Are we even sure that something in that design form even exists for one the YJ-18 variants, and isn't instead capable of both dual anti-ship/land attack missions in the same missile rather than being separate variants? I remember reading a comment that you posted in another thread from a few years back, and you said pretty much the same thing. But, it's not like images/videos of YJ-18 launches from PLAN ships are rare, there's plenty. Yet all of them show YJ-18 with its pointier end, but none with a rounded end like a CJ-10/Kalibr/Tomahawk LACMs.
So, I think either such a variant for primarily land-attack missions with that design doesn't exist, and instead the YJ-18 missile is capable of both dual anti-ship/land attack missions, but at the same time, we do know the PLAN does land-attack exercises/drills, but in all of the YJ-18 images/videos over the years, we've never seen such a YJ-18 variant with a rounded end that is strictly a LACM. Assuming it does exist, I can't really see as to why they'd hide such a thing if the reasoning is political/message wise. A YJ-18 AShM is still an offensive weapon, and they've published numerous images and videos of it being launched over the years. I believe there's even one video showing a YJ-18 hitting a target ship?
