frontally the J-20 has more reflecting surfaces than F-22 or F-35 and the stabilators called also aft tails are hidden by the main wings.

Now

The formula says Pt or transmit power is an independent variable of the equation in few words the target radar cross section is not fixed, the picture you posted is only a representation of the reflecting spikes distribution, but Pt and Frequency are factors that indicate different radars can see J-20 at different ranges

J-20 is more like a sniper plane -> Long range fast interceptor, stealthy in nature (kinda), and with good electronics and very long range weapons.

U mean details?

Not against 4th generation jets with modern avionics and wideband radars. They will be able to detect and shoot down the J-20 fairly easily due to the presence of modern wideband radars with integrated modern RWR technology. The J-20s avionics are a generation behind in reality in ECM/ECCM, when you look past the CCP propaganda, and the RCS is probably around 0.5 sq meter even in x band from the front due to canards and exposed radar/radome (to modern wideband AESA radars like on the Rafale) along with J-20s other high RCS features (in the L band it will be even more easily detectable from hundreds of kms away). The massive ranges of these new generation radars on aircraft like the Rafale combined with their modern RWRs (which will easily pick up J-20 radar emissions), ECM techniques and weapons like Meteor missile mean that they will easily track and fire on the J-20 from well over a 100 km away. If anything, given the better EMCON control on the Rafale and the Rafale's better optronics combined with the ramjet Meteor missile, the Rafale would be able to snipe the J-20 far more easily.
Honestly, even a 3rd generation aircraft can kill the J-20 easily if it's supported by an L band AWACS with decent datalinks, and has a decent BVR capability. Given CCP military's limitations due to the restrictions placed upon it by the west, most likely J-20s radar and weapons will be easily jammed by modern western/Israeli/Russian/Indian ECM.

J-20 has same details, no aircraft lack acces panels unless it is a plastic model, maintainence technicians need access panels

of course black paint blur things

Are you serious? This is mockup by some random blacksmith shop ... for "National defense eduction" show ...

Look at the background there are several older planes, J6, J7, Su27, they are all retired or mockups... That's the typical way of our community show for "National defense eduction"

Look at this J20 only steel panels, no wire no pipeline ...

For reaching the KPI of "national defense eduction", in community level the district government always just download some images of weapons and outsourced them to local small workshop, those mockup sometimes looks terrible, same as this J20.

you are lying to your self, all aircraft need access panels for maintainence, engine removal or avionics inspection, plus many other functions.

No aircraft is uniform there are gaps due to moving parts, or access hatches.

J-20 prototype are painted in black, but all aircraft can not keep a uniform smooth surface due to maintainanece accesability

I didn't lie anything, just informed you quoted with wrong images ... The images from amateur mockups ...

you are still lying, the J-31 is a prototype real aircraft

If Europe is behind how come Airbus is the leader in airliners, Eurocopter is copied by China.

I did not deny that Europe is still a developed country, and Europe still has many industries ahead of China, but the future development of Europe is gloomy.

. But they are also a good way to increase radar cross section and compromise the other stealth features. Unless the canards have to be on the same plane with the wings, they would significantly contribute to increase RCS regardless they are moving or not from 12 o'clock head on. And even if it's being aligned with the wings on the same plane and angles both horizontally and vertically, it would still contribute to increasing RCS nonetheless from a diagonal view.

the coplanar canards of X-36 are far more stealthier than J-20s canards

View attachment 98739


In the control-canard, most of the weight of the aircraft is carried by the main wing and the canard wing serves primarily as the longitudinal control device. A control-canard could be all moving or could have a large elevator. The control-canard has often higher aspect ratio and employs a thicker airfoil section than a lifting-canard. A control-canard mostly operates at zero angle of attack. Fighter aircraft with a canard configuration, such as Eurofighter Typhoon (Figure 3.7), typically have a control-canard. One benefit obtainable from a control-canard is avoidance of pitch-up. An all-moving canard capable of a significant nose-down deflection will protect against pitch-up. Control canards have poor stealth characteristics, because they present large moving surfaces forward of the wing

The J20 is not a simple canard. Its aerodynamic layout is very complicated. As for the X36, if the J20 uses this aerodynamic layout, it will be a stealth su15.

I want to laugh, you are like many people, then your eyes can measure the RCS value

I did not deny that Europe is still a developed country, and Europe still has many industries ahead of China, but the future development of Europe is gloomy.

there is a multipolar world due to globalization, it is reflected in the aerospace industry.

Europe is not a country, it is a supranational state. same is Airbus or EADS, the future of aerospace is joint programs, most Chinese program have foreign input, because aerospace is already a globalized endevour.

J-20 has even Russian engines.


Europe is not going to decline as thought, Europe has the international connections to make a world government in alliance with the USA, Japan, Israel, Brazil, etc etc.... only Russia and China resist it.

J-20 was designed as a political tool, but the reality China can not compete with the international alliances, just try to keep some degree of independence, but Challenging the west, will not win

Mexico is in the west, culturally is a western country, learn history

Ricardo Anaya is a mexican politician obviously Mexico as a multi-ethnic nation has people who are western 100%

I want to laugh, you are like many people, then your eyes can measure the RCS value

RCS is only a measument of the spikes direction, can be given upon a metric measure but the radar detection range ecuation has density power as the real detection variable

The modern international society is still an international society based on nation-states,
European industrial policies, ethnic policies, and social governance policies have all experienced serious degradation
J20 does not use Russian engines
