    Possibly a hint of a carrier-based J-20 variant? This is from the same artist who posted the first drawings of the J-20 with WS-10X and the J-10 with a TVC engine.

    We're supposed to draw conclusions on China's stealth fighters based on a cartoon that looks like an early level video game boss? Haha Damn, China military-watching is hard!

    OP had a pretty good track record with the J-20 #2021 and J-10B + WS-10X, though. If we're to infer anything from this drawing, pay attention to the canard wings and the tailhook.

    I'm not saying this is stupid or unreliable, not that at all. I was commenting on how far the leakers have to go to disguise the information to avoid tea parties and how fans still manage to tease apart the message! You have to basically see an airplane in a picture that looks like Ridley (Metroid) laid an egg with Big Bird! LOL

    How do you see a tail hook? I see a tail ball.

    Yeah, I must say the leakers have taken up poetry & visual art skills fairly quickly.

    It looks like the author initially wanted to draw a hook, but later erased it and changed it to a ball.

    I am new to this site and don't know if this has already been posted, but here is some great video footage of the J-20 from YouTube:

    J-20 at Cangzhou spotted in Feb 25 photo.

    The hangars next to it are newly built in 2017 and there are 6 spaces, probably all for J-20s.

    China's new stealth fighter uses powerful materials with geometry not found in nature
    https://www.popsci.com/chinas-new-stealth-fighter-uses-metamaterials

    Metamaterials can make the J-20 an extra stealthy electromagnetic force.

    By Jeffrey Lin and P.W. Singer March 23, 2018
    China J-20 Stealth Fighter

    CAN YOU SEE ME?
    The J-20 is being deployed to elite PLAAF units. It likely uses metamaterials to increase stealth and electromagnetic performance.
    Henri Kenhmann
    China's new fighter, the J-20, uses a combination of stealth and datalinks to compete with the best fighters on the planet. Now, state media says the country is also mass-producing metamaterials for the aircraft, which could make it an electromagnetic force.
    What are metamaterials? In this case, we're talking about composite metals and plastics that use artificial geometry to influence the wavelengths of electromagnetic radiation, as well as elastic waves and sounds. Some metamaterials built using nanotechnology can also be used as super strength materials. In fact, optical metamaterials have already been used to demonstrate invisibility by 'redirecting' visible light around itself to avoid reflection, hence their frequent reference to the popular fiction of "cloaking" in Star Trek and Harry Potter. (No real-life cloaking shields have yet been demonstrated).
    China Metamaterials State Key Laboratory of Electromagnetic Modulation Technology

    METAMATERIALS
    Composite materials create electromagnetic properties not found anywhere in nature. The State Key Laboratory of Electromagnetic Modulation Technology, based in Shenzhen, is reportedly producing more that 100,000 square feet of the stuff a year.

    The metamaterials on the J-20 are likely to be used for as antennas and absorbers, given that the facility making them specializes in electromagnetic tech. Metamaterial antennas can increase radiated power, resulting in longer-range and more precise radar, as well as powerful jammers and datalinks. In turn, by fine-tuning their structures, metamaterial absorbers can be engineered to absorb specific wavelength ranges, such as those from the radars of enemy fighters and missiles. Such absorbers would likely be put on areas likely to reflect radar waves, such as the edges of canards, weapon bay doors, and engine nozzles.
    Additionally, metamaterials optimized for infrared radiation can improve the sensitivity of the J-20's infrared sensors for tracking missiles and aircraft. Or, in large enough quantities, metamaterials could reduce the fighter's own infrared signature.

    The next generation of Chinese aviation metamaterials could further increase stealth, improve communications, sensors and jamming, and even lighten airframe weight. Yang Wei, the J-20's chief designer, told the People's Daily that China is already laying down the requirements for a sixth-generation follow-up to the J-20. Much as the USAF's envisioned futuristic Penetrating Counter Air platform, too, will likely include much more metamaterials.
