    Hmm, engines don't look very much like the 117S.

    It looks more like WS10A than 117S. That is what perplexing me.

    From Huitong

    The J-20 #2001 prototype was photographed when it was preparing for high-speed taxxing trial at the CAC airfield on December 22, 2010. The prototype features a pair of all-moving tailfins and ventral stabilzing fins, and the laters are expected to be removed on the production models. It also features F-22 style air intakes but with DSI bumps installed at the upper corners, as well as a one-piece canopy. First disclosed by US Office of Naval Intellegence (ONI) in 1997 as XXJ, J-20 is the 4th generation multi-role fighter to enter the service around 2015. Since 90s both CAC/611 Institute and SAC/601 Institute had been working their own designs for a twin-engine multi-role heavy fighter with stealth capability and maneuverability comparable to American F-22. It was speculated that 601 Institute was working on a "tri-plane" design based on canard/conventional layout/V-shape tailfin while 611 Institute working on a design based on canard/tailless delta wing/all moving V-shape tailfin/side DSI/bump inlet layout. All designs were expected to feature an internal weapon bay to reduce RCS, which has been speculated to be <0.05m2 (head-on). It was also rumored that J-20 could initially be powered by two 13,200kg/WS-10 class turbofan engines with TVC nozzles which would result in a normal TO weight exceeding 20t. J-20 also incoporates an advanced FBW system fully integrated with the fire-control and the engine systems. Its fire-control radar is expected to be AESA (Type 1475/KLJ5?). The aircraft may feature a "pure" glass cockpit (a single F-35 style color LCD display and a wide-angle holographic HUD). Many of these subsystems have been tested onboard J-10B to speed up the development (see above). Russian assistance has been speculated in terms of softwore support for calculating the RCS of various designs, as well as the rumored supply of Salyut 99M2 turbofan engine (14,000kg class) to power the prototypes, if the domestic engine (such as improved WS-10A) fails to meet the schedule. The overall performance of J-20 is thought to be superior to Russian T-50 (stealth) but still inferior to Amereican F-22 (electronics & supercruise). It was reported in November 2006 that a T/W=10 17,000kg class turbofan (WS-15/"large thrust") is being developed for J-20. In August 2008 it was reported that 611 Institute was selected to be the main contractor for the development of J-20 and 601 Institute as the sub-contractor. Subsequently a full-scale metal mockup was built at CAC. One rumor in May 2010 claimed that 611 Institute started to construct the first prototype, which was expected to fly by the end of 2010, even though the full configuration model won't fly until a few years later. The latest news indicated that the first two prototypes (#2001 & 2002) have been constructed and the first high-speed taxiing trial by 2001 took place on December 22, 2010.

    Sounds like this source thinks that it's stealth will be somewhere between the PAK-FA demonstrator's and F-22's. Kuku, there's the lead that you were speaking about...This thing comes out 20 years after the F-22 and is still expected (according to this source) to be inferior is avionics, stealth, and supercruise. Much respect to Lockheed Martin and the rest of the F-22 industry team.

    If it is true, and the PRC, it's aviation industry and the PLAAF can pull it off, this J-20(?) could reward the PRC lucratively in terms of $ and influence around the world. For traditionally, Chinese weapon's have been cheaper than either U.S, French, British or Russian.
    Add to this the PRC's willingness to sell what ever weapons to whom ever (even more so than the Russian's!!), they may stand a chance of opening up a whole new market for air forces who are in the market for a 5th gen fighter, which has stealth characteristics, super-cruise, advanced avionics and sensors..................
    It will be interesting to see if the PRC can get this so-called J-20 moving faster than the Russian T-50 PAK-PA.
    This will also mean that the USAF will seriously have to consider a relook at its F-22 and or its replacement!!

    For what's its worth, even Richard Fisher of the "China is selling J-10s to Iran" fame thinks that Beijing recognizes that selling the J-XX is too destabilizing.

    Initial Observation. It is huge! Bigger than any current PLAAF bird?

    Either huge fuel tanks or weapon bay. Wonder if current Russian 117 engines provide enough powere for such a size of a bird.

    I would assume if they stick with a single seat config, PLAAF would prefer a bigger weapon bay compared to endurance.

    So a stealth bomb truck? Still a PLA Airforce?

    Also it is painted in black/grey. Unusual for a prototype to be painted in grey. So this is as much a Chinese aviation moment as it is a show for the world.

    Taiwan should be knocking on the door asking the U.S. F-22 urgently.
    With the new 5th generation fighter Chinese Taiwan will need at least the F-35

    why do i find this statement so hard to believe. The people are getting help from Russia in the first place.

    Zinja: ripped-off F-35 / F-22 technology; and the Russians optimized for high maneuverability with reasonable front-end stealth.

    The most relevant point, I think, that was made against the Chinese J-20 is that the J-20 is likely to be extremely difficult to manufacture and maintain. The Chinese may be able to further improve their manufacturing technology between now and the time the plane enters IOC, but that's not a given.

    Well, this is a disappointment. From additional pictures, it appears as though the J-20 doesn't opt for a lambda-wing arrangement. It's just a YF-23 rip-off, with diamond wings.

    There is a difference between ambition and accomplishment. Their attempts might be ambitious, but their achievements might be limited by their technological capacity. Let wait and see.

    We have close pictures from CDF. It's a trapezoidal wing. It's awful; with the wing size I'm seeing it looks as though it would have a completely pathetic wing loading. 400kg/m^2 would be lucky.
