Combat radius at what weapon load and flight profile and speed + the combat radius advertised by the OEM is the radius at best suited speed and altitude and the radius of 1352 looks dubius, which could only be possible with zero weapon load, and 3 drop tank and speed of 0.9 match at 2500 feet because even f-16 has the combat radius of 500 KM with 2WVR, and 2 LGB with Hi-lo-hi profile on its internal fuel.
First how CMK 400AKG is a carrier killer which it is been advertised, because it cannot be a carrier killer because it would need more than 50 hits to distroy a carrier completely. Second can you post the link, which shows the testing of CMK 400 AKG by chinese, and its ready for deployment. Third I agree with bilalkhan777 that, it is only the marketing strategy of the Chinese for its JF-17 for its sale, because JF-17 is a pretty ordinary fighter jet, but its the weapon package which is very attractive. Last display in a some event is just a dummy weapon, it donot prove that the Missile is ready.
It needs a pretty basic understanding....
Its a carier killer caz of its speed at impact is high enough to cause enough kinetic damage to criple a large ship and take it out of conflict ( functional kill) ... same is true for df 21d...
Subsonic mussiles wont do enough damage to a carier....
It has been repeatedly steted by both pakistani and chinese officials that its qualified on jf..
This specific question was asked at paris aor show by janes that is it under testing? Answere was it is qualified and functioning....
There is nothing to suggest contrary except some egoes
