Interesting that we have yet to see the land-attack variant of the YJ-18.
A land attack version would be simpler than the antiship version. It would forego the second terminal stage so the cruise missile is a single piece whole tip to tip. Without the rocket stage, you can extend the fuel tank all the way further, which will increase the range of the missile. The missile will be subsonic in its entire flight, and will have a blunt end compared to the antiship version having a sharp tip. It looks more what you would expect a conventional cruise missile would be, with the bottom half recognizable as being shared with the antiship missile.
Yes, I know what a notional subsonic LACM would look like, but it's interesting that we haven't seen it yet.
