No it will be not..its frontal aspect stealth is ruined due to presence of Canards and as far rear aspect is concerned presence of conventional engine outlets ruins it too.
time for some learning for me.. just the basics if you will
why having canards is bad?
how does it increase its radar signature. When it has a relatively small size and if has the same RAM coating and shape uniform to the rest of the craft?
Does that make SU-37 Terminator and Euro-fighter bad as well? why do they have canards? If canards help in sharp turns & other swift manoeuvres then whats wrong with that?
Surely canards cant be as bad as having open weapon bays? Secondly how does an F22 compare without canards?
Does it have something in addition which basically means it can do without canards?
Finally does it suggest that Chinese had a design/ technical barrier which meant that canards were the only (cheap/ easy) option to provide whatever performance benchmarks were set while designing this craft?
Does F-22 raptor have RCS (reaction control system) like space shuttle? Where the nose can be nudged right and left? If there are any jets on the face of the raptor then maybe I am too old notice them.
Finally a laymans view
Looking at the J-20 side by side with say T-50 or raptor it is clear that the designers have gone for a trade off between how much they wish their J-20 to be and what technical & knowledge base they have in addition to the resources. It is hard to match with America which spends about the same or more on its military power than the whole world combined.
What say you?
