It’s derived from their CSS-5 intermediate range missile and uses technology similar to that of the Pershing II, which had a CEP in the single digit meter range.

The current version has a range around 1800 km and a nuclear warhead that weighs around 600 kg. I imagine an anti-ship (carrier killer) version would have a similar range and a similar weight warhead.

In any case if one of these hits a flight deck at mach 4 or so, the warhead is guilding the lily.
