 Though this class is relatively in better condition than the Shantou, Huangpu and Beihai classes because they are preserved and maintained on land, like the Shantou, Huangpu and Beihai classes, as the new class of port security and patrol boats enters service, the Yulin class is increasingly being converted, mothballed and eventually scrapped.Just like the Shantou, Huangpu and Beihai classes, many of the surviving units are being converted to target drones controlled by larger boats such as those mentioned, and thus reactivated into active service as minor support auxiliaries.When the drones are in operation, crew departs the boat.
