J-21/J-31 Chinese 5th Generation Stealth Fighter

New picture of the J-31

Unrealistic expectations. You don't see a Boeing kinda F-22 now, do you?

J-31 is probaby meant for the Navy, so the Air force may use the same or a new project. Again, it is not necessary they will choose one from CAC if it is a new project.

Stealthkenstein...

either you dont understand English or you have not read the comment properly, i said that China will make further downgrade version for small fighter like JF-17.

It's like a twin engine F-35 without the extra fat.

It's more of stealthy Rafale than a F-35 equivalent, if we talk in terms of fuel capacity.

So, around 5 tons fuel capacity compared to 8.3 tons on the F-35?

well many chinese forums claims so

2 fighter from CAC(heavy and light)
2 fighter from SAC(again heavy and light)

and the CAC light fighter rumours were that would be single engine

How appropriate, a J-10BS chase plane for J-20. And a J-11BS chase plane for J-31....

sour grape

Wishful thinking at best... The PLAAF and PLANAF have a huge demand for 5th gen fighters, but even they cant support 4 individual 5th generation designs at once... J20 and J31 are all the 5th gen fighters China will see for a while. The only other prospect is the anticipated bomber project from Xian, and even that probably wont fly before 2016...

I highly doubt it, no need for all these trouble. CAC may well add more stealth features on J10B to make it a Slient Fierce Dragon and share some squadrons with PAF.

Nah, China won't make any further downgrade version for small fighters, no need and technically impossible, provided China may, quite possibly, upgrade in service 3rd gen fighters with more stealth feature, such as coating J10, 11, 15, 16s with RWA and make them "Scilenter"

much better

5th generation fighter and single engine are nt good unless you have a powerplant with atleast 200kn thrust

The more I look at this plane, the more convinced I am that the F35's design data really was compromised. It looks like SAC was given the F35's design work and they modified it to suit PLA requirements.

Two circa 20000lbf thrust engines instead of 1 almighty 45000lbf thrust P&W.

LERX, large trapezoidal vertical fins and bigger wings for better lift and maneuverability than the bomb truck F35.

A bigger more traditional centerline weapons bay ala J20, because of the space freed up by the lack of a STOVL requirement.

A much smoother, better shaped stealth profile and voila! a much improved F35.

Question remains though, which design can carry more fuel? Two engines will consume more than one, and the J31's larger wings may provide more room for fuel, but we'll see...

Not necessarily true. F35 can offer you tons of anti-hypothesis. Powerplant on the platform is becoming less and less important as long as stealthy striker's theatrical purpose is concerned.

China's New Stealth Fighter. Not a repeat from December 2010.
