With the rapid development of naval unmanned combat platform technology,the intelligence and unmanned trends of various weapon systems are inevitable. Unmanned underwater vehicle will be one of the most important equipment in future operations. It integrates high technologies such as detection,navigation,positioning, energy,propulsion,new materials,new technology and intelligent control. It can play the role of force multipler in modern sea warfare,and improve the capoblity of systematic operation. Due to the danger in anti-mine operation,the combination of unmanned underwater vehicle and MCM technology is an important developing direction of mine countermeasure in the future.
