    The new warplane – which is almost invisible to radar – will be ready to join China’s active fleet “in the near future”, the country’s air force has said.

    Experts suggested the futurist craft had already joined the service after photographs emerged supposedly showing it taking part in training exercises.

    But the military claims the J-20 – seen as a direct rival to Lockheed Martin’s F-22 Raptor – is still undergoing tests.

    In a statement, China's air force described as "unreliable" reports that the J-20 had appeared in training exercises, following a weekend state television broadcast that showed grainy pictures of what some viewers took to be the aircraft.

    "At present, the J-20 has yet to be equipped for air force service," the air force said on its official microblog late on Tuesday afternoon.

    Both the J-20, and another new aircraft, the Y-20 transporter, are still being test flown as planned, the air force said.

    "In the near future, the J-20 and Y-20 will, in succession, be equipped for service, effectively raising the air force's ability to fulfil its mission," it added, without giving a timeframe.

    China expects the J-20 to help narrow the military gap with the US.

    But experts say China is struggling to develop advanced engines that would allow its warplanes to match western fighters in combat.

    China has rapidly been ramping up research into advanced new military equipment, including submarines, aircraft carriers and anti-satellite missiles – which has rattled nerves regionally and in Washington.

    Another stealth fighter – the Shenyang FC-31 Falcon – is expected to ready for combat in 2022.


    In a statement, the Chinese air force said: "In recent years, China has mostly been relying on its own strength to develop new armaments, one after another.

    "This is a completely reasonable requirement to protect the country's sovereignty, security and territorial integrity and protect the nation's security developments.

    “It is a necessary guarantee of effecting peaceful development."

    J 20 is a piece of a shit. It has not the capability of age old 3rd generation plane and it has nothing fifth generation including engine, Radar or Avionics. It has poor aerodynamic and lots of design flaws. A chinese engine was planned but it has failed. It has a lots of vibration and wings are short. Canards eats away its so called stealth, It has poor aerodynamic and lacks the capability to maneuver quickly.

    China still relying on Russia for its engines. Considering the billions spent on its defense industry, it has yet to achieve any competence in engine design. Until it does so, it will never achieve military independence.

    Technical question.

    F-35 (or F-22) has rear horizontal stabilizers but does not have front canards. J-20 has front canards but does not have rear horizontal stabilizers. Which one is likely to be more agile?

    Maybe @Bahamut can answer this one.

    I think this will will help
    1. A canard generates upthrust when pitching nose up, while a traditional elevator generates a downthrust - thus a canard should allow for better sustained turning performance.

    2. A canard can generate a little upthrust in steady level flight, allowing for a smaller wing - meaning less inertia & damping, thus better dynamic response rates (in pitch and roll).

    3. A canard when pitching nose up will induce a downwash over the main wing, reducing its effectiveness, which conflicts with (1) and (2). Increasing the distance from canard to wing can help offset this (Eurofighter).

    4. A canard can be used as a replacement for a LERX for high AoA flight, and its normally more efficient in cruise. Close coupling of canard and wing helps achieve this (Rafale).

    5. With a canard, the main wing can be placed further back, hence the c.g of the aircraft is further back, hence the gear is further back, hence more aggressive rotation angles can be used for take-off. The canard also is better at inducing rotation than a tailplane.

    6. A canard requires a junction between wing and fuselage - this junction is harder to hide on radar. Its preferred to hide this behind the main wing on an elevator (like the F-22).

    If I remember right, canards generally give better agility, but other design features would also have to be factored in.

    Also canards discourage "stealth", but that shouldn't be a problem as stealth will probably be obsolete in the coming deacdes.

    Still leaves out the doubt. How are canards in relation to rear horizontal stabilizers? Which one of them give greater manoeuvrability (I know many other factors are involved but assuming we can generalise & differentiate between the two)?
