Another! I like the change. Very sleek!
That particular picture is probably fake. The new prototype should be marked 2051 among a few other things.
you are just a mouth piece of Lockheed Martin and a fan of J-20.At this point this is tantamount to climate denial mate. You're fighting a strawman. No one said stealth aircraft were invisible. F22, F35, Su57, J20, J35, B2 and future NGAD, B21 and H20 are all detectable.
The issue isn't detection, it's producing target tracks. Even in the Longwave frequencies Nebo searches at, it cannot produce a target track on legacy B2s let alone the upcoming B21 and NGAD.
F22, F35, Su57 and J20 can be tracked at long range via low frequency band radars, but developing a weapons track, even with AESAs requires distances well in range of current stealth fighter weapons engangement ranges. All those active radar systems are detectable and targetable from a stealth platform.
In air to air or air to ground.
F35 and F22 are prototyping new radar absorbing materials magnitudes better than current coatings in rcs and IR minimisation and durability.
You also discuss these issues ignoring MISSION PLANNING.
Ukraine rocking Russian positions in strategic location recently is mostly a credit to NATO (Mostly US and UK) SAR and mission planning. If they can provide such accurate targeting data to a third party for a proxy war, take into account the surveillance capabilities, both airborne and space based, that would be available in an actual confrontation with Russia or China.
With Stealth fighter aircraft in theater; integrated with space based assets and VLO UAVs and Bombers; legacy radars like Nebo are large, sitting ducks lacking all weather mobility off-road.
This is true for large ground based surveilance radars in the PLA. Which is why PLAAF is investing in a stealth fighter, surveilance and communication ecosystem of its own.; also integrated with ground based and AEW&C surveilance platforms to counter US, Five Eyes, NATO, whatever alliances.
Russian narratives of stealth are self soothing at this point. There is a reason Su57 programme was initiated. But the fiscal investment needed for PRODUCTION at relevant numbers vis-a-vis NATO is lacking for the RuAF.
Which is why we get these stories about how useless stealth is. They can't afford large scale manufacturing of Su57. Especially with the Ukraine War raging and frontline military resources dwindling.
RuAFs best bet is rapid testing and development of integrated Su57 and VLO versions of the Sukhoi UCAV plus associated low signature communications networks necessary for air dominance surveilance and strike in A2G and A2A.
But they don't have the funding.
This Nebo or A50 fantasy is air. They don't exist in enough numbers to persist on a conflict with NATO. Less than a 200 systems vs hundreds of F35s alone. A force that provides additional targeting data for Air to ground, surface to surface and sub/shipborne LACM fire.
Firstly, the most important part of the chart which I wanted to show you is actually how thurst will change depend on altitude (air density).pure fantasy your chart is based upon speed and thrust but it does not give you warload and fuel, because range will also play a part, you use the chart and automatically give data what you think it will be the range of detection.
Aircraft need to carry fuel carry weapons plus you give F100 so basically you give unrelated data and later give assumptions not supported by your chart.
Just I give you a simple data
Power Plant: One Pratt & Whitney F135-PW-100 turbofan engine
Thrust: 43,000 pounds
Maximum Takeoff Weight: 70,000 pound class
F-35A Lightning II
The F-35A is the U.S. Air Force’s latest fifth-generation fighter. The F-35A will provide next-generation stealth, enhanced situational awareness, and reduced vulnerability for the United States andwww.af.mil
Maximum Takeoff Weight 31751.466kg so tell me at what is the thrust to weight ratio very very low in fact the F-35 not even at empty weigh achieves a good thrust to weight ratio, so you fantasize a F-35 to carry weapons needs more than 12000kgf to achieve good performance so you are dreaming
you are just fantasizingFirstly, the most important part of the chart which I wanted to show you is actually how thurst will change depend on altitude (air density).
Secondly, it doesn’t matter if the chart I gave you is for F-100 or F-110, in fact even if I gave you the chart for AL-31, it would still illustrate the point I was making very well. The point is “thrust of air breathing engine will change depend on altitude because altitude affect air density”, whether your aircraft run on F-110, F-100 or F-135 then that fact is still the same.
Thirdly, max take off weight of F-35 is the condition where the aircraft use both internal and external station , basically the heaviest I can carry and still lift off from the ground. It is a massive different from the condition only with internal Air to air missile
Once again, you resort to the tactic of using strawman argument. No one here ever said stealth is invisible. No one here ever said RCS is a fixed value at all direction. In fact, we even explained to you that the purpose of stealth is to reduce enemy detection range and engage them before they can do the opposite. The simulation I posted earlier actually illustrate that very well, it not only show the different of RCS depend on direction but also frequency. So to be frank, I’m not sure what you are trying to achieve here?. Do you somehow hope that if you repeat your strawman argument enough, then people will suddenly lose the ability to read and believe whatever you say?pure fantasy, there is a law in physics matter does not disappear or is created only is transformed.
Stealth aircraft only reflect a great part of the radar energy in other directions, but that is also wave length dependant, since F-22 is highly dependant upon shaping, it limits is modifications and variants, basically is very limited to growth, so it is better retire it.
if you think RCS is fixed is pretty a myth
Let me guess, your simple brain probably think that based on that formular, the bigger the wavelength, the longer the detection range will be. And therefore you just need to increase the wavelength to improve the detection range significantly? Well unfortunately, wavelength also tie to radar gain, the longer the wavelength, the lower your radar gain will be with any given aperture area. Lower gain will expand your beamwidth, which not only reduce radar accuracy but also reduce the power concentration, and as a result, the detection range will reduced accordingly. That the reason why low frequency radar are all super massiveView attachment 187008
the formula stated different wave lengths give you different detection range, plus different transmitting power will give you different detection range too.
Sure A-50/A-100 will detect a F-35 or J-20 from further distance compared to what Su-57 or Su-35 can achieve. But guess what, A-50/A-100 both have RCS of a barn door and with the agility of a road roller, good luck keeping them survive against long range missile like Meteor or PL-15have you ever thought AWACs will detect the F-35 farther than Su-35?

So I will put it simple, nothing is invisible or stealth, energy is never destroyed or created and as a Russian A-100 crew said, we see stealth there is no stealth aircraft
Firstly, you don’t need T/W > 1 to cruise or even to engage in BVR combat. F-14/Mig-31/Mig-25 for example, has T/W much lower than 1 and they can do BVR combat just fine. You don’t actually need high T/W to fly fast , top speed of aircraft is limited by ( dynamic thrust-drag). And you don’t even need to fly very fast to engage target from BVR eigher, F-15 shoot down plently of aircraft from BVR, yet, it rarely accelerate past Mach 1.4 operationallyyou are just fantasizing
12000kgf is not even the empty weight of F-35, the fighter is very heavy and fat, it was designed to be slow
The F-35 in order to fly with weapons needs higher power settings and in average take off weight is heavy.
On average F-35 was designed as a BVR fighter and it was designed to fly in numbers, however it is not the super fighter is claimed, its jet engine is hot.
So regardless of your fantasies, the fighter needs to stay far from the enemy, relies of helmet mounted sights to replace its lack of agility, and as a fighter needs to fly slow, with very few missiles.
It is a mediocre fighter you like it or not

Physically long waves were used in WWII and the effect on the Luftwaffe was pretty bad.
Radar range depends on wavelength, line of sight, and the transmitter power, as well as the sensitivity of the receiver electronics. Radio waves with a wavelength of about 500 cm (15 feet) or more are reflected by the earth's ionosphere (upper atmosphere) and can reach to great distances. Radio waves at shorter wavelengths are not reflected by the ionosphere and are unable to detect objects below the horizon. This means that most radar antennas are best located as high as possible
Wavelength. The wavelength was an important indicator of a radar's capability. Much of the Allied superiority in radar lay in the use of the cavity magnetron, which allowed the Allies to exploit the capabilities of centimeter-wave radar. The shorter wavelengths permitted much better resolution. However, meter-wave radar had the advantage that it was able to look over the horizon, so these radars did not disappear from the Allied inventory.
Power. This is the average transmitted power. The greater the power, the greater the sensitivity of the radar. Peak power is roughly equal to the average power multiplied by the ratio of pulse width to pulse repetition frequency.
your analysis is so poor that a 4 year old can do a better one.If only Lockheed Martin found my random musings on an Indian Forum worthy of consultancy fees
Russian Airforce inability to establish air dominance over Ukraine is evidence enough..
Stealth is a necessity, even against a non peer level opponent. If it could be done, the 4th gen fighters and fighter Bombers in the RuAF like Su35, 34 and associated long range Bombers would have established air superiority over Ukraine by now.
But they have failed, because they would need to have invested billions in stealth aircraft procurement to levels enabling penetrative and dominance of contested airspace.
Russia does NOT have air superiority over Ukraine.your analysis is so poor that a 4 year old can do a better one.
Russia has stablished air superiority. however the West is constantly supplying Ukraine with weapons, basically Ukraine is a NATO member, for Russia to stop the west needs to go to war against the West.
Your level of analysis well does not go beyond CNN.
This is even a Lesson for China, will Russia win the war? yes they have already won it, and Su-35 dominates over any Ukrainian fighter, I guess you believe fairy tales of ghost of Kiev or you have pictures of the many many Su-35 downed.
However fools think Russia has not stablished air superiority, because they do not consider the west is supplying weapons and forget there is no NATO aircraft allowed to fight Russian aircraft in Ukraine.
Basically Russia controls the air space of Ukraine but NATO send weapons to replenish for losses for a reason Ukraine ask fighters but NATO only sends spare parts but no western fighters, so you Chinese we know you hate Russia and covet Siberia, you have hate and hypocrisy for Russia, you are no friends of Russia, but the west knows it and will use you and you will lose and will come a time Russia will ally to the west to fight China
This guy is getting obsurd ... It's more ridiculous than his "max 40 J20" theory and prediction on 2020 that "China will buy 24 Su35 in 2016..."so you Chinese we know you hate Russia and covet Siberia, you have hate and hypocrisy for Russia, you are no friends of Russia, but the west knows it and will use you and you will lose and will come a time Russia will ally to the west to fight China
India media on RuAF:Russia does NOT have air superiority over Ukraine.
S300 and Buk in Ukraine are keeping Su35 and all other RuAF jets at bay.
Russia is relying on standoff missile and drone strikes.
The RuAF sorties within Ukraine are limited to LO-LO-LO flight profiles at cost to persistence and weapons release velocity. The service's large wing ISR assets can only operate at standoff ranges. Regular operations in theater at high altitude are off the table due to the SAM threat.
Stealth is a necessity for air dominance vis-a-vis a near peer military.
The other stuff about Russia allying with the West?... to fight China?...
Even more ridiculous than your claim that Stealth is unnecessary - citing the same "low cost" Russian Airforce ethos being trounsed in Ukraine.
Not going to waste time on it. Obvious to anyone that Russia isn't allying with the West within our lifetime.
Get back on topic mate.
Coming to this pic which you have shared here.@StealthFlanker
One question, the surface treatment of Su57 received many criticism on Chinese cyber, they thought it reflects Russia's flagging industrial capability, and would serious damage its stealth effort.
How do you think about it and dose it affect your simulation? Please advice.

Generally speaking, Su-57 is still in prototype stage with very few sample. So details such as edge treatment, surface treatment may not get enough attention yet. Obviously the discontinuity such as those on your photo will increase aircraft RCS due to edge and surface scattering. But at the moment, it might be unfair to assume that those surface imperfection will carry on to the production version@StealthFlanker

And that where stealth come in. You can't avoid something that you can't detect. And by the time your radar detect a stealth aircraft, chance are several missiles already heading toward your directionDo you understand that the faster the target the lower the chances to intercept it?
Do you know MiG-25s avoided F-15s thanks to speed?
That is the dumbest analysis I have ever read, everyone in this thread now are dumber just for reading your so called "analysis"Your fantasy goes to think F-35 uses low thrust and has excellent performance.
Let us see the aerodynamics of low drag aerodynamic bodies
the F-16XL was a really low drag aircraft, F-35 is fat, get it thus it is slow.
it is heavy and has a very large internal volume, and a large cross section thus it carries few missiles, you overestimate the aircraft.
and same applies to J-20.
Low drag fuselages are F-104 or MiG-21, but F-35 is fat and has a blunt radome.
View attachment 187097
see F-104 has a much thinner slender radome
View attachment 187096
Yes, and both A-100 and Su-35 will eat dozen of AAM to the face before they get close enough to detect stealth aircraftA-100 will detected it and Su-35 has different radars and IR systems.
you are really pretending to know.And that where stealth come in. You can't avoid something that you can't detect. And by the time your radar detect a stealth aircraft, chance are several missiles already heading toward your direction

Whether a modern jet fighter is fast or slow has very little to do with their nose shape
For example, F-14 and F-4E both have pretty fat nose and yet they have much higher top speed than F-16XL and F-104
View attachment 187266
View attachment 187267
The primary thing which determine an aircraft top speed nowadays is the inlet, as it affected the dynamic thrust value at high speed. However, top speed is rarely important anymore since aircraft doesn't really have time to accelerate to top speed before they launch their missiles, and they can't cruise at top speed all the time either

Back to actual J20 news, what looks like high-speed taxi teats of the new 2051 prototype, likely a new J20B variant.In fact the only thing that makes stealth work is not shaping but this
View attachment 187289
so there is loses by increasing the distance so a relatively weak radar will be fooled by shaping and faceting, but not very powerful radars, in that you are wrong stealth aircraft will not get that close, their radars are weaker than AWACS.

State media said that this radar can detect airborne targets out to 600 km, and ships out to 400 km.
State media also claimed several times that thanks to this radar the aircraft will be able to detect U.S. F-22 and F-35 Stealth Fighters.
