The mode of maritime conflict in the world today is developing towards diversification, especially under asymmetric strategic conditions, and underwater special operation for divers is a very effective way to attack. In this study, the development of overseas diver underwater delivery vehicle technology was analyzed. The technical system and composition structure of diver delivery vehicles were determined. The development status of wet, dry, and water surface/underwater diver delivery vehicles are expounded, the sharing and key technologies of diver underwater delivery vehicles are summarized in detail, and the development process and trends are analyzed. This can provide a reference for the development of future domestic underwater special operation equipment.
