As you said, we know the speed of building, but we don't know the speed of training. So the notion "ship building is faster than PLAN can take" can not be made because the unknown. It is a simple and straight logic, to me at least.
One can always wonder "if PLAN training can keep up", but without any knowledge of its training capacity, the wondering is wild guess, not much meaning really.
I do not believe the PLAN is building vessels without a clear adn concise plan to man them.
I have not seen the PLAN make such a direct and straightforward mistake to this date and do not believe they are doing so now.
Time will tell...but they clearly are operating to an overall naval buildup plan/program and that program would include the design, development, building, launching, outfitting, trials and testing, manning and training, commissionining, initial operating capability and full opeating cpability,
Each vessl in that plan, from the missile boats to the corettes, firgates, destroyers, LPDs, carriers, AORs, submarines, etc...each on of them will have a multi-year plan to lead them through that entire set of steps...which will then also include all the maintenance periods, the mid-life refits, and ultiately taking them out of commission They will have a plan for all of that. They may alter it depending on needs, particularly as the vessel goes through its entire life. But make no mistake, they have goals and milestones for all of those things for each vessel.
