AS I said before, J-20 radar is way better than F-22 radar, but some people here seem to be in denial.

China and Japan ahead in radar technologiesChina demonstrates absolute leadership in AESA radar technologies, driven by innovations in semiconductors such as GaN and GaO.

I always like to mention that in GaN, they developed a 2.4 kW chip with an optimized design (V-shaped gate and aluminum integration) and the first 8-inch N-polar GaNOI wafer, considered half a generation ahead of conventional GaN.

Without exaggeration, this places China at least 5 years ahead of the US, which still uses GaAs in the F-35 (one generation behind) and plans a full transition to GaN only in 2030, resulting in a current gap of about one and a half generations.In GaO,

China has produced 4- and 6-inch wafers, a level matched only by Japan, reinforcing the Asian protagonism in this sector. A large part of this advancement is due to Russian technology transfer, followed by a strategy of controlling exports of critical minerals.The US has some researches to reduce the gap and can also invest in Japanese research centers.

What is the difference between prototype and LRIP? I thought J 20 had long passed the prototype phase. The fact that 6 of them now use WS 15, according to him, should qualify as LRIP, as he said, without quoting me.
We know WS 15 is real, we have a photo unveiling the first test of J 20 with WS15 as shown on the banner

I am not so sure about WS 10 C2, that is the Sinodefence crowd designation and not official. You can believe what you want. I have no problem with it

That's exactly the point since you don't care about facts and established procedures ... if you looks at any Chinese fighter, they always have several prototypes usually - at least by CAC - as:

J-10: 100x for the prototypes and 101x for the first variant, 102x for the second variant ... and so on!
J-20: 2001 for the demonstrators and 201x for the first true prototypes, 202x for the second variant ... and 205x for the J-20A variant!

Again, the LRIP aircraft usually have a different numbering systems denoted by CB00xx construction numbers ! The first true serial production batch for the J-20 was CB01xx and so on!

Shenyang uses a similar system, if you check the construction numbers for the J-35:

350001, 350003, 350005, 350006 for the known prototypes and 00xx numbers for the LRIP aircraft (the naval ones) and 01xx for the first serial batch (J-35A).

Therefore again, you are wrong to assume right after the prototype 01 2051 the next ones are LRIP aircraft. For the J-20A altogether 2051, 2052, 2053, 2055, 2056 & 2057 are confirmed.

And again you are wrong when you just repost an old post from Hurin without checking the current understanding, namely that in fact only one prototype actually uses the WS-15 - no. 2052 - whereas all others are using the regular WS-10C (2051) and from 2053 on the improved WS-10C2. If you negate this designation since it does not fit your wishful-thinking, it's your issue, but that does not make any other but no. 2052 using the WS-15!

300 J-20s!?

Wow. Man, just give PAF a cheeky Sqd....

Now show me the official statement that the current J 20A now uses WS 10C2, Other than chatter, so-called "insider" aka sinodefence crowd! They always cite an unverified Chinese forum chatter or Weibo post to justify their skepticism toward any Chinese achievement.

Do you have OFFICIAL SOURCE that J20 equipped with WS-15? and deino is far far more reliable and authentic than you on Chinese military aviation you fan boy

Deino is not privy to the Chinese secret. He, like everybody else, depends on the forum to get info. Like they say in the land of the blind, one-eyed man is a king!

I would concede to him if he could show me a statement from an official of AECC.

Here is the latest AECC official statement 2023
As of early 2023, the Aero Engine Corporation of China (AECC) has officially announced that the WS-15 turbofan engine has entered serial production and is "ready for mass production". The engine is designed to power the later variants of the Chengdu J-20 stealth fighter jet.

Key developments regarding the WS-15 engine

• Production bottlenecks resolved: In March 2023, an AECC official, Zhang Yong, stated that China had overcome all technical obstacles related to WS-15 production, including issues with advanced alloys for high-temperature components.
• Ready for mass production: Official announcements were made in both March and April 2023 confirming that the WS-15 was ready for mass production.
• Flight testing: In June 2023, a J-20B prototype reportedly made its maiden flight with twin WS-15 engines installed. Test aircraft powered by the WS-15 have been observed since at least March 2022, with clear photos appearing in 2024.
• Improved capabilities: The WS-15 is expected to provide the J-20 with supercruise capability—allowing it to sustain supersonic speeds without the use of afterburners—along with improved maneuverability. This is a significant upgrade from the interim WS-10C engines that initially powered the J-20.
• Ongoing challenges: Despite official claims of production readiness in 2023, some reports in late 2024 suggested potential supply chain issues for the advanced alloys needed for the engine. However, the development reflects a major advance for China's indigenous aero-engine industry.

I quote the official AECC ! The maker of WS15
Hurin's post is relatively recent, September 27
2057 is J-20A, now confirmed and may even be part of some AB via 太湖军I名/wb

You are posting some AI generated summary and think that's true? You are really a joker!

Yes, the WS-15 is THE engine for the J-20A and therefore it was also shown on that placard, but from all we know - not via SDF and not from me but from the well-known credible guys you should know on Weibo - the first prototype to use WS-15 engines was actually no. 2052 ... and to yet unpublished reasons, all other including the J-20AS twin seater and all LRIP aircraft are using WS-10C2 or whatever you want to call them, but definitely NOT the WS-15.

And regardless how much AI-BS you try to create this does not change it.

I quote the official AECC ! The maker of WS15

There is NOTHING official available, not that they use it or that they don't use it ...

Do you read your post before posting?

I quote the official AECC ! The maker of WS15

And they said only one prototype j20B equipped with WS-15 for testing in your above post

Who are they? No, it is not AECC that said that, but Deino!
It all started with a post on Sinodefence stating that AECC is having trouble with their supplier or needs to change suppliers. Something like that. So they can't produce WS 15; instead, they produce WS 10 C2. Now, who do you believe, the AECC official or the random post in the Chinese forum?

Honestly, I'm just asking you a honest question: Is this a game to lie and spread misinformation by picking only what you like and ignore what you don't like or are you just a troll?

So, WHO are you to think you could deliberately take whatever post you like and ignore whatever you don't like and still think you are THE BIG PLAAF specialist?


Based on your own words quoted - and in fact NOT giving the source, but just a random quote, that could also be fabricated - it is a typical vague post by a company!

Here is the latest AECC official statement 2023
As of early 2023, the Aero Engine Corporation of China (AECC) has officially announced that the WS-15 turbofan engine has entered serial production and is "ready for mass production". The engine is designed to power the later variants of the Chengdu J-20 stealth fighter jet.

There is not a single word mentioning "the first prototype is using it" or "already all J-20A prototypes are being tested with that engine" ... in fact the last sentence is a claim, a projected hope for the future, namely that "The engine is designed to power the later variants of the Chengdu J-20 stealth fighter jet."

Interesting is, if you check the few images available, only no. 2052 has the WS-15 and all others not! So again you just overinterpret what you would like to read from a future prospect as a given fact for today!

You are funny! The first prototype already flew in 2022, so this statement is barely valid for the first one! No. 02 aka 2052 flew in June 2023 and as such is related to thsi post, but since all others flew later again without the WS-15, how could this report know that there are maybe issues and all later prototypes needed to use the WS-10C2?

So in summary: Now, who do you believe, the AECC official claiming something in early 2023 that is at best very much vague or a well-founded post in a Chinese forum by a credible poster who gets his information via the most credible guys on Weibo or you, a confirmed fanboy who doesn't care about facts or chronological order, who regularly posts BS simply because it fits his worldview but contradicts all known facts and can NEVER admit to making mistakes? So who would you believe?

Look your post above AECC Is clearly stated that only one prototype equipped with WS-15 for testing

And you want to untested and unfinished WS-15 to be mass production for its intended platform J20

You're really a bad fanboy
