Hopefully this isn't off-topic... Not meant as a comparison, but a baseline reference

On the topic of upgrades.
The F-22, early production F-35, Tranche 1 Typhoon are all considered "un-upgradeable".
As I understand it, this is more of a cost issue than a technical one right?

Might the J-20 vs. J-20A actually have more technical issues (or at least create more of a two-track program) due to the engine difference?

Excellent article by Yankee regarding the WS-15 flight that leaked a lot of interesting tidbits:
1. There are a lot of system redundancies on the J-20 to ensure that even if the plane has been damaged by enemy fire, it will retain limited ability to fly and fight. This makes maintenance of the earliest batch of J-20 very difficult. Later batches have significantly improved on this.
2. Later batch J-20 is a completely different beast from their earlier brethern. Despite the fact that the early batch has received software updates, after mock combat engagement with the new variant, pilots of older J-20 lament that their aircraft is a bit of a technological laggard.
3. J-20B (the twinseater) already incorporates most of the technologies used on J-20A, despite not having the target engine.
4. WS-15 will not only improve maneuverability and supersonic performance but also provide additional redundancies for onboard electronics, cooling system, and hydraulics.
5. Y-20 news -- one of Yankee's friends had the fortune of participating in a test mission on a Y-20 with WS-20 engines and claimed that he was able to get some good sleep onboard. Does this mean that the engine is a lot quieter?

The link is dead as it seems like Yankee's original Weibo account too?!!

Have these screenshots been shared before? Not sure if they're real or PSed. Does anyone have the original video?

A comment from that link:
The dry goods are as follows:
1. On June 29, 2023, the J-20 completed its first flight;
2. WS15 completed the comprehensive demonstration of the project at the end of February 2006. On March 26, 2023, WS15 has achieved batch production and delivery, and the material has been solidified;
3. The operation 20 installed with WS20 has been put into service, which is much less noisy than the original engine;
4. The domestic civil turbofan engine CJ1000A has been tested on the modified flight platform of Yun 20;
5. The basic type of J-20 is estimated to have reached about 250, and the combat effectiveness is generated rapidly;
6. The subsequent batches of the basic J-20 are continuously optimized, the air and ground handling are obviously satisfactory, and the subsequent batches are obviously more than the earliest batches;
7. The production capacity of the J-20 will be greatly increased as soon as possible;
8. The J-20 double-seat model carries out the verification of a large number of new materials, new structures and new processes, some of which are the first in the world;
9. The J-20 finished body and the new batch of F35 have the ability to compete;
10. The J-20 installed with WS15 is super powerful in combat effectiveness, allowing people to do whatever they want;
11. A new generation of fighter jets may appear in two or three years;
12. The first in the world in the early warning aircraft series;
13. Boom 20 may not be so fast;
14. Imported aviation devices have been completely replaced by domestic devices.
