The PLAN has never built that many of a ship of this sofistication. If they did say in three years time do you have any idea how long it will take to train crews for this class ship??
It took the USN 12 years to build and comission 31 Oliver Hazzard Perry FFG's. A ship of probaly less armanment & capablity than the 054/054A.
This is why I suspect we wont be seeing any of the 54A's entering service until at least 6 months-1 year after they are commisioned. That time will be used to train crews.
