The low observable is interesting. Just looks real close to the USAF low observable.




Nice fighter too...but I would not call it a true 5th gen stealth fighter. I am sure it is much better than the standard flanker...but not up to speed IMHO with true fifth gen stealth fighters. Here's the side and front compared to the F-22:

Really depends on if this aircraft actually exists.

SAC's said to be working on this "silent flanker," a strike version of J-11BS, and an entirely new stealthy 5th generation aircraft developed from their rejected J-XX proposal as well. I have a feeling one or two of these projects might be the same thing. We'll know soon enough I suppose.

not too bad if they made some more out.china can't only 1 new fighter they need more to choose for

Be a nice aircraft to upgrade and make a naval variant for the carriers. A few years from now, if they bring out a carrier variant to upgrade the J-15s. Depends on the perfromance and charactoeristics...but a naval variant would be an option I would think.

The thread starter's pic is just pure fan art.

And yes, there is definitely a new twin-engine heavy 5th generation fighter under R&D at SAC, this is confirmed in Li Tian's recent published book. (Li Tian is the chief scientist at SAC/601th insitutue and a senior fellow of the academy of engineering of China).

The fighter will have conventional layout with large leading edges and large wings, this is based on a early proposal for the J-XX project, not merely a stealth su-27.

SAC's 5th generation stealth fighter is largely self-funded, most of their sub-constractors, save the engines providers , are these who have also failed the J-XX competitions, so it is kind of a league of "losers".

The success of SAC's upcoming stealth fighter is crucial to AVIC group, since J-20 project using open bidding to decide their sub-contractors, which means a lot of companies outside of AVIC won the contracts. (e.g. J-20's AESA radar provider is 14th insistue instead of AVIC's own Insistutue of Radar and Electoncs Equipments).

Meanwhile SAC's stealth fighter will limit their sub-contractors to AVIC's other companies/factories, thats whay AVIC decided to self-fianced this project, therefore the cost of this fighter may not be significant lower than J-20.

According to the more reliable source (the guy who successfully predicted the time of the maiden flight of J-20 and other details, milestones about J-20 in 2009), the fighter is otpimized for multirole purpose, unlike J-20, which is a dictated air-superiority fighter, but SAC's fighter can also do the 4S requirements for the 5th generation fighter, althrough at a lesser degree.

However, the guy also mentioned that SAC's mutli-role stealth fighter will like to face tough competition from another AVIC's design insistute, 603th insistute, which is expected to develop a stealth heavy fighter-bomber, place more emphasis on stealth, low-cost, and larger internal weapon bay size, at the expense of inferior dog-fight performance.

And according to the same source, SAC's fighter is near complete in 112th factory now, and it is likely to seeing the light by the end of this year.

So, "J-16/19" vs "JH-7B". The bigger question is "is the PLAAF requesting fighters to fill those roles?"

IF they're privately funded the SAC and XAC are probably hoping for PLAAF interest. I'd think PLAAF are already commited with J-20 for their future AirDom fighter but there is a potential spot for a future striker.

It's pretty good if so. Keeps the two companies busy and fresh while providing PLAAF with open options. Also PLANAF could be interested in SAC's plane for their future carrier fighter. I really wish we knew how many of the projects we see have PLAAF backing and how many are "private".

Anyway, I can not wait for the reaction of foreign press and "analysts" when this SAC plane is "revealed". The sheer fact it will be stealth should probably make them soil themselves, and as it sounds like it will come out just a year after J-20... well :rolleyes:

Unfortunately, I sense some of the usual bias against SAC in some of the posts here. Claims are that this SAC J-XX will meet more of the basic 4S requirements than F35, T50.
Such a plane will have a big role in PLAAF.
