-57 in propaganda by a factor of a million since there is very little information or even pictures of the SU-57 compared to the F-35.

Lol genius should have bring some good point than pointing the image is of first or last prototype,the intake design has not changed since it was conceptualized,the near production variant has the same intakes...and this how your partial serpentine is looking like,RAM is applied on the internal walls of the intake which degrades the radio waves to a small extent,no RAM or RAS ever makes a protruding surface stealthy..repeating again and again,radar blockers are restricted to the ideal flights and not at all angle of attack....

You can repeat all you want but you are wrong on almost everything you have claimed. Do you have evidence that radar block restrict “ideal flight” and “angle of attack” you don’t even know the design of the radar blockers or how boundary layer airflow, vortexes or levons effect airflow into the engine and at what speed, flight regime or altitude this happens at so how could you make such a clown statement?

It’s actually DSI intakes that are detrimental to performance and that is a fact. There is a reason most aircraft have movable intake ramps and not fixed DSI intakes and that is because variable I stakes can change the velocity of boundary airflow at different flight regimes. I have come to expect these types of statements from you, after all, in the past you claimed the Rafale RCS is similar to SU-57 despite the Rafale having no faceting, edge alignment, Spectra sensors bulging from all over the aircraft and no weapon a bays.

Tell you a fact bro,a superconductor based radar will be superior to all,ROFAR is a concept,the day Russians operationalize ROFAR that day only it will be worth to mention just like their aesa radar ....even the current Sukhoi 57 has GaA based electronics,they don't have any foundry to fabricate GaNs. Apg81 is moduler,front end will can be retrofitted with the new lighter GaN MMIC in the mid life upgrades or whenever USAF wants,at current stage APG81 is more than required...

Where did you get that egregious lie from, F-16.net? The following article is more then 3 years old:

The Ruselectronics holding of the State Corporation Rostec has started to produce gallium nitride (GaN) transistors for the creation of 5G communication networks and a new generation of radar systems. Prototypes of microwave devices have been tested as part of equipment for quadcopters, radio stations and airport location equipment, and are currently supplied to more than 20 enterprises for test operation. Transistors PP9137A have a high specific output power, wide matching band, high breakdown voltage “drain-source”. The output power of the devices is from 5 to 50 W, the power gain is from 9 to 13 dB, and the drain efficiency is at least 45% at a test frequency of 4 GHz and 2.9 GHz

This is the stupidest statement ever

The majority of weapons systems, even ones that have been out for years or decades are still highly secret. We still don’t have pictures of most of the B-2s avionics and it been around for decades. The X-37B is a mystery, spy satellites are almost never even allowed to be photographed. We still don’t even have pictures of SU-57 real cockpit.

The X-37B is a mystery, spy satellites are almost never even allowed to be photographed. We still don’t even have pictures of SU-57 real cockpit.

You messed up things pretty badly,with 15.7 mts thing,it is the length of the f35,Su57 is way bigger thus it has provision to keep bigger weapon bays.........it's doesn't take much to produce picture of what you claim,enough of this we don't have bullshit...

No, you messed up pretty badly that’s why you are quite now. Don’t speak of topics that you know nothing about such as RCS, Russia not having GaN technology. It is also absurd of you to make demands and statements such as brushing aside and refusing to believe countless sources, including from Russian defense manufacturers and instead demanding pictures of highly classified prototype designs to prove their existence.

Again who is messing up and bullshiting? I countered everything you said and I have much more I could have posted.

So all those sources are lies? So you want @panzerfeist1 to post classified prototype avionics? Why don’t you do a James Bond and show everyone X-37B avionics too while we are at it


After your blunders/lies about Russia not having GaN, claims about SU-57 not firing weapons in Syria, claims about the DAS being “stealthy” you should have just graciously exited the thread instead you doubled down and started insulting and mocking and now you want classified pictures to satisfy your ego. Everything you have claimed has been be-bunked with sources.
