The command and control system is the core of submarine combat and plays an important role in the generation of submarine combat effectiveness. The submarine command system must meet the needs of submarine operations. By studying the development of US and British submarine command and control systems,this paper has analyzed the technical characteristics of US and British command and control systems,and has made some reflections on this basis. Some enlightenment on the future development of submarine command and control system has been put forward from the aspects of supporting the unmanned equipment,system structure,system intelligence and intelligent display,etc. This has certain reference value for the future development of submarine command and control system.
