The concept,classification and characteristics of time-sensitive targets are analyzed. The advantages of using submarine forces to strike time-sensitive targets,the methods and timing of striking typical targets are discussed combined with the characteristics of submarine operations. Finally,based on actual situation,suggestions are put forward from the aspects of battlefield situational awareness,integrated data communication,combat command system,submarine warfare tactics,and construction of time-sensitive information firepower system. These suggestions provide a basis for making up for the insufficiency of system construction,and for further improving our navy’s ability to strike time-sensitive targets.
