Thanks. I was going off Wikipedia's designation, and don't know the full list of variants and their designations.

Would you know CEP for the 9X variant?

Based on pictures the CEP should be very small, centimeters maybe. This missile doesn't explode, instead it send 6 blades at the target. Pictures show direct hits.

I'm well aware, and that was my take, and I was initially going to write "within a metre", but couldn't find substantiation of that. The Hellfire itself offers the 5m value.
