 This advantage combined with their later completion time in comparison to Shantou, Beihai and Yulin classes have made this class more active in the reserve than the others in the naval militia, However, like the Shantou, Beihai and Yulin classes, as the new class of port security patrol boats entering service, the Huangpu class is increasingly being converted, mothballed and eventually scrapped.Just like the Shantou, Beihai and Yulin classes, many of the surviving units are being converted to naval range support boats and target drones and thus reactivated into active service as minor support auxiliaries.It can be either used as a target control boat to remotely control the converted drones, or as a drone itself.
