A two seater J20 variant commanding an assortment of reconnaissance and fighter stealth drones would be interesting. Thanks
Yes, that's the plan.

seems China has been dominated the new cold war...
In the video of the J-20 taking off with the two WS-15 engines it takes off in less than 200 meters. That's a really short take off, which means the engines are powerful.
That’s roughly about 1 G acceleration fully loaded.

A J-20B with empty weight 38,000 lb and installed thrust 82,000 lb might be one of the quickest jets ever built.
Look at the frontal cross section area to get an idea of the aerodynamic drag. Clearly the J20 has low aerodynamic drag. And at high speed drag is a crucial parameter. A 10% improvement in drag is equivalent to a 20% improvement in thrust. Considering how large the wing/lifting surface is, it should fly fast at high altitude where air is very thin. A key question is … how much thrust from engines at extremely high altitude?
WS-15 is beautiful
China has come a long way ... keep improving ... never forget the two centuries of humiliation
Nicely explained.
Good watch, many thanks.
currently the f35 can only sustain super cruise for 10-15 mins depending upon altitude, weapons and fuel load. the f35 is still drastically under powered in comparison to the j 20.
F35 can't even go pass mach 1 for too long before it's coating starts to peel off
@@fatdoi003 ...the yanks don't intend to use the f35 supersonically on the attack. it's skin gets too hot and is easily detected by infrared optics. it needs that speed for the exit rather than the ingress. and even then the f35 is too slow to escape. a rand study found that the life span of the f35 is around 6 mins once it is detected by a SU 35.
f35 can't turn, can't climb, can't run and can't go far...according to the american general accounting office. bottom line: the f35 is a turkey.
Both you guys don't understand air power doctrine. Yes the f35 is underpowered compared the j20, but that is an intentional choice. The J20 is so underpowered compared compared to the f 15 and that's a jet from the 70s. Power isn't all that important in aerial combat. Being able to get a kill further beyond visual range is much more important. Radar and extending the kill chain in much more important. The f35 is truly a marvel of engineering.
@@cocodog85 worst still F35 rear aspect is not stealthy plus it runs the hottest fighter engine
@@corpmex F35 is just a money making machine failure... Only 30% is mission capable... pilot training is lagging behind as the turnaround time between sorties takes too long
Those not well informed will not realize this, but a 25% increase in thrust does not mean a 25% increase in performance. It’s more.
T/W is an important statistic, but it’s very simplistic. A better stat to understand is Excess Power, which is T/W combined with drag, also known as the lift to drag ratio.
We’ll use made up numbers to make this easy to understand, though please not that what I’m saying is a simplification almost to the point of being wrong, as thrust and drag change with altitude and speed. Say your jet weighs 100 units, and creates 90 units of drag at Mach .95, 100 units at .99, and 150 units at Mach 1,6, while having 180 units of thrust dry and 240 units on afterburner.
This gives us an excess power of 40-50 units just below Mach, which is used to accelerate or maintain speed in maneuvers or a climb. If our excess power did not exceed the combined weight and drag, the plane would not go supersonic.
Now let’s fit new engines. These engines make 240 units of thrust dry and 300 units on burner. Our engines (and inlet aerodynamics which decrease drag in a super cruising jet, which is why you can’t just put most powerful engines on a old airframe and expect supercruise) now allow dry thrust sufficient to maintain speeds of Mach 1.5, and more excess power for accelerating, maintaining speed while maneuvering at supersonic speeds, and climbing and maintaining high altitudes.
So now you can see why a 25% increase in thrust gives you more than just 25% more performance, it changes how your plane flies. Most people fail to explain that supercruise isn’t a button you press, but a dynamic part of the design.
Not just plain sea level thrust numbers matter but the thrust at speed and altitude... which are all secret
@@keithw4920 hence why I said that.
@@jacobbaumgardner3406 Yeah I was just replying to one of the comments but think I hit the wrong button. Too many armchair experts just look at static sea level thrust numbers. Even the thrust to speed/altitude graphs for commercial engines are hard to find, much less military ones.
The WS15 engine produces 25% more than the older WS-10. The J20B has now higher performance than the raptor F22. China is rapidly progressing in engine design and manufacturing of high bypass engines such as the WS20. The J35 which is aircraft carrier based jet fighter equipped with WS19 will be more powerful than the usa’s F35.
This is the reason Americans are working on NGAD

if j-10 is fit with Ws-15 that plane can shoot down any twin engine plane. it can go mach 2.5 easily. WS-15 is expected for newer upgrades at 210 to 230 tonne trust and 8000hours before replacement
J20 can supercruise with WS-10C in limited conditions.
Another REALLY REALLY good analysis, I was wondering, could the JF-17 get the WS-15?
no, the engine too large for JF17... but it can fit into J10C
Maybe ws-19 can fit.
no, size not match
no way
F414/RD93/WS13 has similar dimensions, and classified in the same class.
F110/AL31/WS10 are in the same class.
F119/WS15 are in the same class.
F119 and WS15 has extremely low bypass ratio, which means they consume a crazy amount of fuel. if somehow put in if 17, it would need to refuel every 20mins.
The F-35 does not meet the US definition of a "5th gen" plane as it cannot sustain supercruise. The multi role "all weather" F-35 "Lightning" II cannot fly within 25 miles of a lightning storm. The F-35 Joint Program Office still has not lifted it's flight restrictions more than 2 years after issuing them.
Compared to the F-35, China's J-20 has superior range (5500km vs 2200km), it's missiles have superior range (300km vs 160km), superior payload, superior speed (Mach 2.55 vs Mach 1.6), superior engine thrust (362 kN vs 191 kN) and superior service ceiling (60,000 ft vs 50,000 ft) and more modern avionics.
362 KN of thrust? Where did you get this information?
@@CulturalXplorer19 WS-15 engine has 181 kN thrust. J-20 has two of them. In comparison F-22 engine has 156 kN thrust for total of 312 kN.

Are you Philadelphia zombie that often take a horse drugs?
So the F35 is crapt?
China is making advancement in aviation engines and stealth fighters ... these things like F-22 are usually not shared with anyone else. However, China may share these technologies with countries like Pakistan, Argentina, Iran, Saudi against India, UK, Israel ...
Certainly!
China is levelling the playing field!
China is the tide that raises all boats!
Most can't afford it. And even if china offers, it won't be anytime soon. China wants every jet they can get asap.
Also if they get j20, they will need to be repaired and linked to Chinese network, just like USA does with f35. China isn't going to be selling them to even Pakistan for 2-3 decades at least, after China already has 6th gen and much better tech available. Same way USA doesn't give anyone f22 and only f35 since they can control it through software and networking.
J35
LOL, can't stop laughing, more "great china" stuff please :))))
Let me conclude the advantages for both jet. The advantage for the F35 is actually their production capabilities. It is relatively cheap with advanced electrics and battle management system and can be produced in large numbers. The US believes the advanced electronics can overcome the disadvantages in fly performance for the F35.
For the J20, the advantage is what a typical heavy fighter has over a mid weight fighter. more range/payload/faster/higher/bigger radar/better flight performance. And probably more expensive too.
Lets keep in mind, when J20 was designed it was designed to counter the F22/35. When the F35 was designed, it designed to counter all 4th gen.
The F35 disadvantages include poor reliability, exorbitant life cycle cost, failure to meet watered down spec requirements, and the latest hardware upgrade is so screwed up, the government is refusing to accept them. If you believe everything the government and military contractors say, then ask yourself why do they want to get rid of the F22?
My replay was shadowbanned. I guess adding specifics on why the F35 is a disappointment and contrary to the F35 sales pitch must upset the censors.
@@douginorlando6260 what are you trying to say. all the specs are online.
The F35 is relatively cheap?? Relative to the F22 yes, but not the J20. And the J20 is a heavy fighter with twin engines AND more advanced avionics, EODAS and more powerful AESA radar because of its size. There is a reason why the F35 is called a Money Pit.
@@laowantongchau Yes less than 100million is relatively cheap for a 5th gen. J20 will be way more expensive after purchase power adjustment for the rmb.

Looks really cool
It's had been proved that the WS15 was more power output(that means faster) and fuel efficiency than F35's engine.
one mistake: the type of J-20 with WS-15 is J-20A, the streamer in the origin video show that
WS15 has 3D thrust control ability
Yes, I stand corrected
@@EurasiaNaval i don't know much about airplanes but are those canards on J20 still needed with these new engines?
@@zackwang9314 I don't know
@@zackwang9314 In short, no they are probably not needed anymore but they won't harm and will stay there.
To change the aerodynamic design on an airframe needs tons of work and wind tunnel tests not much less than design an aircraft from scratch. If the canards are removed, they probably need to move the delta wings forward and add a pair of horizontal tail wings. It's basicly a completely different aircraft in terms of aerodynamic. Besides, the canards which provides lift can make use of the excess power from the WS15s to make maneuvers we've never seen before.
Just look at F-16, It was first designed in the 70s, but the most recent batchs looks almost identical to the 50 years old ones aerodynamically wise. Or in the case of Flankers, the canard equiped Su-33, even though really small ones, flys differently from any other older or newer Flankers.

Best jet fighter in the world today. Incredible.

@@SkrenjaOh the saltiness. Simple, tell me which jet is better and why?
Why do some planes fly with 2 different engines? Like you saw at 2:09, the 2nd picture shows the 2nd engine to be different, wouldn’t that cause thrust imbalance?
I think they readjusted the throttle mapping to level up all that.
And since the engines are not far away from each other, imbalances are not that great......
@@brownguy9135Oh thanks!
They are testing the new engine by pairing it with an old one.
reliabilty test.... you don't want both test engines to go lights off on you in the middle of the test.... usually one engine is prototye and the other a production engine
Newer experimental engine is paired with production grade engine to minimize risks of crash due to engine failure. Twin engine planes are designed to fly on one engine in case of engine failure, if the test engine fails they can still fly back home on the other engine.
I don't think the f35 can super cruise.
Lessons learned include the aircraft and the manufacture of the aircraft. That’s why I expect among next generation designs,there will be one designed to be efficiently mass produced using a next generation factory. Eliminating the pilot, high G maneuvering and many internal systems, a 1/3rd price aircraft with 3 times the production rate cold provide next gen capabilities for a large percent of missions (not all missions).
A single WS15 thrust vectoring engine could eliminate nearly all control surfaces, have 1/3rd the frontal cross section of the J20 for 1/3rd the drag, light weight for low wing loading and improved performance at very high altitudes. 1/3rd the drag with 1/2 the thrust of a J20 provides sqrt(3/2) top speed or 22% faster and very comfortable supercruise. The ideal ubiquitous airframe to launch long range guided munitions including next gen extended range PL15
I expect China to develop a twin WS15 engined aircraft designed to do one thing well … launch large missiles at maximum speed and altitude. Forget about stealth trade offs, range trade offs, high G trade offs, maneuverability trade offs. Eliminate many internal systems that add cost, weight and volume (possibly including eliminating the pilot). Just one game changing mission (in effect, adding a reusable first stage to many of the missiles and rockets in inventory).
Don't they have an AAM called the PL-21 in development that can target bogeys up to 400km out?
Some Chinese colleges and universities already have some crazy scenarios about future hypersonic bombers, let me share one with you: A bomber powered by TRRE engines carrying ballistic glider warheads with no booster, only attitude control engines, accelerate itself to Mach 6-7 inside the mainland of China (which means it can't be shot down when low speed) and then release the glider. The warheads can travel up to 2000km with the initial mechanical energy and impact on the target with Mach 5. Since there is no booster the missile would be much smaller than the ordinary hypersonic missiles in 2020s
@@EthanX1aoIt’s a very obvious prize. I would not be surprised if several countries are working on it behind closed doors. I’m sure lots of bright engineers collectively will systematically consider all the possible variations and trade offs and come up with a viable approach and then later evolve/refine/upgrade it into an even higher performance solution.
@@swedhgemoni8092 Yes, the PL-21 is suppose to use ramjets instead of rockets so have far higher sustained speed and endurance. It should increase its range and no-escape zone considerably over the PL-15, far longer than the Meteor and AIM-120. Maybe the future AIM-260 can match its performance. Which means it will be a true AAM that can take down fighters at long range. The current longest range BVR in the PLAAF is the PL-17 at 400km which is basically an upsized PL-15 and cannot fit in the J-20 bay but can be carried by the J-16. It is likely going to be used to bring down HV targets like tankers and early warning planes, or maybe unsuspecting fighters.
J16可以更换更大引擎的。如果有需要，可以升级。
What would a J20 variant look like if it was going to avoid close encounter dog fights?
1… a much smaller canopy for better aerodynamics, less drag, more efficient super cruise.
2… lower G turns would reduce structural weight by thousands of pounds, plus increase the allowable weight of large munitions (at 2 g instead of 9 g, a 2,000 kg munition load point would now handle a 9,000 kg munition).
3… eliminate the side weapons bay holding short range missiles on each side to free up internal volume and reduce complexity. The high speed allows escaping danger
4… a stretched weapons bay would allow flooding an air combat zone from below the horizon with supersized long range air to air missiles. Or if the air to air missiles forgo the booster stage that provides below the horizon launch at low altitude from far away, this variant would count on stealth from the front quadrant to flood the air combat zone with PL21 or PL15 missiles launched from less than 300 Km away, then escape at supersonic speed if danger approaches. Or the air to air missiles with boosters are launched a high altitude supersonic speed,then high value targets 600 Km away have only 6 minutes to run.
5… the enlarged internal weapons bay would carry an anti ship missile, or some kind of air to ground payload that benefits from a high speed stealth delivery platform.
Well done China J-20 Super WS-15 powerful Engine.❤❤💪💪👏👏👍👍💯💯❤❤
The F-35 has thrust vectoring and supercruise?
No
China will likely retrofit all J-20's with the WS-15 once the engine is declared complete and development/testing cycles are over, as this is the final power plant for the J-20 and any new engines will likely only be developed for it's 6th generation fighter.
I'm looking forward to more information coming out about the J-35's progress.
It's not worth retrofitting the old J20s with ws15, changing the engines means refitting air-intakes, which also means a big surgical operation to the whole aircraft. Just produce more new J20s, we don't lack the money or the production capacity
@@EthanX1ao Of course it's worth it, if you don't understand why you shouldn't be commenting, even America does this with it's engine upgrades.
Whatever the cost is to swap engines, it is substantially less than simply building new J-20s, China has around 200 J-20's presently there is zero chance that those will simply be abandoned, it makes no sense to service 2 different engines on the same jet as well the rather obvious bad idea of having the majority of your fleet be under powered.

@@潘公子-o5m That is my understanding as well, though the cost issue has been addressed or at least I have not heard anything more about it, if you are Chinese and follow the project I would like to know if you have heard anything about it presently?
There is a mistake here, the serial number of the replacement WS-15 is J20A, and J20B is the two-seater version of J20
You are right it is a J-20A, although note two-seat version is called the J-20S or J-20AS
The upcoming J20B production batch may get the WS15s and achieve super cruise. The improved low drag of the J20B may allow supercruise even if the engine performance is de rated by 10%. This leads me to believe the WS15 engines will be allocated to the J20B over the J20 batches. Most likely, the WS 15 will still not quite reach the touted performance goal and require engine overhauls every 100 hours until they build up reliability data.
In fact, the new batch will be named J20A
Unofficially, the lifespan of WS-15 Turbofan Jet Engine is around 4000 hours and that was the reason that WS-15 is starting to replace all WS-10C & Russian AF41 Engines.
I bet it can supercruise even with WS-10s. Would probably be a trash plane if it couldn't.
Great news if WS 15 engine is ready for J 20 it means it is also ready for J 10 fighter
There are three big questions regarding the WS-15 engine:
Does it meet the power output goal?
What is the fuel consumption?
What is its durability?
With regards to the first question, I suspect it likely meets the design power goal.
Its fuel consumption, which impacts range, may take a while to figure out. I would not be surprised if they are still tweaking the design for better fuel efficiency.
I do not think anyone, including the PLAAF knows the durability of the engines, especially the turbine blades. That takes a while to determine and often after an engine has been in service for a while. Squeezing more power and efficiency usually hurts durability because both increases the temperature and stresses on the engine.
I can summarize your questions into one : does it beat the raptor?

I do not think f35 can super cruise
The F35 can super cruise, however it has to use afterburner to reach Mach speeds but once at Mach it can maintain its speed without afterburners. The thing about the F35, is how it fights and the amazing American sensors and technology used to seek its prey. American technology is far superior than Chinese!!!
@@nateford4504 So true, wish you can say the same about American Warships.
fat Amy can maintain the speed with its momentum....
@nateford4504 yeah that's a reach. By that same logic any supersonic aircraft with AB can super cruise. Burn to mach 1+ then cruise till you lose speed. The simple fact of the matter is that the f35 can't super cruise but it does have very good energy retention.

We won’t buy any stealth aircraft until India gets them first. No need to start an arms race that you will lose.
As a friendly comment you left out some crucial ideas from your video. According to what we see on Wikipedia as well as non-official Chinese sources, WS-15 has a slightly lower thrust at full military power compared to F119, thus J20 may exhibit somewhat inferior performances at supercruise compared to F22. Also WS-15 is expected to consume fuel at a higher rate than WS-10C due to its lower bypass ratio. The new batch of J20 will feature significant upgrades to its electronic warfare suites including a new generation of AESA radar. It is expected that some of the capabilities of the J16D jammer will be adopted. A gun has been rumoured to be included as well.

You're referencing Wikipedia? That's US intel propaganda.
维基百科白痴，中国没有公布的东西查维基百科😂
This has to be the first time i heard someone saying that engines determine if the plane is 5TH generation
It's one of the determinants. I did not say it's the only one...
well considering 5th gen and 6th gen have specific targets and requirements like stealth and supercruise etc, you can see why this engie determines if the J20 is fully in the 5th gen requirement bracket..... youve got naysayers saying J29 is 4th gen +++++ etc etc, this NEW engine which has been cooking for 20 odd yrs puts any doubts to bed
Sustaining super cruise is one requirement for 5th gen fighters... So F35 can barely be termed 5th gen
if you consider F-35 as a 5th gen, it shouldn't matter tbh
Engine tech has always been a huge factor in generation leap in fighter development.
The best fighter jet in the world 😊

I won’t be surprised if a new J20 production line is dedicated to producing a variant designed to carry a large anti ship missile inside. It would be 90% identical to the J20 and therefor cut years off of development and benefit from mass produced Components/subsystems for the J20 family.
No room internally for a useful anti-ship missile; make room and it's no longer a J-20. It can't even carry the A-A PL-17..
@@tw4982 the chief designer of the J20 proposed a wide variant years ago. And not every anti ship missile needs to be a back bone breaking “carrier killer”
@@douginorlando6260 ..and hasn't built it. By definition, anti-ship missiles are meant to be "stand-off". Make it smaller, and the launching aircraft becomes the target. No, the J-20 will not waste its time shooting boats..it's focused on air dominance...
@@tw4982 modern tech employed by DJI for cheap makes targeting specific weak points a reality. It only takes 10 Kg of precession placed warhead to cripple a key capability like the Aegis radar. Or penetrate into a missile warhead on a ship with a shaped charge. Or penetrate inside the captain’s control room, etc. the J20 is designed as the ideal ambush platform … high speed, long range, stealthy from the front, large weapons bay with heavy payload (compared to f35). It doesn’t even need a unique variant considering the volume available by replacing the PL15 missiles with 2 large anti ship missiles with longer range than the PL15. A variant with a larger weapons bay just makes it more effective and I assume China has been developing it.
@@douginorlando6260 Wugh..the J20 has been flying with a small entourage so far..he can't ambush if we know he's coming (Stealth is wasted as soon as you key the mic). And not a single respectable A-S weapon the Chinese have worthy of damaging a ship will fit in the internal bay. Besides, even if you could get within 10-15 km of a surface combatant undetected, why would you only launch a drone?
F35 cannot supercruise without redlining the engines. it is not rated for supercruise.
It needs to light the burner to reach mach 1 first
Thanks - I deleted that. I was wrong
Awesome 👏
So it has a total of 200 KN of dry thrust as well as over 310KN wet thrust, which is similar to F22 raptor. China has almost caught up. F22 just has better stealth and manoeuvrability compared to J20, other things are same.
态势感知与雷达系统和数据链能力F22均落后于J20
F22's only advantage is better stealthy. J20 has more range, better radar, environmental sensors, and speed.
Is that a J20 or a yellow rocket? OMG!!!
This is J20A not B yet, WS-10 and AL31F all J-20
copy which country? which country has the technic
not the US that's for sure ..too woke ..
@@patrolmanracv China engines suck Worse
The main gap between the J-20 and the F-35 is stealthiness; though the larger, more powerful radar on the J-20 somewhat offsets this, open source physical RCS modelling shows the Block IV F-35 to still retain a non-trivial detection range advantage even assuming American RAM is merely equal in effectiveness to Chinese RAM, which is unlikely to be the case.
If the stealth performance of the J-20 is not good enough, Taiwan and Japan, as well as the US military bases, how come they have never released information about the discovery of the J20! On the contrary, the commander of the US military base publicly admitted that the J20 discovered the F35 and flew close 😂😂😂, 🇺🇸🐶 too much

The WS-15 service life is purported to be 3600 hours before overhaul, while the Pratt & Whitney F135 is purported to be 6800 hours of service before overhaul. Thrust to weight ratios are also a mismatch between the WS-15 and the F135. The high tolerances and materials are the key to the F135s dominance. China is not able to replicate essential parts that meet the stress requirements, because they lack the materials nor can they meet the high tolerances necessary. So, try as they might "Made in China" still means low quality regardless what they might copy from the west.

Well done china❤❤
I wonder what they'll do with the hundreds of WS-10 engines that get pulled out of the J-20s if they all get swapped to WS-15. Maybe they get sold to Pakistan?

F35 flies on a single engine, attaining Mach 1.6 speeds. J20 requires two engines to reach Mach 1.8. Even on afterburner. China should apply itself to improve metallurgy, which may raise its stature.
maximum speed comparable to cruising speed?
@@bitboy22 comparing speed with and without afterburner. F 35 and F 22 can both attain Mach1 without afterburner, or super cruise. Not sure about J20. Nobody trusts Chinese claims. F22 attains Mach 1.8 in supercruise mode, Mach 2.25 with afterburner. Not sure what F 35 supercruise speed is.
@@redrust3 F35 does not have super cruise capability. As for the J20, you have a preset position of distrust, what else to say,

Amerykanie wyraźnie czują respekt wobec J-20. Ich doktryna przewiduje panowanie w powietrzu tak więc im wiecej J-20 a w przyszłości J-35 tym gorzej dla nich. Nie należy zapominać o opl ! Trzeba tego sporo każdego piętra oraz wielu systemów radarowych. Rozwijać Marynarkę. Jesli chodzi o wojska lądowe to artyleria lufowa i rakietowa oraz wojska pancerne. Na MBT konieczne są system obrony aktywnej! Nie porzucajcie Rosji ! Powodzenia 🇨🇳
upgrades!
Sour grapes. Go read up on the J-20's capabilities, which far exceed those of the F-35 and F-22, before you make a joke of yourself.
I really hope the new engine is reliable tho. So far I’ve only seen a CSIS conference on Chinese engines which was very condescending tbh. The hurdle for fighter engines (airplane engines in general) is not necessarily being able to produce one but much rather having them to be reliable and secure for employment which is a metallurgy and production quality problem.
Seem like the rumblings on the internet is that the engine is as reliable as western and Russian engines or else it cannot pass the tests to be fitted on the J-20. But the metallurgy tech in China is still a tad behind the west so the engine lifespan is lower, rumored to be around 3000 hours compared to the 4000 hours of F-135. It will fly properly but China will have to build more of it to make sure the fighter fleets have enough engines to use.
@@gelinrefira well I do really really hope it’s more reliable than Russian ones. I do believe Chinese tech is at this point overtaking the Russian in a very wide variety of capacities. Maybe only excluding the nuclear sphere?
@@gelinrefira Good reply. Do you have any sources where we can read more of these rumours? Or are they all from weibo?
@@accountantthe3394 At least some of the sources are directly from wikipedia. Which is why I say they are rumors because unless you scour the Chinese part of the internet to find the primary sources, nearly everything on there is secondary. But they also have no reason to lie about the capabilities of these engines. The PLA and the Chinese industries want the world to know where they stand and how fast they are progressing.
you can put a big engines ever, but they have to overcome a giant superstructure, this so called gen 5-th, is way biggest ever built, more bigger than F-22 and F-35, not to mention the forewings, how on earth you will ''stay'' stealthy with that ?
I’m sure the life cycle of the engine is comparable to the current Russian engine. About 1/3 the western engines. I’m happy they have 2 engines for those long flights
Since you are so sure, why don't you share your "Top Classified" data so that we all know🤣🤣

Big congratulations to PLAA for achieving super cruise, something the USA hasn't done since the 1970s .
nah， F22 is still the best 5 gen figher ever built
no TVC for WS15 now
No need. Canards already give huge aoa advantage in bvr. The j-20 isn’t made for dogfighting like f22 or su57.
@@MuhammadAli-255 ok, not going to discuss here.
Aircrafts are just as good as its crew 😂😂😂😂😂😂😂😂
F35 is not supercruise.
Technology is mastered in civilized countries
Probably the most telling evaluation of this latest engine for the J-20 and the J-20 itself is the American and Taiwanese reactions... Which is basically no reaction.
I'm sure everyone is watching developments closely but as the WS-15 was introduced and being installed (reportedly fleet wide), there has been absolutely zero comment publicly by Taiwan and the US. I doubt neither was surprised that the engine had been developed to the point that China was putting extreme faith in the engine. But you don't hear about requests for an aircraft better than the F-16V on order. You don't hear about additional air defenses than already exist and are planned.
So, is this new engine something to be concerned about? How can this engine even perform at the high end of its specs considering China's lack of advanced materials and manufacturing knowledge? If a J-20 engaged an F-16 or maybe just a missile fired at it and had to push the engine's limits, would that mean an immediate engine replacement after return to base?
My baby❤
Everyone should be expecting stealth aircraft to be dropping cluster munitions … except instead of a cluster of hundreds of small bomblets scattered over the battlefield, the cluster munition will scatter hundreds of Hunter drones that systematically attack everyone in the extermination zone. And DJI should be able to deliver 5 million military drones per year to PLA
The f35 doesn't have a super cruise . It can hardly go super sonic so not fifth generation according to this.
