[0002] Targets provide maritime targets for naval artillery, missile live-fire shooting or simulation training, and are important maritime equipment for maritime target shooting training and exercises, as well as for testing and evaluating the strike effect. Therefore, the development, product iteration and deployment of targets are of great significance to the development of naval weapon equipment technology and the improvement of combat capabilities. Traditional targets generally use abandoned ships, requisitioned civilian fishing boats and special steel-structured target ships, which are costly, slow to deploy at sea, slow to recover, difficult to tow, pollute the ocean, and cannot be deployed on a large scale. The existing inflatable ball targets are simple and fast to deploy, but once they are damaged or scratched by external forces, the internal air pressure of the entire inflatable ball target is insufficient, and the inflatable ball target immediately fails and must be re-deployed, wasting personnel, time, financial resources, and seriously affecting the progress of training or exercise subjects.
