With so many capital ships built at such a short duration, how are they going to manage the repairs during the mid life of the ships?
It appears there are separate and dedicated shipyards that handle the repairs and refits exclusively.
Example is the Type 051B 167 Shenzhen. This ship is built in Dalian. The refit of the ship is done completely somewhere else.
Its also just like we saw the Type 052C no. 150 being repaired, same shipyard that is doing the refit for the Sovremenny 137 Taizhou, which also has the two stripped Type 054 in that area. That shipyard has also done hull repairs on drydocks or mobile docks on other Type 052C ships.
