The United States and its allies limit China's forward access to the Western Pacific and North Indian Ocean by space-based satellite monitoring，surface ship monitoring，regional underwater submarine detection， unmanned underwater vehicles and the deployment of undersea monitoring array in straits to monitor and track our submarines at source，navigation routes and fjords. Based on the analysis of different submarine detection equipment，this paper presents an unmanned submarine vehicle with the ability of surface and underwater deception and attack，and the operational use for deception against adversarial anti-submarine aircrafts，deception and attack against adversarial anti-submarine helicopters as well as covering submarine to escape，providing some guidance for the development and use of unmanned underwater vehicle.
