I see the other way around, J20 will jam F35 since J20 is more powerful than F35. if F35 tries to jam J20, j20 will fire missile and take it down since F20 will see further and can kill longer distance.
F22 has its legs too short, 500KM is nothing and if you fight against China you can not refuel around 500km radius. China is not Iraq. for F35, it is not air-superior fighter, J20 is specified on air-superior and focus on pointing only 2 objects, f35 and f22. none of f35 nor f22 is specified to fight J20 since J20 is newer version.
I have never been a fan of the F-35 and I strongly believe that it is a weak aircraft. But only when price is taken into account.
These are gross overestimations and underestimations and they have no realistic basis.
At this stage one must consider what exactly is the J-20 ? Right now nothing more than the Су-47 Беркут. An aircraft being tested that is painted black !!!
Back then the Russians suggested initially that the Su-47 will lead to a production aircraft, time however showed that it was just a valuable technology demonstrator. At this stage it may turn out the J-20 is nothing more than that!
There isn't a single thread of evidence that the J-20 is superior to even an F-16.
Why should it be?
*because people claim it is VLO? -- do we know it is? at this point in time we have no idea, and black paint stealth does not make.
*Better avionics? -- says who ? Chinese fanboys? Have we seen the J-20 avionics efficacy? Do we know how it reduces pilot workload or even if it does? Do we know if the intended radar for the J-20 has any actual combat worthy capability? Do we know what modes and with what level of efficiency it provides? The western & russian companies are already talking about reducing the LPI effect of modern radar systems on RWR hardware. How do we know the J-20's LPI will be even a factor in its operation?
*What is this nonsense about range ? As if you guys know which engines the J-20 will be flying with! The fuel consumption is very much dependent on the engine profile used and the mission profile. You will be surprised to know that there are two kinds of ranges, the ferrying range and the combat range.. vastly different animals.
*And then we move into the most ridiculous territory ... "the J-20 will shoot the XX-XX down long before..." .. how??
even if the J-20 "sees" a target on the radar and acquires a lock .. it is the missiles seeker that needs to find the target too.
if the missile seeker is not up to the task you can kiss your $%& goodbuy whatever you fly. ...
There is currently no air to air mid range or otherwise EM guided missile that can hit a VLO target.
The very way mid course guidance works means there is a window of failure there.. and if planes like the Su-27 and the EF2000 can take advantage of it, a VLO target has even more of a chance.
