It is a surprise to me that the WVR are same as on J10. They have huge RCS (not that it bothers a flying door like the Flanker) and the range is rather limited compared to other Russian options. At the same time I would have expected these WVR on the JF17. They surely never showed up there. Is it because China signed an agreement with Israel or something totally unknown? I have to agree that China does not send this latest tech to Pakistan.Why sending J10 and SD10 if this minor issue is very strict? I am not intrested in discussion whether who gets what or latest but it surprises me that this particular WVR is a very clear non delivery item...
