In addition to the J-20, AVIC is testing the FC-31, another fifth-generation combat plane, and wants to use it to tap the international market for advanced fighter jets. The Air Force has made clear that it will not allow exports of the J-20.

@Deino just came across this. Does this means J-20 will be further developed.

How much work are you going to invest in that project?Maybe stealthy nozzle with 2D thrust vector like F-22....

Chengdu J-20 to become multi-role platform
Beijing will evolve the Chengdu J-20 fighter into roles well beyond aerial supremacy.
The aircraft’s primary mission for the time being is “making way for other aircraft in an air battle,” says Zhang Hao, who heads an air force flight test centre.
Zhang made the remarks in a story carried by Beijing’s official China Daily news organ.
The type will be developed into variants and will also allow for the opening of research into a “sixth generation fighter,” says Yang Wei, a deputy director of science and technology at AVIC.
"We are not complacent about what we have achieved,” Yang is quoted as saying. “We will develop the J-20 into a large family and keep strengthening its information-processing and intelligent capacities. At the same time, we will think about our next-generation combat plane to meet the nation's future requirements," Yang added that the J-20 is “the best fighter in China, so it would be used in the most crucial moments during a war.”
The 418-word story is surprisingly candid about the J-20, which has been shrouded in secrecy since it first appeared on social media in 2010. The type made its maiden flight in 2011. At the 2016 iteration of Airshow China in Zhuhai, two examples flew above the crowd at the show’s opening, but AVIC officials declined to discuss the aircraft. The China Daily story, however, says the type was “de-classified” in November 2016.
A recent, seperate two-line story from state news agency Xinhua proclaimed that the type had been commissioned into combat service, but gave few details.
Apart from a plan to develop more J-20 variants, the story reveals that the Peoples Liberation Army Air Force (PLAAF) will not allow exports of the type. It also revealed that the type has participated in beyond-visual-range (BVR) test engagements.
It does not reveal how many aircraft have been produced, how many will be operated, or the specific missions for which the J-20 will be developed.
Observers have suggested that a key mission for the type in the aerial supremacy role will be not just engaging enemy combat aircraft, but attacking critical support aircraft such as tankers and airborne early warning & control (AEW&C) aircraft. To this end China is developing the PL-21, a ramjet-powered missile guided by an active radar. Performance is believed to be comparable to the long-range MBDA Meteor.
A guide to possible missions is provided by Lockheed Martin’s mission list for the F-35. Apart from the air-to-air mission, it says the type is suitable for electronic attack, air-to-surface warfare, and intelligence, surveillance, and reconnaissance (ISR). The F-22, originally developed as a fighter, is also capable of electronic attack and can carry bombs.
The report claims that the J-20 is the third fifth generation fighter to enter service after the F-22 and F-35. In addition, it reiterated that AVIC’s FC-31 is aimed at the international market, but gave no other details about development plans for this aircraft.
"In the past, we had to follow others' paths when it came to designing military aircraft because our research and development capabilities were primitive in this regard, but now we have become capable of designing and making what we want to have," said Yang.
An interview in China Daily with an air force test centre head, seems to indicate that further multi-role developments of the J-20 are likely and confirms that the type will not be exported, but no details were given.
Also Flight quotes an interesting part from the interview, "In the past, we had to follow others' paths when it came to designing military aircraft because our research and development capabilities were primitive in this regard, but now we have become capable of designing and making what we want to have." This may be confirmation that the J-20 did not rely on imported designs/expertise, though perhaps a bit disingenuous given number of programmes undertaken since the 1980s (Super-7, JF-17, Xian JH-7, J-10 etc.) which must have helped the learning curve somewhat.
How much work are you going to invest in that project?
Take a look at the A-10 for now. There is a reason why the A-10 was designed the way we know it today. The threat is infrared sensor-ed missile. The high locations of the engines and the overly large rudders were designed that way to minimize the infrared AVAILABILITY to IR-ed missiles.
Now look at the F-35 and J-20 regarding their engine nozzles. Both jets are in similar viewing profiles. Which jet has the greater exposure to both radar and IR sensors regarding their engine nozzles? Remember, we are taking a snapshot in time for both jets. If I am an IR-ed missile, the J-20 would be a more 'attractive' target.
Now look at this viewing angle for the F-35...
We are looking only a slight change in viewing angle and yet the F-35's engine nozzle is almost gone from sight.
For the American and Chinese designers of their respective 'stealth' platforms, they know that there will always be ideal situations for the threats but their missions are to reduce the odds of the threats acquiring the jets. For the J-20's designers, with what they had to work with, from airframe to engines, they had no choice but to make the J-20 more vulnerable than the American's jets in both radar and IR sensor views.
We are not talking about doing something external like on the F-15 and F-16 when we installed conformal fuel tanks. For what you want, if there is a shorter engine, then the airframe itself must be modified. Now you are looking at more complex issues like wiring, plumbing, weight and balances, and many more. If you want 2D thrust vectoring, you have to incorporate that into existing flight control laws, so for the flight controls avionics alone, you are looking at about 5 more yrs of development time for best case scenario. That is not speculative because yrs was how long it took the US in studying modified F-15 and F-16 with their canards systems. In the end, the US rejected the program.
The J-20 as is has been declared as deployable by China and is assigned to a front line unit, as China claimed. So how much work are you willing to put into the J-20 at this time?
Of course there is an ideal situation where the J-20's engine nozzles are not seen by both radar and IR sensors. But ideal situations are rare in flight.From horizontal angle, the engine nozzles of J-20 are also been covered by ventral fin:
i would like to say that very rare sirOf course there is an ideal situation where the J-20's engine nozzles are not seen by both radar and IR sensors. But ideal situations are rare in flight.
LOL The F-35 is just an overly rated aircraft with a SINGLE engine.
