According to the ocean strategic security environment and the construction of Marine Silk Road in China, the op? eration range of China’ s MCM extends beyond the first island chain. In addition to traditional coastal / offshore MCM, the MCM mission also adds tasks such as MCM in the channel, raffic line and overseas base. In order to meet the MCM operation require? ments, combining with the development direction of international MCM technology and equipment, the existing MCM systems should be transformed and expanded by informatization and unmanned operation. The MCM systems of this unmanned era should be constructed to form fast, safe and efficient MCM power in the offshore, coastal and open sea.
