which J-11B is quite deadly already
Which country/ies have better operational plane than J-11B in the region ?
No 1: US Navy (F/A-18E/F and F-35C)
No 2: USAF bases in Japan that can field F-22 and F-35 if necessary as well as older F-15 and F-16.
No 3: IAF. I know people here don't think much about it, but don't forget they have nearly 250 Su-30MKI. Those are very formidable aircraft either WVR or BVR. These are equipped with PESA radars, Israeli Jammers, TVC and more.
Others but in smaller numbers,
No 4: RoKAF (F-35, F-15K)
No 5: JSDAF (F-35)
