Does China have a pla version of CM-400AKG? Like a YJ-something?
Or is it export only missile
The nearest publicly known PLA air launched "ballistic missile" to the CM-400 is the YJ-21 which has only been photographed on the H-6.
The JL-1 ALBM (not the JL-1 first generation SLBM) is quite a lot longer ranged and faster but even the YJ-21 appears to be a class above the CM-400 when it comes to speed and range. Both relatively simple weapons despite being modern ALBMs like the Israeli LORA and Russian Kinzhal. I don't think there are any other ALBMs available on the export market except the CM-400AKG. None of these missiles are gliders and probably have very limited maneuverability, if any at all.
The YJ-21 however, does have maneuverability. It is an anti-ship missile and ship or H-6 launched. CM-400 is small enough to be carried by the JF-17. I don't think PLA is that interested in getting manned fighters to carry any CM-400 equivalents when these will be so limited in speed and range even if they attain a similar level of ability to target moving ships as PLA's "heavier tech" equivalents like the YJ-21.
