Where you have see ?
Completely franckly... I don' t see how you can say it with China in 1980's Budget, economy.. ! for material 3/4 obsolete and completely and plans for 50 years !

Not really if you consider that SAC split the production of J11 derivative into J16 and J15. We know that since 2014 they have produced 20 J15 and 25 J16. that is 45 jet in 2 years .The J15 production rate seem to be in locked step with the launched carrier, but they need to crank up more pilot.They need cheap,economical trainer jet
Estimated Number of Aircraft Pilots Trained vs need (Source: East Pendulum, August 22, 2016)
Anyway apparently PLAN has chosen the JL9 as trainer plane.Using J15 for training doesn't make sense
From Henri K blog
In a new GAIC statement issued on November 29, it is reported that the Chinese aircraft manufacturer continues to work on the naval version of its JL-9 supersonic training aircraft, known a priori as the JL-9G.
GAIC General Manager Wang Fei (飞文飞) gave a speech on November 26 to nearly 300 senior executives of the company, in which he said that "the JL-9 is going on the aircraft carriers" is part of Of one of the GAIC's six strategic opportunities in the 2017 development plan.
It is unclear at the moment whether this means that the Chinese navy finally confirmed the choice by taking the JL-9G as its first naval training aircraft, or WANG simply wants to "transform the test" in 2017 after several years of development Of the program, knowing that the HAIG (Hongdu Aviation Industry Group), which is also a subsidiary of the AVIC group, would have positioned itself to propose another candidate based on the JL-10, better known under its export name L-15.
In any event, the JL-9G seems to have already gone off with a considerable advance since at least one of the prototypes, registered 423, has already been photographed in flight with a landing stick (although it was Proved later that the current JL-9G cell is not adapted to the braking with a stop strand and a complete review of it is therefore necessary), to which is added videos showing another prototype Took off on a springboard installed on the ground.

The fact that all the key components of the JL-9G, notably the WP-13F and then the WS-13E, are Chinese also give it a significant advantage - the JL-10 is now dependent on Ukrainian engines and this situation is disconcerting. The Chinese military, even though the native WS-17 engine, developed especially for this twin-engine jet aircraft, is already in flight test state.
Some people also question the safety level of the JL-9G as an airplane, as it is a single-engine aircraft, and it is derived from J-7 which has a high landing speed.
However, the single-reactor aspect does not seem to be a particular problem for the US Navy, for example. The T-45 Goshawk is also a single-engine aircraft and, thanks to several aerodynamic optimizations, the JL-9G's landing speed is reduced to 210 km / h, well below JL-9's 260 km / h, 230 km / h of Su-33 or 250 km / h of MiG-29KR for example.
And from my analysis a few months ago, if the Chinese navy can not find a solution to increase its training resources now, there will be a shortage of qualified naval pilots as soon as they receive their second aircraft carrier by 2019 The gap will widen at this rate with the arrival of the 3rd aircraft carrier after 2023 if nothing is done by then.
The JL-9G thus constitutes a viable solution in the short term, so that the training campaigns of the Chinese naval pilots are more economical and can be launched on a larger scale. The J-15s could then be freed from their training role today and devoted to more "operational" missions.
It is therefore for all these reasons that it is not surprising that the Director General of GAIC calls this a "strategic opportunity" for his entity. It will soon be known in a few months whether a new version of JL-9G,(with the cell and the train reinforced? did he meant structure)is available for a real landing on the carrier Liaoning.
The case to follow.

That is just what is necessary. Will there be a new version of JL-9 able to withstand cat launch? Probably while the fuselage strength is increased to accept the forces of an arrested landing that too can be provided.
There is of course no production plant for J-15 that is brought into operation when an another few aircraft are needed. There is a plant that can switch between the production of batches of J-15, J-16 and soon perhaps J-11D.

The initial requirement is for 24 aircraft for the CV-16's air wing; you don't need a fully-fledged production line for that. The next batch of 24 aircraft would be of the upgraded J-15A for the CV-17, but since carrier construction takes a few years to complete, I doubt there would be a "production run" of J-15s in the same sense of the term as there would be of the J-11D or J-16.
What does this mean? Is Henri K. suggesting that JL-9 might actually be reengined with WS-13 ?!? While great in theory, wouldn't that be too much work? Engine itself might not be as much work, as its actually a bit smaller (some ballasting might be needed) but air intakes might have to be changed to allow for greater military thrust offered. And not by little, but by 30-40%. Does JL-9 even have enough internal space for the air duct leading to the engine to be sized up that much?
If somehow that can be pulled off - it'd really make JL-9 go a full circle. From a fighter, to a trainer to a platform that's good enough to be a fighter again, even competitive to JF-17 in some regards.
But ultimately I'd say i just misunderstood the article, it does sound like too much work for not enough gain (just the naval trainer, and for export there is always JF17)
I think it's meant to be that there will be a JL-9 variant that will have WS-13E, not that any of the current airframes currently do.
that is how huitong is saying it, and I agree that it makes sense in this case
Of course, i didn't even think it could be understood that it's already a done deal. It could only be an ongoing or future engineering project, where jl-9 is redesigned from the ground up to accept and fully utilize a more powerful engine. Still the question remains - is it worth it? How long will it take? Could jl-10 with domestic engines be ready in the same timeframe? And so on...
It can't be just redesinging the rear fuselage, as Huitong puts it. It would have to have the whole body of the plane redesigned and its internal structure changed, as well as intakes and the engine interface. By how much is the question.

maybe slow, but where do you want to put the extra J-15s that you wish to produce? There is only one CV-16 and only a handful qualified pilots.
thanks for the video. I don't really agree with the video's notion "JL-9 to fill the gap of J-15 due to its slow production". USN uses trainers for landing and taking off from their carrier, that does not mean F-18's production is too slow.
