See, J-20 is just a copy of American F-22.





China has always reverse engineered the outside technologies.

Now coming to the point, that why India is not afraid of this aircraft, I will put some points here.

1 Why would any country will put any order of other foreign aircraft, if it has its own advanced aircraft??? Yes, the chinese has put an order of Russian Su-35. Because they know that they are unable to meet there specifications in J-20.

Well they claim to detect stealth aircraft, but there radars are not very good. Hence they plan to buy 4 Russians Su 35.

2 Well this aircraft is in its low rate initial production. Till they will introduced it in PLAAF the Russian Indian FGFA will also be ready for its induction in IAF (maximum 6 months later after J 20).

Now you think, if China are so eager for Su- 35, how advanced will FGFA be, which both Russia and India will not share with anyone.






现在你想想,如果中国如此渴望苏- 35战机,那么第五代战斗机会有多先进,俄罗斯和印度是不会与别人分享的。

3 Now if you are thinking they will pass this technology to Pakistan, then forget about this. Firstly it is strictly not for export (same as F-22, no one will share there latest technology). Now coming to pakistan, can they afford to buy it!!! Year before they do not go ahead to buy F-16 for $700 million.

And do you actually think China consider pakistan as its ally?? They are just using it for there purpose, and there increasing economy.

4 India is in very few countries that have nuclear triad ie they can attack from land, sea and air. And moreover India’s Missile defence system is ranked among top nations (for ex: as most of the answer here mention S-400 Triumph).

5 India always have support of Russia. And now at this time, most country have dispute with China. Vietnam, Japan, US and NATO countries clearly do not like him and will engage in war if they dare to atrack India.

So China will never think to attack India, after looking to our military power. There increasing economy cannt afford any war.

India has never invaded any country first, but if some one will try, we wont tolerate it. And China must know it, that we are always ready for there freindhip proposal.

Fact is India is not afraid because of the way Chinese stealth fighters - like all stealth fighters and other air crafts, are configured.

One thing U.S. and European fighter craft manufacturers have never considered is the fact that there is a natural barrier between India and China. This barrier is more to India’s advantage.

It has been for centuries, and has always helped them against invaders from the north. Alexander in the north west and Genghis Khan in the north, north east, east failed in their attempt to conquer India in this vast area.

And small India of today (small because India have shrunk in size) with fixed Russian technology alone, have mastered how best to use this natural barrier as a kind of early warning for all kinds of landings and take offs in China and the rest of the Caucasus.

To overcome this barrier, the shape of a stealth aircraft or any aircraft for that matter have to be modified to deal with:






thin air flight endurance

extremely high altitude performance and ability to cruise

a way to reduce intake that might be almost non existence, and cold if there is any

a way to reduce exhaust and after burner trail by mixing exhaust gas trail with cool air before releasing it into the atmosphere

a way to reduce engine and equipment malfunction at that altitude

a way to make the aircraft lightening proof

What China have now and plan to build for the next ten years is conducive for conventional op. in other areas except for robust and tactical engagement in and around the Himalayas or it’s long border with India.

India will be a little worried if China starts to build bombers and recce aircrafts like the B2 bomber and the SR-71. But then those are fast movers, not loitering birds.

Another country with this type of high altitude, thin air and early warning advantage is North Korea.











We should be more concerned once Russia start building this type of fish with “through body” air intake and “cool” exhaust dissipation on the wings, tail fins and the back.

The short answer is that neither India nor china is stupid enough to try and make each other afraid!

WHY? …..

because we both are established nuclear powers with intercontinental capabilities and none of us have a credible ballistic missile defence which any way is never 100% effective in any case!

the main answer is that the stealth fighters are the epitome of any countries power projection around the world. it can be compared to an aerial equivalent to nuclear submarines. thus it takes heavy investment as these beasts are designed to last at-least 4–5 decades with successive modernization along the way. precisely due to this reason, these weapons are mainly for first strike missions and penetration attacks! these bests are simply too costly to be put into active combat theaters and dogfight scenarios. simply put , it will be a huge waste of money if an advanced Akaash SAM or S400 Triumph, shoots down a J-20. moreover the nations like India which though lagging still having considerable heft in the high-tech industries of the world, can also build better stealth detecting radars as well as advanced air defence on its own , thereby raising the costs to benefit of ever using these expensive jets into active war scenarios!




最主要的答案是,隐形战机是世界上任何一个国家军事实力的象征。它是可以用来和核潜艇媲美的空中对手。因此需要大量的投资,因为这些武器的设计寿命至少为40 - 50年,还可以不断地更新。正是由于这个原因,这些武器主要会被用于第一轮打击任务和渗透攻击!这些武器造价太过昂贵,无法用于实战和空战。简单地说,如果J-20被先进的Akaash SAM或S400“凯旋”防空导弹系统击落,那将是巨大的经济浪费。此外,像印度这样的国家虽然落于人后,但在世界高科技产业中仍有相当大的影响力,印度也可以自己打造更好的隐身探测雷达和先进的防空系统,从而提高将这些昂贵的喷气机投入实战的成本效益!


Secondly , every fighter , no matter how good is a combination of trade-off. for example, a Mig31 is not that stealthy, but it is still the fastest fighter that could even out run the incoming missiles and hostile fighter,could also fly highest till the invention of artificial communications satellites! similarly, we all know that despite being very high-tech, F35 are quite vulnerable to basic ammunition , thus rendering it useless as a robust workhorse which the Mig21 served numerous air forces around the world. in high intensity network centric warfare, one needs disposable assets and minimum human casualties. stealth is not a very reliable factor in combat. if the fighter cant fight on its own, it is only a liability. a lesson that Americans learnt the hard way against Russians in Vietnam. so much so that they had to smuggle in a Mig21 from Egypt, to learn to how to defeat it with Israeli help.



The stealth fighters itself on its own are not going to be any use. but the use of artificial intelligence and the superior technological capabilities will be important!where J-20 loses out is the perhaps the lack of originality and the Chinese incapacity to introduce original concepts in aerial warfare, given the state of technological advancement that they have reached

See Because it was not made to scare Indian Air Force. It is part of Arm's race between USA, China and Russia. We aren't part of it. We are simple people who do yoga in morning and the walk dancing around the street to give tech support. Lol.

And even if IAF is panicked, they will tell defence ministry. Defence ministry will tell ADA. Then ADA will say “Sorry. Please buy it from Russia or france ”. But this hasn't happened. We haven't purchased any fighter jet lately. MMRCA deal is decade older.

Leave it. While making LCA Tejas we acquired 45% composite mixure to use on surface of Aircraft. Imagine this used with stealth aviation of SU- PAK T50 and HAL AMCA, which are coming soon. And also according to CHINESE analyst India will outnumber USA in terms of 4.5 and 5th generation fighters. Chinese experts explain why India and Russia jointly develop FGFA although no one knows how. (They also believe agni 5 has range of 8000km. Thanks for telling us we thought it was 5000.)

Let's look at current issue, It is not a big deal to believe that the first squadron of J-20 is not coming on Indian border. Even currently they have few Su-30 MKK and J11 which are inferior to Indian Su30 MKI. And the difference is widened when Sukhois are equipped with Brahmos. Even on their aircraft carrier as wll they have J15 which could be countered by Mig 29k and LCAs. And much more than that their carrier is not attacking India. So there is no need to worry about it is as well.




让我们看看当前的问题,J-20的第一个中队应该是不会进入印度边境的。即使是现在,他们的几架苏-30 MKK和J11也不如印度的苏-30 MKI。等到苏霍伊装备上布拉莫斯导弹时,这种差距还会继续扩大。更何况,他们的航空母舰上配备的J15,也会被米格29k和LCAs制衡。不仅如此,他们的航母并没有攻击印度。所以没有必要担心这架战斗机。

Am really glad that none of the answers here went the usual route of “Its Chinese product, its incapable blah blah”. Believe me, the J-20 is no joke and is definitely a really formidable weapon system in every sense. China possessing such advanced aircraft is definitely a threat to any country that goes confronts PLAAF in the future.

But the biggest reason IAF isn’t much concerned about it is that China is not a natural enemy of India and Chinese advancements in military is never been targeted towards India in a least bit.

Secondly, even thought its already been handed over to the air force, J-20 is not yet completely optimized to perform in its full potential. It will take few more years for J-20 to completely spread its wings. As China already stated its a system for future and India have more than enough time to catch up with that and induct our own 5th gen alternative (FGFA or AMCA) and even better surface based defense systems to counter its threat.

I think J-20’s are probably gonna be assigned for scouting missions especially the South China Sea region and probably taunt Japan and US a bit. Another possible way it’ll be used is to intercept US or Japanese aircraft in the region and maybe show off a bit. I don’t see them being stationed near Indian border at least for now.

hope it helps :)

First there are no true stealth aircraft. The technology is called low observable and it reduces the radar footprint of the aircraft making it much harder to detect. India has a well organized and professional military, the air defense organization has sufficient radars, communications, and munitions to counter air attacks, no matter how low observable the enemy aircraft are. One weakness of stealth aircraft is that they are just as visible to radars in the VHF band as any other aircraft. This means that interceptors can be guided by ground controllers or AWACS in to the area where the J-20 is close enough so that the low observable doesn’t help much. The J-20 could fly at very low altitude to go under the radar, but this will greatly reduce the range of the J-20 as it has to plow through the thick air near the surface. Plus going through the air at low altitude heats up the surface of the airplane making it more vulnerable to infrared detection.



Samved Iyer, Keen interest to fly for the Indian Air Force. Studying a lot about it.

Updated Feb 10, 2017

Because J-20 is a total joke. I never heard of stealth aircrafts having canards (the two mini-wings at the front of an aircraft thay increase lift capacity and manoeuverability. Check out a Sukhoi SU 30Mki).

If a fighter aircraft has canards, it can be very well detected by enemy radars. Stealth aircrafts shouldn't have canards.

And don't worry, because Indian Air Force aircrafts have excellent radars and so they would just scoff at J-20.

EDIT: People are mentioning about some aircrafts having canards but are still stealthy. I forgot to add in my answer one more thing. If you need a military aircraft to be stealthy despite having canards, then the radar cross section of that aircraft should be insanely small. That is not the case with J-20. Compare it with F-22 Raptor anf you'll realize. Low radar cross-section means that your aircraft will appear tiny on enemy radars.

Simply because Indian Air Force feels stealth technology as we know it now will be obsolete in next 10–15 years. And i don’t totally disagree with IAF planners too.

See the concept of stealth was born to defeat enemy aircraft detection system. But the concept has been around for more than 2 decades now, and has provided USA its full benefits. Its only now that news of Russian and Chinese radars capable of detecting stealth aircraft are coming in. Within those next 10–15 years, those radars will become more prominent , and will start showing up all around the globe.

This is more of a history repeats itself moment to me. Think of it the time when there were military planes and no radars (in the first half of 20th century). The problem of detecting planes was solved by invention of Radar. Stealth may have changed the nature of the problem a little , but it is essentially the same problem. There are “some” planes which we can’t detect using regular radars, its only a matter of time tech will come up to detect these planes and will proliferate. And the tech has already come up, it just needs time to proliferate.

You already have the answer. Because they are “Made in China” . Just kidding

1.Chinese are specialists in reverse engineering. But they have copied F22 structure and that doesn't mean they know how to replicate its STEALTH which is very essential otherwise China’s J series is just another ‘Made in Chinaware’

2.The Platforms operational capability and technical specifications are not yet disclosed or even tested for the fact

No professional army, airforce, navy will show sign of panic. India is also on the path of acquiring its own stealth jet thru a joint vanture with Russia. India dont have any reason to be concerned and china dont have any reason to attack.

People only show their narrow mindeness when they assume based on hearsay. It serves no purpose assuming that chinese pilots are inexperienced flying jet planes, Chinese can't build jet planes etc. No sane airforce will allow a inexperienced pilot to fly its multi million war plane.

Why should an entire Air force fear a single weapon system anyway? J-20 has made IAF uneasy because China has leapfrogged every Asian force here and its advantage in air is very much established now. J-20 as an addition to already formidable line up of advanced aircrafts of PLAAF is a causeof worry for all including US, this is what they have to say about J-20

Why should they fear the J-20?

Indian Su-30 MKIs have been able to track it with radar.

Indian Su-30 MKIs are faster, have 3D vector thrust, and better avionics. There is no reason to fear it…


印度苏-30 MKIs已经能够用雷达跟踪到J-20。

印度苏-30 MKIs的速度更快,具有3D矢量推力,航空电子设备性能也更好。我们没有理由害怕J-20……
