Mine is regarded as an important underwater weapon in many countries for its good stealth performance,great damage power and high cost-effectiveness. As Chinese navy is shifting its focus from offshore defense to a combined strategy of offshore defense and open-sea protection,its MCM range will extend to open sea that is beyond the first island chain. We should learn from the MCM equipment development experience of other countries and hasten the development of organic MCM equipment to improve our fleet MCM capability and, therefore,to meet our open-sea MCM requirement.
