The invention provides a diving/buoyancy power/gliding (missile/torpedo) system to overcome the defects of existing torpedo carrying systems. Compared with existing various (missile/torpedo) carrying systems, the diving/buoyancy power/gliding (missile/torpedo) system has the advantages that production and use costs are quite low, and especially, no life sacrifice of combaters is caused. The system is simple and reliable in structure, simple in arrangement and has an advanced combating strategy of discovering targets, actively attacking and acquiring combat successes in the first place, realizes microminiaturization, unmanned operation, intelligentization and non-characterization, and has good hiding performance since gliding to approach targets through buoyancy energy. After completion of attacking tasks, the system and a controller are automatically destroyed. The system is especially beneficial to offshore water defending, oceangoing blocking of important waters, ship routes and ports and striking and intercepting of invasive large and medium surface ships and submarines. The system can improve offshore defending capability of Chinese navy, and is especially applicable to striking and restraining of large and medium surface ships and vessels.
