Abstract:The command and control system is the core of submarine combat and plays an important role in the generation of submarine combat effectiveness. Submarine command systems must meet the needs of submarine operations. By studying the development of U. S. and U. K. submarine command and control system, this paper analyzes the technical characteristics of U. S. and U. K. command and control system, and makes some reflections on this basis. Some enlightenments on the future development of submarine command and control system are put forward from the aspects of supporting unmanned equipment, system structure, system intelligence and intelligent display. This has certain reference value for the future development of submarine command and control system.
