Looks like a big conscious shift in focus to get ships to the fleets ASAP instead of optimising scheduling as was previously the case (you would normally want to stagger construction so you don’t have a lot of ships all entering service in a short time frame as that would not be efficient for the shipyard or naval academies supplying the new manpower for those ships).
I think this is an indirect sign of just how seriously Beijing is taking the threat of actual war with the US right now.
If a war doesn’t break out, I think we will see a big and distinct break in the trendline of PLAN warship construction and commissioning next year, when the impact of these production schedule changes start to filter through into fewer new built hulls appearing.
