There is a difference between when a ship is technically commissioned, and when it is fully worked up and operational in the sense of being a fully efficient unit
I think it is not unlikely the 003 will be physically complete by the end of 2022, and there would follow some period of preliminary trials to ensure what is a new type of ship for the PLAN exhibit no fault attributable to the quality of work at the ship yard. Once that trial period, maybe 6 month, is complete, I suspect the ship will be commissioned, around middle of 2023. After that, there will be lengthy period, maybe 2-3 years, when the ship is put through her paces to enable all the bugs in the preliminary CATOBAR operating doctrine developed before first practical experience can be gained is ironed out. So it might be 2025-2026 before the ship might be considered to be fully efficient and sent on operational deployment on something more than trial basis.
