Something from ShiLao podcast today. They mentioned that J-16 performed really well in the military exercise in Russia (Zapad 2021?). In the final part of the competition, it not only did better than su-34 but had the best ever score in ground attacks. Quite impressive when considering that Su-34 is more attack focused than J-16 and has more combat experience.
I really wonder what that amounts to considering the exercises with Russia virtually always only involve dumb bombs and unguided rockets.
I suppose if the metrics of the exercise include target acquisition with offboard datalinking, which would require the aircraft's avionics suite to do a bit of work including the aircraft's radar to perform SAR mapping, that might explain it.
I don't recall J-16s going to Russia carrying any targeting pods.
