This is one of those things this carrier is for, producing a new generation of naval carrier pilots. Headed to work for 002 perhaps?
China Navy a new batch of carrier-borne fighter pilots passed the assessment.
The second picture is a bonus, a good view of the ESM and ECM equipment. The first two ledges have the Type 726-2 and 726-1 ESM units respectively top to bottom. The fourth ledge has the Type 726-3 ECM equipment. But the unit on the third ledge, may not have anything to do with ESM or ECM. This is likely to be a four faced phase array, with the other two faces on the other side of the island, not radar but for high speed data networking. This is one of the changes the Liaoning had during her last refit early in 2019.
Another change is the unit on the right side of the picture. The previous one is cylindrical, and after the refit it is shaped like a capsule. This is likely to be a TDOA ESM unit like the DWL002 and is often seen with destroyers.
I use these two features to visually judge if the picture of Liaoning is pre or post March 2019 refit.
