ONI's document on the PLAN has specified YJ-18 as a point of interest, and a variety of news outlets have picked up on it as a "carrier killer missile".
Ignoring all that, I have a bone to pick with ONI's claim that YJ-18 is simply a reverse engeineered 3M-54E missile, and their stats seem to have taken numbers directly from the 3M-54E (Klub-S export version that PLAN bought).
The video footage we have of the supposed YJ-18 launch from the test ship has a vastly different geometry to 3M-54E...
Then there's how rumours of YJ-18's range seem to be in the higher range of 300km-400km rather than a measly ~200km. Given how YJ-62 alone has a range of 400km I would be surprised if any new generation AShM didn't at least approach that kind of reach.
In fact, they seem to have gotten their numbers for YJ-18 directly from deagel, which isn't exactly known for its accuracy regarding PLA hardware:

I feel like many western defense watchers have interpreted discussion on the Chinese internet of YJ-18 being "China's Klub/3M-54" as being "China has reverse engineered Klub/3M-54". At this stage of course, things are still up in the air until we get clear pictures of YJ-18 however what limited evidence and information we do have suggests to me that ONI (and many other outlets) have got their facts wrong in this case.
