Possibly the first ever photo of J-11B's AESA radar. It was designed by the 607 institute and was selected after it lost out to the 14 institute's AESA bid for the J-10B because they couldn't pack the T/R modules too concisely; it's the same model used aboard the J-15 and J-16.

This is not a J-11B.

From the canapy and the wing you can see that this is just an original Su-27UBK...

Thanks for the input! BTW, how exactly do you distinguish by looking at the canopy and wings?

On a J-11B, the end pylon is specific for PL-8, we can easily distinguish it's L-form.

For the canopy, maybe I made a mistake, it could also be a Su-27SK. The reinforcement frame exists also in the single-seat version...

Another external sign - The IRST of J-11B is positionned on the right hand side whereas on a Su-27SK or Su-27UBK it is positionned in the middle.

J-11B -

Thanks for your hard work! But I'm pretty sure that the J-11B's IR tracker is in the center.
