It does appear funny when landing gear collapses of world's costliest fighter jet.

Same kind of problem with a far more costlier aircraft : B2It does appear funny when landing gear collapses of world's costliest fighter jet.
US citizens must be very angry on usage of their taxes, but the engineers are also frustrated.
There is simply not enough data.How stealthy AMCA going to be seeing it's design and size? Will it be anywhere close to f35 or f22?

Obviously that's the theory of upgrade but just like don't rapidly upgrade our phone, laptop, washing machine, TV, etc when every year there are newer better models, similarly military systems also cannot be rapidly upgraded until the 1st iteration of the PROJECT is complete otherwise there will be significant surge in cost affecting country's economy.
I'm common citizen, not DoD person. This is casual unofficial hobby site for enthusiasts who's basis are the public media sources. But atleast i'm technically qualified & experienced.
What would be your basis? Are you DoD guy?
I respect your belief but that's not what i believe, so let's not go in circles of dogfight of words. I did say that Su-57 is dangerous in close combat & it has some cool things like DIRCM, LEVCONS, 3D-TVC, etc which is yet to be seen on western jets but at the moment i believe that F-22 is better in BVR, that's all. So everything has plus & minus points, strengths & weaknesses, simple.
People like Mr. Hostage are in perfect position to take hostage of public's mind & opinions.
So nobody is stopping Russians to post a similar video demonstrating the OLS-50m which is larger than AN/AAQ-37. The public will believe what will be shown, simple. I'm an engineer, i'm on side of technology, not on side of Russia or USA. Technical people will tell u plus & minus points while non-tech people seem to take sides sentimentally just bcoz a country supplied arms since decades, LOL!
We are able to see the stars & sun only bcoz they release enough photonic energy to travel in vaccum without particle scattering. Inside the atmosphere it is a different story.
And there is something called aperture size, focal length in analog optics.
In digital optics, the focal plane sensor material matters like PbS, InSb, etc.

Whether the sensor is for LWIR, MWIR, SWIR, that matters as there will be different image created for same object.
View attachment 23025
The sensor is IR or UV based that matters.
The altitude of source & target also matter.
then the quantization rate matters, the software capability matters.
View attachment 23027
All these things decide the cost of the system. Just google the price of best DSLR cams, movie cams, telecasting cams. See videos how lenses & cameras are made.
Who doesn't wanna show-off? The Russians don't show-off? You don't see their documentaries it seems. The F-35's BMD video showed digital image processing in engineering mode & u said it right "most fighter IRSTs tend to discard it as clutter" bcoz their software engineers are more ignorant in programming. If our classmate went to IIT & we lagged behind whose fault is it? In my college 3rd year i made a project using DIP so i know what i'm saying.
If the F-35 can help in any way to share a target data, what's wrong in it? Is it a problem or a solution? Do you even know how software solutions work?
You have wonderful data on cost & procurements. Rich people are everywhere, we all have read about Russian Czars.
But Russia, a frozen popsicle country is having vast experience being weapon mongers since the WW era & India being a tropical country has vast experience in getting used, import dependency, corrupt govt. officials, citizens challenging eachother, inter-state racism, etc
India has lots of potential, global CEOs but all running after dollars, pounds, euros
India has lots of money but in secret accounts of corrupt people.
We Indians after 7 decades of independence talk of democracy & can't overthrow a monarch family
Israel, another tiny heat-scortched desert country, surrounded by enemies has survived well.
No, technically i'm talking about how many Lumens of photonic energy is reaching the sensor from what distance, what type of sensor it is & whether the combo of H/w & S/w intelligently tracks it, classifies it & then decides to ignore it or straight away irgones it as clutter.
Bigger source will be detected at larger distance, smaller source will be detected at smaller distance.
So if BM's plume is detected from 1300Km in 10x digital zoom then a jet's plume could be detected in range of say 300-500Km easily, but it depends on so many technical & environmental factors i mentioned. And the Russians are yet to share their demo.
BTW if gas stove sized thruster lit up in vaccum of space then it would be equally easily picked up as any other big source as long as the photonic energy reaches the sensor, same way as we can see a star light years away.
I don't trust either of them for different reasons
How stealthy AMCA going to be seeing it's design and size? Will it be anywhere close to f35 or f22?

So are you DoD guy who is claiming to know the facts? What are your sources, credibility, qualification?Regardless of what your experience is, data is generated based on facts, not because you feel like it.
3rd time let me ask u - are you DoD guy who is claiming to know the facts? What are your sources, credibility, qualification?Yes, but no one else has data. No one is publishing it either. So why rely on unofficial sources with disreputable data?
So why the data about Russia is unknown? Since cold war days USA & Russia have competed in military tech. Fortunately USA got bigger better R&D ecosystem with allies, more than Russia, that's it. But i did appreciate aptitude & attitude of Russians.That's what I'm also saying. But you are comparing some known data about the F-35 with completely unknown data about Russia and deciding by yourself that Russia is inferior based on data about pretty old previous generation technology. That's very disingenuous.
LOL! When did i say that HAL/IAF doesn't know what they are doing with FGFA? It is good they realized & pulled out of PAKFA. I already told u that a techie like me doesn't take sides of country, products, people & neither will a techie woring in DRDO, HAL, etc but they are under oath & orders to keep quiet not to reveal any loopholes.You are basically showing the HAL and IAF in poor light. Like they didn't know what they are doing with FGFA.
" ability to network and use offboard systems" means all the H/w & S/w integration which i explained. Every component matters.As for the F-35's IR capabilities, it's more about the F-35's ability to network and use offboard systems that allows it to use IR detectors in various ways, it has nothing to do with the IR detector itself. It can do the same with OLS-35 with the right software.
Selling product depends on demonstration. People even do MBA for that.The Russians are yet to "demonstrate", but they don't do such things. For the US, the F-35 is an export-grade program. For the Russians, the Su-57, at least their version, is not. And even data about their export grade stuff is not easily available. We will have to wait years for it. Post which there will be questions of authenticity.
What does "sucks" mean, i don't use such slangs.But you've already decided on your own that Russian tech sucks by default. At least we know the basic capabilities of the Su-57 are far above that of the F-22's, again, as per the USAF themselves.
Is this a complain lodging forum for DoD?It's the same reason why I entered the forum back in 2013, people were comparing things (EF vs Rafale) without any real data on it. Only tenders and exercises could actually give us the minimum data necessary to come to a conclusion. Now you are repeating the same with US and Russia.
"hearsay"? 4th time i'm asking u - are u DoD? What is your source, credibility, qualification? Random Guy as Radio Jockey? Please forgive me, i have patience limit & self-respect too.You want to talk about the F-35, great, knock yourself out, I support it. You want to speculate about Russia, go right ahead, I do the same. But you wanna compare two systems based on hearsay, you can see why it is easily challenged.
You literally compare apples and oranges and expect people to take you seriously? Yeah, some people will fall for it. Not me.
Why should i give a damn if American E-3 can detect Chinese J-20?E-3 is unable to detect the J-20 because photons are unable to reach it. Shouldn't that get your gears moving? In a world bereft of data, observation is key. Blanket statements get discarded easily.
So are you DoD guy who is claiming to know the facts? What are your sources, credibility, qualification?
If other's experience & qualification is not valid for u then why should others listen to your RANDOM RADIO?
You seem to be a non-tech guy unable to explain technical things technically hence disregarding my knowledge & experience.
Do you go to doctor's clinic, bank, court, shops, etc & tell them this same statement?
3rd time let me ask u - are you DoD guy who is claiming to know the facts? What are your sources, credibility, qualification?
This is an unofficial hobby forum for common citizens, what do you expect?
The top military people also have to be tactical, diplomatic as per geopolitical situations.
So why the data about Russia is unknown? Since cold war days USA & Russia have competed in military tech. Fortunately USA got bigger better R&D ecosystem with allies, more than Russia, that's it. But i did appreciate aptitude & attitude of Russians.
And if you can favor Russia, Su-57, that's also deciding by yourself without disclosing your profile & sources, your choice & belief, i don't have any issues with that. But you don't know formal communication with strangers.
You don't introduce yourself,
You don't use any pictures, diagrams, etc to explain technical things,
You directly discredit others experience, knowledge after after they have tried their best to explain things conceptually
then you use insulting words like this, YOU ARE INSULTING & DISCREDITING YOURSELF. IF THIS WAS F2F DISCUSSION, YOU WOULD HAVE BEEN SHOWN THE DOOR BY NOW.

To a common tax payer citizen the internal structure of DoD doesn't matter - HAL, DRDO, NAL, ADA, who does what exactly. In parliament of every country including USA, questions are asked on timely development of assets & wise utilization of funds. Whenever F-22, B-2, F-117, F-35 crashed, questions were asked by representatives of citizens. Do you want to totalitarian/autocratic/communist regime not answerable to public?
And HAL, IAF, etc are in fact in a poor light crisis, entire world knows about our depleted squads, delayed projects, scams like Bofors, Rafale, etc.
" ability to network and use offboard systems" means all the H/w & S/w integration which i explained. Every component matters.
" nothing to do with the IR detector itself. " - You just discredited all the R&D after AN/AAQ-37 DAS & AN/AAQ-40 EOTS
"It can do the same with OLS-35 with the right software" - So tell the Russians to use their computer programming skills & demonstrate publicly, who's stopping them?
Whatever i explained with pictures bounced off your head. This is how non-techies are arrogant but they occupy management positions, create bad leadership & country suffers.
Selling product depends on demonstration. People even do MBA for that.
"their version" - the domestic version is obviously superior than export version. What are you talking?
We don't have luxury to wait for years looking at possibility of 2 front war.
What does "sucks" mean, i don't use such slangs.
BTW if u support Russian tech & J-20 so much then explain why did we choose GE414 for MWF, AMCA, TEDBF when we already make AL-31 for MKI & China used AL-31 for their J-10, JF-17, J-20 & so did Russia for all current jets till Su-57 & even for UCAV S-70.
Every member of an unofficial forum decides their belief & none of us have to give an official public speech. It is like different people like different cars, phones, laptops, etc. But people like you wanna accuse & fight with someone just bcoz they didn't prefer a product which u chose
I did give credit to both F-22 & Su-37 in BVR & dogfight respectively. Rest, time will tell, but if time would tell then it would mean huge war b/w Russia & USA, perhaps world war.
Whatever documentaries & even news i have watched in last 25 years since 1990s, both USA & Russia have praised eachother's products & criticized too claiming their product is better. Sometimes the statements are diplomatic, sometimes tactical.
They did joint excercises with F-15 & Su-27 but today they can't do it with F-22 & Su-57, but F-22 Vs Rafale & others too perhaps was done.
View attachment 23042
Is this a complain lodging forum for DoD?
You entered this forum in 2013 as some kind of savior to educate complaining people?
The data from tenders & excecises are published publicly but the public opinion on procurements & own R&D is always divided.
For example, when we did Ex Indradhanush with UK, they praised our Su-30MKI, we praised their EF-2000, but there have been hot debates too.
"you are repeating...." - i didn't invite you to reply to me, nor do i reply to everybody, and I REPLY TECHNICALLY NOT PERSONALLY WHICH U DIDN'T LEARN SINCE 2013 IN 9+ YEARS.
"hearsay"? 4th time i'm asking u - are u DoD? What is your source, credibility, qualification? Random Guy as Radio Jockey? Please forgive me, i have patience limit & self-respect too.
Unofficial hobby forums are not meant to challenge eachother. People have their opinions, may disagree, then walk away.
If you choose a particular car/phone/laptop, do you accuse & fight with others if they choose something else?
Why are you the only member who is taking me seriously & accusing me & fighting? Don't fall for me? Walk away with your opinion.
DoD won't consult me or you either ever, unless u r part of DoD.
BTW, we all consumes both apples & oranges without comparison Yummy!
And our DoD is also consuming Russian, American, French, Israeli, etc stuff - apples, oranges, grapes, bananna, etc, there also public opinion is divided.
Why should i give a damn if American E-3 can detect Chinese J-20?
Mr. Hostage has taken your observation as hostage perhaps.
Why r u so pro-J-20 & defending it? Are you *censored* or pro-*censored*?
"Don't take what I said personally. Your posts simply didn't show an unbiased opinion to me, so I challenged your assertions."
Thanks for accepting that your intention is to challenge others in an unofficial hobby forum. That's immatured & offensive behavior If u r non-techie &/or don't use ilustrations for discussion, then not others' fault.
And i did show Unbiased opinion -
when supporting F-22 & Su-57 in BVR & dogfight respectively
when sharing data about both OLS & AN/AAQ sensors
when showing illustration of effect of Russian IRST
when praising Su-57 for items which western jets don't have yet
when i asked u if u watch Russian documentaries or not, which i sincerely watch like RT, Combat-Approved, Wings of Russia, etc, that too since 1990s. From your replies it seems u were not even born or were a toddler in 1990s.
If someone will insult me, i will take it personally but everybody can see who is twisting the words.Yeah, you took it personally. Best part, I'm not offended by anything you said because I knew you would reply this way. It's a typical behaviour of people who think they know everything. All I did was ask you to use actual data instead of making blanket statements, and look at the quality of your replies.
Yes i'm fanboy bcoz this is fan-site And i'm fan of F-22 since 1995 when we got color-TV & cable-TV arrived in our colony & Discovery channel used to telecast WINGS program. What were u in 1995 - unborn, toddler? Can't help if someone has a problem with F-22.No, you didn't post anything that's unbiased. You immediately came off as a fanboy pretending to be unbiased. There are plenty of experts on the Internet who pretend to be unbiased but are actually very, very biased, perhaps even unconsciously, but they are.
Example:
when supporting F-22 & Su-57 in BVR & dogfight respectively
Oh! i didn't know every member must take tution classes from you before writing anything here in UNBIASED wayNo, that's a biased opinion. Why? Because even the F-22 and Su-57 pilots cannot tell who will win unless they actually fight. What you have done is used Western stereotypes to give the Su-57 the advantage in dog fights and the F-22 in BVR. I don't even know where such a ridiculous notion came from. You've basically dismissed the F-22's ability to dog fight and the Su-57's ability to lead BVR simply based on a whim. That's not how the world works. There is quite literally no basis to have such an opinion if you consider yourself an expert. The real answer is "I don't know". But that's too hard for you to say. Plus you haven't even considered the other possibilities, the Su-57 could win both, the F-22 could win both, or the opposite of what you claimed, where the Su-57 wins BVR and the F-22 wins dog fight. So what kind of information do you have that you can 100% come to the conclusion that only the possibility you presented is true? My answer is I have no frigging clue. That's being unbiased.
If u hav clue & data then pls presentSimilarly, when you say the F-35 has better electronics, better DAS etc... Again, no, you have no clue at all. You have zero data to come to such a conclusion. You are just making claims and not even presenting it as your personal speculations.
My technical qualification is my technical logic for a technical topic. People like me only work in ADA, DRDO, HAL, etc. My college senior worked on LCA for few years. So u don't lecture me, look at ur own qualification, logic 1st.And, no, you don't need to be an expert on anything to know you can't have an opinion without actually having any data. You can speculate, you can give your reasons, use logic, but instead you decided to claim the F-22 and F-35 have something and then decided the others have none of that simply based on a whim. That is not what "experts" do.
OMG, see u r still so big defensive fan of Su-57 with which i don't have any issues but u hav problem if i'm fanboy of F-22What if I tell you the radar, IRST, OLS, weapons and EW suite (all bigger and better, with the latest hardware) on the Su-57 are a generation ahead of anything that's present on the F-22 and F-35 today? Wouldn't you ask me for proof or data? Or would you react the way you just did?
Whether the technology is old or new, ultimately what matters publicly is the quoting of specifications & demo if possible.Just so you know the Americans had developed Kalman filter based IR trackers that could detect, track and cue lasers on to BMs back in the 80s as part of the SDI. It could even use the longitudinal oscillations of the plume against the body to improve track. So it's nothing really special today. Also the F-35 DAS's range isn't particularly exceptional because the technology is already old compared to today's standards. For example, the EOTS was 10+ years behind competitors even before IOC. Pretty much all of the F-35's IR sensors require upgrades to new designs. It's part of their plan to replace such hardware every 6 years, but that's been ruined due to development issues.
If we can replace older radars by our UTTAM then u think other countries won't have MLU?Similarly their radar and EW suite are also designs from early 2000s, finalised only by the late 2000s. I'm basically saying the F-35's hardware has been operationally outdated for the last 5 years, and in labs it's over 10 years. Which is why the Pentagon is planning a hardware refresh by 2027, and they are in a hurry. You will be more impressed by what's on the Gripen E once info is released. The new MAW-300/PAWS-2 combo is way more advanced than what's on the F-35. MKI's planned DCMAWS was also half a generation ahead compared to the F-35's, too bad it didn't work out then.
So u only have given proof now how bad is situation for IAF/HAL , you can't accuse others of putting IAF/HAl in bad light or claiming & concluding something illogically. And still u didn't tell us if u r student, professor, journalist, DoD, spyIn the military, it's pretty much taken for granted that everybody buys or steals technology to get to where they want, especially so when electronics development is largely led by civilians, so it's taken for granted that pretty much everybody has similar hardware. Most of the differences come from system design and software. So it's all about the speed at which you operationally deploy technology that matters more, which is why the Chinese perform hardware refreshes every 5+ years, the fastest in the world. The J-10s have finished going through three, with the fourth in progress, the J-11 family has finished going through four. The Rafale is in its second refresh. The MKI is yet to go through its 1st one.

- able to introduce himself
- expert in formal communication & avoiding huge paragraphs of psychological comments
- able to use lots of technical illustrations, diagrams, high level knowledge like seen in engineering colleges
- ideally should not exist on unofficial forums, grabbing attention, leaking something accidentally
Like i mentioned, i had a college senior who worked on LCA in mid-2000s, told us some good generic stuff nothing secret. So i can easily make out who is genuine techie & who is just wasting time.
He is afraid to introduce himself, but thanks for the information.Well you ought to post your questions directly to him . I've informed you of what I know.

I won't ask for proof bcoz we are common citizens incapable of arranging real proof unless we are spy like James Bond 007.
On a fan site all we can do is give links, illustrations, diagrams from online media. U & others can count how many u & i have given.
Whether the technology is old or new, ultimately what matters publicly is the quoting of specifications & demo if possible.
As per public data online the OLS sensors are quoted at less than 50/100 Kms when approaching/chasing target. While F-35 videos on YouTube shows higher range. So what do you expect the public to do - arrange proof further, use logic further?
During the cold-war days USA had SDI program benefiting EO sensors, Russia also did whatever they could but they are yet to give any public demo yet. In Russian documentaries they have shown SOAR & SOLO sensors "just kept on the table" rather than giving a DAS like demo, what do u expect from public - again arrange proof, use logic?
If we can replace older radars by our UTTAM then u think other countries won't have MLU?
Trust me i'm not some personal West/USA fan, i'm a techie, i'm tech fan. But USA is always in a hurry for everything bcoz they are management oriented people. They understood after World War itself that to lead the world they have to lead in as many tech areas as possible - aviation, defence, automobiles, computers & electronics, commercial & consumer goods, even food industry like McDonalds, Starbucks, etc. Most of the top universities are in USA. Most H/w & S/w companies are from USA. Internet (by DARPA), microchips (Intel, AMD), OS(Windows) are from USA. Indian IT industry mostly caters to USA & other western countries.
This website is also hosted on a server in San-Francisco & not in Moscow or Beijing u know that?
Where is Russian stuff in how much quantity at our home & industry?
Russia wanted base as India & USA wanted base as Pakistan during cold war, that's it. Russia, France, USA, EU, Israel, etc have sold arms to both sides of border. Every country has their own intrests to run their economy.
I will be very happy if something can defeat F-35 EOTS & DAS bcoz that's natural evolution & competition. Nothing stays on top forever. F-35's AN/AAQ-37 DAS & AN/AAQ-40 EOTS were developed in 1990s & MAW-300/PAWS-2 & DC-MAWS have been developed in last decade, 20 years later. What comparison are you doing? Obviously the F-35 will require some upgrade to stay ahead. And to stay ahead of world they are on track not just to upgrade their sensors but to build another new jet of next gen, that's the bigger picture to notice. And we are still struggling at sub-systems level.
But the truth is that 1st the F-22 & then F-35 used the 6-axis MAWS then Russia implemented it exactly on those positions in Su-57 & Su-35, then China did it on J-20 & now we may do it in AMCA & other jets. If Russian tech is so good then why IAF/HAL are today still struggling for MAWS & not implementing SOAR & SOLO sensors like on Su-35-S & save time?
View attachment 23055
J-20's EOTS is also on chin, AMCA's EOTS will also be on chin.
Why did they consult Russia for DC-MAWS locations when Su-30MKM applied MAW-300 timely? And now news says 12 more MKIs on order.
